A960E Automatic Transmission Tuning

So, I know the TCM/TCU is locked/not "developed" for the 86 platform and by the looks of it, it may never be looked into.

How do you FI/turbo guys get around the shift firmness (Line pressure), torque converter lockup, rpm shift point control etc with the auto?

I've been trying to use the torque/ DBW tables to try to "fool" the TCM and get around not having direct control for shift firmness etc.

it turned into it "getting" there and shifting how I want it to, but it turns the car into a sensitivity jumpy mess (with the DBW tables).

(Car is still N/A right now)

I came across this old 5EAT thread and by the looks of it they used the (Target throttle plate position Requested Torque) table to fool the TCM into shifting firmer than stock on that platform)

https://legacygt.com/forums/showthre...re-149282.html and from reading that thread it seems as if it was doing atleast something.

Has anyone ever fooled with this table on the 86 platform to see if it does anything on the transmission side? (By the looks of it, it controls and is formatted way different on the 86 platform?)

There is really no newer info for the 86 platform and the A960E on the tuning side.

My guess is because majority of these cars are sold with the manual, and the automatic is a small minority.

At this point I see SSP has a valve body and torque converter out and that's about it.

Has anyone looked into, an external controller for the A960E such as a PCS or possibly trying to see if its possible to do a raw stock TCM file dump with external tools?
