RESCALE TUNE for Pump Gasoline
Only available for pump gasoline. Not available for E85 or Race gas.
Every Rescale Tune is setup for each customer’s individual needs. A “Rescale” tune is very basic tune but is MANDATORY whenever major components are added to the vehicle. A properly configured Rescale tune will allow the engine to start and drive normally at idle and part throttle. WOT will be safe but most often not be ideal.
NOTE: You must purchase a Rescale Tune BEFORE the following parts are installed:
3bar or 4bar MAP and TIP Sensors
Any size injectors other than what the PCM was originally calibrated for
1:1 Return Line Regulator
Aftermarket Cams
Aftermarket Wastegate Actuators with PCM Boost
Larger turbo than Stock
Annoying CEL (Check Engine Light; WILL NOT PASS EMISSIONS TESTING!)
Long Tube Headers
We don't even bother messing with your lackluster "Canned" tune but start fresh off the customer’s Original Backup tune. Then we add the following performance improvements:
Modified WOT Timing table based on Turbo, PCM, Octane; Scaled up to 3bar
Modified Part Throttle Timing for improved idle and drivability
Modified VE Table not only for improved idle and drivability but to also add progressively fuel with boost up to 3bar
Raised Charging voltage to increased fuel pump supply and coil output
Enable WG Adaptive Learning to allow PCM to adapt for changing conditions
Modified Waste Gate Duty Cycle table based on the wga used
Modified Desired Torque {“Boost”} to improve boost control
All Torque limiters, raised or disabled
Cat Over Temp disabled [aka COT]: provides more stable WOT A/F
Boost Cut limit raised but left active to provide proper Fail Safe
Modified Knock Thresholds to prevent PCM from needlessly pulling timing
Cooling Fans On Temp lowered
PCM Knock adjust A/F FAIL SAFE!!!---PCM will automatically richen up the A/F the INSTANT it sees Knock. As soon as the Knock subsides, the commanded A/F returns to its original setting
