what latency voltage (4.6875 7.03125 9.375 11.7188 14.0625 16.4062 18.6768) uses on what rpm or load?

 

If you log your battery voltage in EvoScan, you can easily tell. Most of the time it's between 12 and 14V.

 

and for what other voltage use?

 

The latency accomodates differences in Voltage between car to car. It's not really dependent on RPM (At least at Idle. Voltage goes up a little with RPM's though. But, for the purpose of dialing in fuel trims (Specifically idle) you will be concerned mostly with the voltage your car is seeing under idle conditions).

What you need to do is log at idle what voltage your car is running at, and adjust the value closest to that voltage. (Assuming your Injector scaling is close to where it should be) Most of the time, you will be changing the 14.0625 voltage, but changes in the "surrounding voltages" 16.4062 and 11.7188 will also have effects, but not as great as the 14.0.625 voltage. Here is a condensed blurb from Razorlab I believe (Maybe someone else) on adjusting Injector scaling and latencies that I reference occasionally:


1. Choose an ECUFlash injector scaling number
2. Log trims at idle and cruise
3. If trims are roughly the same, but positive, then you need to lower your injector scaling number.
4. If trims are roughly the same, but negative, then you need to raise your injector scaling number.
5. If idle trim is more than cruise trim, then increase the dead time by increase the latency value.
6. If idle trim is less than the cruise trim, then decrease the dead time by decreasing the latency value.

 

tyvm!!!
but have one more problem, i have always short/middle/long fuel trim 100% (((

 

That means they're perfect.
