.... before i scrap the f*cking thingI put the car on the road 3-4 months ago and straight away i knew there was a problem, basically it didn't go as i had expected, at first i told myself that i just had a high expectation and to just high boost it and be done with it, anyway the more i used it a realised that there was something wrong, i'd use it 1 day and it would seem ok then the next it wont run right, when putting the loud pedal down hard it just bogs down as though there is too much fuel so to to accelerate i have to put the pedal down slowly, then when i hit 4k rpm it stops reving like i've hit a rev limiter
So went the routes of spark plugs im using colder grade (the 1s rich recommends for track/high boost) but rich tells me they are ok and shouldn't cause this problem, i tried the 1s recommended for low boost and still no change.
Then i starting thinking it was over fueling so removed the ECT sensor dropped it in a kettle whilst it was wired to an ohms meter and the resistance is as per right through the range
Lamba was changed when i de-cated
ICV and Map have both been fitted on my other 306 and fine on that (i've fitted the 1s from the other 306 now)
Then i thought rather than it over fueling is there not enough air? so fitted a boost gauge to check boost and its showing 8-10 PSI not sure if this is right but i'd say on a low boost that would be about right
When the car is parked up i can rev the engine cleanly to 7-7.5k RPM but under load it just wont rev, the last time i took it out (about 4-5 weeks ago) everything was working fine and it was such fun to drive, why it worked then and not today i dont know
Also the speedo doesnt register correctly (20mph when doing 4k in 6th) not sure if the map is run through the speed sensor ???? (hopefully it is and thats all i need to change)
other than what i've listed can anyone offer another idea/sensor before i put a sledge to it
