    2009 silverado V6 to V8 swap....ABS C0245 SES code

    We are working on a customers 2009 Silverado which they had the stock 4.3 V6 and A4 tranny swapped with a crate v8/beefier A4. Apparently they couldn't get it to run so now it is our problem..... We installed an E38 PCM and are starting with a 2007 Silverado 5.3 tune. PCM OS is 12614088. We have rewired a bit including the VSS signal to pin 57 of the PCM. All seems to be coming together but we are getting a pesky ABS C0245 DTC code. Tech 2 shows the Front VSS is 31mph and the Rear VSS is 20mph which trips the light.

    The 2007 doesn't support a Tech 2 reprogram of the ABS modole for tire size and I am struggling with getting the Front/Rear mph the same and the speedometer calibrated. I have read several threads on other sites that say we may be sol and need to pull the bulb....I hope that isn't true.

    Any help would be approciated. Not that well versed in segment swapping if that is required.

    Thanks

    2004 Corvette Coupe, LS2 Shortblock, MN6, Vararam, American Racing Headers/CATs, Magnaflow, 4:10's, Trickflow 215 Heads, 30# SVO, Vette Doctors Cam, Fast 90/90, Performance Clutch, DTE Brace, Hurst shifter, Bilsteins etc.....480 rwhp and 430 rwtq

    old setup -- 11.9 @120 mph with a 1.8 60' is best to date
    signature setup -- TBD

    interestingly it seems that one vss may be in mph and the other in kph......or is it just a coincidence? Sitting in an airport, will have to look into this when I get home......
