#275, "RE: ATTN: MrSlick Megasquirt question" In response to In response to 2
Howdy,
To answer your questions:
I was running a narrow band with the old setup... but as pointed out my new engine will be using a techedge wideband... yay. The switchover point should be set to 0.5v for narrow band. The reason being is that where stoich is at on a narrow band... when in closed loop you want to swing either side of that value... just like the stock ecu does. As for the ignition steps numbers I don't remember off hand. I'll tell you this though... those numbers are the leassst of your concern.
You will have most trouble finding a good rpm signal, and getting the accell enrichments set good.
For the ignition trigger if you do not modify the MS (I'll tell you how later) then you must use one of the two coil pack trigger wires for the rpm tap. This then means that you have to tell the MS that the motor is a 2 cylinder...
