aldo56 0 Posted August 22, 2006 Ive recently completed my 1.6-1.9 convo I finaly got my afm and ecu in today and its running great. The only problem i have however is: cruising along in 5th at 30ish mph, when you put ure foot to the floore very little happens, it seems to go into a flat spot and the engine doesnt seem to like it. i think it also happens in other gears at low speeds however if you apply the throttle gradualy this doesnt happen. surely this cant be right??? ive also got a piper x filter and the ecu has been chipped. ive tried playing about with the screw on the throttle body but im not sure if this only affects the idle speed and not the fuel/ air mixture?? any possible soultions would be great!!!! cheers allan Share this post Link to post Share on other sites
veloce200 3 Posted August 22, 2006 so difficult to make any assessment without being in the car - could be an airleak or also check the distributor vacuum pipe for leak free condition. Any 1.9 should have good throttle response in virtually any gear any speed. if you are in doubt it might be easier to spend an hour on a rolling road to see what the mixture is doing.

Jonmurgie 2 Posted August 22, 2006 Have you set the timing up correclty for full throttle? Share this post Link to post Share on other sites
veloce200 3 Posted August 22, 2006 ive tried playing about with the screw on the throttle body but im not sure if this only affects the idle speed and not the fuel/ air mixture?? it's an idle air bleed. will impact mixture at other points in rev range as well to a degree.

aldo56 0 Posted August 23, 2006 im going to get the timing set up properly asap, so you think there is an air leak somwhere?? it's an idle air bleed. will impact mixture at other points in rev range as well to a degree. Share this post Link to post Share on other sites
aldo56 0 Posted September 9, 2006 got the timing set up properly now and a new standard ecu in! The car now goes like F**k !!! superchips = rubbish thanks for the advice Share this post Link to post Share on other sites
welshpug 1,627 Posted September 9, 2006 one tip, the engines only doing 1500 rpm in 5th at 30mph... no wonder it doesnt pull! Share this post Link to post Share on other sites
PumaRacing 1 Posted September 9, 2006 surely this cant be right??? ive also got a piper x filter and the ecu has been chipped. Hmmmm. If you put both of these back to standard items it'll probably sort out most of your problems. Share this post Link to post Share on other sites
