please, before i do somthing i regret, if i put a decat down pipe on my '93 WRX, am i going to get a boost spike or fueling problems?i know this question has been asked before, by me and others but i cant find anything about it!!!!! would a scooby ECU from Mr Taylor solve or help if this is an issue.

help is much appreciated

thanks
james

 

Possible fueling problem.. but probably be okay..

Would be wise to think about a Knocklink anyway..
Super Unleaded of Optimax a must..

ScoobyECU would be a good investment as would get a map suitable for UK fuel rather than 100RON Jap fuel.

lovly, thanks alot, ive been running it on super plus octane booster, and knocklink is on the cards, if the knocklink shows im getting problems, what does this mean? does it show your engine has had it or bad fueling etc....

thanks again JGM

 

Knock link shows Knock.. pinking..

Which will kill a turbo engine..

nice, de-cat came this morn, looks chunky lol when i saw, what does this mean RE the knocklink, does this mean im running lean or too lower RON fuel?what im getting at is the knocklink going amber/red saying 'heres a warning your engine is gonna pop' or does it mean, 'theres a problem, IE, fuel, go sort it'? also, seen them on jap inovations for £88 ish, is this all i need or do i need the plug/fitting kit i have seen people post about?

thanks AGAIN lol

 

If the knocklink shows red you are running to lean and/or bad fuel,ie, low RON value. The imediate thing to do is back off quick or, yes, you will cause damage.
Personally speaking i had a de-cat on my 96 WRX and i didnt have any probs whatsoever, but as mentiond, it is a very good idea to get a K.L just to keep an eye on things. 120 odd quid is much cheaper than a blown engine. Just tell them you want the harness, bosch sensor and obviously the 'box' itself.

 

lovly, thanks alot for all your help, seems thers alot to look outfor, well, more than i thought! think i shall be ordering one in the morning,think dawes is on the way too or is cleaning the boost solinoid easy? i have asked this before but had no reply, makes me tihnk it might be risky lol.

let you know the outcome of the decat

cheers a bunch
