Can anyone give me a good explanation of Inj Vs Accel TPS and what this does and how it should be adjusted.

Also can someone give me a good explanation of how acceleration enrichment "decay's" the enrichment value. The manual says its previous amount-decay=fuel addition. It seems like decay should stand for some time of ramp down of fuel. Plus why would 1000 rpm even have a decay time if that was the case. I have played with this function quite a bit but nothing I can see tells me how the decay actually works.

Thanks

fritts, I have been working to understand these two settings for a while now. Though most explanations I have seen are pretty bad, i have gleaned the following.

Acceleration Enrichment - Attempts to prevent lean conditions on rapid throttle opening. I have attached a couple of pictures I have been using to understand this.

Inj vs Accell TPS1 - This seems very similar to acceleration enrichment, except there are only two parameters to control: acceleration and enrichment.
Acceleration appears to be the change in TPS1 voltage WRT time. The enrichment looks like a multiplier (just like everything else in fuel settings). Unfortunately, the values are reported in raw format. Download FCTune and put your .dat file in. It will interpret the raw values for you. Perhaps this one allows for decelleration enleanment (is that a word?). I saw FastHatch mention it one time.

I also found a toyota guy describing these a little differently.

This really sucks that we have to guess as to what these parameters mean. Perhaps someone on the datalogit yahoo group can go ask for a straight answer.
