ProCom ECU for rzr

Well for christmas, I bought my dad a ProCom ECU for his rzr. It is the programmable one.
So far I have only tried the map for stock motor and beginners from procom. It does seems to run harder, only issue is there is a stumble when you first punch the throttle from a stop. Trying to fix this. I have downloaded all maps for stock motors from procom already. I have even created my own fuel and timing map but have not seen how it works yet.
I am going to maybe install my map soon, put in some premo fuel and hope it works.
With the other maps, I have no raised the rev limiter yet, but on my custom settings, I raised it 500rpms.
I am really waiting for my wideband sensor to come in so I know if i am running lean or not.


But just wanted to thank Wildcard Racing for getting me this ECU.
Thanks Brandon and Shay.

Any new information on this?

still messing with it. i installed the map i created for it and it seems to like it. really need to put the wideband sensor on it and play with it some more
