Thanks!
Thanks!
this is just for the 5sp/ manualmatic trans... (no VDC no traction contol)
we are doing the traction control, 6sp trans as of right now..
4sp will be on the list soon..

I have a 5AT w/TCS and i dont think i have VDC though... how can you tell? prob not... i guess i will need a stand by ECU if i am to do this>?? .....just read the whole post again, and i am stoked about this.. i can see why we have the dual stage instead of single like the G-35 and the Z... Our cars where built for fuel savings, instead like on the sportier other VQ's... Sounds like a really nice mod.... cant wait till you get eh stats Tek!!! Sweet..

If yours is compatible w/ mine, you'll be out of a car for 2-3 BUSINESS days, provided you use overnight service both ways.
Where's Tek w/ the dyno?

im just curious, i really dont know to much about this into detail like some of you do so dont laugh lol, but if the Z ecu is working for our cars...why not just keep that in, whats the benifit of actually having ours reprogrammed?

Maybe Ill get better gas mileage? I undertsand that the car runs very rich at high rpm and the throttle closes some. I think the reprogramming keeps throttle open and leans out the mixture at high rpms.

Is the 6 speed ecu gonna be done soon? Also someone mentioned about 6 speed with and w/o traction control and I was wondering if it even mattered if you have it? I assume they can program it if you have it or not.

Glude, Tadashi said mine would be back in 2 weeks and that was on Wednesday of last week. So its about 10 days away, if his estimate was accurate. As always, ill keep u posted.

They run lean because the Z33 ECU controls the larger 335cc injectors. A33B and A34 injectors are 315cc.
You would want to get your ECU reflashed vs. just running the Z33 ECU for that reason, and so you get an extended rev limiter and the fixes for the throttle control. OE programs for DBW systems don't give you 100% control of the TB. They're most often limited at low vehicle speeds and near the redline.

Thanks. This is really interesting - I can't wait to see the new dyno.

sr20 did you invent the maxima?

well, Tadashi did a great job with my A/F, now is perfectly straight or close to it, but still runing lean cause he didn't run me at 12.8 wich is best vs the 13.8 I have now..
if we can run 12.8 all day, we can get maximum hp out of the ecu... I don't like the graph since I lost power cause of it, but I'll show you the update..

I usually tune my car, and other Maximas, to about 13.5 - 14.0.

damn, cause I lost some hp on those runs vs last time, if this is maximum is only a 9hp and 9tq gain, wich ain't worth the money for members going to buy it straight out...
once i put headers and a cattback, it will get leaner and it will be worse than that... I don't wanna loose anymore power with bolts ons later on..

You also need to do something about that torque converter locking up on the dyno. That torque spike is skewing your results.

Can you send me all your run files?
vqtech@gmail.com
From what I can tell you've only lost 2 peak hp, and that doesn't really say anything vs. your previous run.

Most of these runs are pretty much the same. Run #9 is probably your best overall. But the A/F does need to be as flat as possible.
For most people I suggest getting essentually a Z33 L-Spec map but with the A33B/A34 fuel maps to run our smaller injectors.
Then get a VAFC-II, or similar, to do your own specific A/F corrections.

If I get a VAFC-II, I'm sure my dyno tuner can mess with it good... we'll see..
