95 vs 97 ECU
why does the 97 ECU suck compared to the 95...my moms 95 revs so much faster and the speed limiter crap isnt there..why does nissan have to do this..make the car look nicer but run worse...das gay...can u swap a 95 ECU to a 97??

now here's the answer: let's say that both cars are identical cars other than model year and the changes that came along. same mileage, same service schedule, same tires and wheels, same everything. the 97 is heavier and has more OBD II (emmisions) restrictions.
that's a simplistic answer. the real answer can be one of millions. dirty throttle body, dirty fuel/oil filters, different gas, different tires, different wheels, different models (GXE vs GLE, etc), different mileages, different throttle cable tensions... a billion different things.

I have a 97 SE and it does not have a speed limiter..just like sprint said. it may be hard to get past the 120/125 mph mark, but if it is a SE there is not a limiter.

If you have a 97SE and find it hard to get past 120 mph, then that car needs maintenance, ESPECIALLY the fuel filter. Get it replaced.

B) your car is not an SE
SE's never came with Speed Limiters

Does it shut off, or just kinda lose it's breath, so to speak?? If I were you, I'd do the maintenace 1st before I go the ECU route. It's cheaper that way, too.

.. well i am not sure if the ECU has the VIN on it.. if it does.. you can check in the FAQ's above.. it it will tell you if that VIN is SE or GXE if everything checks out right.. then it might be a production F'ck up.. someone had one too many beers

Yep that was me. Ever since I talked to you at island drag I have been thinking that I probally have some kind of manufacturer defect. I am going to check my 97 ECU and will let you know what I find. I think your right that somebody had one to many beers when they were building my car

For those who don't know, all Maximas that are not SE's with the Security and Convenience Package have limiters. The Security and Convenience package included "H" rated tires. All other cars had "S" rated tires. This probably seems strange. S&C SE's can obviously go faster than their "H" rated tires are rated for. It would have made sense if they used "v" or higher rated tires. What was Nissan thinking?

The limiter isn't set by years, only by the equipment on the car. As far as the 95's are faster than 97's, this is a false. There are definitely production differences bewteen cars. Some are stronger than others. My 97' ran a 15.210 @ 92 100% stock with only 3 runs all night. I didn't even get to work on the launch or shift points. Andi's 98'(now Paul's) only ran a 15.9 stock. I had extensive discussion with JWT about this. From what they looked at, the maps are essentually the same. The differences are in the 3rd O2 sensor readings and the diagnostic information. Robert(Biomax) dynoed his car with both a 95' and a 97' ECU and there was no difference.
Keep in mind the self learning in the computer will also make a big difference in how the car feels. Try clearing the self-learning and see if performance improves.

no its not false.. the 95 maxima is the fastest of all 4th Gen's.. its lighter.. and it has less emmision restrictions.. if you think 15.2 stock is impressive.. you obviously havn't seen VeeTec or Neal's stock numbers.. 14.7 and 14.8 respectively

Nissan did that to keep costs low. All the manufacturers do that anyway. By the way, only some GXEs are limited, not "all Maximas that are not SE's" . SEs and GLEs are not limited.
