I have installed 20+ of these boards now, all where fine.

Issue is installation, if someone doesnt really know how to solder properly then it should be left to the pro’s.

Usually what happens is the traces get burned or contact pads get f’ed up.

A proper ecu tune, cannot be touched to its reliability and consistency.

Cost wise, board is around 300, but unless you plan on tuning it yourself you do not have to buy the software as i have a tuner license of nistune.

Let me know if you have any other ecu tuning questions.

GL.
