Does it do it in T/H when the converter is already locked? That seems like a good test of the theory.

But the RPM isn't dropping? Shouldn't the RPM drop when the converter locks?

I did'nt think there was a defuel when the converter locks? I don't think ive ever seen a defuel when the tcc locks at WOT, but it locks in second at WOT?

If you tune everything so all of your max's are the same a 90% of throttle, does it still defuel short of WOT?



On Edit, the LLY is going on 5.5 years old and we still don't have them figured out.

could tables B0761 thru B0770 (Main Pulse Quantity Compensation) have anything to do with the problems, B0761 is zero'd out, but the other nine tables appear to make adjustments in different areas of the tables. Would possibly zeroing out all of these tables be of some benifit?

Has anybody adjusted these tables?

What I mean by trying it in T/H is that the converter will be locked and if you duplicate the test and it doesn't do it, then you know it's defueling to reduce converter slip for lockup.
