After running my car on the rolling road at PE in January and only getting 234bhp with a full decat and induction kit I investigated why the figure was low. As we now all know the ae802 green sticker ecu is to blame for this, however could I find an earlier ecu for sale for decent money, even Grade A now have a waiting list.
From this forum I discovered a company called Ecutek, run by some well established gents. They will re-program your Ecu to an earlier version for £150, I booked my car in for Saturday, as Ecutek share offices at PE i also booked a rolling road session to ensure my money was well spent.
On my first power run a laptop was used to log data direct from the Ecu, capturing more than I could understand. My car hit 236bhp, Stephen went through everything with me, pointing out a lean spot at low revs due to my induction kit. His next step was to re-program my Ecu with his version of a AE800 MY99 Ecu. My next power run got 268bhp with a really impressive flat torque line. This was without changing any fueling / boost, how impressed was I.....
Driving the car home was a different story, its always needed to be wound up to fly, not any more, 3rd gear feels like 2nd, I dont need to change down for instant accelaration and response, I was so amazed, I drove like a nutter the 70 miles home, at one point beating my best top speed by 7mph, without even knowing I was going so fast, this was without trying, well I did have an MR2 behind me at one point !!!!
This morning from cold I got no hesitation/surging at all.

Anyone interested I have the data log from my car in .csv format, you can see I am running standard boost / fuelling etc, I also have printouts from the rollers showing the differences. I was pleased to see my car advances the timing by .5, Optimax must make a difference !

A big thanks to Stephen of www.ecutek.co.uk and to David Power of Power Engineering who sell this product. They do a mail order sevice as well, they will send you an pre-programmed Ecu, you then send back you original Ecu.

I am at Bolney if anyone wants a ride to see the difference.

Nice one

I had my MY98 with D-Cat exhaust and ITG filter (the only power mods) on the rolling road last week at PE and got 269bhp (1bhp makes a lot of difference ) How happy was I

I was offered an STI ecu with a PE piggy back chip which Merve reckoned would give about 280bhp but with much better torque...very tempting!

May try a Dawes first

Phil - I tried that ECU Merve offered you when I went to PE, turned my 256BHP (MY98 with decat centre, SS back box, ITG filter, Optimax) to 284!!!!

How do you get 54 BHP over standard out of a MY98 with just a decat and filter?

Philip Attaway

ooh, maybe I'd get more with the downpipe

Phil

Jeff Wiltshire

The obvious question is...

If Subaru made such a good job on the MY99 ECU why did they do such a bad job on the MY00 ? am I missing something here ?

I have to say b**ls**t power figures I am afraid. You don't make that much power at 0.9 bar on a MY98. I think that defies possibility on your turbo at that boost! Sorry. Oh I love rolling roads. I know PE are optimistic but frankly that figure takes the biscuit. Good for the pub though.

john banks

Who knows which (if any) rolling road is right and I don't want to get into that debate!

Let's just say they all look quite high figures for the number of mods done, many PPP decats running over 280 bhp for example, yeh right, I really wish my car was over 280bhp. It probably would be on this RR but I don't believe it.

In context with the rest of those figures your car puts in a good result, but it is not unbelievable. I suppose it is the same old story only compare with cars of the same drivetrain/gearbox on the same rollers on the same day with the same operator at the same temperature and even then it will be inaccurate.

Also of note a lot of the torque figures are considerably lower than power figures, but we all know PPP cars produce a lot more torque than power. Perhaps the torque figures are more realistic (slightly).

Here are some quotes from acurrent thread in drivetrain. Did you get out of the wrong side of bed today

Phil

john banks

No I am just argumentative. But I don't believe 280+ bhp out of a PPP with decat. If people take offence by anything written on this board debating a few technical issues they shouldn't.

john banks

PE underestimated LOL! Do you have the thread?

Philip Attaway

being serious John, I fully respect what you are saying.

