Ultra-strange timing behavior with Cobb - any ideas ? Pics and logs inside

[cstavaru]

Hi,

6MT FBO RB + Meth here. Running Cobb. It begun occurring on a map in which I increased the timing by 1.5 degrees at higher RPMs (5500+) compared to a previous map that did not exhibit this issue (but I will have to re-load that map and check again - maybe now it happens on that too but I kind of doubt it).

It first occurred today on the dyno, and then when I did some circuit runs this evening it happened again. Basically the timing is completely erratic, in the log on row the timing is correct, the next row the timing is ZERO (or close to).

I have attached a log picture (it isn't pretty) and the CSV log. There are some timing corrections on some cylinders but I am sure they are not related to this problem. I have also attached a dyno picture to see how it affects the torque/power. The dyno is not related to the posted logs but the dyno log exhibits the same problem.

It seems to me like a torque limitation algorithm in the ECU or something. Any ideas on how to fix this ?
