Accel enrichment will not activate
I'm working at accelaration enchrichment but I can't get it to activate.
The lowest TPSdot value I put in is 100%, this might be to high, but in the enclosed log you can see that TPS dot has been 186% but it didn't activate AE.
Anyone has an idea why it doesn't?

Re: Accel enrichment will not activate
Because your Accel TPSdot threshold % is 200, you never reached that. I usually set the lowest accel point and the threshold the same value.

What settings do I use? Do I look what TPSdot is when I lightly tip the gas and what it does when I floor it rapidly?
Than use both values as a minium TPSdot and a maximum?

TPSDot should be set just high enough not to trigger accidentally at steady throttle.JelmerS38 wrote:What settings do I use? Do I look what TPSdot is when I lightly tip the gas and what it does when I floor it rapidly?

Re: Accel enrichment will not activate
you can make a log of idle and look at TPSdot and set your threshold% just higher than your tallest bilp and then stab the throttle as fast as you can and that will show your max value so you can set your table a bit higher than that, then pay close attention to what your afr is doing and that will guide you to adjusting the graph, good luck!!
Re: Accel enrichment will not activate
That is what I did and it worked! I'm still working on it but it is getting better and better.
Only thing that I can't get better is when I'm off throttle and gently accelerate again after a turn or speed bump. It still hessitates pretty bad. The huge play in the ring and pinion of the rear axle doesn't help with this either.
Ill make a log of this and post it up.

Re: Accel enrichment will not activate
Post up your modified MSQ or a screenshot of your AE settings. I've found that using some Map blend helps with low throttle Tip in. It's all about finding the sweet spot. Lower your MapDot Threshold as well if you blend. 40 to 50 is fine. TPSDot threshold can go as low as 20.
I also have TPS WOT Curve enabled. Here are some baseline settings that I start off with.

@Blackbird: Thanks! I will try that too.
