Regen question...

[BigKid]

I recently tuned my truck back to stock, but left my Dash Daq up just to see how mine acted during regen. What yall are saying makes sense, During the regen period, at the red light it was around 600 - 700 degrees, and at a cruising speed of 50, it bounced around to 1200 - 1300(not even pressing it hard, just cruising). I didn't get it on the highway, I was on my way to work, it was city driving. But at every red light, it would come back down to 700ish. And when I finally stopped at work, I sat there for a couple mins to see what it would do. AFTER I put the truck in park and sat there a couple mins, the temp came back down to 400ish.

my truck goes into regen at 150-225 miles and only when i need to be somewhere. Also i have a strange whistle from the turbos while coasting at 35-40mph. anyone else?

The recall should have provided you with a letter explaining regeneration characteristics. Every truck I have ever driven has regenerated below 35mph (regardless of calibration level), however they no longer regenerate in park as they did on the job 1 trucks.

Yes, the turbos will make weird noises during regen.

6-700 degrees seems about normal for regen at a stoplight, and 12-1300 seems normal at cruise.

There is currently a later calibration available than that recall, but it's to resolve some driveability concerns and false check engine lights.

I have all kinds of wierd noises when mine goes into regen. Have you noticed at close to the end of the cycle how it sounds like the turbos are cycling back and forth? I can only hear it when I am going 35-45 mph.
