Hypertech PowerProgrammer III - Help? :) When it comes to car tech, I'm a bit of an FNG, but let me know what you think...
I just got my wife an '02 Firehawk. Previous owner had a hypertech programmer, used it once and "married" it to the hawk's vin, and then messed with (or paid someone to mess with) LS1Edit and changed some not-so minor details (edited # of O2 sensors, i believe) and now the programmer does not work, gives an "invalid stock" code. I'm thinking about getting the ecm reflashed at a dealership. I figure that should correct the "invalid stock" problem, but I also know that the programmer looks for a tune on start-up and if that tune is gone, due to the reflash, will that cause a different error with the programmer? Or is it possible to have the programmer reset?
Any insight would be greatly appreciated.. Thanks!

If the previous owner did not uninstall the HPP3
programming before tuning my guess is it won't
work-although I can't understand why anyone
with tuning capability would make additions
to changes made w/HPP3.
If you flash back to stock in this case, you can
send the unit to Hypertech and they may fix you up
(for a fee) if you explain the circumstances.
Best to call them and see if you can talk to
someone you can get some sense out of.
HPP3 is somewhat ok for A4 shiftpoints, rev limiter,
adjusting for a gear change, fan turn on temps.
I had lots of knock retard with their performance
programming.

yeah, I called hypertech and have also been email corresponding with them and it looks like the best bet is to have the hawk reflashed. I really don't understand why the guy would have HPP3'ed it and then went in with ls1edit later.. maybe he thought he'd never sell it.. either way I'll just be glad to have it back to factory settings, where I'll atleast know where to start.
