Adam: Do you have a setup you have found to work good on a similar setup?

I have thought about doing a alpha-n map with map comp if I can`T get this right. Should at least fix some of the issues i`m having. But thats last resort....

Hi. Idle map is at about -20kpa, and driving can be as low as -50kpa at light loads. Initial jump is to 100kpa. ( large turbo that needs some spool time ) injectors is ID2000 in "stock" location. Intake manifold is a medium runner large plenum and really cant see charge robbing beeing a issue, since fuel would then have about 20cm reverse flow just to get to the plenum Injector timing is the normal 320-380 degrees end inj. Cop in full seq inj\ign Do you have a example setup for a large TB, large cam small displacement where you found it to be working good Adam?

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?
