I'm noticing a strange issue with the wideband input affecting the injector pulse width. I don't have EGO correction enabled so that's not affecting the PW. I'm using a Spartan2 wideband that has a startup sequence where it will output 1.33 volts for 15 seconds and then 3.33 volts for another 15 before it begins output the correct AFR.
I'm noticing that upon start up, the PW seems to be changing with the voltage. I'll be reading 1.8ms while the wideband is outputting 1.33v and then as soon as it changes to 3.33v, the PW jumps up to 2.1ms. As soon as the start up sequence ends, the PW drops another .3ms.
This is with the latest firmware on a UA4C board.
