Hey, i got a small prob i reset my power fc to factory ecu mapping... My problem is i have 810cc injectors by deatschwerks i figured out the correct injector size correction but i don't no how to figure out the latency correction i have the formula(New Latency - Old Latency = Latency Correction) from what i understand is that the old latency for the 370cc sr20det injectors are .70ms but at what voltage is that? And also i emailed deathschwerks for the 810cc latency and he sends me this:

Volts latency(ms)
7v 4.1
8v 2.9
9v 2.3
10v 2.0
11v 1.7
12v 1.6
13v 1.4
14v 1.3
15v 1.2
16v 1.1
17v 1.1

I have no clue of which one to use to plug into the formula:confused:

thanks for the help!

Either 1.4 or 1.3 - .7 = latency correction

If your alternator is good and you are seeing 14v or high 13v use 1.3.

Latency is really only going to affect your idle and low rpm values.
