I don't have an uprev tune yet, this was a failed attempt... there is something wrong with the voltage levels on my car either because my "new" ECU hasn't been inititialized or because I have a few things missing such as HVAC connections... we're going to try again in a week or two once I plug a few things back in

Suggest you have your tuner speak directly with UpRev regarding your situation... doesn't make sense to me that the rpms would be limited below stock levels as you describe

I know the questions wasnt for me, but we could tune all the way up, not just to 6400. Something is wrong with your software...

Car ran very well today at PIR. Last time I was there I ran a 1:13.3 on street tires... This time I broke through 1:10 in my second session and third session posted a 1:09.5! Pretty happy with that result.

The car weighs exactly 3,175 with me + full fuel... my dyno was 300whp and optimistically I will gain +20 with a tune, which means my weight / power ratio is 10.0. That is too far off the target for "TTS" of 8.7, so I am now forced to change plans. I can either go SC and tune it for 375 or so whp, or I can try to get the car classed 1 level down to "TTA". The later option sounds very appealing because the time I turned today is a typical winning time in TTA - or close to it.

In order to move down 1 class, I have to do the following:

- switch to no larger than 275 series tires (run 275 square)
- switch from Hoosier R6 to Nitto NT01
- swap back OEM sway bars (but I can run 18K/16K spring!)
- add 100 lbs of ballast, for comp weight of 3,250 (note: can add ballast wherever I want)
- remove canards
- remove front splitter (didn't have on today anyway)
- convince NASA that my sport model Z is equivalent to a non-sport for classing b/c I swapped out the brakes, wheels and diff and those are the only real differentiators... they may require me to run without SRM, however

Another thing to note... I was pulling sustained G's today upwards of 1.30 and as a result had fuel starvation with only 1 light down from full!

NIce! Great drop in lap time! That's on the "big" track, correct?

yessir, the "big" one

LateralG'z · 05-03-2010, 07:51 PM

Nice work, you might have to start to take this up professionally judging by your improvements.

travisjb · 05-04-2010, 12:25 AM

haha, thanks, but in my dreams... would need about 1,000 more hours of seat time for that... a year!

FuszNissan · 05-04-2010, 02:19 AM

Nice Work Travis

Bluemeanie · 05-04-2010, 09:46 AM

Good driving Travis!

travisjb · 05-10-2010, 11:02 PM

Dyno tuning results! good results, but still a mixed bag...

The top line is with the muffler completely removed... I had no idea that the Burns muffler was that restrictive... I'm a bit surprised... I may end up just running a straight pipe as a result of this

BIG THANKS TO TIM AT XACT DYNO! I'll be going back there again once UpRev increments the software to include valve and cam adjustments

travisjb · 05-10-2010, 11:06 PM

New BC Racing coilovers went in today! 18Kg/m front and 16Kg/m rear springs!!! it's going to be a brick... Having the original set boxed up with <10 hours of drive time on them! Going to make someone a great deal

Car goes to paint tomorrow (scoops, interior)... unless someone has a better idea, we're going to go with something like Nissan's matte gray metallic (AG03), but a few shades darker

Dibs! Were the original the standard BC spring rate for the Z?

Fathead · 05-11-2010, 11:10 AM

How does it sound with no muffler?
