It sounds like you have too much ignition advance and that can destroy pistons, con rods and wrist pins.... to the point of catastrophic fail.

I would first check that it flashed correctly. If you were accidently running the stock 370z tune, it would be doing exactly what youre talking about.

Yes i reflashed it back to the R4 tune where it was running better without the ping. I'm pretty positive it was the correct tune chosen because the only thing about this tune was the ping, other then that the car ran amazing. Much better then previous tune

The ping would come in around the 800-1700 rpm range.

From the rpm ranges you stated, it sounds like tip-in knock. I've seen it on a few 370's even with stock tune. Does it knock under load too?

Good point. I was thinking high rpm/full load. Cars back in the 70's would have tip-in pinging and still last more than 100,000 miles.

Yes i'm aware of tip-in pinging, some of my previous cars had this and still runs perfect till this day. But the pinging i'm getting here is head turning!! People would look at me like 'dude your car is messed!!' kind of look.

It only seems to knock under load. Starting in first gear the knock would be very drastic. Switching to 2nd gear at around 3500 rpm there would be a light knock but only for very short period of time. While in motion with the higher gears it would not knock when i'm gradually giving it throttle. But if i throttle it a bit aggressively it would knock.

It sounds like theres a bunch of ball bearings in the engine bay just jumping around around as i accelerate.
