Restricted Use

I purchased this unit for use in my drag racing car to control the air/fuel ratio during a race. I've checked the RPM of the motor (requires a cable not included in this kit) and the A/F ratio and it runs and works well most of the time. The software was basic but useful, and I didn't find any major bugs. I also bought a heatsink for the sensor because in a race car the temperature can get too high for the sensor and shorten its lifespan. However, this is not what you need to replace a…

Great tool for carburetor tuning and height adjustment, better than reading plugs.

If I could give these 10 stars I would. I've been working on engines for almost 50 years and I'm still working on vintage cars (ie with carburetors). All this time I used the plug and read method with satisfactory results. I live at 7500ft now and love to drive from here to the mountains and back in a day or two. Some vehicles stop more than 10,000 feet from fouled spark plugs. This device, along with an additional exhaust pipe tool, taught me in an hour what I had been guessing for all these…

  • Air to fuel ratio

I was never able to get the laptop's USB connection to work properly, it worked for a few minutes and then shut down so I only had to read the display while driving and was unable to use the ACM Write down information for later reference. . The SD card slot is

Needed for a fine tune 78ft Toyota carburetor

1- Gave 5 stars for 'thickness' because it really didn't matter how thick it was. I'm not even sure what they mean by "thickness" for this product. 2- I gave it 5 stars for "Accuracy" because as far as I can tell it is very accurate. 3- I gave 4 stars for "Easy". for the installation" due to the work required for the installation and welding for the exhaust system. I had to mark the place for the "plug", remove the exhaust system and take it to a professional welder. .Don't have to 4- I like…
