If romraider could have an easily configurable option to set up a sensor via the TGV wires that would be ideal. A menu to just plug in the sensor information would be all you need.

You could hack it yourself without too much work. Just wire it up and log the TGV sensor voltage. If you did OK in your math classes you can create a new conversion function in the logger.xml file that does some math on the voltage and gives you the result in AFR.

^It would just be nice to have a form pop up that would modify the logger.xml automatically. I'm sure I could figure out the scaling myself, but wouldn't it be nice to just have a simple form to fill out instead of doing it manually?

Before you spend your time recoding this, please investigate the success many people have had simply moving the stock oxygen sensor post-turbo... For some reason people are so reluctant to believe that it works well even when there have been several documented cases. I have even seen one working perfectly fine first hand. I'd just hate for you to do unnecessary work.

The ethanol sensor is a fantastic idea!

Does anyone know which two wires I need to splice into off of the maf sensor to hook up the GM IAT sensor???? I want to try and get this hooked up this weekend so I have everything working the best possible since I just got my engine running

I assume you are looking for a 2002 WRX... correct?
If nobody answers by tonight I'll look it up in the repair manual.

its the pin 27 of connector b135 of the ecu, dont have the color of the wires but this might help you. From the sensor one its going to be ground and the other to the pin i mentioned before. And you will need to re scale the sensor in the map. good luck!



If still need the color i will look into it later, when i get to my car!

I have the manual, I know there Are 5 wires And I believe someone said once before it was the brown wire and another one, im assuming I need the sheilded signal so im thinking sheilded signal ( which has a ground, and power????) Or just ground and signal????

Edit B27 is brown, doesn't say what it is, actually im looking in the 2002jdm sti manual, but most the wires are the same, and I have a jdm ver8 engine And complete engine harness, but I guess that wouldn't matter since the maf is part of the bulk head harness, either way B27 is Br and im thinking its also E13/E8, E13 being the sheilded wire and E8 being the sheild ground so basically power and signal,

Does anyone know what to rescale, and what to rescale it too????

Edit #2
Group d I believe is the GR which is green red but not sure why it wouldn't use the PL ( purple - blue) sheilded wire.

The shielded wire is for the MAF. There are only 2 IAT wires, and 3 MAF wires.

On a usdm wrx the maf signal wire is maf purple shielded wire. Then just find out which one is getting voltage and which is getting ground

Ok on the MAF Sensor Plug theres 5 wires.

Pin ------ Color ------ Signal/Voltage ------ Ecu Pin
Pin1 ------ YL ------------ 12v ----------Main Power Relay
Pin2 ------ BG -------- Sensor Grnd ------ 84/7
Pin3 ------PL ---------- Maf Sign -----------84/13
Pin4 ------ Br --------- AirTemp Sig ------ 135/27
Pin5 ------ GR --------- Ground -----------Ground Connector


See if that helps.

New features:

-NLTS - this will require a small amount of wiring. Luckily the clutch switch basically switches a ground to and from a relay, so all that needs to be done is your desired ECU input needs to be spliced into the GY wire on the clutch switch. By just splicing in and not cutting the wire, the clutch-in-to-start function will remain functional.

-Removed the MAX load table
-Included the ability to use positive or negative values in the MAP sensor offset
-Removed the user levels
-Coded in a "cut x from y" method for launch control and NLTS (to get a quicker more accurate RPM hold)
-DTCs can effect CEL status alongside KnockCEL
-Sparkcut Launch Control
-Ability to disable Defrost logic (if anybody ever had issues with using it as an input)
-Ability to target higher than 24psi (haven't done this yet but it should be quick)
-Fuel pump duty hysteresis (so fuel pump duty doesn't go crazy when you are right on the edge of the switch point)

and maybe some other random little things I forgot lol

Amazing. You are in the wrong line of work.

I agree, you should hire me to work at your shop! haha just messing, Im actually working on getting my mechanical engineering degree right now, but I hope to have a career that has some bearing in the automotive industry.

DOM is the man. I love how Subaru will show you a connector 5 pins label them 1 - 5 left to right then put the wires in the connector 1,2,4,3,5.

Damn, you're right. But, you were the first to use a non-Subaru IAT sensor on a MAF Subaru?

Jesus, how the eff did I miss that. I myself did this a month ago and I just looked at the wire colors.
