Hi all,
I have a data log from the drag strip. I see a goofy drop out in my injector signal. The scary thing is, I can see the AFR return a lean spike so its real but why. This is not good at all, I need to get knock set up to see if it would retard. I have v3.57 MS2 extra 2.0.1 (i know its old) running 95lb/hr injectors on the fly back. Also what it Bit 8, it flashes yes some times in the data log. Scared to throttle my car but its soo fun its hard not to.
Any ideas? Thanks!

It's really hard to tell anything without an .msq file - we have no way of knowing what your settings are!
But here's something to check: go into acceleration wizard and look at "decel fuel amount". If it's not 100, try setting it to 100 and see if that helps.

Well I looked at the msq and the log and I can't see anything else that would cause what you're seeing. Try setting the decel fuel to 100 and see if that fixes it.