The result was a lot (well 20bhp) more than I might have expected for the mods carried out but there was also an Elise run that day which did 'exactly what it says on the tin'

Who knows, but next time i'm in the pub...mine's a JD

Phil

polarbearit

Sorry John, half asleep... Edited to correct

john banks

I wish our rolling road read higher then I might convert my numbers a bit higher. Compared with those above 257bhp does not do it justice. I reckon 280bhp at PE. My car is wildly quicker than a plain decat car, but they show a higher figure!

One week apart, similar weather conditions:

Tuning Japanese: 340bhp

Power Engineering (following week): Second run 356bhp; Third run (inisted by Trout) 354bhp

Getting back to the original point - the 'green?' ECU on MY00 - I have a MY00 and would like to find out what I have, is it easy to get at it to look?

I am NOT about to invalidate my lovely, expensive warranty for the sake of a re-mapped ECU - but at the end of the warranty period, who knows??

Pete

simon_prickett

I think the thing with the rolling road is not to take the figures as gospel, but to do a run before you change something then do another at the same place afterwards.

At least then you can see what the difference is percentage wise.

So in my case from the graphs on www.crudworks.org you can see the difference the PE ECU makes, rather than definately say it gave my car 284BHP with the standard downpipe.

Don't want to get into a mudslinging match, so I agree with John that the figures themselves may be a little out, but as long as a number of runs are out by a comparable margin the results should be comparable with each other if you see what I mean?

Simon.

Pete

Yes it's easy.

In the passenger foot well, undo the two carpet screws at the front end, pull back the carpet as far as you can and you'll see the ecu cover. There are four bolts holding the cover in place which can be undone with a (10mm?) socket.

Remove the cover and you can see your ecu complete with label.

No unplugging of ECU or any electrics is required.

Maybe the figures are high. who knows, I dont think so, thats why I had the before and after runs as a comparision, 34bhp difference.
As for warranty, well its still in place, running a Subaru Ecu with a Subaru map.......
Why bother with a Link now !!!!

P.S tried em both as well...

Hmmm, I'm running an AE801 map now and although I've not RR'd it yet, it certainly doesn't feel like a 30+bhp gain!

The car does run better and feel better, but not to the extent of your RR figures suggest.

If your figures show a real comparitive before and after run, then I'd say you had a tad more than just a 801 map. More like a PPP or even a link.

£150 sound tempting if true.....

Just ordered mine; will report back once it's in.

LitchfieldImports

Why don't you pop it down to Powerstation, I've always trusted there figures. Just had one of our cars run the other day, Manufacturer claimed 400PS and it made 395BHP

Iain

STi wanna Subaru

iTrader: (1)

Ok, I'm probably going to look stupid here but I'll ask anyway.

You say they re-mapped your MY00 ECU with the map from a MY99 ECU. Does this mean they could have re-mapped your ECU with the map from a PPP ECU?

Floyd

iTrader: (9)

I guess so, but that would be against copywrite. But so is copying the 801, I think.

JMHO.
F

Tal

yes a ppp map or similar would appeal to me as our md had a MY99 and when mine and his where standard they were identical on performance we tried many times and thoughts ??

Tal

lordlucan

Stephen Done of EcuTek has developed a similar map to the PPP that can be customised for your mods, I believe the PPP has a tendancy to run lean, give Ecutek a call.... WWW.ECUTEK.CO.UK.

I am happy with my re-map, give it a few months and I may be back to see Stephen as he showed me what he can do....Thats once I have got used to the power !!

Just ordered mine with Dave Power @ ECUTEK..

informative and helpful people, should be with me tomorrow, DeltaECU Tek 1, which aparently is 801 mapped + optimised onto an 802 chip (depending whats in stock!).... can't wait, likewise, will report!

rob

mattski2

Rob,

Do you have to give them your old ECU?

ta,
Matt.

Is this not normal then? It was a mighty cold day which probably had a lot to do with it. PE didn't say anything was up with the fuelling etc.

Here is my graph


Phil

Edited to say that the car is running at 0.9 bar...according to the defi guage.

Philip Attaway

well i'm not in the pub

It was my first run so have nothing to compare it too, other than it was in the middle of the runs held that day and other respected cars ie. Trout's and Moe's were also run. They must be bull**** pub talk too!?
