Cursed EPA BS! I found that when calling around here in MD. We only do race cars, we don't do street cars etc.
I started telling them my truck identifies as a AutoX champion...

I wouldn't help you either mister nasty face JFC you are aggressive with every person that responds to you. Go get laid.

Getting frustrated. Using EQ error histogram and this thing stays rich.

I really appreciate the help Billy. Getting there!

Start up and idle WAS problematic. It is fine now. Cause was dead IAT sensor. I replaced and scaled a Rife sensor and it now starts and idles fine.

What info would you need? I did put what I know in first post. I did find the dead IAT and fixing that was a huge help.
Going to hook up wideband to MPVI3 tomorrow.

Ran it today with new scaled IAT. I could actually get into boost finally. Could someone look at my latest log? I am hooking up my wideband tomorrow but actually getting somewhere.129098

So the IAT sensor was dead. I replaced it with a Rife. Started car and the Rife started out at 14 degrees Fahrenheit and climbed into the 30s.
I recalibrated with their table and all was good on...

Open a ticket for assistance from them.

Tuner recommends the dw injectors so I'll go that route. I bought the truck with plugs gapped at .040, I replaced them with TR6 at .028 Also replaced wires.

So playing around today I flashed a different tune, then immediately flashed old tune back on and my idle issue is gone.
Still can't build more than 1.5psi without it acting like it's breaking up....

Thank you Bill. I certainly appreciate it.

Thank you. It is an SD tuned. I'll check IAT sensor. I'll also hook my wideband up.

So I just got unit back today. No info on what was wrong or anything but it works! I pulled a log and hopefully someone can help me.

OK finally got my new MPVI3 sent back to me from HPTuners. They never told me what was wrong or how they fixed it, kind of ignored me but I got it today and it works.
I am adding a log here....

SO I am new here but not completely new to HP Tuners. Last car I had MPVI2, now I have a 3 and can't connect or read.
So I used a shops MPVI2 to pull my tune. That is why I have no datalog, I should...

I did just send Eric the info log.

I have an 02 Sierra with turbo LM7.
I lost my MPVI2, so purchased a new MPVI3. My software recognizes it until it is plugged into OBDII port. Port is 100% functional, tested with voltmeter, scanner,...
