*wideband auto tune and/or closed loop feed back

Get asked a lot if I'm ever going to implement this and the answer is no. I've actully written and tested the code to do this (and it somewhat works) but decided its smarter to not release it.

Main reason has to do with a false promise that it'll work 100% without issue. Most guys want a true plug and play solution for their cars without having to do any tuning. The honest truth is, there is no such thing. Anyone who tells you anything different is trying to sell you something. Each individual car will need its own unique tune. On this platform there are lots of guys who take major short cuts to save $$ and it ends up causing some mechanical issues that make tuning difficult. There is just no good way to write software intelligent enough to compensate that well for all the ghetto/lazy/poor setups out there.

Another reason is liability. The hardware and code can only react so fast and that reaction is based upon feed back from the sensors. This feed back information from your sensors is only so good... If you got any kind of misfire from your motor, the readings from your o2 sensors can be inaccurate thus the code will not compensate correctly. People are quick to blame the "tuner" for mechanical failures and its hard to prove fault one way or the other. I feel its in my best interest to avoid giving some "Internet mechanic" a tool that can be used against me.

Third reason is to force people to actually get their hands dirty. As I said before, each car needs its own unique tune. Doesn't matter how identical your setup is to another car. The general chaos of combustion and voltage feedback isn't as consistent as many want to believe. Tuning a car really isn't difficult at all. Some people are just intimidated by all the features and reading required before getting a good grasp on what's really going on.

I will say that there is nothing wrong with using the 1V narrowband output from your wideband in place of the stock narrowband sensors. Just keep in mind that widebands are finicky devices and have very short life spans so be aware of this if you do decide to eliminate the stock narrowbands. I am working in a plan to have the closed loop code target leaner AFRs for better gas milage but what's difficult to get people to understand is the closed loop subroutines function off feedback and response, not a target AFR (that's why the code cycles the narrowband readings).
