Hi all, 1st post here. Would appreciate you guys could have a look at MSQ and tell me what I'm doing wrong.
I'm getting settings errors in the MAP phase detection and Tacho output.
The engine is from a 1987 BMW M6 US, s38b35, 6 ITB's single coil, 60-2 toothed wheel, magnetic crank sensor, TPS and MAP
Thanks
Chris

Please read the tooltip on the "Cam Input (if used)" setting. You don't want it set to "MAP sensor"

Your tacho output is giving an error because you have configured it to use "FIDLE" but you already have "FIDLE" set as the idle control output.

Also, consider upgrading to the current firmware version from the Downloads page.

Thank you James, that worked perfectly.
After setting up the tests with JimStim the only pots not responding is the RPM and fine rpm, also nothing is showing when in Diagnostics&High Speed Loggers. Composite , Sync Error and Tooth Logger are all blank. Even when I connect the MS to the actual engine I am not getting any response in Diagnostics & High Speed Loggers when cranking the engine. I have tested the magnetic 2 wire sensor with a voltmeter and am getting 3-7 mv when cranking the engine so I think the sensor is okay.
Any advice is appreciated, here is the updated MSQ. Also, I tried updating the firmware but I will have to try later as it was 'transferring data' for an hour and a half and still wasn't done.

What sort of sensor are you using for RPM input, and how is the board configured for it?

[grannyknot]

The sensor is a magnetic BMW pulse generator from a 87-93 7 series E32, two wire.
Not really sure what you mean by board configration except I have the ignition options set for toothed wheel, 20 skip pulses, rising edge, going high, single coil, JS10, 60 teeth, 2 missing, 84 degrees tooth #1 angel (14 tooth gaps x 6 degrees)
Current MSQ is on the 3rd post.

Apparently the MSQ didn't post properly, I'll try again,

[Matt Cramer]

What MS2 variant is this, and how is the board hardware set up for RPM input?

[grannyknot]

Not sure if this is the info you are looking for but,

MS2357-C MS-II PCB v3.57 SMT, with jumper for VR input, modified for single Bosch BIP373 ignition output on pin 36

Yellow wire from crank sensor going to #15 Tach terminal on the MS relay board
Black wire and shield from crank sensor going to common ground for all return wires and relay board ground.

Is it able to get an RPM signal on a Stim?

[grannyknot]

No

[grannyknot]

Some progress, got the RPM working on the JimStim, I needed to go inside the 3.57 box and switch over JP1 and J1 to VR sensor, engine MAP gauge is also working now and I managed to download the current firmware but lost all my settings in the process. Luckily there aren't so many yet.
Still not picking up any signal from the crank sensor while cranking the engine, the gap between sensor and wheel is .90mm
the width of the wheel and sensor is 8.5mm.
When I test the crank sensor while cranking the engine with a voltmeter I'm getting 3-7 micro volts, is that what it should
be or is that too low?
Thanks,
Chris

About half a volt AC is what I'd expect.

James

[billr]

Is that low (3-7 microV) signal with the sensor disconnected from the harness?

[grannyknot]

About half a volt AC is what I'd expect.

James

Sorry, I'm measuring in DC milivolts, I doubt my voltmeter would even register AC that low.

[grannyknot]

Is that low (3-7 microV) signal with the sensor disconnected from the harness?

That should be 3-7 milivolts DC, and now that I think about it the signal coming from the sensor would be in AC wouldn't it? I guess I need a more sensitive AC voltmeter.

You have a VR sensor correct? I noticed that you have Noise filtering turned " Off " in your Ignition settings. Don't VR sensors and Magnetic sensors usually require Noise Filtering to be turned " ON " and adjusted to get a strong signal?

Not really no.
The noise filter is there to filter out noise on the input.

[BlackBird_SR71]

I should have said " Clean " signal. If he did have noise on his VR input, would that not affect the RPM signal...considering that he's getting one on JimStim and not one on the car?

Edit: Of course it could be just a faulty VR sensor. MS VR pickup documentation mentions 20mv AC minimum during engine cranking. R56 and R52 pots have to be adjusted to individual VR's as well. Is that correct?

[grannyknot]

I turned on the noise filter and the tach period rejection and did a run on the jimstim composite logger.
The signal still looks erratic and when I switch over to the real time display it is almost impossible to control the rpm with the adjustable pot, it goes from 0 -7000 rpm by just touching the turnscrew.

here is the msq.

This 2nd log is still in composite logger but with tach period rejection turned off, now the rmp pot is working perfectly but the signal still looks strange.

And here is the log with MS hooked up to the engine cranking to test for signal from the crank sensor.
