acceleration enrichments
 

I am trying to get acceleration enrichments close to what it needs to be before going to the dyno. Does anyone have a rough table for 440cc injectors?

I am using MS1, the diyautotune MS2 turbo map/460cc injectors is the following:

tpsdot/s : 100% = 7.7ms in my case 100%= 5volts/s
300%= 8.7ms =15 v/s
641%= 9.6ms = 30v/s
993%= 10ms = 50v/s

threshold= 75% or 3.75volts (im using automatic 0-5v tps)

Does that look like something you guys would use?

Well I went out for a test session in the highway. Got the AE tuned a little better this is what I came up with:

1.2v = 1.1 leans out just a little bit under slight acceleration but it doesnt stumble and after that it richens it up ~5% under target afr
8.6v=2.2ms
18v=3ms
24.7v=3.4ms

it seems like not a lot but any more than that and the afrs dip into the 10-11s.

My threshold is 1.758

your TPSdot threshold is 1.758? that's too low.

it needs to be above the lowest value you see on the plot as you sit idle.


you current enrichments settings look typical. you just want enough extra fuel that you don't go lean when you hit the throttle.

I'll raise it to 2.5 or so. I'll log a idle session and will go from there. Under slow partial throttle it spikes lean for a millisecond no matter what. Is that normal? I feel like the ms needs a little time to react

yes it's normal. you shouldn't even be able to feel it though.
