Low Performance 6.7

What Duane said.

Post the tune that you're currently using and Id be happy to look through it for you.

Have you adjusted the limiter tables?

Which ones? Basically I have anything that can be disabled -- disabled. So all that stuff should be disabled. I had to do that just to get it to run without a VGT and all the other sensors and modules that a OEM Dodge truck has that my Fumins doesn't have. And that's been somewhat of challenge in itself.

I think I got it attached. Here's the file I'm using. Good luck. It doesn't fuel above 94 mm3 either.

Ill look at it in the morning with fresh eyes, do you happen to have a log of it not fueling past 94mm3?

And you just do not have a VSS feed into the ECM correct? All other sensors except VGT and VATS/security are there?

What are your goals with this, how many RPMs do you want/can you run? Mods on the motor?

The tables that I'm talking about are under the "Injection Quantity" folder. You will see about 7 or 8 sub folders in there. One of them will be "Limiters".

I'll take a look at the tune this evening as well. Eric has a lot more experience with this than I do though so I'm sure he'll figure it out...

CMC_0002 DTC Disable_1.ctzdisabled the other limiters for you. A data log of your truck driving would definately help get it running right.

I've adjusted everything I could think of...and still it hits a mm3 limiter.

Increased duration below 90mm3 and got it to run ok...but still SLAMS a mm3 limiter ~90mm3

Les, I would say that it is the load based limiter that is killing it. We have a fummins w/6.7 that should be running in the next couple of days and I imagine I will be fighting the same thing. When Zach and I were tag teaming Richard Madsen's truck it reacted the same way.

What was the fix? Or wasn't there one?

Sounds like the 6.7L load based stuff, is it related to the lack of a VSS signal?

Ive never done a swap like this, the guys that have probably have a better idea of what's up.
