Diagnostics equipment advice anyone?
 

Hi, I have come to the conclusion that I need to get equipment to measure co / emissions and air fuel ratio. Would appreciate some feedback from experienced users.

My goal is to adjust and tune my carb and injection systems. I would like to get an instrument that could do both co & af but it is hard to find something at a nice price.

I am considering the Innovate (I or II) for the AF and perhaps ebay for an older heathkit or similar analog analyzer for the co/emissions.

Anyone have recommendations on other / better / combi instruments?

Tuning
 

So you have a carb and cis ? Must be pretty cool looking :D:D. Have you cosidered taking the car to shop with a dyno and PC interface ? Most of them can get you the data you're looking for and even help tune as well as recommend jet changes.

A gunson gastester will measure CO and not cost an arm and a leg. You can find them on eBay, not sure if you can even buy one new anymore. It uses a probe you simply stick up the exhaust pipe, perhaps a plus for you if you want to use it on a lot of different cars.
The LM1/2 are AFR meters that use a wideband O2 sensor. Would be harder to switch between several cars. These lend themselves more to permanent installation in a single car. The benefit there is that you get a continual readout of your AFR as you drive.

gunson colortune is worth having imo. coupled with some sort of fancy schmancy exhaust analyzer you can probably get pretty darned good.

Gunson's are still available, and from the many ebay ads, the price has increased. About $200-$250 new. They're accurate, but are only able to measure idle and off-idle CO.
