Not the BCM Dale and not with GM software. I can tell the ABS we have bigger tires but it won't change the engine and trans stuff as the VSS goes to the PCM before it relays the info to the EBCM and the IPC. Service Brake System means something different than an ABS light or Service ABS message. If I can make it out to the dyno day I'll bring a CANDi and a TechII.....as well as my POS MTD leaf blower that seems to have no spark. I need help as well....
