Not yet. It is on the TODO list.

I don't know what it is supposed to look like, but I don't see any missing gauges?

It might be best asked in the TunerStudio sub-forum.

James - I have been testing the beta 20 this past weekend. The accel enrichment is much more sensitive and I am working on dialing it in. However, there is one strange behavior. When coming down off of a fast acceleration / high load run there is a huge spike in the injPW (up to 65) that then causes an immediate overrich condition (afr ~9). Is this a bug or something wrong in my settings? It occurs fairly consistantly (when high negative MAPdot and TPSdot).
Thanks,
Sven

msq and datalog attached.

That 65ms looks like a calculation is overflowing. Added it to the TODO list to fix.

ugh. that 65ms spike at throttle lift was there in alpha 18 as well. Ken could never reproduce it.

Sven, do you have any of your MAPdot or TPSdot curve points set at 0 for the dot and 0% for the enrichment? Try that. It helped but didn't eliminate the problem for me.

y8s - I do not. I start with 0% at the dot threshold positive/negative numbers. I could try adding a middle point of 0 dot / 0% in the interim.

What you have should be fine - I already looked at that.

in your "new accel tpsdot curve" you have -1000 tpsdot (%/s)! set this to under -500 tpsdot (%/s)! -499 works by me!

Is it just me or has someone else had cranking problems with these beta codes? I have to open throttle sometimes little bit before engine starts. With same settings in 1.0.5 cranking works very well.

I just moved to alpha20 and my car starts fine. My accel is smoother as well. only issue i have, is what I just had happen, was the fan control. I set it to allow it to be on with engine off and now I can't get to run with or with out thtis setting... :? . Trying to figure it out now.
