I didn't feel any misfire, no, neither did i feel it the other times it happened. Yes, i see the spike on my rev counter clearly, it goes crazy, it drops very low and then up again.Jadzwin wrote:The fix was only for cranking. So you have seen the spike on your rev limiter ? Any misfire during this ?nickbmw wrote:Rev counter went mad again today, so 2.041 didn't fix the issue, at least not besides cranking
And another possible issue. The trigger delay value seems like it's not working properly. I tried to align the timing on two S2ks (F20C) using the stock ecu as the reference, and the delay value doesn't seem to do what it is supposed to do even if i set it at 255us.
I follow this procedure :
install stock ecu.
Monitor cyl1 ignition advance and RPM from the OBD. At 6000rpm it gives 45degrees of advance.
I marked the pulley at 45 degrees aprox. as it only has marks at 3,5 and 7 degrees.
Rev to 6000 and adjust the timing light offset so the 45 degree mark aligns. Timing light needed 3 degrees offset in my case today.
I then install the EMU Black, set advance at 45 degrees at 6000rpm in the map, and i start adjusting the trigger delay value until the 45 degree mark is aligned with the timing light set as before from the stock ecu testing, to make it match with the factory ecu which i consider correct. Even if i set the trigger delay at 255us, it's falling several degrees behind at 6000rpm. It looks like the trigger delay number does nothing above a certain point.
Can you advise?
