Fuel pump PWM control
It would be nice to have PWM max and min DC and frequency adjustment. It would be also great to have two outputs, one for PWM signal and one for pump power on/of (for pump on after powerup) because pump controller that I have needs 10-95% DC control range (@100Hz). If it receives 100% DC signal it will limit fuel pump capacity to 45% and if does not have signal it will allow 100% fuel pump capacity (see the link for the pwm control sheet). Basically this PWM fuel pump control that we have right now is completely unusable in this case.

missing pulse detection
(FPhil)Can we have an immediate missing pulse detection particularly for coil type setup, in order to prevent running out of sync?
Per example, a trigger pulse could be declared missing if it does not appear in a time window which could be predicted base on the last coming pulse and engine speed. Options could opened for what to do then : "ignore","stop engine till resync", "use prediction", etc..
Boost ceiling
gstuning proposed (ChatViaIrc)
Can we introduce a boost ceiling curve ?
- for example I want to have 250kpa boost at 3000rpm and 200kpa at 7000rpm
- but with a 0-5v anytrime input I want to be able to increase the boost at 7k to 200+50=250kpa
- but not increase boost at 3000rpm (to 250+50=300 kPa), stay at 250kPa ceiling.
Correct:
- boosttarget+=50kPa would apply to all RPM currently. There is currently no configurable "boost upper limit".
- maybe fuelcut_max_kpa -20 kPa could be used to maximize boosttarget when anytrim boosttarget is += positive (or perhaps always ? That could trick some unaware users).
- -16 or -20 kPa could be reasonable, depending on how good/powerful/fast the actuators are and how one is willing to tune boostcontrol
