LS9 E85 hot start issues, can someone look at this tune.

[99z51r]

Just wondering if someone can look at my tune, I've been having my ZR1 remotely tuned and everything is good except if I try and start it anytime after its been running it usually takes 2 times to get it started cranks for 5-6 sec. then when it starts it stumbles badly for another 5-6 secs. sounds like it running on 4 cylinders, then cleans out. LS9 with 2.6 pulley, snout, CAI, ID1050x injectors, flex fuel kit. I have hp tuners but I haven't done much tuning myself. I've pulled the injectors to make sure they weren't leaking. Thanks.

I know this is old, but did you ever figure out what the issue was? I?m running similar mods and having a similar issue but only when engine is cold.

cranking fuel tab the cold start area (far right it uses engine off time) just double the value and blend a couple rows back in and see if it helps, also not too much cranking timing maby 5-10 deg when cold see if it helps, for hot starts just see what it needs as it should fire right up just like petrol
