optishift transmission controller

[obspsd]

Does anybody have any experience with these units. I've been running one since I converted to auto but I have a few fine tuning questions

 

[obspsd]

Dam, nobody?

Is this the same as a PCS controller? Of different brand? I know they have the same end result

All I use is pcs. But what's your question ?

I can't seem to get the converter to lock in any gear but 4th unless I lock it manually with the switch. But once it locks in 4th I can click overdrive off and it will downshift to 3 and keep converter locked. I'm sure there is something I'm overlooking in the tuning software

 

[Dieselboy.]

Do you have your unlock tables higher then your lock tables ?

Also. With my pcs I have a parameter that no matter how early I command lockup in any gear I can set it so it won't allow lockup past the gear I've designated.

Other thing is your lock up table. If you command lockup after a shift point at given TPS it could cause issues

Hmm sounds like the pcs has some more tuning adjustments. I can tune the shift points really well throughout the tps range but the converter settings seem kind of vague

 

[Dieselboy.]

I have a few tables to tweak tc operation.
I bet it's something to do with your lock/unlock mph. Just overlapping weird with TPS

Alright I'll check that out this afternoon. I'll let ya know what I get
