keydiver chip problems

[talonkev]

I installed a keydiver chip, 780's and a 190 fuel pump. The car idles good, pulls hard and runs smooth. The only problems is that it won't rev past 6500 rpms. Every thing on the logger reads fine so I'm stumped. Its an auto and when you get on it, it normally shifts at 6500 so now it like bounces off what fells like a rev limiter about 4 times, then shifts gears. The rev limiter was supposed to be programmed to be 7500 rpms. Has anyone else ever had a problem like this? thanks

do they know it was an auto? sounds like they programmed a no lift to shift feature at 6500rpm

OK, I had this same problem but it was at 5500rpm when I first installed my Stage 3 DSMchip. I sent a PM to Jeff aka Keydriver on his forum at DSMships.com
And this is the reply I got for us A/T guys.

"Cut the wire off PIN # 104 from the ECU, then the PIN side to the ECU needs to be grounded for the neutral safety switch to be bypassed"

Once I grounded PIN # 104, the car would shift like normal, without hitting the rev limiter of the "no-lift-to-shift" function for the M/T guys.

Works like a charm...
Good luck and happy tuning.

Jeff is on a trip now, so he may not get back to your every request right away. I'm sure he'll answer it in due time though.
