hej
info..
ms2, pcb 3.0, daugterboard...
har sat boardet op til at køre med hallgiver. virker også fint på simulatoren..(den er sat til pnp) men da jeg så skal til at wire det op ud til sensoren kommer jeg i tvivl.. giveren "steller" men skulle der ikke komme en spænding ud på ben 24 (5v) (gør der ikke) for at hallgiveren skulle kunne "stelle" det signal ind til boksen.. rigtig?
ben 7, har jeg forstået som det "bare" er en stel, hvis man skal bruge det. rigtig?
skrevet på grundlag af dette..
To use a Hall sensor, optical sensor, or points trigger, you connect the signal to the same input pin (DB37 #24) as the VR sensor
og har også kikket på MegaSquirt v3.0 PCB Schematics (over tach indput, self)
på forhånd mange tak

Tror jeg har fundet ud af det.. 
The MSnS-E modification for the 7-pin HEI is a simple and effective improvement for many set-ups. It requires changing two jumpers, and changing one resistor. This circuit supplies 5 Volts to the input circuit (and optoisolator LED) and uses the ignition module (such as the 7 or 8 pin HEI module) to ground the LED. The LED is guaranteed to receive 5 Volts this way, and the module is only required to sink the LED current (~4 milliamps). This results in more reliable triggering for many people. On a V3 main board:
Remove the jumper to OPTIO IN, and jumper OPTO IN with a wire to one of the +5V vias in the proto area,
Remove the XG1 to XG2 jumper, and jumper XG1 to TACH SELECT (do not jumper XG2 to anything),
Replace R12 (390 Ohms) with a 1K Ohm to 2K Ohm resistor (1/4W).
rigtig?
