Question Regarding Choosing EMU For 2jzge (NA-T)

[2JZNA-T]

So would you recommend i ground the wideband to the actual chassis ? Or should it be in a pin thats listed as a ground ?

In the chassis along with the other grounds.

Ok will do. So but the IAT is going to have its ground on the EMU's "sensor ground " correct?

I think those are the only sensors i have to wire in from what im understanding. Apparently i just need to wire in the wideband sensor and iat sensor and im good. So really those were the only things i needed.


Thank you !! still reading the instructions trying to get a decent idea on how to tune and control everything. The guys at ecu masters told me they would load a base map for my engine so i can plug it in, wire in the wideband and iat and be able to drive.

When im looking under the instructions for the wideband it doesn't seem to how anything about using the analog for the wideband. But i may be missing something.

But i will put that 0-5v signal into Analog #1 and ground it at the chassis maybe on a bolt or something like that. And the IAT will be wired entirely into the ecu harness so its on an isolated circuit with the ecu.

IAT must ground at the sensor ground like all other sensors (coolant, triggers, etc...) if you are replacing an AFM or MAF on the 2J the IAT wires are probably on that connector, and you can just connect your IAT sensor where the AFM or MAF used to be. That way you don't have to run 2 new wires all the way back to the EMU.

The wideband can technically ground anywhere, and run the 0-5v signal to an available analog input. For best accuracy, ground it where the ECU grounds, if its anything like most toyota's its on the bottom of the intake manifold. I usually cheat, and connect it at the EMU.

Once the WB is connected, go into software/sensors/o2 sensor parameters, and select "external controller" then below that will be where you specify which of the 4 analog inputs you connected it to. And the calibration, as mentioned previously. If you didn't ground it where your ECU grounds, then you may have to play with the settings to get it to match your WB gauge.

Sounds interesting ! well that means i would need to find out which of the 5 pins in the MAF connector would be the right ones to the IAT signal. Also i already have the wires running through the firewall for the IAT.

Just downloaded the program on the site. and looking around. I listed the wideband input signal under analog #1. But i feel like the best place to put the ground for the wideband signal output would be to the ECU Ground because then it isolates the circuit to the EMU.



Now im looking at the injector setup, but sadly it doesn't have my injectors on the injector wizard, so i entered my injector cc but really i don't know what else to do beyond that.

They are listed as DeatschWerks 800cc in the software.

Ill put it as that then. Thank you !


I've been spending awhile here on the program learning about the ignition and setting things. Now im on a setup where i have to figure out whether my distributor is a VR or Hall optical sensor. and teeth and what not. Im searching around right now and trying to determine that information.

You guys have been a great help and i appreciate it so much. I can't wait to get my car running again !

I got a map from a GE, will check it for you.

Awesome !!

If possible it would be helpful to know some more about what i need to select for ignition info.

Currently i've been looking at all this stuff and trying to adjust and put in order the way i think its supposed to be. but can't say forsure. I may be wasting my time.

Trial and error i guess
