I was watching one of those car performance shows on TNN and they hooked up a comptuer into the diagnotic port of this minivan and were able to cahnge gear ratios and all sorts of cool stuff. Do we have a diag port on the Max, and is there a computer like this (it was a small handheld thing)? If so anyone use it?

 

I don't think so... unless you have a CVT.

The ports will only give you error codes and what the sensors read... kinda like a OBDII reader and TECHTOM

 

Dude I was just about to start this same thread. It was HorsepowerTV. They put a Borla catback and a K&N panel filter in an Astro Van . Anyways, they got 17hp at the wheels, but they hooked into and 'reprogrammed' the computer using a device that asked yes and no performance questions. I was wondering if this is something we should be doing?

 

yeah, i watched that same thing on tv.lol. i just posted about it in the 3rd gen forum. anyways, i would rather have that than have to take my ecu out and send it to jwt to get overcharged and have pretty much the same thing done. i looked in the summit racing catalog and they do have some of the reprogramers. they are only like $300 for them, but they didnt have any listed for maximas. they only had ones for GM and Fords .

 

yeah they were changing auto trans shift points, not gear ratios. It would be nice if the max had that functionality.

 

Im glad im not the only kid who goes to his girlfriends house and watches car shows =). heheh. So we cant do this with out maxs?
