Default Spike to 7 KR

When.....not if .....I punch it moderately from 30 mph and it downshifts to 1st or second gear, I am seeing a spike to 7 - 9 KR, then it decreases to 0 after few seconds as the revs climb.

I have the standard Intense PCM but I'm not sure how much of the torque management has been disabled.

Back on topic

Matt are you still running the air filter of the stck accordian tubing with no heat shield?
Ive been told that only 50% of the TM is removed with the Intense PCM.....
With the power your putting down aren't you happy you have some torque management to save your tranny :P

Paul, it sounds like you have KR at the higher rpm'*, and after the shift, at lower rpm'*, you don't have any.

Your supercharger is belt-driven. Sounds like at the higher rpm'*, you're producing some heat and boost-stacking. And the weather is cold right now. Even with higher octane, you may have to step up a size on your pulley for the GenV.

Paul you should ask Todd how much if any torque management remains in the standard pcm. Then I would look at some possible false knock.

From my talks with Intense, about half the TM is removed.

Although.. TM shouldn't cause KR, it should pull timing. Knock causes KR. This is why I hoped we'd split this off.

I assume that this includes when you are keeping it cool with the juice?

How much PSI are ou getting at the top of the shifts?

TM (cut timing) could be displayed as KR though on the Aeroforce couldn't it?

No Bill, it'* the opposite.
No Kr at upper rpm, just from 2500 to 3500.

No Boosty. This is with the water injection turned off.
It happens at aroun 0-2 psi boost and as the boost builds it decays to 0.

13 psi at 6000 rpm
