ABS and Servic Brake System light

[randyc]

I know what you are sayin', but sure would like to get what I already paid for sorted out before I pay more for a custom tune.

it went farther and I thought today was the day, but at about 15 minutes they came back. I did hook up the GPS and speedo was within 1 mph (or less).......................left everything alone just like you said

post a copy of the last tune written please....and the backup.

[randyc]

will do,
Thanks

[randyc]

Here you go

[randyc]

Mike, I did not notice both of these files do not seem to be updated since the you had me apply the fix.

[randyc]

were these incorrect nd of no use?

[randyc]

bump

[randyc]

Mike,
I re-loaded copies of my backup files 2 weeks ago as you asked................................any progress????

[mikel]

the LTW showed some changes that seem to have been applied by the parameters.

load this custom tune, and when the tool asks if you want to reset params, choose yes, then dont make any changes.


Thanks

[randyc]

I will give it a shot and report back with what happens.
Thanks again!

[randyc]

failed again! Did as you said, loaded, said yes, did not adjust anything......
Should I re-try just doing the ECM? (leave the tranny on stock)?

Mike, I know you are trying and I will do whatever I can to help........................one question, if we never get this sorted out, will I have recourse?

[mikel]

I'll have a new update for the tool to correct this soon, lets just hold out for that

[randyc]

will do......................just lmk when, thanks

I would like to know if this has been resolved as I am having the same issue with my 07 new body style silverado with an intune and larger tires.
I found this on another forum, perhaps it may help.

I loaded a superchips tune with the adjusted tire size and gear ratio on my truck and read it with hptuners. I copied my current tune to the superchips file but left their speedo correction alone. The values under speedo are all the same except the general vss pulses per mile. When Superchips does the speedo correction I get a ppm value of 128458 and I also get NO ABS light or parking brake light. With Hptuners, my ppm value was 103585 and I was getting the abs and parking brake light on everytime I drove the car. Anyhow, I found this quite interesting. I have had the larger value in for ppm and I have yet to hear the dreaded chime.
