So I had stock injectors on my car w/ HFS-1 installed. I had the trigger set to come on around 20psi, depending on the gear/rpm, etc. It worked great. I spent the last few days dialing in my new FIC 1050cc injectors. I did a few wot runs on just pump gas to test my low boost map, and it was suprisingly dialed-in. Flip on the DDS and wot....surprise! No alky!

I wasn't worried about it, thinking I must have bumped something while messing around with the car over the last week, maybe I bumped something....then I get to work this morning after logging more WOT runs....my PEAK idc is now in the neighborhood of 58%....alky is triggered by IDC %....before peak IDC was 105% on just pump, 127% on alky....DOH!

A quick spin of the dial in my DDS junction box and voila, tire-shredding alky fun is restored

Just a note for anyone with alky installing bigger injectors....CHECK YOUR TRIGGER POINT!!!

 

Thanks for the heads up!! I'll be installing mine next week!

 

good thing to point out, people can easily overlook this.

 

Ya, I probably would not have noticed if the change in injector size was not so big. I went from stock scaling of 513 to 1008, and my new injectors were actually flow-rated at 1072cc each. Going from stockers to 850's might not be so noticable...
