frequent failuer of cooling system and AC after flashing

I had the same issue again with two cars today, any help please...

I don't play with abnormal stuff, I mean I alter fuel, timing,...etc. This problem started with me since using this build 156. Before I had no problem.

Thanks,

Do you think running the new update "August candidate 2" will eliminate the issue???

I would certainly give that a shot.
Are you updating the V2 firmware with each update as well?

sure I do update the firmware

I'm sorry I don't know what to do for you. That's not to say we've given up, we just don't know what to do.

I got the 2010 camaro to work today with a flash and i noticed the ac was blowing colder out the passenger side and the driver side was hot almost like ambient air temp, i asked the customer and the car has always done that so it isn't tune related, i asked around and have heard of other gm models exhibiting the same issue there are a couple of air temp motors and air blend motors that can cause this not to mention if it has auto climate control those are notorious for going out.

I called up one of those customers who have the issue, hopefully he passes by me soon to test the update on his car.....

the issue is still there with the new update, please help I am losing customers

odd boy,

do you have V7/V8 build 178/168 and firmware 2.07.21 from here: Release-Candidate-2-Aug-19-2011

We've not had any similar things mentioned so we're thinking there there is a potential that the file your flashing may have been corrupted by an older V7 software release. Do you have an old calibration file for the vehicle that you'd be able to modify using the latest V7 software release and flash? Or perhaps even a stock file for the car?
