Q. Does the ECU+ require an EPROM ECU?
A. No. It works with any DSM or Evo VIII ECU.
Q. Does the ECU+ have a warranty?
A. It has a one-year hardware warranty against manufacturer defect. There is not warranty expressed or implied on the software, nor on any suitability of the ECU+ to do what you want it to do. Neither is there any guarantee that you won't hurt your car using it. The nature of any tuning device is that it CAN damage your car if not used with care. Proceed at your own risk.
