Stage 1 widebandlambda
« on: September 07, 2015, 03:48:54 AM »
The more i read about me7 functionality the more I ask myself the question if a wideband lambda probe is necessary for a stage 1 tune.
Without changing anything regarding fueling calculation tables you wouldn't need one.
Isn't it enough to log idc after adjusting load and ignition tables?
At partial load the narrowband lambda will do his job and will keep u safe.
At wot, so with open loop, me7 calculates based on maf readings requiered fuel for desired lambda.
So if idc is still good you should be still safe.
Please correct me if Iam wrong.

Sure, you could probably be fine without it. But, what if something happened?
You should be tuning ANYTHING with a wideband. Carbed, FI, NA, whatever. Fuelling is your biggest safeguard and you don't want to check and just hope everything's okay?

You can do that way, sure, but you will never know real AFR.
Use at least Innovate tailgate Wb02.

You do not need a wideband on a file with stock hardware.

You are assuming the stock hardware is functioning correctly. That is a bold assumption.

It's based on the assumption that people ensure their vehicles are operating within normal specifications before tuning. Another bold assumption given the current trend.
