ECUflash Increment Changes When Tuning Injector Scaling and Latencies

[99OZDSM]

Been researching and preparing for my first ceddymod/ecuflash tune. Ran into a couple questions about dialing in my injectors.

1. When I tune my injector scaling, if I either need to increase or decrease my injector scaling, how many increments should I increase or decrease it at a time?

2. Almost same question but regarding injector latencies. At what increments should I need to increase or decrease my injector scaling at a time?

I understand I need to raise injector scaling if AFR is too rich; lower injector scaling if AFR is too lean. And also more than +5% fuel trim low then raise injector latencies (throughout whole table) or lower latencies (throughout whole table) if below -5% fuel trim low.

Bottomline, I need to know how many increments to change injector scaling and latencies while tuning. Thanks guys.

set scaling first and base latencies. do a few WOT pulls. make sure AFR on tables matches your AFR on your wideband. if its off, redo scaling.
Now for latences, let the car idle for like 16 minutes once warmed up while logging like the site says. then change them by .005 at a time. i usually drive my car around town for like 20 minutes while logging then change the latencies.

Already have that link printed out. I'm going to set everything above 100 load to 10.5 on my ecu fuel map and match my actual WB gauge readings to it.

So how much should I scale/change my injector scaling at a time? I will set my base injector scaling to 550 for my RC 550 injectors. Should I add or subtract 10 at a time? 20 at a time?

Ok, so .005 changes for latencies, got it. Thanks man.

Depends how off it is. Sometimes 10 sometimes 50.
