Technology next to engine heat, poor ventilation, high voltage ignition and gasoline.
The environment for an EFI, in an AD truck, is terrible.

It's rare to create a new tech product that doesn't have bugs initially. Then it takes revisions (product updates) to get it right.

This is where smaller companies are at a disadvantage.
I'm in no hurry. My Carter YF and stock ignition works well.
There is no need for me to jump on the EFI bandwagon until a clear winner is known. Maybe in 10 years.

I look for comments posted at the Better Business Bureau and search the Internet for "Product Name" problems.
FI Tech is one of those listed at BBB.
