Anyone try both of these?
I may have the opportunity to do just that.
I am to get the UPRD by the end of the month, Soon as I get my Max out of the shop.

Does anyone know how the Underdrive pulley will work
with a Mod ECU?
Will the ECU need to be programed for this?

Thanks, E

 

I've got firsthand experience with the JWT ECU on a non turbo 300ZX; the programming is similar to the Maxima ECU. Advanced timing along with modified fuel maps in open loop and a higher rev limiter. The JWT ECU is worth about .2 seconds and 2 mph at the track.

There is no conflict between the pulley & the EPROM reprogramming.

 

Phuong, Thanks for the reply, E
