wideband A/F ratio meter

[dastang2]

will one of these work on a carbed engine with no computers, i was looking at a mag and it had an ad that said works on any efi systems but what about carbs

Shouldn't matter if your carbed or not. EFI systems just really love wideband tuners because you can get a near perfect a/f ratio for any condition if setup with a proper computer.

so i can get one and a regulator and tune the reg. until i hit the perfect a/f ratio on the wideband

 

[Daggar]

Yep

With a carb you will have to do more than just adjust a regulator. You will have to try different jet sizes, different accelerator pump sizes....etc. Just like on a fuel injection car you can't just tune using the regulator. It is done by tuning the computer with a custom chip.

Exactly.

With a carb setup a wideband is a good tool just as it is on a EFI setup.

Only diffrence is on a EFI setup (the expensive ones anyway) if you have a wideband hooked up to the computer it pretty much takes the guess work our of tuning the A/F as it can automatically put in fuel take it out, extend pulse width of injectors, etc.

Some of the really nice setups have a wideband 02 on every exhaust port runner so you could get a perfect tune across the board not cheap but nice.
