I am looking at getting the Valve Body Mod and an upgraded ECU. My question is, do I need a different ECU for the Valve Body Modification? I thought I better ask before I go and bye the wrong one.

And, for those that have both...which would you do first? The Valve Body Mod ($450) or the JWT ECU ($595)?

 

i have the JWT TRANNY ECU for sale if your intersted.
asking $425 for it. Ill install it if your local. More info can be found on Cattman's site or JWT's site.

 

what different ECU's does JWT offer and how do they differ? Is the Tranny one a good one? If you couldn't tell, I'm clueless about all of this

 

ok, I read Cattman's info. I want to get as much performance out of my Maxima as possible. Does the performance ECU get more gains than the Tranny ECU?

 

If you want max performance out of your tranny..i.e: you want it to operate almost as fast as a 5 speed get a vb mod and a high stall converter.
