So I have a 2001 Nissan Maxima I want to tune it I have obx headers and cold air intake and Megan racing muffler but everyone tell me I can’t because the computers is to old school I was wondering if anyone has tuned 3.0 maxima and what program they used so I can tune my car

So why are you posting this in the 4th Gen forum? 2001 ain't 4th Gen.

 

True. Figured it's harmless to post here since it's the same engine with a slightly different UIM.

 

I would imagine by 2001 the ECU was programmed differently as well, so "Tuning" from our perspective might be a disaster.

5th Gen guys who've done it will be his best resource.
