#4284, "RE: REVIVAL OF THE OLDEST" In response to In response to 9
Originally posted by mcgyvr pretty sure your still limited because its a 95 with a funky tranny computer. PM ryan95i4 for info on that. he knows what works/what doesnt for the 95 as far as the stall speed.
I had a built atx with a 3K stall in my car before I swapped to a mtx.
At the line, I could build 12-15lbs of boost with ease (s16g), and bring the revs to well over 4K rpm (brake stall). The problem is the 95 tcm sees this high stall as slippage and will put the car into limp mode (2nd gear only). Even while launching 2nd, the car would still light up both tire 1/2 way through second, but...only second gear was available.
The issue with the early tcm's was what it saw as slippage. When brake torquing, your input speed sensor is seeing lots of speed, and your output speed sensor is seeing nothing -- when this becomes dramatic enough, into limp mode it goes. Im told 97+ tcm's do not have this same problem, but then, I dont know anyone who was actually building over 4K rpm and a bar of boost at the line either -- I believe dougie may have been, but its been a while since I kept up here.
I had planned on putting in a 97+ tcm to try and remedy the situation in attempt to salvage at least one track session, but swapped in a manual before I ever got the chance -- one of the few stock parts in the tranny, the OD clutch hub, sheared off and I refused to put another dime into another a604 ever again (now that the a604 is put into turbo PT's, DC has upgraded the clutch hubs -- had this been an option when I built mine, I would probably still be using an ATX, but that was many years ago ).
As far as drivabilty went, the car was daily driven without a problem. the 3K stall didnt prevent casual driving at all.
