Modifying Narrowband output for LC1
I got my LC1 installed finally after sitting on the shelf for a few months, and spent some time tuning my AFPR. Then it occurred to me that I have the ability to modify the narrowband sensor output to tell the ecu whatever I want it to (I.e tell the computer it is running more lean or rich than what is actually happening). So I started to mess around with the settings a bit before it got dark. A typical narrowband sensor outputs 1v@14:1 and 0v@15:1, however I have my ecu seeing 1v@13.0 and 0v@14.5
The result was less lean tip in and quicker spool time, along with running a bit richer at idle, but i could care less about running rich right now as I just wanna be faster for the autocross tomorrow. Also I ended up tuning the AFPR to run 55-57 psi at idle and the rise adjuster is screwed most of the way in. Air fuel ratios in boost are about 12:1 which is a bit rich for 5 psi, but safe i think.
