my service engine light came on even after i took my car in for the 30k service. i just disconnected my battery, but how long will it be till the computer resets?

 

it takes about a hour to a hour and a half i think

 

hmm...i read b4 that it was 4-5 hours. i dunno. i'll be leaving work in 4 hours so hopefully that's long enuff.

 

I left the neg unplugged 16 hours, reset the radio but not the SES. I heard something about having to disconnect BOTH, why is beyond me.

Went to the dealer, got the SES reset and has never come back on.

 

This is one question I've always wondered about. In my Prelude, it like any newer car, was OBDII. In the Prelude we were told to reset the ECU once a week sinec OBDII tries to counteract your mods to remain compliant to its emissions codes. I wonder if it is the same with the Maxima as well. Does anybody know?

 

The only real way to reset the thing is with a OBD-II scanner. As for the computer learning your mods, at WOT, the fuel maps are hard-coded and the OBD-II computer info is probably bypassed.

 

Hi

 

hey there

 

post wh0rez!

Hey Maximus, did u get a chance to run ur maxima at the track this weekend? just wanted to see what ur times were

 

Yeah, I ran unfortunately...lol. It was around 87 degrees and the humidity was around 80%. It was miserable and my times suffered. I ran 14.4 all day with a trap of 95-97mph. Thats 2-4mph slower that when I was stock, clearly the humidity was killing me out there. However, it was good practice for launching. I was hitting consistent 2.2s. Basically, the best launch is a fast clutch release from around 3K rpms. I tried feathering from 4300 a couple of times just to see and ended up getting 14.7 times with horrible 60fts. No more of that. You need to launch low in order to take advantage of the torque curve. Ofcourse I'm sure you already know that.

 

factory service manual for 1st and 2nd gen altimas says disconnect the battery for 24hr. The dealer guy agreed, but said 2days just to be sure.
I'm not sure about 5th gen maximas cuz dont' they use obd-3?
