Gearhead MCC dyno numbers?

Gearhead · May 13, 2013

I will see if H&S can locate the parameter. it isn't hurting the converter, it is just not allowing it to lock again after it unlocks on the downshift.

So my new converter is slipping? Doesn't seem to be.

I'm glad it's not just me with this going on! Has anybody else turned the wick down and noticed it'll run just fine?

That is pretty much a given in that it will shift fine with less power tune.

I gues I haven't tried it on a lesser power tune. Wouldn't it do it at any power level if its a tuning issue and only at a high power level if its a converter issue?

From the way I understand it the computer senses it is being overloaded and is preventing lockup, on a lower power tune it does not sense the overpowering issue and does not act on it....

the higher stall the converter, the worse the issue is.

Matt I have a lower than stock stall and I would say I have it pretty bad.

??? Is there a fix in the works? Been like 3 months plus now.

Its basically in the torque converter slip. When unlocked you are allowed a percentage of efficiency so the lower the stall the better as well as lower the power. Usually once you gain some rpm the Trans has less of an advantage (ESP right before the shift into the next gear) and it will lock.
They also sense slip with the converter locked, if its over a certain amount the converter will unlock. Then it may fight to re-lock anyone having issue should monitor tc slip and see at what point they have issues with it unlocking and report back

This isn't making any sense to me. The rcd converter is very efficient unlocked and holds way more than I have locked so why is this tuning so out of whack? HS tunes don't do it. KEM on SCT didn't do it.
