Quick FICM Calibration question
I currently have the ECM strategy of VXCF4NK. I'm pretty sure that is a decent one so I'm not really that interested in changing it; however, my SCT pulls a 3rd number when pulling strategies: ARZ2AL01. Is this the FICM calibration, and if so, is it a decent one? I had my truck at the dealership a couple of years ago for an issue and of course they flashed it without telling me. When I pulled the strategy at that time it showed me VXCF7 something or other. I returned the truck to stock again using the SCT and ever since then it's shown the same VXCF4NK/TQCI1N2. My concern is that since they flashed it to the later strategy I'm sure the FICM was bumped as well.
I just want to make sure if this is a decent or sucky flash. If it's worth it I wouldnt mind doing the rollback to save the FICM. So far it's still got good voltage with no injector codes up. Thanks for any help you can give me.
