Gastester in the News
Rider magazine EGA Hooray Exhaust Gas Analyzers Page 1 Page 2 Motorcycle Consumer News July 2002 Hot Rod, 1993 Customer Profile Scott at May's Sport Center in Sturgeon Bay Wisconsin has purchased several Gastesters over the years to tune motorcycles and ATVs before they leave the shop. They also sell and install a jet kit and the Gastester helps them tune the low speed setting for optimum performance. Scott said that Gastester is a cost effective alternative to 4-5 gas analyzers. Thanks Scott.

Welcome to the world of tuning like you never thought possible. Now you can tune like the pros with an affordable and accurate exhaust gas analyzer that takes the guesswork out of tuning or use a high tech air fuel ratio meter based on a Bosch wideband O2 sensor with microprocessor control that lets you measure air fuel ratio while driving. Truly a breakthrough in performance tuning. Gunson tools are legendary in the U.K. where they have been helping the do-it-yourselfer tune and maintain their vehicles for decades. You can stop tuning by ear and start tuning your car, truck or motorcycle the professional way with an exhaust gas analyzer that's proven in 10 years of customer use. Just ask Ducati Richmond. Gastester works! Gastester measures carbon monoxide the principal indicator of air fuel ratio and combustion efficiency. I've been selling Gunson tools since 1991 to motor sport enthusiasts like you that want to tune their rides for top performance. I use what I sell and can answer your technical questions about tuning and product selection. But don't ask my competitors tuning questions, they're order takers and not tuners. I stock all Gunson products imported to the US. If I can't get it no one can. Check the ads above. Four and five gas analyzers cost thousands of dollars and are overkill for the do-it-yourselfer. With Gastester you get nearly the same results as the expensive gas analyzers at a fraction of the cost. It's almost a no brain'r. Read the reviews to see what others are saying about Gastester. Product support is only a phone call away. But please AEP customers only. Tech Edge offers fresh new technology that lets you measure air fuel ratio, RPM and other performance metrics for analysis on a PC or handheld device like a Palm Pilot. The O2 sensor can replace the existing narrowband Lambda (O2 sensor) or used at the tail pipe as a sniffer. All Tech Edge meters use cutting edge microprocessor control for high accuracy and fast response time. |

Whether your passion is cars or motorcycles, Gunson has the tools that make engine tuning easy and straightforward. Gastester and Colortune help you tune like a pro by taking the guesswork out of engine tuning. Colortune is easy to use and gives you a visual indication of the air/fuel mixture based on the color of combustion which does not vary. Gastester measures percent carbon monoxide, the principle indicator of air/fuel mixture and engine efficiency but results may vary with ambient conditions. I supply a table, an AEP exclusive, that lets you convert from percent CO (useful for emissions testing) to air/fuel mixture. If your engine has one carb per cylinder consider Colortune first. Whenever you are setting the fuel mixture you must measure the exhaust gas produced by the carb. This can be tricky on multi carb application since there are usually only two exhaust pipes. Some cars have exhaust header ports that you can connect Gastester to giving you the ability to measure and tune individual carbs. If you can see the top of the spark plug or can use a mirror to look down into the plug then Colortune will work well. If clearance is tight or line-of-sight is blocked then go with the Gastester. To tune individual carbs with a Gastester you must be able to sniff the exhaust stream from either the tail pipe or from a port in the exhaust header. Some people are using a Riv-Nut kit available from Snap-on to create an exhaust port. Check

Maserati article
where the author describes tuning individual carbs using a
Gastester Digital. The author made adapters rather than using a
Riv-Nut kit. |
