I too need this!

 

If you're talking about the TCC releasing on decel then this is what I did to make it stay locked until it reaches my minimum release speed set in other tables. Works flawless and it ill release when I hit brakes and apply when I let off brakes. The 60e would release when I hit brakes and then I had to give a little throttle and It would lock then, It now locks as soon as I release brake as long s I'm above the min VSS release

 

Mine has Low speed and High speed at 256 and the rest zero like pictured above. So on that note, it doesnt seem the low and high speed make a difference but rather that the rest is zero'd out.

 

My version of Hptuners doesn't have that minimum throttle release column on it. Can't update the software either since I'm using the old school serial cable. Any way I can change this without that column?

 

As far as I know it's in the 2.24v release. My software came with 2.23 and it didn't have that column until I updated on the HP website

 

That table is the only way to change it.

 

I believe that this is likely the source of your problems. The PCM/TCM needs that input speed sensor information.

 

All the harnesses I seen still had that speed sensor hook up. As Roger said, the PCM needs that input. Unless the frost harness is made to operate off of a 60e tune? If that's the case then no segment swap is needed.

 

Wiring in the speed sensor is the easiest part of the 80e swap.

 

Yes, its very simple.
