Atleast that's how it was explained to me.

...any thoughts on the best way to dyno this thing?
I have a place lined up to do 2 pulls before & 2 after.
I'm just wondering if consecutive pulls is a good idea or not,
considering heat load for the last two & whether the ECU fully adapts, even with a quicky reset.
..or do two separate days after the ECU has learned the new settings.
- problem there is getting similar atmospheric conditions. (plus added cost)

Doing it on separate days will also work, so long as the results are SAE corrected.
Do you know someone with a Grassroots Motorsports magazine? This month's has a pretty in-depth coverage of how to properly do a dyno-run and get the most out of it. I don't have a scanner but if you want i can start taking photos of each page for you.

No. I've discussed this in detail with my local Infiniti shop and they all agree that your ECU will automatically retard the timing back to zero deg. The bullydog "over rides", if that's the term you want to use, and keeps the timing advanced.
Atleast that's how it was explained to me.

It offers more than a +2 degree timing advance.
#697
Yeah the BD offers quite a bit if you ask me, this is something I am still dying to pick up as a result. Would most likely have mine now if I diddn't pick up my intakes a week ago. BD sounds like one of the best mods you can do for your G.

Am I wrong or is this pretty much a "one size fits all" tune? Specifically, it doesn't take into account what other mods are done to the car as an UpRev tune might. So those with a stock setup could run the premium tune at +2 timing and be okay, but what happens to someone who has intake, plenum spacer and full exhaust mods. Wouldn't the AFRs at WOT be different between the two cars?

My understanding is that this "tune" does not interfere with the ECU's ability to adapt to changes.
This is a very good question and one that I alone don't have the answer to. I do know that I've seen impressive gains with this thing and find it to be worth the price of admission.
I think that UpRev would allow for slightly better gains, but that requires more $ up front and the cost of a custom tune as well.
For me, and others who don't want to go through the tuning process, this thing seems to fit the need nicely.

I'm a new member, and this is a great (but long!) thread. I've only had my 07 g35x for 6 weeks, but I wanted to share a little info about my other car, a 03 supercharged eclipse gts.
2 1/2 years ago, before going FI, I had the "normal" mods--I/H/E, as well as a few other less common ones like HFC, oversized TB, P&P's upper/lower intake mani with spacers--all tuned with the SAFC2. Unfortunately, my car (remember, only 210 crank hp stock) STILL felt like a dog.
Fortunately, ECU flash came out for our platform. I jumped all over it. For those not familiar with it, ECU flash allows the user to change things like AFR's, timing, and accel enrich, among others. After 6 WOT pulls on the highway with datalogging, each time sending emailing the logs to a tuner, who changed my rom so I could reflash it, I took it to a dyno and saw a 12 whp/12 wtq gain between the stock and reflashed runs (sorry I don't have the dyno sheets anymore). I should also mention that there was no knock, even with increasing timing by up to 4 degrees and leaning the highest RPM/load AFR's from 10.5 stock to 12.5 stock. The car felt faster--apparently not fast enough since I went FI anyway
So, maybe apples to oranges, but if I was seeing those kind of gains on my piddly 3.0 Mitsu motor, if Bully Dog does the same kind of things the ECU flash does on Mitsu's and Subi's, we should see even more gains on our kick-*** 3.5. This might also help put those members' minds at ease who are wary of a 2 degree timing increase, or of running too lean. I can't see how BD would put out a tune that could kill a N/A motor.
Once I take care of some routine maintenance issues, I definitely plan on going with the BD.

I hate to beat a dead horse, but seriously...where are some legit dyno runs to test this thing?
