Small exhaust gas analyzer......

Where can I get a small exhaust gas analyzer? This is for just 2-3 vehicles, so I don't need no expensive, fancy setup. Not for a shop, just for personal use. Thanks

Exhaust gas analyzer

Good question. Kind of wondered about this myself. All of my vehicles have fuel injection which, naturally, comes with it's own exhaust gas analyzer. I'm forever on a quest to use the readouts that are available with the electronic systems and recently stumbled across a cheap system. Purchased an RCA tablet for $42, got an APP for $5 and it will read everything the F.I. ECU has to offer. Why can't this system just read the O2 sensor stuck up a tailpipe? I think all you are really looking for is the CO reading which is directly reflecting how close your system is to 14.7:1 correct?

So with a wide-band, 14:7 is best for idle?

The only inexpensive ones are single gas which is close to useless, you would need a 5 gas to be useful.

Wideband/narrow band O2 sensors are not anywhere near the same thing, but a wideband can be used for steady state tuning.

None of this is required unless you need to pass emissions.

Computer controlled FI systems attempt to maintain 14.5:1 as a goal during idle and steady state cruising conditions to maintain converter efficiency.

I think this is what you are thinking of. I built this about 1976 or 1978. It was manufactured by Heathkit. I have used this to tune a lot of carburetored engines. Too bad you live back in the ice bowl I would say swap me something Kool for it. that would be a long walk.

it was like 80F here today in Los Angeles.. there was snow last weekend as there was a massive ski jump set up in the the LA collisium but the snow was only on the ski jump. i was up next to the hollywood bowl today.. in fact i ate breakfast in the hollywood bowl parking lot.

if that 87 has an oxygen sensor.. its accessable with a wide band oxygen sensor or a hand held scope to check the air fuel ratio for smog..

toyotas also have a secondary accelerator pump diaphragm that goes bad.. its under the 3 screw cover on the side of the carb.

I use to use one to set my carb to pass emissions. worked GREAT till the state went from % of CO/Hydrocarbons to grams of CO/Hydrocarbons. after they did that, it really got hard to pass test.

More simply, you just need to search reviews about OBDII on the internet, then choose for themselves a scanner that you think is the most appropriate

Like my 3rd post states, it's for carbed vehicles, it's not for fuel injection.
