Good luck bud! A group of locals are going to the dyno and 1/8 within the next 2 weeks. I have yet to tune mine at all. I'm not even running the base Z map, just stock setup from the ecu. I will have a baseline soon, and then I will tune, and run it again. Hope you get some good numbers from the tune, cause that hopefully will mean I will as well.

 

yoooooooooooooooooooooooooooooooooooooooo

i got a few pics...





and on that time note, it was a ***** to do, took ~6-8 hours of total work, but i did it oer a week...



the hardest part is breakin ya neck installing it in the car..


utec is def the best route for 5.5+ max ill get one!!! after i find some $$$$

 

y does the second pic look like ur not using all of the ecu pinouts? does the utec only have to see certain pins?

 

That's correct. You don't have to use every single pinout. Just the ones for what you need to control. Actually, we used the EU also as a guide as to what needs to be used.

 

could u let me know how many and which pins need to be used? and the rest u just taped?

 

I'll ask Darren (SurraTT) to chime in since he's the one that did it for me.

 

going from memory here


injector 1 2 3 4 5 6
ignition signal 1 2 3 4 5 6

ecm ground
power for ecm

maf sensor
knock sensor
tps sensor
crank sensor

mabey other, but i think thats the basics

 

and i grouped the wires together

like injectors were red,
ign coils were green

others were diff color

 

any quick links to the 350z fsm you used?

This is awesome I will be looking in the near future to do this with my sentra

Great thread!
This is the best Tech I can find for UTECH for a 5.5 generation Maximas.
Time to revive this thread!
I bought a 350z UTECH that I plan to use this thread's tech to convert it to an '03 6spd Maxima connectors.

Any tips further on the Pinouts or should I consider the above as complete.

Does anyone have a UTECH All motor MAP for an '02/'03 Maxima to share? I see there are some challenges making the base 350z map to work out of the box.

Thanks!

 

I make a utec plug and play harness for 02 03 maxima.

visit my website.

 

It's UTEC...no H

Check the 4" intake thread. http://forums.maxima.org/all-motor/6...2-08-vq35.html

I've got maps

 

Surra, pm me a price on the harness 03 Max 6spd.

MrEous, I added the "h" for high power!
Thanks for the link to your MAPs, I see I would have to swap injectors to get in the ball park.

I read there were issues running Utec on 03 Maxima's when cold, was this ever sorted out?
