recently purchased a 90 S2, know it has stage 3 head, piper cam, race clutch, new garrett turbo(think standard t3) but not sure what else, previous owner mentioned uprated ecu but had no evidence.

Was having a good look round today, took ecu apart, and chip had motorola logo on, so thinking it not chipped?? On closer inspecton I came across a bleed valve!! (which Id rather not have) does this mean that the ecu has must have been uprated/chipped to compensate higher boost??

I dont currently have boost gauge, so dont know what running at, but will get one asap.

Other question is, If its not chipped, and i buy a chipped ECU, can I just plug it in and use, or does it have to be set up on rollers??

sorry if these are daft questions, newbie alert, please....be gentle

 

theres no problem with a bleed valve!!all that engine work with a std ecu sounds fishy!if u fit a chipped ECU in the ideal world,yeah should be RR'd,many dont tho

 

what do you mean sounds fishy?? is it possible to uprate ecu with chip with motorola logo on it???

I hae folder full of receipts, for everything mentioned above, but camt find anything relating to ecu

 

its not hard to get reciepts for an engine,im sure motarolla is a std non chipped ecu,just seems strange its a std ecu on that spec,might be 100% true!!just sayin what im thinkin,lol

 

what the maximum boost u can run on a standard s2 ecu guys ...im running 10 psi ..havent got a clue if mine is uprated

 

as far as im aware m8 90 spec is 10 - 10.5psi, just what ive read tho, im far from an expert, someon else will probably tell you better

 

any one???

 

i think std its 8or10 not 100% though

 

Bleed valves are sweet mate aslong as they set up by a tuner as your fueling has to be matched to your boost level, just had my 90 spec s2 set up by TURBOPACS Durham on their RR, running beutifully at 15psi (using a bleed valve). Give them a shout, found the guys very friendly and willing to have a good chat bowt shit, they seem to kna their stuff

 

If you dont mind me asking mate, how much did that cost you?? Im not far away in peterlee. I have heard a few bad reports about them from scooby owners tho??

 

Cost me £140 mate. Money well spentmotor shifts now lol

 

10psi max on std ecu

 

ok mine must be standard then

 

10.5 is the most the ecu will allow if not chipped!!

 

wooo, I got something right!!! ha ha

just ordered a turbosmart supersonic, anyone got one?? are they as good as people say?

 

10psi max you know if its chipped if you open the bleed valve it wont let you an will pop and bang!

 

hmmmmm, wouldnt really fancy that, dont like the sound of an engine going pop and bang, think ill just see what the boost gauge says when I get one

 

Wise man

 

boost gauge came this morning, fitted it and if its right, the boost goes to 15/16PSi so I guess it is chipped somehow, but when I opened the ecu, the chip has a motorolla logo on it, very strange

Any Ideas??

 

no one??

 

If the motorolla has had a the software reflashed then the boost limiter (which is all a chip is basically) may have been removed. Before you buy a boost valve, try and go in a car with an electronic boost controller, cost around thr £100 mark but gives you much more power to play with, not a bigger bhp figure, but more revs to play with
