ECU blues.......has anyone else had these symptoms?
I just put the JWT ECU on my max today. As soon as i took it for a spin i noticed that it was a little more balzy than usual. But as i drove on, the car started to hesitate REAL BAD and the rpm's started to jump up and down. I would let off the gas for a while, and then step on it again, and then it would be ok. then i started to drive some more and it stated to do it again, at different parts of the power band. I was like WTF!!!! I took it back to Stillen and they said that it's a learning computer (this i know), and they said it has to relearn parts of the power band all over again.
Well, i drove it home and it still does it; just not as bad as when i first drove it. So i ask you guys, has any of this happened to you when you guys upgraded your ECU on your Automatic maximas?

as far as mods go, i have lots of custom stuff in addition to every bolt on, except the ECU is $600 i just dont have at the moment.
dont take this the wrong way, i'm just joking around with ya, unless of course you're willing to actually buy me an ECU.
edit: bring the ECU back to stillen and ask them why its not running correctly. they SHOULD have a warrenty and i'm sure they wont have a problem taking a little extra time to figure out the problem. they call it customer service, if they dont agree then ask to speak to the manager, and eventually steve himself..haha

that's actually what I was trying to do on Fri. when I bought the dam thing. They told me to just drive it over the weekend and it would get better. Now it's actually the opposite, it just gets worse and worse. Between sputtering down the road, to stalling at stoplights (how do you stall in an automatic?

its very obviuos the ECU they gave you is bad and causing the hesitation it has nothing to do with your max rejecting it, if anything it would reject your max
take it back and see if they can reprogram your current ECU since you know its good
