Invent Jetronic ignition control for Mercedes

VulpesIgnis

Excellent.
Which wire from the ECU should I use to control the coil with?
Is the voltage input for the hall effect 5V or 12V?

JHM

Hall sensor should be powered with +12v
ECU use EMUL wire to steer the coil

VulpesIgnis

JHM
Hall effect wire signal should be DH, right?

JHM

VulpesIgnis
Yes.
AN should be disconnected

VulpesIgnis

When installing ignition control in an M103 Mercedes engine do I have to swap the 3 teeth flywheel for a 60-2 teeth flywheel?

JHM

VulpesIgnis
No, it's intended to work with 3-teeth flywheel.

VulpesIgnis

Would it work with a 2-teeth flywheel form an M102?

JHM

VulpesIgnis
Yes, 3-teeth for 6cyl, 2-teeth for 4cyl Mercedes

VulpesIgnis

Perfect, how much can I advance my spark using this method? I will be trying to advance it to around 35 degrees max

JHM

VulpesIgnis
You're free to set any angles in range 0 - 50

Hey. Does this support coil on plug system ?

JHM

Inzzz
no, this kit is designed as close to stock as possible.

VulpesIgnis

Sorry to revive an old thread, how do I feed RPM signal back into the cluster?

JHM

VulpesIgnis
I guess that feeding hall sensor signal will do the trick

VulpesIgnis Did you get your m103 to spark with this Hall effect sensor and Coil? waiting for someone to actually have it running

VulpesIgnis hello did the cluster work with the new hall signal?

kpraz I am waiting for a mate of mine to install an M103 in a W460 to go ahead and install the spark control system, I will keep everyone tuned and i'll try to write a guide aswell!

Larttis

Has Anybody done this yet, im doing it in couple of months?

JHM

DocAlfa
cluster use hall-like signal from EZL, so it should work like before.

VulpesIgnis Hello. Did You managed to install spark control system from Invent to Your MB?
