MAF parameter question

[67ragtp]

Im getting ready to fire my ls7 and the ECU was initially prepared with parameters to run an LS2 MAF. I installed a blade LS7 MAF and also had to change the harness connector pin configuration, If I fire the engine will it idle, Im just not sure how much the ls2 parameters will effet the fueling?
Engine has never been fired so I would like to know what to expect, Dont own a copy of hp tuners so IM stuck. Any clue?
Thanks Rich
