ECU tuning option
#31
where is the crank angle sensor located? can someone make a unit like this:
This is the STeeda timiing adjuster fro 4.6L Mustangs. Basically, you pull the crank angle sensor out of the block and mount it to this unit. This unit is also attached to the crank shaft. It allows you to adjust timing +/- 10*. Very cool and very effective.

I guarantee you that they are flat out lying to you, 6969g35. You cannot adjust AFR at all, cannot even adjust idle on the lev2 cars, can adjust timing +/- 2 degrees, and that's for testing purposes only...it doesn't stay there, and goes back to normal.

But seriously... they did change the mid-pipe in the exhaust, as well as the rear hangers on the muffler.

Question: Did anyone ever figure out whether or not the timing advance is permanent?
On my 2004.5 G Coupe, I was having a problem after my header install with the rpms dropping down to ~500 or just slightly lower whenever I put the car in neutral (like when coming up to a stop light). I had the dealership try to raise the rpm on my post 10/2003 ECU and they couldn't! (This proves Gurgen was correct above) They then advanced the timing by 2 degrees and the rpms went up by about 100-150 at idle. This took care of my problem, or so I thought.
Well, as of late, the rpm drop appears to be rearing its ugly head again and I'm wondering if I hooked up the consult-II if I would get a reading of 2 degrees advanced timing or if it would have reset back to stock. Anyone care to take a guess or share an educated, factual tid-bit with us? TIA...
BTW, LokeyInfiniti installed a SAFC-II on his loaner G Coupe. He had it dyno tuned for ~6rwhp (if memory serves correctly) and he was going to have it re-dynoed a month or two after his initial dyno. I think it's time for that second dyno...

I asked what was the dealer price, i.e. perhaps you know a shop that could order you one, and they said the price varies. My guess is that it's probably $4K. Hope this helps. If anyone knows a shop willing to help out with the purchase, please let me know.

Just to throw my opinion out there (even though it's not worth a damn.....however, Doug at Crawford Z confirmed this with me):
Reprogramming your ECU is pretty much worthless on the G35/350z if you are already running high octance fuel.
If you are like me down here in Texas and running 93 octance, forget about it and don't waste your money. It's $500-$700 down the American Standard urinal.
It might make sense for some of our brothers out in Cali with 91 octane being the highest.

whoa......anything you have that can back you in this?.......i'm really curious now since i was about to reflash w/t/square.....headers, crank pulley, ztube w/kn filter, removed pre-muffler and 50hp nitrous..............91 octane is the highest here in so-cal....so maybe that statement doesn't apply to us?
