Interested in 5.5 gen ECU reflash? I have good news coming soon...

For whatever reason the forum has not been giving me notifications, nor my app....hmm. First thing I will say is watch out for Jason, his rep isn't so good(google.) Secondly, I will have news by the end of the week(probably sunday) and will have all the details posted here. At this point my thoughts are as follows: DE flash for bolt ons(10-15 whp depending on Octane available locally and mods) Partial flash with Intake cam timing changed and rev limiter raised(for those who have a tuning solution already.) Rev limiter flash(for those who have a tuning solution already.) These will all come at different price points. The DE bolt on tune is essentially finished, and has been dyno'd(made 253WHP on a mustang dyno.) Mods: ebay short ram, obx headers, ebay 2.5 cat back w/ test pipe, BOP, partial nwp spacer kit.

In addition, within the next month or so I will be doing a DE with a 4" intake and GTR injectors(along with the other bolt ons) and also a Altima "HR" swap Maxima that will be running GTR injectors and a 4" intake, so those will both be options down the road.

OMG YES!! Been waiting to see this. Trying to figure out if i should buy the 4inch intake and injectors first then get this or get this and get reflashed later when l have funds available for the 4inch. Problem is l can only do one right now not both. Uhg decisions
Is the 4inch intake and injectors worth it?

The 02-03 doesn't close the throttle like the later vq. It uses a different ecu. The rev limiter on this ecu flashed de is 7150, but have ran as high as 7400 on a " fwd hr" for some testing. It doesn't make more power past the stock limiter, but shifting higher puts you in a better part of the power band after shifting.

2002-2003 Maxima 6 speed bolt on tune is as follows:
Rev Limit only flash: $175
Rev Limit and Cam Timing: $225
Full Flash with Cam Timing, Rev Limit, and AFR: $275
The full flash has been tested with a 2002 Maxima with headers(obx), short ram, test pipe, and 2.5" exhaust, and shows approx 10-15 WHP/TQ gains around peak along with very large gains in the midrange(20wTQ), in addition the rev limiter is raised to 7,150RPM.
Dyno results show 253WHP on a mustang dyno, and back to back runs on a stock ecu(with +2 base timing) show 244WHP. Dyno sheets are in the post below.
You would send your ecu into me(and pay shipping) and I will flash it and send it back via priority mail. Turn around will be 2-3 days + shipping time. This can then be plugged back in your car and run(although you will have to clear any codes from the flash.)
The tune is developed to run on 91 octane or higher! Base timing will need to be adjusted to suit the particular octane in your area. Testing was done with a base timing of +2 on 93 octane to enable those with lower octane to remove some base timing if needed.
The first 5 who purchase the "full flash" will be able to get the discounted price of $200.
Please PM me and I will provide my paypal and shipping address. Feel free to post about any questions.
Within the next month or so a tune for HR engines with bolt ons, 4" intake, and GTR injectors will be added to this(cost will be the same for the full flash) as well as adding a tune for the bolt on DE with 4" intake and GTR injectors.

Thank you for the 
Hate to hog this thread but i started a thread here with a 2001 i bought in the process of assembling parts to restore it.

On another note the first ecu is on its way here and should be flashed within the next few days, and off to its new home.
Would a double re-flash be cool? Meaning one now for the full flash and another once you've done the 4"+440's tune? Or would that cost double?
I have a 4" cgr intake, 440's, & bigger fuel pump in the works, just not on the car yet. '03 de not hr. I have the other bolt-ons you mentioned though so I'd pay for a full flash now if I could send it back in again later.

I want to see what kind of power the 4 inch intake and gtr injectors make. Am 99% positive l will be doing this. Wont be u til may or april. So l will be getting tuned again.
Can't wait to see the results.
So exited that a car this old is still getting love

I'm in the same boat. I'm very interested. Another question is does the flash include dbw adjustent similar to the Technosquare flash. If that's possible, I would trade my Utec for this plus I just want simplicity!

The 02-03 only uses fuel cut for revlimiting.
USPS got that there QUICK! Let me know how you like it, any feedback would be appreciated as I want to work with customers as close as possible to ensure that everyone is satisfied.
