Following the successful release of ProECU Nissan 370Z RaceROM Phase 2, EcuTek have developed FastFlash.
FastFlash speeds up the programming sequence significantly. No more hanging about wasting precious time, FastFlash programs the ECU in as little as 20 seconds*.
Don't just take our word for it, check out the video!
To have FastFlash enabled on your copy of ProECU, simply run EcuTek Update and download the latest version of ProECU for 370Z. You will also need to ensure that the latest RaceROM Phase 2 feature file is programmed into the ECU.
*The first programming sequence will be longer, but subsequent programming sequences will be this fast. Not all ECU's are supported with Fast Flash due to the capacity of the ROM.
