3.3 ProCal3 Diagnose Tab
The ProCal3 tool may also be used to read any diagnostic trouble codes (DTCs) on your
Cobra Jet. Go to the Diagnose tab and use the buttons to read or clear any codes. Click
on the Key On Engine Off (KOEO) and Key On Engine Running (KOER) self tests to run
these in order to find all codes. Note that the engine needs to be on for the KOER test.
NOTE:
Launch assist is not a smart traction control device. It is a closed
loop spark modifier with no active feedback.
