Worked exactly as advertised..
I suspected I had a rich mixture so I bought this. I followed the instructions and I adjusted my mixture until I reached the target CO spec (for an older Porsche 928) and now the car runs better than it ever has before. I recommend.

Decent analyzer; seems a tad expensive
The unit is a bit cheaply made (plastic), and not robust at all. However, it seems to work OK. Has sufficient length power cable and the plastic exhaust tubing is long enough. So far the plastic tubing hasn't melted. The CO readings seemed to fall in line with what the NJ state inspection station reading for CO was. I have only used it twice, and will revisit to adjust my rating at some point down the line.

Works well - read the directions!
Works well for tuning vintage autos, but read and understand the directions! Proper calibration is key - this isn't a toy, you have to think about how you are using it.

Cheap build quality for the price
Calibration knob was broken out of the box. Very flimsy build quality. Didn’t get to open it til it was out of the return window.

It takes a while to learn to use it, but once you do it works quite well.

OK for the money
Requires a lot of warmup time, about 30 minutes, to get accurate readings. It's also a bit flimsy. Not bad for the price paid.

No se, no se si funciona :)
No se, no se. No se perquè no hi han sensors de més marge. El sistema aprofita un sensor de petita dosis i fa passar una part diluïda del fums de l'escapament per fer una lectura "indirecta" que no vull dir menys precisa . Tot això ho se perquè me'n volia fer un amb el mateix principi, perquè com he dit al començament, no he trobat sensors de lectura directa. Ni idea si marca bé, no tinc manera de comprovar-ho si no és un laboratori.

Co messer
Super. Hier stimmt das Preisleistungsverhältnis vor allem für einen Hobby Schrauber, habe damit den co-wert von neun, drei auf drei, null genau einstellen können am Vergaser
