Besides the valet and disable options, any other map changes?

I have had my car tuned with uprev and have the tuner version.

In addition to A/F ratios, what else did they do to the car (e.g. increase redline RPM, take out speed limiter, cam timing, etc)? What does the "tuner version" do for the end-user?

They increased my redline to 7700. Unfortunately the way the ECU is designed you CANNOT ADVANCE timing, you can retard(lol) it only. Basically they just increase the redline and tune the A/F so you have a steady, safe, and consistent delivery of fuel throughout the power band.

There's only one "tuning" option available really, not a lot you can do with the ECU.

Also, I don't know of any other options on the tune other than disable and valet, I believe that's the only 2 others you can get. Of course I MAY be wrong!

The dynamic timing that Nissan uses on the 370z is extremely sensitive and makes changes depending on many variables (oil/coolant/air temps etc.) rendering timing changes in the positive to be unresponsive...the ECU determines the safest and most advantageous timing point with great accuracy!.....

as for other map choices...there are 5 slots available for maps....i usually only set 3 of them up in the power/valet/disable configuration.....

Well there you go, lol.

ask and you shall recieve...


jack, can u eliminate rear o2 sensor input completly? or does it just shut off the ability to trip the check engine light, becaused by the catalyst efficiency is below the threshold?

Hey J!...My understanding is that the ECU will omit the catalyst efficiency check when disabling the code....the sensor will still function...just the code has been removed from the functionality check list.

The inability to crack the VVEL is a real downer. I know thus far it's not really a big deal since the only real engine mod many of the forum members have done is intakes. However, when things like aftermarket intake manifolds, throttle bodies, and cams hit the market VVEL will need to be cracked unless the ECU is a supercomputer and gives you the best advanced timing automatically.

Sooo...10 hp and 8 tq peak for $500...dunno...

So then dont. Its your car do it your way as others do it their way.

I won't. Thanks.

$500 for an A/F tune and slightly increasing the redline to me is a bit much unless they promise to update your tune or give you a large discount in regards to tuning the timing if and when it is cracked.

It is not about HP/TQ gains when getting a tune, it is about the safety of the engine and staying within the range of what is "good." Power from a tune is the side effect or the bonus you get, so for 500 dollars it is a good deal.

Iwas told also u get full throttle response all the way, not like stock setting where it is set partial throttle
