Review on 🔍 G4125 Gastester Digital by Gunson by Corey Singh

This exhaust gas analyzer works very well, the only reason is that it doesn't get 5 stars, it's not very accurate. The California Motor Vehicle Authority has very strict requirements, and among those requirements is an error of 0.5% much. However this is an essential tool for older vehicles to measure emissions, it does not measure other gases that are required but with low CO levels you will most likely have low hydrocarbon emissions as well. This tester doesn't guarantee you'll pass the DMV emissions, especially in California, but it will greatly increase your chances of success. A tester that guarantees DMV success costs more than ten times as much. The correct use of this tool, which is not documented anywhere, is to remove this CAT, then inspect the exhaust and make any necessary adjustments, then reattach the CAT before riding. for DMV, this will most likely ensure you skip outliers. The reason CAT needs to be removed is to get the most accurate reading possible since CAT captures most of the CO. The reading will not be accurate with CAT but even with CAT enabled it will help but your reading will not be accurate but this will help in the sense that if you have high CO readings with CAT installed you will most likely not be able to emit emissions. are governed by many regulations for governments, the only smog checks they do are official smog checks and that's something you only want to do after you set up a smog check and that's what this tool does valuable, most smog check sites won. Don't do smog check tuning, even if you pay them to tune your car they will only follow the official procedure and the official procedure seems like you have to fail first before the car gets tuned. I have used it in an e150 van and it works great on both petrol and propane. The plastic pipe melts over time, it doesn't withstand the exhaust gas temperature very well. Check the CO level with this tool and lower it as much as possible without engine failure. The mechanic-recommended %CO for old cars is too high for the emissions to pass. At the required DMV, an old car runs very poorly, but what fuel valve starvation is required today to skip emissions. As you tune in for better performance, no outliers will be published.2. The ethanol in fuel is very bad for your engine, but it's good for emissions, so it's a good idea to pre-use ethanol fuel for leaner emissions before going for the DMV inspection. Ethanol has very low lubricity and can damage an engine, but it helps reduce emissions, which is why many fuels contain ethanol.3. Use a clean, low-drag air filter such as B. K&n.4. Have clean oil in your engine, since part of the oil goes to the air filter where it is used for combustion, it is better for older engines to use oil with a higher viscosity.
