for those running the flexfuel chip, I have added another feature to the software. I haven't tested it with the earlier SD2, but the boost solenoid and fuel-cutting will likely work ok.
Its *** Overboost Protection ***
what it does: it will turn on the check engine light and shut off the boost solenoid when an overboost is detected, and optionally, shut the motor off (DO NOT USE THIS WITH ALKY)
the feature resets when you drop the throttle.
Its a free software download. Attached below, and I'm sure TurboTweak will have it on their site soon. When you run PLC, it will drop PL044.s19 in your powerlogger folder. update your PL with this file and you are good to go (save a copy of your tune before doing this..)
The immediate threshold triggers "immediately", the delayed threshold will wait the delay time before triggering. For turning on the SES light and turning off the boost solenoid only, this is all you need to do. If you want the PL to cut fuel (not for use with alky, E85 is fine though), add 8 to your options total, and put it in the options box.
