So last night it was getting dark and I managed to get CMP set at +6 thinking I would set it tonight. Well it seems to run better.
I also validated the pids today in dash command and it still will not read misfires.
Have you done a crank relearn yet with your 0411 installed?

We did the relearn at BB when i had a in person tune.

BB also tuned my truck with EFILive.
It was also relearned twice with the black box about 3 weeks ago.

So, since you put the 0411 back in, have you done a crank relearn on it?

I'm not sure how long either computer can be sat on a shelf or without power and hold that data. Maybe it's written to the ROM somewhere and permanently stored? Idk.

No i have not. No one around here will mess with it as long as it's a 0411 and not the stock black box.

I could put the black box back in and for $20 get a crank relearn done again but im pretty sure it will change nothing as it has not in the past.

That's a shame. I would honestly trust the 0411 over the black box honestly. There's not any tuner shops around you?

And because the 0411 hasn't had a crank relearn, that's why you can't see misfires. Same thing has happened to me and why I didn't get a misfire-related code until I had a crank relearn done.

Anyone around here wanna take a road trip that has tuning software for this guy?

Tell them it is an 02 350 van and to crank relearn it as such. I bet it defaults as a van anyway unless the VIN in the PCM has been changed.

My van scans as a 2005 L31 Mexican truck. Has not caused problems with any of the scan tool programs I have connected to it. I did the crank relearn and read the CMR with HP Tuners though.

The vin was changed to my 1998 suburban.
I have called the shops around here and none are willing to do it. I have even put a ad on Craigslist offering to pay the for the credits and a couple hundred extra cash trying to find someone to do it.
I should just buy it but dam with the initial purchase and credits i just can't bring my self to do it.
Sounds like the best option is put the black box back in and get it relearned. I do know with a 0411 not learned it runs slightly better.
I also think BB did something with the fuel trims. The LTFT will get to - 14.84 on both banks and stay there.
