    Nissan/infiniti timing maps not work

    Hi to everyone, i try to tune a 2 g37 on the dyno and the timing maps don?t do any changes at all. Always give me the same log of timing and the car can?t increase HP. Hptuners write me that the main map is trimming adjusting map, but i move every single map and vvel maps, vvt and get nothing, fuel is perfect the car made 311hp on the dyno, we use a other program, the one every people use before and the car made 340hp. I think is one table missing or the computer have some protection tables that I can?t see. Is not talking bad about the program because the car run good but is a constructive criticism. Plus a 2step or race rom can be perfect to be more competitive software

    We are having the same issues with timing control on a 2014 Q60, no matter what tables we change nothing happens, even zeroed out the table and set some to 10 degrees on the whole table and the results are the same. I think that some tables are missing also

    Keep in mind the Nissan timing control on a VVEL engine is a bit weird. You can basically zero out the whole spark table and within a few minutes it will have the timing advamced back. They use the knock sensors for spark advance learning.

    On my 2011 M56S I simply smoothed out the timing map and let the PCM relearn. Pull a few degrees out of the main spark map and smooth the table at high load.

    Most of my power gains on the M56 were from correcting the over rich air/fuel ratio, remapping the throttle, and tweaking the VVEL tables to bring the cams in more aggressively for the air intakes & 2.5" dual exhaust upgrade I did.

    having the same issue no gains from adjustment of timing maps. ECU does not seem to respond to changes made to the maps defined for timing control. I suspect that the timing control algorithm of the ecu does not allow for adjustment of the final timing plane angle output. Or the disassembler at hp tuners has incorrectly defined the tables pertaining to timing control.

    Read my prior post. It has to do with the knock control and learning on these engines. The ECU already adds timing as necessary and runs at the highest possible timing advance via knock learning. You can set the tables to ZERO and after 2-3 WOT pulls your timing and power will be back to normal.

    I am having the same issue on a 14 Q60. Customer wants a "pop" tune and ive adjusted every table trying to get the timing to move and nothing seems to work.
