nemu uses TCD bro, not bin.

btw that's also my FC whatever ECU i'll use, (16ve ecu, 20ve ecu, NEMU)

I think we got him sorted out for the most part.

His O2 was giving back some false info and the short term fuel trims were basically maxed out at 25% the whole time while in closed loop.. that definitely won't help your gas mileage!

John thanks for all the help and patience...going to have wideband reading and tuning if it permits on Saturday...

ExaltaVE is happy with the NEMU now hehehe
