The flywheel has 57 + 1 long tooth.
Hello Guest, welcome to the initial stages of our new platform!
You can find some additional information about where we are in the process of migrating the board and setting up our new software here
Thank you for being a part of our community!

Yes that was a volvo flywheel. You could try cutting the long tooth back off and reversing the polarity of the VR sensor, or make a plate that matches the profile of the Volvo Flywheel (this is the same issue that happens on 850 manual swaps, certain year flywheels require you to reverse the polarity of the VR sensor for Motronic to know whats going on...counting holes vs counting teeth.)
It appears that you modified yours in a wrong way:
If you count the holes you have 59 actual holes and 1 missing hole. That is if you modified your trigger wheel as shown above. It's difficult to tell from your pictures how exactly you did modify it. The signal from that modified one will not be similar to the stock L2.4 flywheel.
Many thanks for your visual reference, it made it much easier to comprehend where I had gone wrong
What did you fill it with? It needs to be magnetic steel (or iron) for the VR sensor to read it properly.
I also don't know what the proper distributor rotor setting is for LH2.4, relative to TDC. If anyone has a pic of the flywheel w/ sensor @ TDC, and of the correct rotor position, I would appreciate the input.
EDIT - do you have an opinion on the placement in terms of gap / tooth @ 90 degree mark?
But that is really just based on memory. I have no way of verifying that right now. A picture of the stock system with engine at TDC would be helpful here.
EDIT: It appears that the Volvo manuals state, that the ECU determines TDC to be 90 degrees after the passage of the long tooth. So that would mean, that first finding TDC, then turning engine 90 degrees backwards, and then adjusting your trigger wheel so that the sensor tip is at the ending edge of the long tooth, should set your system up as stated on Volvo literature.
The tricky part is what exactly that means - centered over the edge, just past the edge
Leave stock maf, the 012 also messes with timing..cant remember how but i think it advances a bit. A less but still possibly dumb idea, have you tried just putting the 30lbs in and seeing what happens? I think its too big a jump for lh2.4 to adapt to but youve already got them...and its a better idea than an 012 on na car
