Question

I spoke to David Power @ PE about the remapping of the ECU today. He explained to me about the process involved, all seems fine as far as I am concerned. Is there anyone out there who has had this done? I would be most grateful if I could have your honest opinions about the conversion before I go ahead! I would like to know how different the power delivery is and anything else that might be of interest!
Even better if there is anybody near me willing to show me?

Maybe somebody will have a better suggestion?

Thanks for any help you offer!

P.S. D.Power sounds like a nice chap, he suggested that I place this post rather than him put me in contact with a customer! I take it that he has a lot of faith in his products!

I think most people on the board will struggle to give you a better alternative.

Bob Isles has had his 98MY done there and had a heartattack on the way home (not jokeing).

Come along to the dyno day on the 14th Aug at PE. Lots of Scoobies. Some with PE remap. Speak to the owners and meet Dave. If you crack before then, put your car on with the rest.

I have the PE phase 1 performance package.
I currently have 261 BHP @ 5760
and 267 LBS/FT Torque @ 3600
If you look at one of my power runs you will notice that @ 2700 the car is almost at full torque.

I have the PE phase 1 on my MY96 Sti wagon. Figures on Pauls dyno site. I can truly say this is one of the best upgrades that you will find anywhere. Every car is different and every car is upgraded specifically !!

A lot of money ? yes but well worth it and completely safe !! (Not like the Superchip and other upgrades)

Shouldn't PE export their stuff to Japan? Lot's of people there tune their cars and remapping the CPU is very popular. I guess they can do good business in Asian countries provided the product is promoted well.

Question

Dave,
Am I right in thinking that the PE remap doesn't add any additional hardware, it's an ECU remap tailored for an individual car, i.e., your dealer wouldn't know (unless he drove it !). Also is it possible to map the ECU such that the top end power is unchanged, but the torque is improved - in other words, when you phone your insurers and tell them you've had your car "chipped" adn they ask you the power increase, you can tell them that there is no maximum power increase.

Cheers

Andy

Hi Dave,
Thanks for the confirmation. It's what I thought you did but wasn't entirely sure.

Thanks

David,
How much torque is it possible to get from an STi V (gulp!)
I'm sure the reason the STi is quicker is cos of the extra torque.
And any news on the V remap?

Cheers

Craig

FAO David!

Do you have a REMAP for the ver 5 yet?
If so, what costs are involved and how much time would it take to complete?

Regards,
Graeme

At last I've found a forum that is discussing the PE ecu upgrade.

I'm very interested in this, as I'm getting a little used to my MY98's power, and would lurv for some more urge.

I have several questions, I have listed them below:

1. As the ecu is programmable, I understand that the top end power can be limited, but with good torque gains, sounds good, but what about fuel? Presumably some gain is had by re-programming for SUL, can it be programmed for normal UL but still with some torque gain? I think BBR did a turbo conversion for the MX5 in which they fitted a SUL or normal UL switch in the glove box.

2. Warranty. I obviously value my warranty, it was one of the reasons I bought the Scooby. Will I have to kiss goodbye to that? OR will the dealer be none the wiser. I have read elsewhere Dave Power quoting that noone could tell the difference, but when they service it, or if it blows up, presumably there's no way of hiding the truth.

3. Am I right in understanding that the performance gains are not necessarily squeezing more from an engine that was designed to produce less. But instead, that the UK cars are set-up somewhat poorly simply to get through the UK emissions, and that a PE ecu simply has settings similar top what they should be? PLUS ofcourse the fact that they're tailored settings to suit each individual car?

4. What happens to the old ECU? is it removed and replaced with the new one, or is it modifed to make the new one?

5. How does it compare to the Prodrive conversion? I would hate to go the Prodrive way, simply because it's massively overpriced, and PE's reputation implies a much better product. But obvioulsy the warranty issue raises it's ugly head.

6. Perhaps the most important thing is whether I will need to change the exhaust, because I really don't want to, but if the gains are going to be tempered then maybe I'll have no choice?

If anyone can answer any of these questions, I will be very grateful.

Thanks in advance

Imran

Good questions Imran. I would be interested to know the answers too. Mine is a 94 WRX which I think, could benefit from a PE stage 1.

Imran,

I had the PEng Phase I sorted about 18k miles ago now - magic. In answer to your No. 4, I believe the standard ECU unit stays in place and a piggyback board is used to gain entry to the programming and removed following re-programming.

I am interested to find out what other mods Dave would recommend to complement the Phase I. I had the Aquamist water injection fitted with an optional add-on water bottle but am more interested in comments on uprated clutch/brakes and the suchlike.

