Looks like it would work good? Lets hear your opinions.

Also, has anyone done this?

Matt

 

looks good to me, as long as your sure that you did it right...you might want to dyno verify it later on.

 

you would do all that to save 30 bucks?

 

There are some people that build this stuff for fun. Its a hobby.

 

yup its just ahobby its not about saving money. its about you learning things.

 

I know this is a remedial question, but what's the difference between this and a 300.00 wide band setup?

 

0-1v

wb 0-5v

 

std gauge 0-1v and displays rich for n/a cars, but not f/i. rich for f/i will be 11 or 12 afr while n/a cars 13-14 is rich.

wb is 0-5v which will allow you to read all the way down to 10 or below in your a/f.

a std gauge can read rich, but may still be really lean while turbo'd.

hope that helps.

 

There are a bunch of those. I bought a DIY kit on here but never put it on and now its at home.

 

I made one of thoes, if i can find it you can have it for the cost of shipping.

 

Are these accurate? I think I might get one of these....

 

They are as accurate as one you would buy. They all do the same damn thing. As long as you put it together correctly. Its as good as what you can buy. And can't be the experience and learning involved in putting these thigns together. I did this on my Rx7, with a volt meter and a One-wire O2 sensor. It was interesting.
