TCC@85

[Tim Hensley]

got a new Alky chip from TT(4month a go) locking converter @85 that is all it took to get me to my target 11.90 ET



just installed A powerlogger thought I would see more RPM drop (150 rpm) than that?
 

any thoughts?

I would have guessed 250, but ymmv

On the other hand, you may be making enuf power to overcome the clutch lock and it may be slipping a little.  Unless you have a good multiclutch converter, locking the converter usually wears out the clutch material (burns up) with time

convertor is a EDGE carbonfiber clutch

spent about a hour on the power logger Third gear CS factor and wallace racing converter slip calculator

PL speed reading will be low 100mph PL actual mph 104mph I see no speedo offset but I believe I have the proper CS%

32% @85 -12.7%@112  try trap speed

[Steve Wood]

drive the car at a constant speed in third gear so the converter is locked...see if the cs is showing very close to zero...that will be about as close as you can get it...

got GN out today,got the CS down to 1% on the PL,

PL doesn't show 4th gear when it is in 4th,TCC light up,probably no big deal

[Steve Wood]

4th gear switch is bad, it would seem.  Don't think it makes any difference on the modern chips

Thanks for the post on turbo tweak forms.
This car gets a lot of shakas on the return road Im the only car in the 11.90 class going through the mufflers and not showing up on a trailer.
The forms have been a lot of help I have read Vortex several times
Got the CS to 1% I bet the 28 in slicks will change it again but no big deal,Edge said let her rep the clutch will take it
