Did you do the crankshaft position variation relearn?

Think that's how it went down. I never really paid that much attention on how I used to do it because I never had a problem before.

Bricked my first ECU last week. I was three steps into my idle tuning on my DBW to DBC conversion and now I have a nice ECU shaped paperweight.

Before last update I had never had a problem (lucky...

I wish it were that easy, alternator case grounded direct to frame, battery grounded to frame at same spot as well as engine block to frame and battery to frame at rear of truck. Redid all engine...

Inside the connector it has a green or blue key, can't see from outside.

It's bonkers to me that they wouldn't be as they are a basic input/output. Those voltages are on the CAN network for sure, just appears that somebody at HP tuners hasn't taken the time to translate...

We've come full circle now. I have followed it as far as I can go without measuring the voltages in the throttle body, which brings me back to the original question: How do I log throttle position...

I can't find brake torque management in my TM tabs. I can't adjust limits for 1516 - only can set limits for 1514 which are already set to 4.0. Engine cuts off at idle when cylinder airmass is way...

Here's latest tune file from today. Couldn't get it to go into REP today (of course), but I did attach a log from when I did get it a while back.

HP Tuners support said "try scanning those pids" ...

Oh and I lowered the threshold for P0068 since then, I'm pretty sure I was bumping the limit on vacuum at idle haven't gotten 68 since then only 1516

Older version posted here im mobile today can post latest later tonight

Anybody willing to offer any help before I swap ecus and os for a DBC setup?

I created a new vehicle profile today and repolled for supported values (I tried not polling for values on a new profile too) and I don't get any pedal or throttle voltages.

These are the only...

Been battling reduced engine power issues in my 05 Silverado for almost a month now - has been a P1516 regularly, but have received P0068 and P2135 - and I can't find the voltages for the pedal and...

Was the stall saver tables, they were set to same speed as idle speed, doesn't really say what stall saver does, but since setting tables back to stock, the AC works at idle

So if I hold RPM up to 1200-1500 rpm AC clutch will stay engaged. Tried bumping up idle RPM to 925 - no change.

I tried loading up old and old old tunes from last year and neither works either.

2005 GMT800 Serial Cycling AC System, P59 ECU

AC compressor runs enough to pull down to 65-75 psi on low side then cuts off. Will not stay running unless I jump compressor relay. Only stays on...

Says it's in the supported vehicle list - MVPI2+ is what I'm using - all I get is this:

What all would need to be done to keep the transmission (4l80) happy on a P59 in SD only? I've never had much of a handle on tuning the transmission - my tranny guy said to jack up the line pressure...

Goofed around last year a bunch, not know what I was doing - and ended up wounding some rings in my 6.0 swapped into my 2005 RCLB 1500. Still not 100% on what I am doing, but going to go slow and...

When you adjust the numbers down in the VE table, shouldn't it get leaner? - I tried to get my SD dialed in to get out of MAF only but it runs pig rich - shows 11.5-12.0 at idle even after I cut the...

I guess this is the lazy way to tune it and since I didn't know any better at the time, the guy I paid to help me set it up this way to make a quick buck. He came highly recommended, but this is the...

Depinned the ISS from the TCM and it started working thanks for the help

Trans is 4l60 from 2002-2003 hummer and truck is 2wd

Harness came from Current Performance

Thanks,

I also noticed while looking through the logs that it's not calculating the gear ratio correctly - instead of 0.7 in OD its ~2.0

Truck thinks it's an 08 trailblazer
