Finally I was able to use pin3 for 12v for Q9 and Q12 because of voltage spike and pin 4 for knocksense

I order the knocksense kit and it's suppose to be connected to MS2 on pin 27. But pin 27 is already use with my Jeep 4L IAC. Any idea?

Ms2 ground on the engine block and low impedance injector

When I run megalogviewer, I have voltage from 9V to 22V even with a brand new alternator. MS2 3.0

What can cause that?

Matt,

You're always right
Ground at the same place, same reading...

It was bad connection on pin 2. I changed the pin and now everything is working OK.

Thanks!!!!!

I have the EDIS4 setup. The RPM in my dash is not working properly. At idle sometime i have a reading and sometiime not. If i rev the engine, the RPM jump sometime but usually drop to 0. My RPM is plug to the coil using the diode bridge at the end of the EDIS4 page. If i use a test light grounded ...

Matt,
I suppose they have to be ground together and they are not.

I have a Innovate MTX-L wide band sensor. My set up in megasquirt is set to Innovate LC1 Default.
The problem is that i have a difference between the reading of my gauge and the one in tuner studio. My gauge is 1 point richer than the one in tuner studio. What is the problem and witch one is right ...

Thanks! Matt

I have the MTXL wide band sensor. What do i use on megasquirt??? DIY wideband????

Thanks!!!!

What i don't understand is that the signal come from the CPU. It flash on pin #21 but not on pin #22. U4 flash on pin #2 but not on pin #4. What can happen for the pin #22 to not sending a signal????

12V on pin 3 and 6 pin 3 is the neg.
pin #5 0.85V
pin #7 0.28V

and it flash on pin#39 and 40

Yes Matt i just did but same thing. Flash on pin#21 but nothing on pin #22

I have megasquirt II V3.0 and the injectors don't light on the stim but the led light on megasquirt. If i check the pin#21 on the CPU, it flash but i got nothing on he pin#22. What could be wrong???

I was finally able to get RPM. My problem was that i bought my DB37 harness from DIY and the pin #24 was a black and a white wire shielded. The first time, i hook the 2 wires to my pin#1 on EDIS. WRONG After replace the module by 2 other ones, i suspect the terminal and then i decided to change it ...

If i use the stim,i move the fine RPM pots clockwise and the RPM jump from 0 to around 2500 and then go back to 0 and after that going to around 170. Help me chase the ghost.

The strange thing is i got RPM when i use the stim but not in the car. I try to switch the VR wire but no spark when switching. And i test the continuity of the wire and the wires are OK.
