Battery Compensation

[fizban]

Hello,
Is there any way to change battery compensation? I have noticed that when my A/C is on or fans are in high speed, voltage goes down to 12.7~ and my EGO correction goes to 112%~ , at idle.
Thanks..

It sounds like you have not good settings for your injector opening characteristics

Base Setup> Injector Settings> Injector Voltage Compensation Strategy

If you have good data on your injectors, you can easily use the simplified table

Thanks,

I am sure i don't have good settings.
I have RC engineering 750cc injectors.
This is the info i have:
10v - 1.36ms
11v - 1.12ms
12v - 0.92ms
13v - 0.76ms
14v - 0.63ms
15v - 0.50ms

my settings are (i didnt change the original settings):
Injector open time @13.2v - 0 us
Injectors effective rampup - 960us
injectror rampup voltage compensation - 4080 us
injector voltage compensation - 256us

What is this us measurement? How to i translate this?

no one knows?  ???

In newer firmwares you can change injector timing traditional to simplified, then you can use the voltage dependent times.

I am using 1.1.64 right now.
Its not only the open times i that have from RC - there are 4 types of data to insert in VEMS.  Is there any documentation how to configure this?

Newer firmware releases have features that could easilly help you with what you are trying to achieve.

have you tried the help screens? simply press F1 when looking at the configuration window you want to know something about. again, these help screens are better described in later vemstune releases
