Gearhead MCC dyno numbers?

3brorce · Apr 29, 2013

Thats what I did but now mine does it no matter the tune.

Erikclaw · Apr 29, 2013

Mine only did it with KEM and Spartan's tunes. Innovative or Gearhead's didn't give me those issues. I would going to a shop and have them run the Ford software (?) to see if it is the tune causing the issue or if the trucks cpu is commanding it. At least then you will know what is causing it and see if it can be fixed.

I'll try the hd300 out again.

Gearhead · Apr 29, 2013

If the converter can't relock fast enough after the upshifts because it is on it's way out, the computer will not let the converter try to relock to "save" it.

I had to read that 5 times.

Csilva187 · Apr 29, 2013

I'll have to pay more attention. Thing is anything else it does just fine. Just that kinda on it kinda not throttle it'll act strange. But I'll pay more attention defiantly now.

Do you think this could be why mine was acting up?

Yep... your builder fixed it with more converter clutch flow.

Ok fellers I'm pretty sure my converter is weak. Even if I just tune down to Matt's MCC "stock" tune my converter locks in third and stays locked at that 50-70% throttle area. If I turn it back up I get that ****y unlock in 5th then lock back up into overdrive. Thoughts? Appreciate the help again Matt, Erik, and all others!

I've been running on the street setting myself. I'm not studded yet which is my main concern. Anybody else ever have there rig lockup then unlock to about 60-70 or so then lock back up into overdrive? Only seems to do this at about half pedal area? It puckers me pretty good when it does this. Forgive me fellers I'm a newb, I'll admit it right now.

My truck is doing all the same unlock and lock stuff. It drives me crazy. Also at freeway speeds if I floor it it will go down to 4th but the tc wont lock until 5th. New suncoast clutches new rcd tc.

Mine acts funny sometimes also at half ish throttle and it scares me. It also drops into 4th unlocked on highway if I floor it and I think it should drop to 4th locked. Maybe some bugs needs worked out.

3brorce · May 13, 2013

Mine does the same thing.

Dzchey21 · May 13, 2013

Its a odd issue that I'm not sure there is a table for

Gearhead · May 13, 2013

The truck is seeing too much converter slip and not allowing lockup in those situations. There is a parameter buried deep in there and nobody has dug it out yet to give to us tuners.
