"I did also notice that the resistor pack was VERY hot when i touched it "

Does anyone know if the resistor pack should be hot? i have never touched mine after a run, in all these years!

Just been for a run in hot weather. Remembered to try the resistor pack for heat afterwards.

The resistor pack should NOT, repeat NOT be getting hot. It should be engine bay airflow ambient.

Therefore maybe worth changing it?

BUT...if the injectors are being told to fire randomly and with crossed signals, the resistor could be heating up so it may not necessarily be bad...correct?

Hi Jake,
could you solve this meanwhile?
Needless to say - I got the same problem.
Please help.
Thanks and regards,
