There are two major differences. APT has taken the Lectron technology from the late 70's and developed the Smart Carb through 25 years of development sense then. They both work on the same basic principal, yet the Smart Carb is in other ways totally different. The two major differences are, #1 - The Smart Carb has the float bowl pressurization circuit. It is temperature and Altitude, "density altitude" compensating. The Lectron is not. They are a non sealed and vented carb, much like others. Not density altitude and temp compensating. #2 - the metering rod of the Lectron is a multi angle ground rod. Meaning the rod has to compensate for differences in signal. The Smart Carb has a flat rod. The signal is so correct and uniform from idle to WOT there are no metering differences. In one blind test, a single 38MM carb was sent to 7 different people from Canada and across the US to install and run. The "same carb", one at a time! The 7 bikes were all different, from 125CC to 500CC bikes. They all ran spot on with a total of 13 clicks between all 7 bikes. The Smart Carb being sealed and a pressurization circuit, apply fuel as per signal regardless of bike or size of engine. In current testing for EPA and OEM applications, the Smart Carb was 80% less in emissions than EFI, 13% better fuel economy, and 5 more HP.
I do not work for APT or get paid in any way. Ha! but there is not a question, the Smart Carb is the most advanced fuel delivery system available today. Period... makes the simple, "raw" EFI systems look pretty poor.
Got it!!thank you verry much! Makes sence now! Lectron with holtzman tempaflow and ATACC all in one,sweet!!now I want one!
