Re: ID1050x dead times or fuel multiplier

So a high dead time will briefly cause rich afr before cutoff because the injector is being cut too late? So if i reduce dead time it will fire the injector sooner and also cut the injector sooner than a higher dead time?

Re: ID1050x dead times or fuel multiplier

Thank you for your help and patience. One last issue i am having with the dead times is my fuel over run cutoff is going really rich, like 11.5:1 before cutoff. I read one of your posts in another thread about reducing dead times until afr is flat until cutoff. Is there any other way to fix the rich...

Re: ID1050x dead times or fuel multiplier

Could it be that i am expecting too low of an idle? My min idle is at 850rpm. It idles a perfect 14.7 afr at 1000rpm, but once it goes down to 850 rpm thats when it starts stuttering unless its rich. Maybe these injectors were not meant to operate so low? My fuel pressure is at 45 psi base pressure....

Re: ID1050x dead times or fuel multiplier

No, you need to scale the injector dead times so that they are around 1.2ms @ 14V. eg 0.00 8.09 10.11 12.13 14.16 16.08 24.55 2.19 2.19 1.66 1.38 1.20 1.05 1.05 These dead times put my idle at 10:1 afr. Pulled massive amounts of fuel, literally pulled about 400% and it only brought me to a 13:1 afr...

Re: ID1050x dead times or fuel multiplier

With IDs the stated dead time is less than the stock dead time. It could be that they are measured in a different way, but the bottom line is that the dead times need to be around 1.2ms @ 14V to work. I suggest scaling their dead times until you get 1.18ms @ 14V. Then re-tune any areas where the AF...

Re: ID1050x dead times or fuel multiplier

Thank you for your reply. Why is the required dead time so much higher than what Injector dynamics says. I guess i am a little confused. Also what about the stock injector/current injector setting. Does that have to be exactly 1000cc, or 1050. Im not sure I understand exactly what that does, isnt it...

ID1050x dead times or fuel multiplier

I have recently installed injector dynamics 1050x injectors into my all motor b series. With a little bit of tweaking of the dead times from injector dynamics website i was able to tune them very easily except for my idle. My idle is smooth at high 13-14:1 afr but when i pull fuel to get it to idle ...

Smooth fuel table or consistent AFR?

Everyone keeps telling me my fuel tables are not smooth enough. In order to keep a consistent AFR the fuel table will swing up and down in some parts, not even that rough in my opinion. None of the cells are crossing into eachother or anything like that and the car feels great. When i smooth the fue...
