They sounded good in the Oshkosh booth so thought I would support a small Canadian company. Good for 3.5 years, 450 hrs in my 78 Cheetah. Then between stops, the display morphed from the 4 cyl into a 6 cyl display with incorrect temps. The factory said it had gone out of calibration. Their flat charge bench fee was $350 USD (despite being in Canada), plus $16. parts. Total $430. w shipping both ways. No sympathy from the company which sells the unit cheap up front, and then grinds you when they have to fix their loss of calibration. Wont fix it again..will go with a JPI next time.
