Re: Pcm re-flash
WCV PCM idle hang update. Talked to John at WCV for awhile today (he is super-Viper tech BTW) and he is of the mind that idle hang is greatly influenced by throttle body synchronization. I told him about how I adjusted the t-bodies and went for test drives. He pointed out that I was following a faulty procedure: 1) the throttle bodies cannot be synch'd manually, only electronically using what he called a DRB diagnostic procedure that uses the available electronic sensors to determine the amount of air making it past the t-body blades at idle; and 2) each time you make an adjustment, you have to de-power the PCM for a full ten minutes so that it will take a brand new look at the re-synch'd t-bodies and make its idle hang decisions from the new baseline.
