Not getting maximum duration?

[TexasCummins]

I am having phantom issues with fueling now as well with the newest release. Even after disabling all the limiters again from a clean stock file it's very hard pressed to get past 2,900rpm.

like its defueling completly at 2900 cus it seems like that too me too

I just double checked all my fuel limitations and took the truck out for another run. Once I hit ~2,800rpm the fuel goes down and the motor won't even kiss 3,000rpm. I had no trouble running 3,500 before the update...

I went to the dealer, got a fresh flash and now all is perfect.

^^^ This x2. Ross is working on fixing other people's problems. The crappy box tuner that messed your check sum routines up. People who read this need not to think of it has an in-convenience to go to the dealer for a legit update flash, but as the proper and right way of tuning your truck. You won't have to worry about any more headaches or "ghosts." It was something that was a no-brainer for me since I know what I'll be running tuning platform wise for A LONG time.

The base tune I'm running is the one I had flashed on the truck by the dealer due to a previous tuner not fully going back to stock and throwing an internal ECM failure code. It's a clean stock tune but this new update can't seem to disable to fuel limiting around 3,000rpm even with the parameters disabled.

Yes, I am running efi's latest release. I have my rpm limiter set at 3500rpm, and get full fuel to about 3100rpm when it starts pulling fuel slowly to 3500rpm.

I can understand that starting off with a completely stock, never been modified tune, as a base. What I don't understand is why you cant just use one of the stock tunes from someone else, and flash it yourself. Why have to go to the dealer?

You're hitting the P.I.D. limiter.

It pulls fuel as you approach your RPM limit.

One of them, either P, I or D is set to ENABLED. More than likely P.

P is enabled by default on my stock tune, and I disabled it. I and D are disabled by default. I changed the rpm low and high range to 4000 and 4500. I had our mobile reflasher do a complete erase and reflash build by VIN since he was here already doing a customer vehicle, and I'll see what happens from here.

With a real reflash on the ECM the truck drives insanely better, and this is a stock tune.
