Hi.
I`m having some problems getting accel fuel correct on one engine i`m doing right now.
All other engines I have done with Link ecu, have all been working fine. But for some reason I can not get this engine to be smooth during the initial 0-whatever tps.
It will always cough during the first movement. it`s actually so bad that looking at logs after reving out one gear and shifting to the next fast. the rpm will bounce a little indicating a engine missfire.
With the setting I found to be the closest, it will go momentary a little lean, but quite rich a short time after.
The best settings I have found seems to be a extremely high sens ( 100 ) , with about 100-150% accel fuel ( in total from 0% tps ) and a really fast decay.
Think some of the reason for this is the nature of the engine ( higly tuned 4 cyl 2.0L turbo with quite a lot of cam overlap( mostly from a retarded exhaust cam ) , large 3.5" TB
So 2 questions:
Can someone ( link rep? ) give a better explanation on how the accel sens works? like how the math behind it works.
Anyone have had this problem before, and have some settings that will work with a engine that had a lot of turbulence?
