Hello,
Been a long time since I've posted. I'm having some issues getting an aftermarket stall to lock the converter clutch. Seems this operating system only has an apply ramp and max pressure tables. Well, I'm commanding 150 psi through the apply table and I have the max table maxed out. I'm seeing 50ish PSI on the scanner when it goes to lock, and the clutch "bounces". I can command lock up using the scanner bi-di controls and it commands 594 psi, and locks up fully. I've done way more cars than trucks and in hundreds of cars with countless different stalls, I've never experienced this problem. In all the cars there's a 'regulator gain' and 'regulator offset'. I'm pretty sure the offset is the pressure "clip" I'm looking for but tech support tells me it is not available in this OS. Wondering if anyone else has run in to this and what they've done to work around it.
Seems really strange the trucks don't have these regulator parameters, but the cars with T43s in the same years do.
Data log and tune attached.
In the data log you can see the TCC "bounce" at 3:06, 4:18, 4:32. Around 9:14 I lock it using the scanner controls, it commands 594 psi, and no bounce.
TIA
