Wtb 496 Ho Pcm/ecu?

I'm trying to avoid having to pay full retail on one of these things. I emailed WHIPPLE to ask them if the VE Tables in the PCM were any different between the HO & regular MAG (375hp) but haven't heard back yet. I'm assuming the tune is different since the pn#'s are.

UPDATE from Dustin @ Whipple. In addition to the VE tables the spark, idle & knock are also different.

My choices right now

1) Whipple retune $800
2) Purchase from Mercuriser Parts $1,200
3) Or get a used one. (doubtful) since there are nor CARB conversions for the 496MAG yet, right?

I can offer you a price break on a new PCM. Shoot me an email. [email protected]

I have also tried to email them about the stage two kit for the 496 ho, which involves an ecm modification. No response... I guess I'll just call them.

saubouin- You should check into one of their kits. It might be what you're looking for without spending a fortune.
