if it's working leave it alone
on my emanage ultimate i've never done a firmware update since installing it in 2007/2008
and now based on your experience i never will...lol
Using the global injector setting for scaling larger injectors should include special mapping to prevent 100% Duty Cycle input from the stock ecu to the emu at higher boost, maybe someone will know if this changes with firmware?
Short version of the emanage U Limitation -
If a stock ecu goes 100% input duty cycle the emangeU can't control the injectors, as it has no gap or variation in duty cycle input data to calculate injector output. Usually this occurs at higher boost and usually results in afr going very rich.

well not necessarily the firmware but the program. However the newer program only works with newer firmware. With that i get knock sensor workin and other lil logging stuff. But other than that it works fine.
