NISformance Mail in Re-Flash

This service includes our base tune. It is intended to offer gains in performance while retaining a level of safety. This service is intended to be used on naturally aspirated vehicles with light to medium modifications. This service is not available for forced induction setups. You must ship us your ECU, We do not provide an ECU. This is a re-flash service.

We are excited to introduce our new advanced features for the 02'-03' Maxima. These features introduce a major advancement for the 02'-03' Maxima platform. This is something that we have been working on, and developing for some time now. These advanced features allow us to offer multiple maps, launch control, flat foot shifting and shift light. Prior to this, only UpRev supported cars had this ability.

We will be offering these features as an optional upgrade with our mail in re-flash service as well as a stand alone option to those who are already tuned by a different tuner. If tuned by a different tuner, we can add these features without affecting your current tune. Please send us a message or email for more info.

Note: Adding the optional ARC license(04'+) allows for improved ignition timing strategy. This results in increased power gains but also a much improved "pops and crackles" map.

5 of 5 Worth it January 23, 2023
Reviewer: Steve Garrard from Vancouver, WA United States  
If you have a 2nd gen swap absolutely get retuned. I drove for 2 years untuned. I wish I hadn't waited so long.

Reviewer: Andrew Anderson from Washougal, WA United States  
Tune exceeded my expectations. Only wish they had a couple more categories on their tune form. Like rev limiter, speed limiter, eco tune.

2 of 5 issues but finally fixed it November 6, 2022
Reviewer: Stephen from Houston  
sent my ecu out to get this service filled form out with exact parts. installed it back into the car and would not accel correctly and set system lean dtc, contacted nisformance said do to a idle re learn and pedal re learn. performed it then the car died after 30 sec of idle. and still won't accel   contacted again said it's the engine issue.  installed new oe maf no change, installed a used ecu from ebay car runs great with no issues other than p0420 and p0430 and no cruise.  contacted them again never got any email back. bought the nisformance intake 3 inch and put a newer style maf sensor in it and reinstalled the tuned ecu, vehicle now runs with no other issues or codes. the tune is great but dealing with trying to get them to admit the tune was a issue and ended up having to buy more parts to not waste the ecu not sure if i would recommend it. since i ended up spending the same amount if i would have taken it to admintuning for dyno a tune=========================NISformance reply - From what you said it proves this it wasn't a tune issue, sounds like it was a MAF issue.   If it was truly a "tune" issue it would not fix itself and be good now.  You literally said "the tune is great" in this review.....

5 of 5 2000-2015 Maxima Mail in Re-Flash October 6, 2022
Reviewer: Samuel Lopes from Kissimmee FL  
I had the ECU in my 02 6 speed flashed and it made a huge difference. I run 245/40-18 tires and they had plenty of grip with just bolts on. once I got my ECU back the tires would cut loose in 1st gear at around 5,000 RPM and pull all the way to the new 7,2000 RPM redline. may I also add that the engine had around 305,000 miles when I started throwing bolt ons at it last year, mainly intake and exhaust mods....
