Got my car back today. They had to reflash back to stock, because the 'revert' that the ProCal does back to stock doesn't do everything, according to the service manager.
I mentioned that the 'revert' listed 15 params that were changed. He states that there are many 'untouched' that are changed with the tune, but not 'backed out.' Learned a couple of other things:
- The 'crank relearn' does not have to be done, when flashing the FRPP tune. It is incorporated in the tune, automatically.
- After the tune, the 'relearn' won't work (according to him).
- He's seen some 'pinging' with Shell gas lately, due to the amount of alcohol - he states "other than Shell gas" should be used. YMMV, this applies, perhaps, to my area in TX. Dunno. I know that I've tried a tank or two with "other than Shell gas" and it still pinged - but differently - as to amounts and where in the band between 3800-4000 and near-redline. It was all over the map, as to consistency. Sometimes, barely at all.
Take all this with a grain of salt. I'll get more info from their 'ace' Stang guy when time permits.
The low-end is more 'anemic' now (like it was before the tune), and when I 'reverted' back to stock with the ProCal it's clear that it left "some" low-end untouched in the revert.
I'll leave it alone for now, as the diags/test/reflash to totally stock ran me $89. I didn't argue, it's not a warranty procedure.
