Ok, I am reading my injector duty cycle from my AVCR and it says at around 1k rpm that the duty cycle is around 14%. Here is the setup. Hondata. Aeromotive pump, etc. 75lb injectors. 44psi fuel press.

Also, does it matter which side of the injector goes to the ecu signal and which side goes to the resistor box?

Thanks, Jason

 

is this at idle? or are you revving it to 1000rpm. 14% duty cycle i know for certain is a bit on the high side for idle. Idle should be under 10% for sure. I'm sure more guys here can give more insight

 

Yeah, the idle is around 900-1000 and the duty cycle is around 13-14%. That is the reading on the AVCR.

mines like at 1.4%...your idle might be a bit high. Do you have a load on your engine...(AC on? headlights on??)

 

No load at all. Even with the idle that high....would it still be around 13% duty cycle?

And your 1.4% is read off of your AVCR?

Jason, what does your duty cycle read in the hondata?

Yeah, I would look at this too. Mine is like 1% or something really small. If you want, I can look at my datalogs and tell you. This is with 800cc injectors though.

Really though it is WOT that you care about Injector duty cycle.

 

I'm still using my 450cc's and read the duty cycle off of my Power FC (which is similar to way the AVC works)

AC does create quite a load and so does the headlights....AC more than anything else though
