Apparently, when your wideband dies...

By this of course I mean that megasquirt is making adjustments based off of what the wideband is reading. Which is why, when it took a ****, so did your tune.

What you really should do is take a few hours, disable closed loop all together, and fine tune your driving to be in the AFRs that you want. THEN turn closed loop back on. This way the ECU will only need to make minor corrections if any at all and you will have better driveability and better gas mileage. Not to mention, if your O2 sensor takes another **** all you have to do is turn closed loop off again and you're back to not washing out your cylinders with $4.25/gal fuel.

This is what it's supposed to be doing.

But I can't remember how to get into those settings, #1, and #2, I can't tune and drive.

datalog, then tune the car using the log. As long as you can read all the parameters right, you can do it that way.

ill get back to u in a min about turning O2 correction off.

#1 I can't help you with, lol.

#2 I do all the time. You just have to drive, datalog, and then park. Make adjustments from what your datalog says, then drive some more. Or, get a buddy behind the wheel and just have him toot along around town for you.

Ok you go to Basic settings - Exhaust gas settings. Then where it says "active above RPM", you change it to what you want the RPM to be when the EGO correction starts working.

Megatunix looks so much nicer than Megatune.
