I just got some FIC 1120 injectors and would like to see the scaling/latency some of you run on 91 and E85. I looked in the super merge thread but there were only 2 posts on these injectors. Is the included data sheet any help?

 

I was just looking for this information myself. I just ordered the FIC 1120's and plan to run e-85 when I get them in. I found some information that may be helpful:

These posts should give you a starting point to get the car to run. Then from there just log your fuel trims and adjust accordingly.

My plan is to swap injectors while still running 93 octane. Once that looks good, I'll switch to e-85 and adjust.

 

Thanks but I figured it out.

 

What numbers did you end up using? I'm curious because I will be doing this in the next week or so.

 

This is what I have now and the trims are close together on E85. The 975 scaling is for 91 but thats probably off just a bit since I havent ran 91 since I changed my latency.

 

great, thanks for the info!

 

Just an FYI, I used your latency values but set injectors to 1008 on 93 octane and it was pretty close. Idle trims at -12, cruise at -2. Thanks!

 

Try increasing latency to bring them closer if you want to. Scaling will have to be adjusted as needed.

 

Yea I'm fine tuning now, but I started with your numbers and got super close. Thanks!

 

Hi guys. How is ur fuel consumption on normal pump gas? I'm only doing about 14mpg on 98 fuel. Are these injectors v high in consumption or is it my tuning issue?

im running on stock engine with 270 Tomei poncam and FP red.
