07 HR reflash completed!!
I call, but Tadashi was busy with a customer, so I shot him and email with a bunch of questions. As soon as I hear back from him you guys will know.
I know you guys want dyno numbers, so here we go. Mind you that I don't have all the dyno sheets with me, so there were some changes in mods durring this. I know that changes things a bit, but at least you'll see the total increase that is available.
When the car first went in it was dynoing at 230hp and 206trq. This was with Fujita intakes and Nismo exhaust. The original prototype reflash ended up producing 247.8hp and 217.1trq.
The second time it was taken in, the initial baseline dyno was relatively the same (within a hp or two). For the final dyno the car had crawford HFCs, Nismo exhaust, and stock intakes. The final numbers were 261.6hp and 233.2trq.
Some interesting things were discovered. The stock cats on the 07/08 Zs flow much better then in previous years. The addition of HFCs help, but not by the same amount that it has for the older cars. Also, the stock intakes flow really well from the get go. Part of this is probably due to each intake only requiring half the air as in previous years. I don't have all the numbers, but with the Fujita intakes, the peak hp was slightly higher probably within a few hp, but the over powerband looks nicer with the stock airboxes in. My guess is that there will be very few gains from intakes on our motors. The best we could hope to do is cut down on some of the turbulence produced by the flex pipe used and hope that it just adds a bit of power without disrupting the power band.
I don't have access to a scanner at the moment, so I can't show the actual graphs. Oh, and the final max A/F on the car was 13.9. Overall though the A/F is around 12.
Hope this can hold you guys over for a bit until I have more for you. Oh and the dyno that is used is a Superflow (I believe). Its known to read low numbers, so look at the difference between the before and after numbers and not the numbers themselves. The corrected numbers on this for a dynojet would look much nicer.

so essentially you can be bone stock and benefit greatly from this tune? the only mod i'm interested in doing is a nismo exhaust. do i have to get the exhaust before i get the tune or can i do it the other way and still benefit? thx.

Unfortunately I don't have the other dyno sheets that would give a moor accurate number of what just a reflash will do. They exist, but I just don't have them. Either way, just looking at the dyno numbers from the first prototype the gains are great and figure there was some improvement over the original prototype and the final program.
Thanks for the update. Either way its look like at least a 15hp/tq gain. Can't wait for them to release this.
