Forget all this version crap, no such thing as a version 7 anyway, it ended with version 6 in 2000, what you can give us is what year the car is and is it a UK or JDM model and are there any modifications to the car?

Tony

ok calm down lol i know wot v7 means and bet you do.,my 02 is better way of saying what car is tho,i agree.

If JDM sti then it is probably taking huge amounts of timing out due to det if it is like any of the other jdm's I have seen.

Could be fuel pump too causing it to run lean - it has the feeling of strangling itself at that sort of revs.

Need checking.

Where are you based?

As it is a JDM it will be mapped for running on better fuel than we get so as said previously the ignition timing with be retarded to reduce det. GET IT MAPPED SOONEST, or you could cause engine damage. If you do get it re-mapped consider a few choice modifications such as exhaust, air filter replacement and uprated fuel pump prior to re-map.

There are serious differences between models, hence why they dropped the versions as its confusing, the fact that this is a JDM car means its running a different map and turbo to a uk car, and as such you should just give the model year and market otherwise its really confusing trying to guess what car is what.

Tony

PS, stick to saying yours is a MY02 UK STI, its easier and it wouldnt be a version 7 anyway

These cars are mapped for 100 ron fuel, you cannot run them on unleaded, that just blows the engine to bits, they need v power or tesco 99 (id go with v power personally) and a remap is recommended (along with a KS3 knock sensor or the likes).

thanks for all responces i do run the car on tesco 99, its got imported in 2002 so i hope its has had a remap for uk fuel by now, dynamix is going to have a look at it for me on friday hopefully it will be sorted soon.

My bets are on either bad plugs, coils or fuel pump on its way out. I wouldn't be driving it on boost until its sorted though or you will kill the engine and have a £2k bill on your hands..

Good to meet you this afternoon James.

Gimme a shout when you have the fuel pump replaced and the pump controller checked.... in the meantime - just keep off boost altogether as it is running severely lean
