Wideband signal ground goes to Megasquirt sensor ground. If the wideband has no sensor ground like a bunch of other widebands (classic Uego, Innovate, PLX etc.), you then ground the negative wire where MS is grounded. So to recap. The X- Series have a chassis ground for the controller and 02 heater and a sensor ground for the actual 02 sensor. Thank you very much!
So to recap again, the White Analog + from the AEM-X is connected to point 21 at MSPnP2, and the Brown Analog - is connected to point 22 and NOT to point 5, was I right? Thanks
I think you are referring to the stock MAF that comes on the car? You will not need the MAF if you are running a megasquirt and WILL need the IAT installed for the ECU to properly determine engine load. The megasquirt comes with a MAP sensor in the enclosure that requires you to run a vacuum line from the intake to the ECU.
@@johnmarco5017 I loaded a base map from trubo kitty that had all of the appriopraite trigger settings for my car. If you're talking about verify spark timing, I used a timing light attached to cylinder 1 with fixed timing set at 10 degrees and verified that the timing markings on the main crank pulley lined up. What car are you installing this on?
I think there is a way to use the MAF, but there aren't many resources to figure out how to implement it. Because the MSPNP2 includes a MAP sensor all you need to do in order to implement the MAP sensor is install the GM Intake air temperature sensor. This has the added benefit of allowing you to remove the MAF which creates a large intake restriction. So for around $30 (for the GM IAT) you can improve flow and use the Megasquirt how it was intended.
I wired my O2 sensor directly to the DB37 connector. The wires from the AEM X-series are Brown (which should go to signal ground/pin 22 of options port) and White (which should go to O2 sensor input/pin 21 of the options port on MSPNP2)
I don’t understand how to wire the O2 gauge to the megasquirt. If you’re getting power from that, why would you need the buzzers power? Also I’d like to see how you ran the wires through the trans tunnel.
The power for the gauge comes from the buzzer, the signal output from the gauge goes to the megasquirt. I laid the wires on top of the carpet, but under the armrest.
The ground at the buzzer is already tied to chassis ground, which is already tied to the Megasquirt. Since you're running a power to the buzzer it simplifies routing to also tie your ground there. The positive and negative of the wideband analog output signal is separate from the power and ground for powering the gauge itself.
@@HardwayLearning well I took my power from my power windows option on my car can I take the ground from there to the back of the head or were ever it is on the 1996 next to the throttle body
@@Brizzle_718 is there not a ground at the power window? Otherwise you can take it to the chassis ground on the Megasquirt options port or use a ring terminal and bolt it to a stud anywhere on the car that has exposed metal.
I got three pins available 20,21,22 20 and 21 have a single wire while 22 has two wires spliced . Which wires should I use in that case? I bought a second hand turbo kit and got everything scattered Can I run all my wires to the portal connector? And which wires get spliced together like with pin 22
@@bryanrojas7993 the white wire (pin 9) of the wideband must go to pin 21 of the options port. The brown wire (pin 10) of the wideband should go to pin 22 of the options port. You will not use pin 3,4,5 of the wideband. Whatever else you have connected to those pins of the options port of the megasquirt I'm not sure 🤷♂️. You could have other sensors sharing that signal ground (pin 22 of options port) and that is fine. You cannot share that input though (pin 21 of the options port). Pin 20 of the options port should be used for your intake temperature sensor if you didn't use the OEM harness and you want to wire that to the options port and change the input in your tunerstudio file.
Yes, the stock O2 connector is still on the back of the head. It is no longer needed because the new O2 sensor runs to the wideband controller. Then the analog output of the wideband controller runs to megasquirt.

Can you please do an in depth video on wiring the red, black, yellow, brown, etc. wires to the Megasquirt? I’m really confused man.
And what’s that square white thing with the white wire?
Cool rope lights.
Thanks!

That is correct
@@HardwayLearning Thanks a lot! The same was received from DIYAutoTune today so it's a double Yes!
Hey, I'm fine with doing this and reinstalling the bung on my new header later?
The o2? Just swap the wideband onto the stock location. Or are you talking about your intake temp sensor
how did you calibrate the x -series ? I don't see the x-seires in the wideband option box
I did custom calibration and used the voltage values that are in their manual. 0.5V = 8.5 AFR and 4.5V = 18 AFR
@@HardwayLearning and has that worked? Cause I did that to but to no avail
@@TheEventMain sounds like you might have wired something wrong. What is the AFR reading on the gauge vs what tuner studio says?
i have a 4 wire map sensor, can i delete that and install a IAT? also my pinout says my stock map sensor has a built in IAT in the sensor.

Can you give more detail why you cant use the maf and what you need to do to instead of a maf?

The manual also lists a blue wire, is that the wire you connect to the stock o2 sensor connecter?
I wired my O2 sensor directly to the DB37 connector. The wires from the AEM X-series are Brown (which should go to signal ground/pin 22 of options port) and White (which should go to O2 sensor input/pin 21 of the options port on MSPNP2)

Did you directly connect the gauge to megasquirt so your gauge matches the same A/F readings as megasquirt?
In Tunerstudio you have to select the correct calibration in order for your AFR in Tunerstudio to match what your Wideband controller is outputting.
i have a hard time with the grounds if you ground the black one to the buzzer how its sharing chassis ground why not all ground to megasquirt
The ground at the buzzer is already tied to chassis ground, which is already tied to the Megasquirt. Since you're running a power to the buzzer it simplifies routing to also tie your ground there.

Where’d you connect your brown wire after?
You want the brown (pin 10) of the 10 pin connector on your X-series to go to signal ground (pin 22) of your mspnp2.
I got three pins available 20,21,22
20 and 21 have a single wire while 22 has two wires spliced .
Which wires should I use in that case?

Yes, the stock O2 connector is still on the back of the head. It is no longer needed because the new O2 sensor runs to the wideband controller. Then the analog output of the wideband controller runs to megasquirt.
