I installed these injectors on my supercharged RSX yesterday (going to be turbo'd after next weekend). My idle has been funky. I can't find the dead times for these injectors ANYWHERE on the internet and EFI has no contact information on their website. Anyone running these care to help out?

problem solved. just needed to be tuned out

 

 

 

Are these saturated/high impedance injectors like ID1000s, or what?

FWIW, I've ended up between 1.2 and 1.25ms on both my RC750 saturated injectors and my current 96lb Low-Z/Peak and Hold ones. If you set the dead time too low it will totally screw up your idle.

 

Contact Miller on here, i think he owns EFI Wizard

 

They are high impendance. I've been using the ID1000 dead time chart
(below) and plugging in the different psi. I started with 55 but was advised to go 40 or 45 on a returnless system. I tried the 45 out but my but when i driving, push in the clutch. it spikes up to 2000 sometimes and the idle hung a little high (1200~) I put the 50 in and car seems to be running okay. idle likes to hang high (1100~1000)



Who?

 

It's Chris Miller, one of the current kings of the sport compact world, and a funny bastard. I think his screen name is "miller".

As for the fuel pressure comments, weren't you talking about injector dead time? Sorry if I misunderstood. Generally I think people tend to use enough fuel pressure to support the power they want to make with the injectors in use, and anything more than that simply taxes the fuel pump unnecessarily.

After that, you tune your VE table or whatever type of fuel table you have to get your AFRs right. Without putting in some correct dead time numbers though, your ECU won't be able to calculate the correct pulse width to make your motor happy, especially at low PWs like at idle.

So, what PWs have you been using? Are you saying that as you are adjusting your fuel pressure to try to make your tune work better you are applying the specified dead time from the ID1000 chart you posted?

 

They are dead ALL the time.
