No, this is not the notorious ECU upgrade, and no it's not the Venom PCM in another name. It adjusts ignition and air/fuel curves. I posted this in the general forum because it is all apparently for all '84-'01 Nissan 6-cyl engines. Has anyone tried this? Please don't tell me it's crap unless you have used it or have information to support that. I know JET has not made the best name in the Maxima world, but for all we know this could be a worthwhile product.

Here is the link.

sounds similiar to the apexi-afc?

 

I don't think it's quite that adjustable... actually I think the piggy-back unit changes the curves and ratios itself, but I could be wrong, especially since there is a **** or two on it.

I still question that company. For one how could they list it for all the maximas? There are many ecu/ignition/fuel variations thoughtout this application.

Installation: "easy underhood connections" This indicates that they are accessing the maf/tps/rpm. Although you can tap into these sensors for readouts and maybe you can fool the ecu though changing the maf/tps voltages, I highly question how just "fooling" these sensors can result in the "optimization" of the ignition/fuel curves. The only precise way to alter fuel/ignition(especially this one) is by accessing the ecu itself. And that means breaking the code for all the maxima ecus thoughout the years/model lines. JWT hasn't been able to do that.

 

Welcome to 1972! the V-force is more than 2 years old! I know a guy with one on his Civic....minimal gains (just like the AFC and advanced timing combo) on NA cars!

 

Well... that ruined it. Thanks for the info though.

and like Jeff said the usual vague and "it will work on any Maxima" directions makes it even more iffy! and how woud this thing allow for ignition timing adjustments on the VQ??? I seriously doubt the claims....
