AE101 4AGZE Cam Sensor Help

Post by myk »

Ok, so I have an AE101 4AGZE from Japan, which uses wasted spark and a cam sensor (G1,G2,Ne,G-)

I got a professionally built MS unit v3.0 with the extra conditioner circuits for the cam sensor.

I can't get the sensor to read any RPM or cause spark to happen, however when I spin the sensor the Spark Advance gauge changes and the "FIdle/Spark" lights up.

If I set the codebase to Neon it actually reads a believable RPM, however does not spark.

I tried adjusting the blue pots on the board to get the senor to work. Each of the sensor's triggers are around 150-700 ohms.

I don't know what to do.

Any ideas?

And yes I did wire the sensor directly to MS. I checked the wiring several times and it cannot be wired incorectly.

the extra conditioner (lm1815 I'm assuming?) could be bad... I've had this happen on my setups that use a second trigger when the second trigger conditioner is bad.

Just a sanity check:

You should have the following setup:

Codebase: wheel decoder

Wheel decoder settings:

12 teeth
2nd trigger
no missing.

And you should have trigger/return settings and trigger angle that make sense for your setup. I'm not sure how the cam sensor is installed stock.

Thanks for the help.

Yeah, I have Codebase set to Wheel Decoder and no other.
12 teeth, no missing, 2nd trigger
trigger angle = 77 + 22.5
(10,4) tooth triggers
active edge? (set to rising) (don't know which to use, but I tried both anyway)

I realized that I never connected G- to ground, so I just wired G- from the sensor and from MS to ground.

Still reads no RPM.

Try turning the two variable resistors on teh board all the way counterclockwise until they click.

Also, that trigger angle seems a bit high... although that wouldn't cause you not to see rpms.
