ECM Reflash Results by TechnoSquare
My dyno results!!!!
Date: 4/10/2008
Car Specs: 2007 Nismo 350z with the Nismo Dual CAI.
Dyno: SuperFlow WinDyn Dyno V2.7, calibrated on 4/2/2008
*NOTE the numbers below are wheel numbers, not top-side numbers
Governor settings=185 (changed from 155)
Tach settings=7500 (was not changed)
Before HP=280 RPM=6900 TORQUE=242 RPM=2700
After HP=292 (+12) RPM=6900 TORQUE=256 (+14) RPM=2500
The Throttle changes was the change I noticed most on my drive home last night. I feel like it really makes a difference when it is punched esp. at higher speeds.
Also, for some reason that I cannot explain... it is easier to shift smoothly...

Nice numbers
Nice numbers
I filed a formal complaint with Nissan about the alleged gains and ... we will see where this goes. I am selling my Nismo air intakes!
The Nismo actually reduced my HP by 7-10 throughout the range!!!

Please DO NOT waste your money, as I have, with current aftermarkets systems as they do NOTHING but give you a look and sound.

Damn man u dyno'd at 280 with the just the CAI?? Somehow i dyno'd in at 249.6whp with intakes and exhaust and 210.4Trq only.
After the reflash and dyno tune we got her up to 287.9whp @ 7000
and 243Trq @5200.
Im really dissapointed. How could the Z dyno in at 250whp?
I did notice a huge difference in power, push and throttle response its amazing and considering the reflash got me 39whp and 32.6Trq increase!!
My buddy is hooking me up and we are going to test the Z out on his DynoPak starting with the Nismo CAI on and then swap to the stock intakes and see what kind of numbers we get. He really finds it hard to believe and almost disagrees that im only getting those numbers he thinks it should be a little better.
Do have to keep in mind that it was hot yesterday!! But lets see how it goes..

Thanks,
Thanks,
They Dyno'd it. Did the air/fuel corrections. Dyno'd it. Reflashed and tuned for optimum results. Dyno'd.
It took 1.5 hours only. $700. Very worth it. Even if my Z dyno'd low before the reflash, after the reflash and tune +39whp and +32 trq.
It may not be that much for everyone considering my car dyno'd quite low but shows u how affective it is. Just on throttle response its more sensative.
I gained a 15% in power to the wheels.
