I'm having an issue finding how to adjust mu duty cycle in Tunerstudio. My 95 is running pretty nice, but I need to get into the details now. I have been reading everything I can about setting idle and initial tuning, and most everything starts with finding min and max duty cycles. There are lots of good write-ups, but I can't seem to find how to do it in the newer versio of tunerstudio. Is it a better idea to start with megatune? Or am I just missing something all together?

duty cycle is just pulse width divided by RPM... cant remember the exact formulas off the top of my head. But something like 16ms of pulse width at 7000RPM = 90% duty cycle.

so duty cycle is time the injector is open.

you can only adjust your duty cycle by altering how much fuel you are injecting.

And what does MS fuel off of? Your VE fuel Table of course...

Thanks, Brain. So adjusting the ve table will change the duty cycles. I seems most of the old writeups are designed around megatune or older versions of TS.

the theory is all the same. the MS fuels off that table, it's your main fuel table.
