I made an optical pickup for an old Suzuki engine. It was glorious. Just a phototransistor, infrared LED, mosfet and JB weld. VASTLY superior to the magnetic pickup. All that magnetic noise and hysteresis just goes away and you get a beautifully clean signal. In that case it even worked with the stock encoder wheel. You can even park it right next to the stator on the dry side of the crank. If you're having signal issues I highly recommend going optical.

What I'm hearing is that the Microsquirt doesn't have a zero crossing detector. This was a point of contention very early in Megasquirt history. Al didn't want to use the LM1815 off-the-shelf zero crossing detector "because he was told it was going to be EOL" and so the MS didn't get a VR interface. However, you could make a perfectly serviceable discrete Zero Crossing detector with an LM139. Meanwhile, the LM1815 is still readily available 20 years later, in fact I see that DIYautotune sells them!

By adding a resistor in parallel you are just decreasing the overall input impedance of your controller. The voltage stays the same. By adding a resistor in series with a controller input you are creating a voltage divider and increasing input impedance. To reduce the noise you could insert a low-pass filter, which would filter everything above highest engine frequency.

@thebigmacd

The VR sensor has fairly high internal resistance (on the order of 1kohm), so the parallel resistor also drops the voltage at the input.

Glad the solution isn't just to throw resistors at wires and crossing fingers

I went through the same thing when I was using a Life Racing ECU with a stock Audi 1.8T sensor. The resistor thing sort of works sometimes. Ultimately, the best answer was buying a nice Magnetti Marelli Sensor and using it with the stock 58 tooth wheel

Many years ago I had MicroSquirt, and the cam sensor (VR2) circuit couldn't see the low voltage that the cam lobe to OEM sensor produced when cranking on the starter, yet the OEM ECU could. I ended up using a diode, but later units had a a revised VR2 circuit that was more sensitive. There was a unit made by IMFsoft in the Czech Republic that had rpm programmable VR voltage clipping values to cope with the range of AC voltages generated by high revving engines.

Learned a lot here! Good show :)

Grinding down the teeth reminds me of a friend who used a wooden chain tensioner for his timing chain when he pulled the head on his Datsun. He couldn't get the chain tensioner out so he had the brilliant idea of hacking away at it with a wood chisel and vacuuming out all the chips. Then he wondered why he had no compression in one of the cylinders, when he put it all back together. He pulled the valve cover off to find a chunk of wood wedged between the valve and rocker arm. And a whole lot of chunks of wood in the oil pan.

Excellent work and quality entertainment! Thanks

Don't remove the oil, add oil and rub it all in. The top of the shoe is now water repellent. Genius!

One of the few things I remember from mechatronics class "don't let the smoke out"...oh and Butterworth filter is a funny name (no clue how it works anymore).

Wiping the rest of the shoes was also my instant thought as I saw the oil spilling over them. Hey, that's an improvement. Now they are even water repelling 👍

this needed a quick clip at the end with you posting to the "forum"

Would adding a coil in series with the sensor fix the problem? That would lower the voltage at high frequencies but not at low frequencies. You could also add a capacitor in parallel or build a more complicated filter out of these components

Love the barfing oil sequence

In one video you asked for tips on which tools you should buy... I'd suggest you get a medium/cheap oscilloscope... Then you can save a lot of time on guess work what signals your sensors return and where they pick up errors or or the resistors change the signal. Rigols are quite good bang-for-the-bucks

Amazing forward thinking to have that oil return window! It cleans the starter gear and speeds up an oil change. 🤯

I just love your antics, I think I'd be barfing food out my nose if I ever had dinner with you ha ha.

Best description of magic smoke ever!

Neat. To me, this seems like signal acquisition and conditioning issues - if it were I I would design a board that can actively convert the less than ideal sensor signal and “re-generate” or send a buffered “ideal” signal to the ecu. The tricky bit would be to make sure that there is no phase shift, or if there is, that it is consistent through the rpm range so it could be adjusted for… just my .02!

@zgrb

Жыл бұрын

This seems like a pretty good solution; also, maybe if the whole issue is that the threshold needs to climb with RPM, it would just need to be a variable resistor that could change with RPM? All of this is easier said than done though

@hammondeggsmusic

Жыл бұрын

@@zgrb Yeah, though perhaps in a more “active” sense - eg perhaps the rpm is converted into a control voltage that is used for a comparator to track the right signal from the sensor to derive the pulse from for instance. The issue with the resistors as is, appears to me to be about providing the right impedance to the ecu - an active buffered solution would be a powered device that monitors the sensor and “re-generates” effectively an “ideal” signal to the ecu. By using a lower impedance driver / buffer and a constant pulse magnitude over rpm, I don’t think the resistance to the ecu would be as critical over rpm range. Would be a fun project to mess around with though for sure!

@redcargarage

I agree that sounds like an ideal solution, but another tricky bit is making sure the signal conditioner is consistently fast enough. I'm wondering if instead of an active conditioner you could use some form of Schmidt trigger. Not sure that would be any better though.

I could get it to run but it just didn't feel right. I finally figured it out it was a 124 ignition module after an MSD box failed.
