we put a 40-94 on my lmm and it runs realy well for 10 mins and then goes into limp mode i belive the problem lies within two codes p2033 -p2564 is there any way we can get acess two thees to set the test drom never running so they dont time out. or shut off limp mode alltogether. limp mode sucks :Eyecrazy: :help2: Thank you

Do you have anything hooked up to the VVT position sensor at all?, or is it just totally open circuit?
Should be able to come up with a solution for that though.
Shoot me a PM with your Email address, though, not much will get done over the easter break....

Cheers,
Ross

The main aim was to get the truck running to a point where it never limped, that was achieved, there is still some nagging DTC's but they aren't causing any issues.
I sort of got pulled away from working with fire0021 to get the DVT additions sorted. But, the urgency was gone and the truck drives, that is the main thing.

Cheers,
Ross

Tommy do you, Mike, or anyone else with aftermarket turbos on LMMs have any check engine lights or codes coming up?

Well with alot of help from ross we where able to keep the truck form limping and i was able to track down the correct settings for some of the permaters to make it no even want to go into limp mode. I was able to run consitant 12.40s in the truck and it ran great no issues no codes no lights. If you have any spacific questions let me know and i will do my best to help you out. Tommy. Now testing another new turbo se will see how tht goes :doh2:

Any thought tommy why I show codes, just no light? The codes I can pull are even set to not report.

wich codes are you getting? the light will not show becuase they are set to not report. but tht basicly just keeps the liight off. I have found a few fixes to the reamaining codes. just depends on the ones your getting. give me a ring we can go through them
