I'm going to install my new ID1000 injectors and was wondering how to set that up in the Kpro III. I have a decent fuel map already and taking out the RC 750s.

So I'm wondering do I set the injectors as 1000cc then upload?

 

Yes and no. Putting the new injector size inside your calibration will automatically scale your fuel map, but it will not be precise because RC's and ID injectors perform differently. It should be good enough to get you to a tuner, but I wouldn't use it as a permanent solution.

 

I wasn't sure if there was a way to input the new size (1000cc) without scaling. What is everyone using for dead times?

It's going to a tuner really soon just thought the inputs for injector calibration were straight forward and the ID website doesn't give data for Hondata. The Hondata website gives a method for the inputs click here but wasn't sure if there was an accurate table with all the values floating around.

 

The dead times sheet should have come with the injectors. If you don't have them, ID has them on their website.

 

I loaded the dead-times from the ID website and input 880cc for the injector size. It idles much better than the RC 750s - no fluctuations. I noticed my fuel pressure at idle is about 37 psi and the fuel damper is ticking - I don't remember it being that low at idle and the ticking is new. I am going to install the FB 340lph fuel pump this weekend.

 

What is your base fuel pressure? Lets say its 60psi, use the ID values for 70psi. This compensates for the vacuum inside the intake manifold. EDIT: noticed you mentioned your fuel pressure is 37psi. Try starting with the ID listed dead time values @45 psi.

Tune injector size as specified in the Hondata link posted above.

From my experience, Hondata doesn't do a great job of scaling the injectors. I still had to make modifications to my main fuel maps.

 

I have an AEM FPR so I can bump up the pressure. I wanted to see the difference the ID1000s would make at idle. Prior to replacing the RC750s the fuel pressure was 55psi. So my fuel pressure dropped ~15psi - interesting. My AFR at a cool crank and hot cranking is 12.0 then steadies out to 14.4 after 30 seconds. When I give it a good rev @3000 rpm, the AFR goes back to 12 then eventually settles to 14.4 again in about 30 seconds. The rpms at idle are very steady which was impossible with the RCs - it stays exactly at 850 rpm. I'm going to install the FB 340lph fuel pump before I start making big changes to the fuel map.
