Emissions test w/SVT tune?
Hey Tom (or anyone who might know) -
Do most folks with the SVT tune have to go back to stock to pass emissions tests?
I had my car off the road for a while, and now I can't get it to pass the OBD readiness checks. The Diablosport shows no actual check engine codes, but I've driven nearly 1000 miles and the shop still gets readiness check fails on Evap, O2 sens, and O2 sens heater.
I did have the master P1000 code when I first ran the car, but that has cleared.
Trying to avoid reprogrramming twice, especially since I have to get the tune file from Tom to go back in the Diablosport (my laptop with the file died over a year ago).
I've never had to flash the ECU back to stock here in Illinois. As long as that CEL doesn't come on when you have the performance tune in there, you should be able to pass emissions.
BTW.... All OBD-II and newer cars here in Illinois just get checked through the OBD port.
The PC does not hold your stock file the Predator does , I can email you your Custom Tune any time
Most dont have any issues passing , clear your batt , drive a day or so and try again , make sure your o2 is working properly with the logging the pred can do
