95-96 ECU put into a 98???
I know you can put a 95-96 ECU in a 97 (with a CEL), but has any member on the board succesfully put an ECU in their 98 Maxima?
Searching back through post I know Madigrass did, but that was after he put a 96 engine in I think?
Also, I saw some rewiring instructions somewhere before for the harness, but can't seem to find them anymore.
My mission is to get a VI, but without an ECU with a higher rev limiter it will be almost pointless

about the ECU question...i think you would have trouble with your 1998 digital odometer with a 95/96 ECU and other things as well.

I just need to find a list of what exactly is different between the 95-96 ECU's and the 97-98 ECU's.

The 99/99 Maxima ECUs do not store the mileage to the odometer in its memory. I confirmed this when I got my hands on a 99 SE gauge cluster. I hooked up two (2) of the many wires on the back of it, and I hooked up the ground wire, and the odometer came on. It showed 38647 on the odometer. This proves that the ECU does not monitor/control mileage.
Also, I got my hands on a bad cluster as well. I took it apart and compared the unit to my 96 cluster. The 98/99 clusters have a "RAM" chip located behind the Speedo gauge right under the gauge face. So this also proves the mileage is recorded in the actual cluster itself......
Also (2), I have sold two digital clusters, one to Co_Maxima98, I think that is how you spell it. Well, that cluster had 58k on it, and when he plugged it into his car, it did not read out his actual mileage on the old cluster. It read out what the new cluster he got from me had on it.

The 96 worked fine in my car except for a CEL, I got a gode for EVAP IIRC? Their is supposed to be a way to rewire, I thought Cheston knew, but he never replies to my e-mails about it, so I guess he doesnt?

NICE!! And isn't that the same code that the 97's throw? Or maybe that was a rear 02 thing?
Another concern I have is that when I go to do emission they hook some wire up to my car to test it instead of putting a pole in the tail pipe? A 96 ECU may provent that?

You will need to swap back for emissions testing.

That and I need to start searching for a 95-96 ECU lol

It's the opposite, the 95-96 show more gains than 97. That's always been the rumor anyways, I've never seen it verified with empirical data.

I think Cheston lost hp when he put a stock 95-96 ecu in his 97, but with it modded he still got more hp out if it than his stock ecu, it was just not as much as it would have been in a 95-96 car. does that make sense?

lolI need to look back and see how much hp Cheston lost. This mod might take me awhile because I want to do testing along the way to see what gains I am actually getting. Like buy the 96 ECU and run with it at the track to see if I lose anything before I send it to JWT?
