Gunsons gastesters

[dern]

Can't seem to get the ph search function working to find the answer to this one but has anyone got a gunsons gastester (not professional)... is it any good?

Thanks,

they're OK for the money but if your're chasing the last 0.02 CO% to get under MOT limits forget it.

They'll get you somewhere near and certainly good enough for basic set-up

I had the basic one many years ago.
Was kinda ok but a bit plakky and not very easy to get a stable reading off.
When it worked it was ok, and when it didnt i kicked it over the shed.......(makes mental note to use shoes with steel toecaps next time!)

I was going to buy one for monkeying about with older engines (mk2 golf gti) which I guess should be putting out about 2-3% co2 and also (mainly) for getting my bec with sva limits which is below 0.5%... would it not be good enough for that?

Cheers,

Mark

Yeah itd do for that. Used to get my car thru the MOT with it!

I used to own one, you have to keep doing a free-air calibration to get good results, you seem to spend more time calibrating the box rather than the carb.
I now use a wide-band lambda, but even a narrow band is better than the gas tester in my opinion.
