Yeah you'd probably have to add fuel, but it'll depend on RPM, the acceleration enrichment feature is like an accelerator pump, its both a quantity and duration of fuel.. so adding more will add more fuel, but also for a longer duration, that is what smooths out the stumble..

 

Ohh thanks alot for breaking it down for me- this is the last thing i need to get full driveability back with bigger injectors- thanks!

 

This thread is great guys.



Edit. I'm assuming higher voltage = leaner right? I may have missed that part somewhere

 

Damn that the reason why I always had the problem of my car running real rich as I stepped on the gas. My was set at 1.98 all the way down. It would go rich the moment i stepped on the gas. Thans Guys

 

Mine was set at 1.98 all the way down as well. My injectors we're scaled with my last flash... I have no scaled the injectors so this leads me to think my Accel Enrichment needs adjusted... any thoughts on this?

 

Old thread I know but I got a question.

Can I mess up my car if I tweak the accel enrichment tables inappropiately?

I've got a bad lean condition upon first going WOT...it lasts "way too long" and its causing drivability problems on the street. Once the afrs come down to 11.0 all is good but more often than not I'm coming off the throttle at that point. This happens even at high revs where spool is super fast, so its a separate issue from spool time.

I hope I'm not expecting too much out of the car. I know a little bit of fuel delivery lag is unavoidable. I expect once you hit full boost the afrs should be going good and I don't want to wait further for the fuel delivery to catch up before I get good power.

 

The higher the number, the more accel enrichment you get..

AS far as I can tell, from monitoring the parameter in Evoscan, it will show its "enrichment" for the entire duration your speed is increasing..

Originally I had thought it would spike then taper off, this only happens if you hit the gas and let off, or return to a constant throttle position, but as long as the engine speed or vehicle speed is increasing, it seems to show the value set in the table for the RPM your in..

This probably doesn't show any duration value, but the enrichment value on a throttle or load change, So what this means is, although I think it still works by hitting the amount of fuel you need, and then tapering down when its no longer needed, the value in the logs doesn't appear to change. (AFR's do however)
