[Diy_efi] Fixed Frequency Injection

[paul w]

Hi guys,

I'm playing with a TBI system and experimenting with fixing the injection 
frequency and varying the pulse width, as opposed to the conventional 
technique of synchronizing the pulses to the engine and injecting once per 
plug firing.

My application is a generator, so the rpm is intended to be regulated to a 
fixed set point at 1800rpm.

Any comments on whether fixed frequency would work, and what the impact 
might be in terms of A/F control, stability, fuel distribution, etc?

Thanks,

Paul
