Nelson tune, have a question

[danalihd]

I had no idea ltrims were measured by the Predator. Oops. Anyway Allen, after talking to you last night, I hooked up the predator an made my way home from work. I noticed the ltrims bank 1 and bank 2 were all over the place with normal driving. Anywhere from -10 to +25. Even though it was 2deg out and windy, I decided to try it WOT. Bank 1 was 5.5 and bank 2 was 8.something. 90mph. This was the only time they stopped moving. I definately don't recommend going 90mph while trying to read a handheld tuner. I found myself staring at the tuner and not the road. That almost sucked. I'm on my way to the dealership now. I'll have them hook up Tech2 but NOT flash it. Also, the code I am getting IS P0101. I have been getting this code since I installed the Whipple and this is my second MAFsensor. I am replacing the stock airbox with a cone filter asap. I should have it in the next day or so. I didn't know if the supposed increase in airflow would fix the code.

Your ltrims aren't that far off, on a very cold day, your ltrims will acutally go up, -for example -8 to a -3. Did you get a reading on the 02's.

The P0101 can occur on a boosted application. If your maf is flowing more than your maf is used to seeing, you'll throw that code. I do adjust for the additional airflow , just like your superchips tuning should, but you must be flowing a lot more air than a normally charged truck does. I'll bump those settings even higher and get you another pcm shipped out next week.

thanks for the update,

allen

BTW, your truck should get better with more miles, now that you have more miles on your truck, how's it feeling?

thanks,
