Sooo, who can tell me what the standard ECU is ? Did a little investigating today, pulled up the carpet removed the kick plate, and the one I saw in my car(which was bought used) has a nice big U8 on it, is this stock? if so, what's a good option to go with for something that can be mapped? I have a friend who's into it and has a buddy who'll map me up for cheap or free lol, and I know that the classic ECU's weren't open source so he can't do anything with it as is, been lookin around and damn ECU replacements are EXPENSIVE lol

 

U8 is a standard ecu for a 92-early 94 wrx running 240ps.
The cheapest option for it would be the ESL daughterboard (£500+ yes i know not that cheap )

The Z4 and 6K ecu (both standard ecus) are relatively good replacements but once again not mappable

 

Model and year of your car will help someone help you!

 

Lol, 1993 WRX saloon

 

As above,the ESL live is a smart bit of kit. Supplied and mapped will set you back £550+vat,and it's an idea to get the later map sensor fitted (£60+vat)at the same time,as it will let you run more than 1.1 bar.
I had this fitted a couple months back,with larger 440cc injectors(£100 ish),running 1.35bar,worth every penny!!

I have been thinking about the same thing with my 93 wrx, I pulled the carpet back and found a U8 ece and a super chips abc box, from what i know that just lets you run more boost by by giving the ecu false readings. Was thinking of going down the Z4 ecu road.
Does anyone know what sort of power i would look to make if i did run a Z4 ecu, I have got a 3" turbo back exhaust, 57i kit and just about to fit a sti tmic and make a propper shield to make the 57i cold air fed.

 

Remove the superchip.
The z4 is a good standard ecu but if you've modded the car then a remappable solution is better.
I would expect the z4 and your mods to make a few more bhp possibly 5-10bhp depending on the health of the car but the only way to find out is getting it to a rolling road.

 

Yes SnazzyJoe, not only is the ESL daughterboard the cheapest way for a v.1/2 to become mappable but - because its part of the 92-96 OEM ECU - it retains all of the OEM I/O signals and features, which Subaru spent millions on developing and is regarded as a quality ECU in its own right.

A great upshot of this is that the ESL board retains the OEM IAM (ignition advance multiplier) anti-knock technology - to prevent detonation. So, if you get it mapped by a reputable mapper on your favoured fuel, not only should it not det anyway, you still have the peace of mind 'safety net' of the IAM feature still present anyway! How good is that?!

 

Sounds pretty good Joz XD Now....how am I going to get one >.< Got a kid on the way and the wife won't let me spend too much hahaha

 

Easiest and cheapest would be www.jollygreenmonster.co.uk - £525 supplied, fitted and mapped! ... PLUS he'll come to you! . You'll have to pay Simon his fuel costs though, so best to drop him a line and see when he's next in your neck of the woods... (he travels the country mapping his head off, lol )

All you have to do is follow his instructions and drive, whilst he maps away on his laptop - you'll love it!

 

Lol, I'm sure. Problem is with a kid on the way and a wife who hates me spending money on the car lol, 525 is steep. Had someone mention to me a ScoobyECU though, what wuld you think of that?

 

ScoobyECU is the trade name of a non-mappable chip/socket to fit in v.1/2 ECUs. It's effectively a non-mappable version of the ESL product, but comprises of just a chip/socket soldered to the OEM ECU's internals.

The map is at 1.1bar max boost and is designed around the TD05H turbo (92-96 saloons) and supporting mods upto decat d/p, full system and air filter. Scott T. sells these chips for £195 - see here: Products. Or if you send him your ECU, he'll fit the chip/socket for an added £50 (or he can supply an ECU with chip/socket fitted for an added £80 instead).

Remember though, it is NON-mappable!

And yes, prior to getting a Apexi PFC, I did indeed have a PP'd ECU and it was great - turbo doesn't run out of puff at mid-high end and pulls all the way to the redline...

 

I had the polar performance plug and play chip in my RA before the ESL Live. It did it's job well,but as said,is a bit limited as it can't be mapped. If your after a cheap power increase,their great,ran mine with no problems. It will also be mapped for uk fuel,and de-limit the car,so worth it for this alone! I only changed mine as wanted to run higher boost,with bigger injectors,headers etc.

Yes SnazzyJoe, I followed a similar (PFC instead of ESL Live) route as mit.

FTR, Scott told me that the ScoobyECU map is based around Esso Supreme SUL 97 RON (but any 97+ RON will do). That said, I've heard many a disgruntled voice on here regarding BP Ultimate 97

 

SnazzyJoe, I think I may have come to your aid, lol... There appears to be one available on here (already in the ECU, so a simple 'plug 'n' play' swap-over)!!!...

PM the chap and/or post on his thread ...

 

How much does JGM charge for a remap for the esl?

 

Don't know for sure as he doesn't list it as a separate menu item, but expect it to be very similar to a PFC (maybe a little less). If so, then you're talking <£293.75 (£250 + VAT).

Then minor tweaks to his own full remap would prob be in the region of <£150.

Send him a personal email to ask - he nearly always responds within 24h, and sometimes almost immediately!

 

ESL Live map interface is the product to use if you are looking to retain the standard ECU functionality with potential to map beyond 1.1bar, injector, turbo and MAF upgrades.
440's and a later Map sensor will have you running 1.3. Upto 1.4 if run with uprated pump/reg and intercooler, although some intake combination pull in a bit more air which can not only max out the 440's but also the MAF at 1.4bar.

 

Hi Scott,does that mean for me to run more boost than 1.35bar, i'd have to fit a fmic? I have a sti 6 tmic at the mo.See my profile for spec.

Thanks,Mit

 

An STi 6 TMIC is OK at 1.35/1.4 (ish) but may need to think about some sort of intercooler waterspray if sustained heavy use is required, and there's more to think about then the TMIC/FMIC if you want to go beyond this. A larger turbo running less boost for example, fuelling and the strength of the block.

Although at the price of FMIC these days their great value for money.

 

Thanks,i've been looking into the TD05-18G route,would this give similar performance,for less boost?

 

if this helps joe i have a my96 wrx with the z4 standard all apart from haywood scott decat and rear box this produced 227 at the wheels on a rolling road
