Can anyone tell me how far the stock 6NZs timing advances?
Would it advance comparably to a B model?
Thanks

The B model has a Mechanical Advance whereas the 6NZ is an Electronic Engine.

Can it be manipulated with cat et?
-
It is constantly being manipulated at many varying conditions proportional to RPM, Boost, Load, Throttle pos etc etc.
Remembering the Cam timing is Fixed.. It the ECm that dictates the Injection timing.

You can change about anything you want but without the correct checksum calculator it's useless. This why I asked about doing it with et

For the pm you sent me on what I use, well I'm a professional tuner so, dynojet (dyno), dimsport, hondata, bdm100, k-tag, kessv2, efilive, etc there is lots out there and I only use genuine sw. I strictly do cars and bikes. Diesel trucks are new to me :/ If my dyno did big trucks I wouldn't be on here, as I would just dyno test my changes till i got what I was looking for. Can you share with me an original file and a dyno proven modified file? also the increase? THANKS
