truck towing pictures...
Well I don’t know. The last trip the truck was still down on power and would go into stage 1 limp climbing hills. And it was random. Fuel quantity would be limited to 55mm3 and then just come out of limp and accelerate again. Even on flat ground with a head wind it was down shifting into 4th. It... -

Did you put a factory GM MAF back in? You don’t happen to have a Fingers stick on your truck do you?- darkness

truck towing pictures...
Today I hooked up the flatbed and loaded up an Expedition and headed out to do some logging. The truck ran like shit the last time we took the 5th wheel out, so I made some loops up some decent climbs on the edge of town. Anyways I digress lol. -

Lml unknown ecm tune
With a dsp5 switch I would assume you got at least 1 hot tune. Hopefully you have some gauges. Your best bet would be to get some kind of digital monitor such as an idash or edge cts 1/2/3. Then you can select some different pid’s such as timing, fuel pressure and pulse width and get a fairly...- darkness

Shake down weekend
B0852. Apparently sometime between ‘02 and ‘04 (I’m guessing ‘03 😜) they changed that table. I don’t ever remember having trouble with cruise in my ‘04. Fixed now and we will see how it goes. -
Reduced engine power no CEL or codes
No other fuel pumps in tank or in line. Only the cp3 in the valley. -

anyway to unlock efi live tune
Correct. So without knowing if it’s the tune or the ECM, at least he knows he has options. My truck had moonshine tunes and the ECM was locked. I couldn’t flash over it. Also SoCal doesn’t use a bench harness. He replaces something inside. For a $50 extra fee it can be expedited and done that...- darkness

You can send it to SoCal Diesel and they can unlock it and put a stock tune in it.- darkness

Shake down weekend
Well we took the trailer out for its first shake down. Everything went pretty smooth. I had a problem with the brakes the minute I left the parking lot the day I picked it up. It would show a short every once in a while. While my truck was down working on the suspension and unlocking my ECM I... -

That return line is a major pain. 2 trucks I put my own lift pump on sucked lol. Just keep working at it. -

I know this isn’t a fix, but those 2 lights have been on in my parents ‘01 Yukon for years lol. They haven’t experienced any adverse braking problems with it though, just the lights on the dash. -

You don’t NEED a lift pump. Just highly recommended. -
01 crewcab 6.6 turbo 127k miles
Yep. The stock fuel system run in a vacuum. It will run under pressure with a lift pump. This may not be a popular opinion but I’ve removed the stock filter head from my first 2 trucks. My ‘02 already had it removed. With 2 filters on the lift pump there is plenty of filtering. If you feel you...
