Spark CUT
« on: May 04, 2018, 11:58:17 am »
HI,

I am experiencing issue similar like misfire but I found that it is "on purpose" ECU by some reason is doing 100% Spark  Cut for unknown reason, in random RPM.
I am able to simulate conditions like you have lifted car spinning engine on 5 gear and doing load by brake. It would be considered as low-medium load.

do you think, would it be easier to understand what's causing it if you uploaded some log? :D

Any  ideas guys ?

For example I didn't found " spark cut" except REV limiter and Launch control and didn't seen that also within that "calculation" view...
Are reasons/functions for it documented somewhere ?

Cause has been found.

Anytrim    Redline RPM Trim for Lambda target 60% TPS  and Lambda target 90% TPS was used. In meaning of engine protection. However it was doing these cuts arround 15% of the TPS so it is not configured as I think.

read help file, 60 means not over 60% but bit different :) I would like it to be working different too :)
