Hi spfautsch,

Is there any recent firmware to test. I want to use latest and greatest. I am trying to figure some weird fueling issues and want to rule out any spark issues[The car does feel a bit like a spark retarded] and AFR drops from time to time to 13.8-14. It is really intermitten. Once works great[rock solid afr at 14.8-15.2], than after some heat soak it runs like crap and AFR jumps like crap. I suspect a bad injector but might be some coil issue too[].
