detonation problem
 

Hi all wondering if someone could help me with a few problems i am having with my imported MY95 wrx version 2 sti i have had the car for about 3 years i have covered about 40,000 miles no problems at all. when i first got the car it was a low milage 38,000 totally minted standard example, i heard all the horror story`s about the imports going pop so after a few mods being fse motorsport fuel pump, blitz ner spec r exhaust, howard and scott de-cat down pipe, blitz iduction kit, arc dump valve. I got dastech to fit and map a unichip! after that was done it was running 1.35 bar of boost and appeared to be running really well! having had all this on my car for over a year i was looking for a bit more power so i fitted a pace front mounted intercooler and radiator kit and fitted a cold air intake up to my induction kit and made a sheild between my engine and induction kit! my next purchase was a hks a/f knock amp which picks up high level of detonation breifly when on full throttle and when i change gear. i have even fitted a blitz boost controller and have turned the boost down to stock level and it still pick up the detonation!http://bbs.scoobynet.co.uk/images/icons/icon9.gif
Any idea`s anyone

Have you added octane booster to your fuel and what fuel do you run?

Tony:D

i run optimax and had it mapped with optimax and have recently started adding millers octaine booster but still the same!

you need to remap the unichip for the new modifications.

have tryed to get that done but to cut a long story short my car was there for a whole day picked it up after an expensive day out in edinburgh and in wasnt re-mapped! is it possable that the frount mount being fitted could cause my problem`s to the map as i have been told that you could fit this to the car and if anything it is making it safer

probably you mounted an induction kit which disturb's the airflow seen by the MAF sensor. I do believe that seeing wrong airflow by the MAF sensor can cause bad timing. Drive closed loop untill it's remapped for safety

nice one if that`s the case i think i will have to look at ripping that uni-chip out and look at another chip or ecu!how is the apexi power fc rated?

Lots of people on here me included use them and rate them highly.Depending on whereabouts in the country you are you have
