must run at constant the 43 psi fuel pressure.
The voltages are from a Z32 mass air flow sensor posted by Precision Flow Labs. (see reference thread)
You must convert to ms for some standalones. here a link to help you with that: Stealth 316 - Injector Duty Cycle Calculation (http://www.stealth316.com/2-calc-idc.htm)
They are also for 14:1 air fuel ratio so plz keep that in mind and add 1% to 20% depending on AFR, boost, knock and IAT, coolant temp and exhaust temp.
They also don't take into consideration that some of the fuel sticks to the injector's vicinity.
If you believe the numbers are wrong plz post what you have calculated.
It would be very nice to have people post how much the numbers match their tunes.
