Thread: Overkill ECM/TCM - P0315 - Crankshaft Position System Variation Not Learned

No, this is read as, "Overkill is greater than Diablo." The symbol ">" stands for " is greater than", is typically used in math to show that one number or expression is larger than another.

This is opposed to the " is equal to" sign "=" which would state that something is the same or "equal" to another.

An easy way to remember it is that the > sign is a crocodile and it wants to "eat" the greater meal, it wants "more" food, so the open end or it's mouth is always pointed to the bigger one. If you flip it around, it reads "is less than" and is pretty self explanitory.

The = sign is memorable because it depicts exactly what it means, 2 lines that are the same size and length, they are "equal"

So this gauge can scan AND program the ECM?

On our cars, it can perform a case learn, turn the engine fans on/off on demand, and reset fuel trims.

Other than that it really just scans almost everything. You cant tune with it or anything advanced like that.
