injector duty cycle

Hi guys
Anyone had any luck getting injector duty cycle working on the scanner?
Or let me guess...... sct?

I've never had it working. I believe you can't log injector duty cycle with SCT either, you have to use another logged pid and run a calculation. I just can't remember what it is in SCT. TOADS or HIDDEOUS will clarify.

Never any luck from the scanner.

From my SCT logs you need to log FUEL_PW_CLKTIC and RPM.

Duty cycle is FUEL_PW_CLKTIC*RPM/1.2 (1.2 is from RPM/(60*2) to get available time then * 100 to get %)

is it accurate or is it like some GM cars that show 110% duty cycle?

My logs indicate the SCT data is accurate.

Not sure how accurate the GM data is but sounds like it is not reporting the data at the same time or with the same granularity or both. What was used to log it?

would need to check with my mate, not sure whether it was HP or EFI but there was a pid for injector duty cycle and it would read more than 100%

Eric or Keith
Would it be possible to add the injector pulse width into the pid select list?
