Wideband!















Well thats the Wideband O2 installed.
As can be seen here from a cold start things start pretty lean then richen up substantially until warm and things drop into closed loop.
The LC-1 NB02 simulation is very erratic compared to the smooth stock results.
I might need to mess with grounding wires. Though preliminary checks showed little to no difference. I do however need to calibrate the Wideband properly as its LC-1 stock. Ive had to order a USB to Serial converter. Hopefully that should be in the next day or so.

I can now start AutoVE tuning which basically scales the VE table so that commanded fuel equals actual fuel. This then means that you can do without PE mode and use the custom OS to command specific fuel ratios at any RPM and MAP point. So far my part throttle is pretty good, but Ive been running with no PE or enrichment for a while and avoiding full throttle, so hopefully things will start moving pretty well once I get it the VE table sorted out.
