FIC 850cc Scaling Assistance

Greetings,
I have searched the topic and also looked at the AEM injector spreadsheet. I just installed a new set of FIC 850 and I am having some trouble scaling them with ECU Flash. Basically my Wideband reads very lean (21+) at idle. Can someone share their latencies and scaling for these injectors? Thank you so much in advance!

WOW! no one? I did not think this was this hard. No one is running FIC 850cc injectors well tuned that could kindly post their scaling and voltage latencies? The ones in the AEM spreadsheet posted is this forum were not good starting numbers for me for some reason (very rought and lean idle).
Thank you in advance for your help!

I just did FIC 950CC's and wound up going with 700 on the scaling and 1.5 times the AEM values for the latencies. Might not be the right way to do it but it smoothed out the idle, it was going way lean like you are saying. Hope that helps.

Great! Thank you guys as always. I will give this a try. I ended running by new injetors with the stock 560 injector settings and it idle just perfect. Of course, I know this is not recommended so as soon as I get a chance I will start logging the fuel trims and dial the new 850cc as much as I can.
Thanks.
Alex
