B0720-FRP: actual or desired?

[killerbee]

We learned that in earlier ecms, that pulse varied with "actual" FRP. Is this not the same? Presently it shows desired FRP.

Me and Racehemi have determined that it is based on FRP_C (actual) thats the only way that table makes any sense. Wouldn't make any sense to have a PW based on commanded and have actual FP be way lower. You'd be all jacked up trying to tune for that...

I agree with you. It is something that seemed to be understood 4 years ago, if memory serves. But the table is still loaded with desired. At least mine is.

Yeah the cal_link is that way currently. The table description is actually wrong as well and should be fixed too... (Me)(Ross) I have actually updated cal_link.txt since we had figured that, and a few more tables as well. Here's the latest version.

Thanks for offering it up. That beats fixing these myself.

[bballer182]

Yeah no prob.

Interested in how you came to the conclusion that APP_D was appropriate for pedal to desired torque, B1161?

Using that, when at idle, it shows a non-zero value. A little hard to get my head wrapped around, but it seems to make more sense. How would you define or describe APP_D?

[bballer182]

Uh you might be right... Have you tried APP_E for the LMM? I think i remember Nick saying something about using E for the LMM's. APP_D is correct for the LBZ, though...

Try APP_E for the LMM and get back to me and i'll update the cal_link.txt....... AGAIN.....

LMM: APP_E is worse than APP_D. I just have to reconcile 18.8-19.2% throttle (app_d) with foot off it. It gives me a headache trying to understand why it would be set up this way.

I used TP% for LBZ with good results.

TP in BBL mode does nothing. it reads a constant ZERO. and APP_D works in both so thats the one i used.
