After putting a Bodis on my 2010 and augmenting FI with Bazzaz ZFI/AFM, I've started having a little issue. For a short while after starting cold, if I ride a short bit, and go to stop - the engine cuts out. This wasn't present before the Bazzaz. It seems to me fuel starvation, but I can't figure out why. Once it gets up to normal temp, non-issue (pulses a bit sometimes for a few seconds.) Any ideas?

Did you have your biked tuned by a good tuner to build a custom map for your bike utilizing the bazzaz fi management? If you relied on the base map that was sent with the unit that will not work. I have a 2012 f4 with mv coarse headers, bodis ti slip on and z fi plus quick shifter and it runs flawlessly with correction of the fuel map curve going straight up and the air to fuel ratio inline with what it should be. All that was possible due to the custom map built and not just plug and play. Also if you have the quick shifter option built in check the settings on each up shift gear as that could be off. Had to call bazzaz and get the baseline settings from that then tweak it to my riding style for quick shifts.

No good tuners in the area (Closest I'd trust is Ferraccis in Willow Grove, and schedule just doesn't allow for running down for it right now) , and I'm trying to book some dyno time near-by. I've done tuning on Microtecs for my Duc's, but this is my first "piggy-back" module. Not using the base map. I bought the AFM module knowing I was not going to be able to do a proper dyno mapping for immediate effect. And frankly its worked rather well. In fact this really is the only issue I've had since install, just a bit perplexed. It's the only thing I can't square out.

Cool deal, check your idle times and that can be an issue and it is programmable and if you pm me your map I can compare and send you mine. I know out bikes is 2 years apart but I believe all is the same maybe the corsacata motor was introduced in mine so may need to check. Other than that we have the same setup. Let me know if I can be of help.

Thanks. Will do. I do think the idle is a bit low when cold. Seems normal when warm.

As mentioned, this is my first piggy-back. Wanted to try it as I wanted to get the Bodis on and riding ASAP. Honestly I think I might eventually trade out for a Microtec though. :)

For the record - (and for good or bad :) ) I'm an insatiable tinkerer. I can't leave things well enough alone. I like to know how things tick, even when there's nothing wrong. Yes, I've already tore into the engine some just to see how MV did things.

I believe the new motor started on the F4rr 2012 and the F4r 2012. I had a 2010 f4 which was the older motor.

SpainF4, that problem is way worse than mine. Sorry to hear it. Mine ended up being a loosened retainer nut and idle out of adjustment slightly. I hope an answer for yours is rapidly forthcoming. Personally I would suspect a clogged fuel filter. I've seen that behavior in the past with clogged fuel filters.
