I have an LS2 with a LSA supercharger, I was running it with an E38 ECM but recently switched to a E67 ECM so I could take advantage of all the support it offers
for the supercharger, the harness and ECM came from BP Automotive, I'm running a GM TKO600 and the VSS seems to not work with the new ECM, worked fine with the E38 ECM I set all the parameters to be like the E38 but for some reason I get a P0502 SES code. I've searched the WEB but only find stuff on the GM connect and cruise setups with T56 magnums, which mentions GM not supporting the VSS in the OP system loaded into those E67's? I've attached my tune file.
Any ideas? Thanks guys.
