Heading to the track in the morning

Les

are you changing the axis table for the MAP sensor as well

No..just simply changing the psi to go linear from 0-58psi...I'll try to post a pic tomorrow.

Les,

That was more than likely the issue.

I just looked at that table and I didn't change it. It still had the 51.4 as the limit and I hadn't rescaled it.

I could have sworn I did, but apparently not.

I'll get it loaded up this afternoon and see what it does.

This is the EXACT issue we are having as well. I havent tried rescaling the map voltage tho. PUll to 3k, fall on its face, smoke would go away, shift and pull again thru the next gear. When the tc is locked its more apparent.

We did better than we thought we would tho, 12.6@107 hitting the limiter at 107.

Here is a screenshot of my MAP voltage table...

Les, I just tried your E3255 map (MAP Sensor rescale), and with the truck idling, I got a P0236 Map Sensor Too High Too Long. Any ideas?

I have heard of this with stock trucks...possible causes are...dirty MAP sensor..or failing/lazy sensor.

I have this MAP on 4 trucks right now..and have been doing well with no codes.

You need to adjust the turbo parameters so it doesn't look for the boost error....

Yea, already touched on those Rich. Les, I don't doubt you at all, just curious. I'll play around with it when I have more time. Speaking of what you said though...do many people clean their MAP sensors?

[2007 5.9]

I clean mine as often as I clean my air filter....but I am very particular about my set-up.
