Ok thanks. I will stop chasing my tail on the idle, I dropped it from 24 to 19 to see if it would change.
Would 20-24* be crazy off the line? I'm not sure what's normal in that area.

I got two questions
1. my timing at idle jumps around +/-5* I have tried lowering my idle timing, still moves around, and double checked my BRAF, seems ok. I didn't think its normal for it to move...

Couldn't tell you, I have never messed with one. You could proably find some tunes in the repository and compare them. I do that a bit when I trying to figure somethings out.

Just thought I would update this
Fast sorry I never actually saw your post, will have to look at my notification settings. Lean cruise has been a thought after swapping to dbc one day maybe. ...

Ok I will look at that this weekend. Thanks

I'm not sure where to start looking for help, but figured I would start on hptuner forum.
My truck seems to pull timing for knock retard randomly, under acceleration, or just cruising at 70. It has...

Oh man your making me really want to put a cam in it!
I think his name is Timm, he has some older post on prefornacetrucks forum I think. He talked about flowing each runner and match the flows...

1970ss out of curiosity how different are your commuting and towing tunes. Mostly just timing changes?
I may PM you later about getting a tune from you between not driving it much and cost of...

ok new one to load in, changed the pe, I really like that idea of ramping it in at low rpm. not sure why I didn't think of that cause I do that on my s10.
Proably be the last change I do to it...

Got it out today. Changing the stoich helped out with a lot of the KR. Deffently need to adjust my PE throttle percent enable lower. I think i lowered the rpm down to 2400.
Either way thanks...

1970 thanks for the tips. I will make a few adjustments. I have not messed with the timing tables at all yet. I put the rpm delay in it to help with winter traction in cause the wife drives It at...

wow that's a lot of info. I plan to do plugs, mess with intake, add electric fans, maybe exhaust. But some of it will take time. Would like to go into head cam and intake but that will be a long...

It's a 04 yukon xl, so yes a suburban, all stock. Just got it. Plan on a few small mods later. I can post the stock tune and the one with the few changes I made already tonight. I have not tried...

Are there any general guide lines with these as far as how much timing and setting up trans for fuel mileage and not taking out the TCC like the 8.1s like to?
I just got one for a tow rig and...

one year later coming back around this to again. got the dfco to stay on now. I had the entry and exit map tables set to close, I miss understood them. I was hoping to get some crackling out of it,...

I found the data sheet for the temp sesnor in using
delphi manifold air temperature sensor datasheet
And it shows temperature compared to resistance. The table has temp vs percentage. How do I...

Shouldn't. 4l80e unlock when coasting

finally got a chance to upload copy of tune

I thought that was more for heat soak sensor in traffic or hot restarts.

Is it normal when running speed density to have the fueling change slot with air temp. Leaner with hot ambient rich with colder air? I had mine tuned pretty close and now with 40-50*F cooler air...

Sorry to side track but when putting in to speed density disable misfire counts too?

Bummer. So what would affect it that much. Cant post tune or file right now or I would. Running speed density is that just how it is?

Would wrong injector offset data cause it to run richer when air temp is cooler?
I had the fuel pretty good last summer and now it's running about 10% rich with about 40*F cooler. Just wondering. ...

What have you tried?
Posting tune and log of what it is doing will help too. I don't know a lot but can try to help

Sub for info. Have same issue.
