MSII v3 - Running wideband, wierd Lambda readings

richiea · Post by **richiea** » Mon May 01, 2006 8:16 pm

Hi guys, I've got an LC1 and just started running the car with megatune (less than 15 minutes running so far). I programmed the LC1 to stock settings, narrowband analog out going to original ECU (controlling spark) and wideband analog out going to megasquirt. In the configurator, I have selected innovate LC1 from the list. When the car runs I see values anywhere from 0.1 to 1.35... How do I get megatune to display these results in AFR i.e 14.3:1 12:1 etc... Is the only way to just do the old 1-2v and 10:1-20:1 AFR output trick?

(Excuse the fact I haven't experimented enough, all the time I had to spend tuning was spent trying to figure out how to program the stepper IACV, of which I ended up giving up on as the algorithims seem to make no sense. After logging on this forum, I realized I'm not the only one. I suppose I'll give it one more shot and until then it'll be easier to just go to back to an ICV)

Thanks for the help!

Don't forget to run Tools; Calibrate AFR

Set it to: Innovate LC1 0-5

As far as I understand it you must reprogram the stock LC1 to output 0-5 volts for 10-20 AFR for whatever output your using. Just run the programmer that came with it.

If you want Megatune to display AFR you need to set that in the configurator I believe.
