Tricky-Ricky Posted December 10, 2012 Share Posted December 10, 2012 I don't think Greddy made a wide-band gauge/sensor, only narrow-band, how many wires does the sensor have if its not five then its not wide-band. Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted December 10, 2012 Share Posted December 10, 2012 would a wideband o2 not be used with the e-manage to cotrol the a/f ratio then? As i said before you can use a genuine wide-band gauge/sensor to input the signal into the EMU, however the self tune function of the EMU is not good, its only really useful for data logging whats going on.

Tricky-Ricky Posted December 10, 2012 Share Posted December 10, 2012 I'm afraid i was right about the Greddy AF gauge being narrow-band only, found you a manual here, http://www.greddy.com/upload/file/AFwarning.pdf i. sorry to say that apart from something to look at that gauge is next to useless.

In a word you can't, the MAP sensor is used to scale the engine load v RPM, AFRs are what you used to ascertain the correct fueling for whatever load/RPM, I'm afraid there is a lot more to it than that simplified version.

buster Posted December 10, 2012 Author Share Posted December 10, 2012 so how do i get the corect ratio using my emu would the guy mapping it sort that? This is all very intresting Link to comment Share on other sites More sharing options...
