Default DIYPNP 1.5, only 1 RPM reading, dont start

Hi Guys,

i installed today a DIYPNP on a Friends car and i wont start with that.
We installed also my DIY on his car, and it fired up right away.

Have anyone a idea, what can be wrong with the other ?

Please help us.

Thank you

composite log will log the CAS inputs... it will let you know if that signal is being brought in correctly.

hm, i showed there but i didnt see anything intersting there, nothing was showing on the right side, now we have the diypnp no longer installed, so i cant check it again.

We also have checked the Spark output, but no sparks coming.

it wont spark unless it gets a good CAS signal. and why i want you to look at the composite log during cranking.

Using the wrong firmware type does weird things to the ignition. Glad you got it cleared up.
