Hi im a little confused about this ECM??

In Tuner Pro are diferent masks available, i try all them out, best i think was 61v3.xdf?
when i use 61V2.xdf and compare with the original bin (ANTT) there is Distributor Base Timing set to 11.25
if i open the same Parameter with 61V3 the same Parameter is set to 2512.0????
Factory base Timing labeld in the Hood of the camaro is 0°BTC?

Any body out ther who can help me?

im also searching for the Parameters that controll the Crap Smog Pump !! In Austria its necessary to pass the Smog Tests

I have put out the 305 TBI and hoked up a 98 350 Vortec with TBI Intake and a mild Cam
Ve and Sparc Tables are adapted from an Vortec Engine, Iddle is incrteased to 700RPM


if anybody has done equal works like that, im open for good Idears

Regards Andy
