Hi all i have a my99 classic and i have decided to go ahead and mod it a little my plans are to try and get about 300-320bhp out of it.

im starting to source parts for this mod and i think i have got my head round it all thanks to all your post on this site.........
The only thing im having trouble getting my head round is once i find and fit all these parts i know it needs remapping but im getting a bit confused which and where due to my99 being an awrkward year to map.

maybe im just not reading right but some advice on this matter would be graet

many thanks in advance

On a 99 its going to have to be ecutek to remap your existing ecu. No other software available at the moment.

Your location says Farnborough? With that location id reccomend jgm and use surrey rolling road

 

Standard ecu mappable with ecutek no issues.

Simon

 

thats good news what sort of cost is that

thanks for the replies

 

you can up the power to around 260bhp without a remap by adding a free flowing filter,decat exhaust and upping the boost level.i have this done to my own my00 turbo and before the engine meldown police say this will end in tears, i had knock detection, afr levels etc checked whilst slowly upping the boost.everything seems ok on the standard ecu at around 1.2 bar.

 

Remap is a definite due to a bigger turbo going on it td05 or a v23 or something like that with full decat panel filter , sti inter cooler walbro fuel pump ect ect
I would like to know is it better to remap the standard ecu or buy another one don't really know difference in cost or performance hence prob gonna remap standard

 

Good luck to ya, but just think how much better your car would perform with a custom map done.

 

To remap your standard ecu you're looking at £550 first time around as you have to pay for a licence

 

good luck? there is no reason that my car will end up with engine damage,as said before all the important stuff was checked whilst slowly upping the boost, i see the guy is wanting 300+ bhp and for that,obviously you cant just chuck bigger turbos etc on without a custom map.my point was you can safely achieve 260-270bhp without a 550 quid map,which on a £1500 car isnt value for money in my opinion,full engines go cheaper.i am not knocking remaps,i will be going down that route myself shortly with a bigger turbo etc but was a good hike in power from a standard car for a starting point.

 

Ok some good advice ty all defiantly gonna go with the map just because of everything I have read I know it's a lot of cash for a not so expensive car but bit once I have done the upgrades I wanna know its all good

 

Wideband AFR, ignition/knock and boost were smooth and just where you'd want them on cruise, part throttle and full throttle across the engine speed range considering the car still had one cat. I don't think it would run better with a custom map. I might have tweaked the timing a degree here and there, but on this car it would have been tinkering for tinkering's sake.

It is surprising what you can do with a bigger turbo and a standard ECU too, although you need to be able to tune to pull it off (ie you need to understand ECUs), you just do it when you don't have flash access to a particular ECU as in this case. Happy to look at it bigbl, keeping the same intake, stock 440cc injectors with that Evo IX fuel pump, you can adjust the global ignition with free open source tools, open loop AFR can be adjusted with an adjustable fuel pressure regulator, and boost control is easy.

369 BHP has been had out of a standard ECU on a WRX before, that was with 380cc injectors and playing around with a 5th injector. 440cc injectors and a fuel pressure rise on a MY00 will get you a long way based on 440cc * 4 cyl / 5.5cc/BHP = 320 BHP, with another 50 BHP for 4 bar fuel pressure if needed.

Gearbox is the biggest issue, finding something this old that will take the torque.

 

"you can adjust the global ignition with free open source tools"

Interesting comment John which?

This is a Jecs ecu remember.

The problem with upping the fuel pressure is that it can screw up all the off boost/light part throttle fueling.

nice to see you posting

cheers

It was part of the SSM protocol for JECS too IIRC. Unless you have tried it and found it not to work, it is there in ROM raider or ECU explorer IIRC.

If there was a modern equivalent to the original NF that gave us 5 degrees then we could easily run a bigger turbo on stock ignition timing without even trying ignition adjustment without mapping means, but I still have some NF in my shed from when it seemed to change to worthless. Do you know of anything contemporary that actually works without needing more injector like methanol?

Different approach as a typical remap exceeds half the cost of some of these cars now.

You wouldn't approve of us putting a bolt into the end of the MAP hose, but it is a lovely smooth method of boost control. I don't think my TD04 could do much over about 1.5 bar anyway even if it tried so there wasn't much to get worried about fuel cutting, and I couldn't measure any difference in fuel or ignition from having the MAP read atmo all the time.

With an induction kit it only got richer than 11.0 after peak power. The occasional 0.5 or 1.0 knock at low RPM just to show it was working. I didn't find an equivalent to IAM in the open source software (it was not in the Ecutek software when I as using it either but think it was added to JECS after it was found in Denso?) but it wasn't knocking on a hot day and running lots of timing.

JECS would have been a nice one to disassemble, 128k would have seemed user friendly.

Different set of problems now the MY99/00 is older, but MAF and third gear always seemed to be the trouble on the UK cars back in the day. Most of these cars will have fallen into the hands of fannies at some point so I would view tuning one with suspicion, but bigbl's example was an absolute steal.

 

As you say John, with the age of the later classics now,little is known about what kind of life the car has had so in that respect, the best ecu mapping can be done alongside a bigger turbo etc, but with 100k under its belt who knows what 300+bhp will do to the engine and gearbox? It's a lucky bag.with the boost upped and the map vac hose disconnected/bunged it drives as nice as the 99 turbo I had ten years ago and a fair wad of cash was put into that one to get the same power we got for a couple of hours tweaking with the boost. Just ordered a td05 front entry so will be interesting how the standard ecu will cope with it.

 

Hi again all just another thought I now have all the parts ready for the modding

Now starting to think more about the ecu I know I can map the standard one on the car already but this will also need the licence

My question is are there any other ecu's from other subarus I can use or is there a certain after market one I can look for second hand that's licenced already

As looking around there are lots of ecu for sale just don't wanna waste time looking if there is not really another option apart from getting licence and map on my standard ecu that's already in car
And I know even if there is another ecu I can get2nd hand it will need mapping anyway

Thanks in advance

 

You need a 99/00 uk ecu with licence already or an after market ecu like Apexi or Alcatek

Simon

 

I have found one of these on eBay that has already been mapped so guess it already has licence it's a E3 tek2 ecu removed from a 1999 Subaru impreza turbo uk would this fit ??

 

And cheers for reply simon still gonna give you a call for the map when I get my head round it all lol just looking at most cost effective way

 

yes e3 will fit.. just have to trust them that it has the licence as no way of telling until laptop is plugged in

 

That's what I thought on trying to prove it the guy still has it on car and it's modded with vf34 fmic ect and he has 100% feed back.

He wants £150 for it does that seem good price

 

Hi again all would a jdm sti 6 type ra ecu fit on a my 99 classic
Many thanks

 

That's not the route to go.

You need to bite the bullet and have YOUR ecu mapped to suit YOUR car.

 

Yeah or you will just waste money buying parts that don't fit or end up buying a mapped Ecu without a license

 

I know I keep telling myself that but not listening lol
Your right time to save up some dosh and just map it got all mods be a shame to half **** it lol
Cheers guys
Just needed someone else to kick me up the ar@@ lol

 

Plus you will need to map that Sti Ecu anyway

 

I've got a Link ecu that's for a my99/00 or v5/6 import

It is a 3 plug ecu but NOT the earlier MY97/98 or V3/4 type.