1/ Don't know the answer to this one, can only say my car did not run very well with normal UL but soon as SUL went back in the tank the car was like a rocket again . No reset required.

2/ I have had my phase 1 for some time now and my dealer has no ideal that I have it. If you saw the list of extras that I have on my car you would see there is no warranty left for me. But my dealer still does all work under warranty. If my car was to blow up as you say I would have the phase 1 conversion removed and then make a claim.

3/ The UK car are set up very rich and a lot of fuel must just be wasted. I do not know a lot about remaping a car's ECU but from what PE say this involves a lot of work. I can say that I get another 20 miles to the tank of fuel as well as having the extra bhp and torque (see previous mail for figs.)

4/ The ECU is modified by having a piggyback board fitted.

5/ I have had the Prodrive conversion on my MY98 and It did nothing. I think you will be hard pressed to find anybody who has had anywhere near the gains Prodrive have quoted for the MY98. I have had my money back from Prodrive and spent it on the Phase 1 conversion, filter, exhaust. centre pod with gauges, Front & rear spoilers and so on £2000 goes a long way.
You cannot compare the Prodrive with the PE at the moment, The Prodrive is for MY99 as the MY98 Prodrive does not work. PE is for the MY98 as they have not done a conversion for the MY99 yet.

My STi4 got the Phase 1 treatment a couple of weeks ago. I'm now getting over 300lb/ft torque and much improved driveability. Overall I'm pleased with the upgrade so far, although it's early days yet (experience having taught me that the disadvantages of modifications often take time to become apparent).

A few points to add to what has already been said:

Fuel consumption - I've been driving gently all this week, to see what I can get. I'm well on my way to a 300 mile tank, which I've never managed before. Previous best efforts were around the 270 mark. Pressing on I'm getting around 19mpg (sorry about the inconsistent units of measure, but these are the only figures I can remember off the top) which is about what I used to get before the upgrade.

Induction/exhaust changes - get these all out of the way before fitting the Phase 1, because if you don't you'll want to get it remapped afterwards. Presumably this costs money, although I haven't found out from P.E. exactly how much.

Possum LINK - could be a viable alternative, but you'd want a real expert to do the mapping. I certainly wouldn't just download a map and sling it in there, given how much difference there appears to be between cars. David Power spends quite a few hours doing the mapping, so presumably the same level of attention is required if you use the LINK.

Also, watch out that the LINK has the full set of "support" functions that the OE ECU has. They had a 22B with a race-spec ECU in at PE the day I was there. Aircon didn't work and it was undriveable when cold because the ECU had no concept of choke. I'm not saying the LINK would have these exact problems, but there might be others lurking. By remapping the original unit you sidestep the whole issue. OTOH if you go the LINK route then you still have your untouched original unit to stick back in there at sale time or if your engine goes pop.

In regards to the LINK , the unit comes with the WRX module although tuning it can be done quite easily with the tuning tools:

Tuning LINK
Knock Link- Detonation Sensor
Lambda LINK
Intercept LINK
AFM - Airflow Meter

I do agree that most of the people upgrading would require a more hands on approach with the tuning side of the ECU.
Although if you do decide to purchase the above items or some of them, you can quite easily maintain a perfect air/fuel ratio with every modification you undertake.

BPM, Greg you should already know that the Link ecu does not use the Air flow meter at all. In fact once the Link is fitted you can completely remove it.

Anyone considering this route needs the ECU (comes with a default PROGRAM and SETTINGS built in that need adjusting to suit every car.

You need more than a "hands on approach", you need to understand how engine management works and how the different functions interact together. Its not a job for just anyone and could be a very destructive upgrade if carried out incorrectly.

They need the TUNING MODULE that is needed to adjust the ecu settings (without it you can do nothing)so that the car performs at optimum.

They need the SERIAL LINK to datalog and record the ecu parameters and to determine where and by how much (if at all) the engine is knocking.

Its a very effective upgrade for those with the right knowledge and experience. For those without I recommend the PE upgrade route which is also excellant.


Please try and be accurate with your postings, its in your best interest.

Bob

Question

PE - When U said that U went to Japan... I was wondering which tunning company there did U go to. You were saying that U are there to show them on how to remap the Subaru ECU.

As far as I know... when comes to Remap ECU with Japanese Car.... they are very advance. After all they get the car first before Us.

Could it be Mines..Prova..Bozz Speed..STi ..PSI ... will I see U in Japan on Oct./Nov. for the Tokyo motorshow??

