Inlet Camshaft Bank 1 Position Diagnostic

[dochka]

Hi,
After Flashing the JRR Firmware into the M130 ECU installed in a Mitsubishi Evo 7 with a Adaptor Loom, I've got this warning...
What is the cause and how to fix it ?
Attached some pics

Thanks for your input

That is indicating there is no signal from the Inlet Camshaft Bank 1 Position sensor. You might check that's it's plugged in, inspect the wiring. If that doesn't find anything, then review the configuration and determine what resource is configured for that sensor, check that it you have continuity from that pin on the ECU all the way to the sensor.

It's possible you could have a configuration issue -- say that sensor is really a hall-effect sensor, and yet it's not configured with a pullup control turned on, or the threshold isn't above zero or something similar.

You will likely find all of these on the worksheet "Initial Setup 2->Cam Control Inlet".

Did this only start happening after you updated the JRR firmware, or is this the first time you've gotten the engine running on this firmware?

It's a wiring issue, the M1 is not receiving a signal on the allocated Universal Digital input.

It only started happening after the firmware update

The engine is a 4G63 from a Mitsubishi Evo 8, with no variable valve timing..
How does it "Cycle Lock" if it doesn't receive the Camshaft Signal ?

Thanks

Does it have the Sync sensor wired in and configured? The 4G63 engines have a separate sync sensor to the inlet cam position sensor.

[David Ferguson]

If you don't have VVT, you could just de-configure that resource (change the position resource to "Not in Use") to eliminate the diagnostic error.

Yep, thanks
I did that

Yes,
I also read the sync sensor voltages in the MoTeC M1 software and think they're right

Thanks
