Thread: IAC goes high, when is Learning done?

    The great thing about a Sniper is that it is easy to try different AFR values. You just type the new number into the table and then see how the engine runs. Or you can play directly with the Base Fuel Table if you have a laptop hooked up.

    Controlling the ignition timing would be good, but in your case you might have to make your own distributor. Take a factory distributor and hollow it out and then add a Hall-Effect pickup assembly from a HyperSpark.

    I can easily use a crank angle sensor from a later year RX-7 instead of the distributor. The problem with the Sniper as far as I know, is that it can't control leading & trailing split timing. Other EFI setups like my Wolf V550 have the ability to separately control leading & trailing spark. But in the case of this car, I was only assuming it would be fuel only for the EFI. I'll give the AFR adjustments a try and see how it goes. Thanks for the input!