Very interesting work that U have done with the Subaru ECU. Hope to meet U one day.. Japan or UK.

Might learn something from U.

Mr. Power you said that the Japanese tuning companies are not very advanced when it comes to re-mapping ecu's but they seem to be able to do a fine job with their cars, they may have different objectives when they tune up their cars(i.e max. power), but that doesn't mean they're not good at it. It suits their application just fine and that would make them good don't you think? I'm sure if you were to tell them to tune the ecu for reliability and not just all out power they would be more than capable of doing so, if they are after all able remap the ecu to more complicated levels where the turbo, injectors and cams have been changed. Like it was said they did after all come up with the car in the first place. And if they can re-map the ecu simply by post without even having to have a look at the car, they must know it quite well and be quite good at what they do. I live in Malaysia and I sent my ecu to Japan for re-mapping and they have done an excellent job so far. My car is used everyday, I don't have an upgraded turbo, cams or additional injectors, fuel consumption has remained the same and I have not encountered any problems so far. But I guess part of the credit must go to my local mechanic here too I guess

Interesting. All the company that I have listed are big and they have good team of people working under them. They are very well organize and giving good results too. Even with their Mail Order service.

The most important things is that the enginebuilder are able to give all the important information on engine mods. and specific area which need to be remap on the ECU. You need to know inside out of the car.

Are U working alone ..... doing all the remap alone?? What difference are there between U and them then... those backroom boy. You still need to goto Japan too investigate?? This happen in UK too. 2 to 3 years experiance with Subaru Map Address ... is call an Expert?? We are all learner and is not right to take all the credit to ourself.

Learn like U are going to live forever. Thanks to you all ..... cheers.:-)

If you read carefully what David P said!! There are a small number of ECU re-programmers in Japan, that the tuning companies send their ECU's too, which to me says they dont know how to do it, but they do know a man who can. Therefore if you have sent an ECU mail order, does the company you sent it to, remap it, or do they then send it to someone else. Davis also said it was a huge generalisation.

Greg, the post was not intended to "flame", merely to clarify. You were at the dyno day on the 14th. I have a Link ecu which I ran on the dyno, the results are on Paul Strongs site. The product is excellent and I have had loads of email about it. It is, however, important that the non-technically minded person appreciates that the setup is not simple. Anyone doing it for the first time will need support in order to ensure that they do not damage their engine..

Greg,

I think the other point Bob was making,was that you listed 5 'tuning tools', of which only one is of any use to a Subaru owner,and don't mention the 'serial Link', which is.It would be almost impossible to set the car up without the tuning Link,even with the default map,which is designed for a standard turbo, and needs some adjustment for STi's etc'.

The product is fantastic(in the right hands)and it's sad that the way you 'market' it is putting people off.That's why I got mine,direct from NZ.

Mark.

Okay point taken , the point is some people are okay at tuning the LINK and 90% would rather leave it to the experts.I never have indicated that it a simple upgrade since the whole premise in purchasing the LINK it have the correct air/fuel ration after every component upgrade.
Hence you will find our pricing to be almost exact as if you ordered it from NZ. We work hand in hand with Possum Bourne so we can pass on the same pricing.

Most end users would rather drive their car to their engineer and have the LINk configured and drive out. that is what we are aiming for.

I am glad we can start moving to decent debates since I think people can learn a lot from people like yourselves who have, a more hands on approach to tuning components.

In response to Jonathan

The 99-00 will be fine with the LINK although I would like to query a point that I have not understood in the UK.

I. The PE Re-Map, is that merely a chip that has been slotted into the free cocket on the main ECU board???

II. Is the Subaru ECU remapped without inserting chip in the socket?

III. Are the problems with the PE Re-Map for the Sti5 and the MY99-00 because the ECU has no socket on the ECU spare?

IV. If so, it appears that it is not a remap but rather a chip upgrade?

Please correct me since a re-map is considered differently in South Asia, Asia etc.

I might have my wires crossed but I would like to understand what you guys consider "re-map" and what you consider "piggyback upgrade"

"As to not being accurate."

I tried to sum it up for the people on the SIDC, if would like a complex post I get flamed because I promote product too much.
I still know the LINK is the most cost effective ECU option with the Motec being my choice if is price is no consideration.
It allows with the tuning print , serial and tuning link to get the desired result.
This was the system utlised on the AVO Sti that is featured all over the net.
The car drives beatifully, idles perfectly and is a street and track weapon.
The flames are getting a bit boring, I have toned down so I would appreciate some feedback that is constructive that can lead to meaningfull discussions.
