I found the answer to my problem in the Megasquirt II manual. The hall sensor was not noisy but the power wire feeding the hall sensor was so I put a capacitor on that wire. Also I felt that since I could not avoid having the wires to the spark plug wires I replaced the distributor wires that go to ...

http://i59.tinypic.com/2cdxtnp.png [IMG]http://i59.tinypic.com/2cdxtnp.png[/IMG] This is a graph taken this morning. I seemed to have most of static taken out of everything but the motor RPM's Can anyone tell me how to smoothen out the RPM graph.. Green is the engine RPM Yellow MAP Red Throttle sen...

I don't know how to post the actual log. In fact it took me a while to figure out how to post this screen shot. The white line in the upper part of the graph is the RPM and the Green jagged line is the throttle position sensor. This engine is in an airplane where the throttle movements are slow or s...

The upper part of the graph the white line is the RPM and the Green line is the throttle position sensor. Does anyone know if the RPM's and throttle position sensor suppose to be more smooth and not so jagged at this? http://tinypic.com/r/2mx0lf8/8 http://i60.tinypic.com/2mx0lf8.png Robin Megasquirt...

I also had a tach signal problem once. I had to add a 12v pull up on the signal line going to the controler. First I used a electronic ignition called Pertronix and then when my motor dropped dead I thought it was the Pertronix so I changed to points and there too I had to add the 12 volt pull up so...

MS II 2905 software, Note that I found the reason my coil quit. The gear on the end of the crankshaft spun moving the timing 120 degrees from top dead center. The MS II works great it was the engine that gave up.. I purchased a new crankshaft and installed it and now the engine is running again.

I found my answer buried in the Manual....Cooooool

Megasquirt II with 2905 software. I am using Tuner Studio. My question is I don't know were to set my AIT, "Air Inlet Temperature Based Fuel Correction" Is there a default setting I can use? I accidently erased mine thinking it was the cold start setting,, Oops.. I am starting over with a ...

I hooked the LEDs straight up to the coil, Positive and Negitive. So each ignition event the LEDs would flash. My latest adventure however is that I dis-connected the MS II from the ingnition and ran the ignition from the distributor as it was from the factory. Now I have a great spark to the plugs ...

Yes you have to add a jumper to make it work also you will need to make a jumper going out too if you want it to control the ignition. I believe it is in detail in the mamual about step 65 or so. There is more answers to this somewhere on their site, I think under wiring.

If it starts and then runs a little and dies, then you need to adjust the warm up enrichment.
I got everything running on mine then the mega controller quit running my coil so I lost my spark. Hummmmm.....

I have found that after cranking the engine over several times that the LEDs I have hooked to the coil quit flashing but I still have a tac signal reading 250 RPMs. I also checked the LED ignition light on the Megasquirt and it is flashing even when the coil LEDs quit, but somehow it quits sending t...

I'm running MS II with code 2.905, Corvair 2.7 Liter air cooled engine, Pertronix Ignition timing run by MS II Everything was running great but I did have to set the dwell to 3.9 or it would run rough. I have verified that the power is only on when cranking. Do you think I burned up the coil some ho...
