$1,000.00 USD
Gen 3 Viper Prefix ECU. Fits 2003 - 2006 Vipers. Full ECU with Prefix Flash on it. Keep your factory ECU. Call or email us after you order with your cars information so we can process your order. No core, keep your current ECU.
The new ECU is available and will be more robust to allow owners to run most typical racing modifications without limp-outs or MIL’s. This flash is intended for off-road use only and will have the following changes/improvements compared to the previous Mopar off-road controller:
-
Improved throttle response and feel and a more aggressive pedal map
-
Misfire monitor disabled which will allow use of other engine and driveline changes without false misfire detection
-
Airflow rationality monitor disabled which will allow changes to air cleaners, ducts and filters, hood scoop and other inlet side modifications without limp-out
-
Temperature rationality disabled to prevent MIL’s due to changes to the cooling system, oil cooler or oiling system
-
Leak detection system disabled to allow use of fuel cells without LDP MIL’s
-
Rev limit increased to 6600 rpm for track use
-
More aggressive exhaust note on deceleration (i.e. popping)
