Hi, my name is Tim Iacobucci. I have a decent running modified stock tune for the mods listed in my signiture. I have been trying to either modifiy the zxa5 bin to work with my auto and/or implement the decipha recommended settings in my stock tune to work akin to zxa5. Both unsuccessfully and for different reasons. The engine runs very well using the zxa5 base but the transmission acts a bit crazy even with all the transmission related parameters available in the sailorbob def being identical between my modified stock tune and the auto modded zxa5. It acts like the TCC is cycling rapidly at higher load and it really doesn't want to downshift even though I have the shift curves super downshift happy and it is does downshift very readily on the modded stock tune.


BCSDC stays constant, what else should I be looking at in the log to see what the tcc is doing other than SPD_RATIO? I'm guessing at this point there must be other parameters which affect the transmission function that are not defined in the sailorbob definition.
Here is a link to that log, I can't attach .csv files here, how do you usually share logs here?

And here is how the working prldsw 1 modified stock tune looks

And lastly in BE prldsw is listed by description not number value

So, load/peak load =0, load =1, inferred load % =2?
I've attached the 3 relative tunes and I have logs I could share for each as well.
