What Have You Done To Your Stagea Lately?

[Commsman]

Got the new 3.538 diffs in.....got some good umph now!!!!

My fears of the speedo being out are cured.....speedo and gps are exactly the same differences as they were before.

Care to explain how a change in diff ratio makes no diff (oh look, a pun) to the speedo reading? Am I missing something obvious?

Installed my new ECU this weekend.. NISMO Sportstune

Very first drive it is obvious the difference with the car being a lot more toey of the line. Best part to be experienced is in the mid range now coming on much stronger and faster.

Next step to put it on the Dyno and see what the AFR's are like and what the actual power out put is.

Is this enough power..

because (as i mentioned ages ago) the speed is taken from the ABS sensors on the OUTPUT of the rear diff. therefore no matter what ratio the diff is, assuming you dont change your rolling diameter, the speed will always be correct as the speed is measured after all the gearing.

[Jetwreck]

where'd ya get that ratio, 34 gtr? I was thinking the same thing today.....

btw hills have a 4wd dyno. what computer?

Ratios are from then nm35 vq25dd or the pnm35....

....Hmmmm waiting for mark to give me a buzz back on the dyno.....to much longer and I'll be going to Victoria for a touch up!

The Nismo ECU's.. how do they go with economy? Better/worse?

[scotty nm35]

It uses the stock o2 sensor so it will be about the same on cruise.

[jasevr4]

So one would be much better off with something like an emanage, tune and wire cut?

Well the nismo is not tunable...

...but a nismo + emanage would be pretty sweet...

[jasevr4]

Forgive my ignorance but what is the point of the Nismo if you have the emanage?

[ironpaw]

Emanage is a piggy back...so it needs an existing ECU to control.

The nismo ECU has certain "awesomeness" in it that makes the car a bit better to drive....and speed cut too I think

Craig's car has the Nismo + emange combo...

better.......you have an economy setting, it uses the snow button!

Worse......the drive is a lot more inviting so you tend to get up it a little more.

[bigkevracer]

I think the main thing is no speed cut and no throttle restriction isn't it?

Has anyone with the Nismo snipped the brake wire?

Don't need to worry about that now though...

[scotty nm35]

Are you sure?

[Sunkist]

Are you sure?

lol +1..

im pretty sure craig noticed a difference after the snip still

[zei20l]

yup, initial throttle response from standing is better

[scotty nm35]

I think he means with the fcon, the stock ecu still controls the throttle though. There are 4 wires extra in the loom plug I can't account for which may make some changes, not sure.

[Sunkist]

yeh and the fact you had throttle cable. i wouldnt be sure that the Fcon would completely eliminate the throttle restriction.

Doesn't explain how the throttle changed on my car.

Both much more responsive and also more soggy depending on map selected...

Without the infometer you are only guessing though. It could easily be tune related.
