Hi all,
Ive just picked up an import version 3 sti, with decat, and air filter. I was told it was standard apart from that, so should it run 1.3 bar boost and drop off slightly??
I have owned wrx before, and they boost cut really easlily, does this seem normal???
Thanks for the help guys

 

standard boost is 0.9 bar pal.

 

 

Finally a chance to pull carpet out and look at ECU, well that was a surprise. I have a Zero sports racing developments ecu!!!
Anyone know about these?

 

I thought the STI was 1.1bar?

 

Dunno, first sti. Previous cars all been Import wrx`s. Ive definately got a Zero sports ecu, but I was looking at going simtek, but if I can, id prefer to just remap Zero..........
Got to watch the pennies

 

Zero sports = octane booster needed

 

Octane booster aint worth sh!te, proven in various tests to be a complete waste of money. Some push octane by as little 0.1 points.

 

2nd that Booster , lots of it, , honest, fill it with V - Power and take it to a dyno, get the det cans on it and do a power run with AFR check. then u have no worries, MINES and all Jap ECU's can be mild to wild. Just get it checked out.

 

dead on, away and research NF Octane Booster. also, he NEEDS octane booster if he wants to run that ECU as its designed for Jap fuel ie 100RON

 

Agree the zerosports usually very agressive on timing.

Get it checked.

Re: Octane Booster - if you want to waste your money on booster everytime you fill up then go ahead. The result is an unknown increase some by as little as 0.1 ron. You still won't know if the engine is safe under load.

Waste of time, waste of money, and you end up in the same position as before.

 

Thanks guys, I need to sort a dyno run with a good tuner so that we can work out an action plan. Any suggestions fairly local to Hemel Hempstead in hertfordshire???? Or, I would be willing to travel if a good guy suggested

 

He's waving :wave: lol

Junction 11 of m25 close enough?

Simon

 

Probably yes lol. Have looked at your stuff fella and very intertested in letting you tinker!

 

Jolly are these Zero ecu mappable or just a preset tune? Fancied going Simtek but need to save some money as missus due in Jan. Unless, I dont tell her...hahaha

 

zerosports ecu not mappable no

 

nooooooooooo. Ok, well ill have to have a little save then. would love to get near 340, but would I need to change ecu for that?
