Using both ignition and fuel cut but having a down pipe crack during kill period. The quick shifter box I had on the car previous could only cut ignition so thinking I had a large E85 charge going downstream, fuel cut would be better hence taking advantage of ecu doing the kills.
Came across this and wondering is the ramp in ignition is contributory. On tracks that have strict sound requirements this may be less than desirable plus potential bad things happening to exhaust system etc.

There is a quick update on shifter code now. Based on user feedback the RPM based shift kill time is changed to gear based shift kill time. Other thing worth mentioning is that after a kill is initiated both the fuel and ignition is cut. After that igntion gets semi active halfway through the kill cycle and finally fully initialized at the end of the kill cycle. This way the engine will have smoother operations during kill periods. This was not unintentional initially - so if anyone wonders how it works. (The ignition only shift kill is not recommended.)
