I was just thinking because i want to replace my truboost with just a boost gauge and wanting to keep it looking like the AEM Wideband i have i could get the AEM 35PSI boost gauge which has a 0-5v output,

I could wire that into the ECU and use the correct scalings and it will work just fine correct?

Does anyone have the scalings for the AEM 3.5Bar Map Sensor? Here are the volts per pressure details

V - Pressure
0.5 = -14.7
0.75 = -11.575
1 = -8.45
1.25 = -5.325
1.5 = -2.2
1.75 = 0.925
2 = 4.05
2.25 = 7.175
2.5 = 10.3
2.75 = 13.425
3 = 16.55
3.25 = 19.675
3.5 = 22.8
3.75 = 25.925
4 = 29.05
4.25 = 32.175
4.5 = 35.3

And also the Formula for EvoScan Logging for this MAP sensor too please would be great

cheers

 

I have just read that the AEM 3.5Bar sensor is the same as the Kavlico 3.5Bar sensor so i dont need scalings but the EvoScan formula would be good thanks

This is good value i can replace my boost gauge and get a MAP sensor for $200

 

Just looking at this.. I own a JDM 8GSR. It uses a 3 plug ECU, not 4plug as per Evo 8MR and 9..

Would the pin numbering still be the same? I can still use pin numbers 81, 73, 92??

 

Pretty sure a 3 plug was an evo 9...

See this attachment

Accoding to this..

pin 42 is +5v
pin 46 is ground
pin 92 is the mdp sensor input

 

Thanks mate.

Yeah, the JDM Evo 8GSR's were definatly 3 plug. Are they 4 plug in the US?

Im also looking at hard wiring in a o2 sensor. Where should I be wiring that? I want to log AFR's.

 

Just read the attachment pdf and look for the front/rear o2 pins should be outlined in it.

 

^ JDM E8 GSR does not have a rear o2 Roadspike...

How do I setup Evoscan to log from MAP and o2?

 

There is nothing to setup no matter the configuration the MUT protocols will log the same no matter what model you have. Evoscan is already setup to log o2 and mdp/map.

 

here's a pic of the ADM manifold for anyone who's interested. as you can see there's no provision for a MAP sensor. Bring on my new Rev3

 

you can get an adapter for the sensor with a tail then connect via a pipe to the manifold.

 

AC80, I also have an ADM Evo 8 and I would love to see how you got the MAP sensor in there. I need to do the same mod on mine so any advice would be apreciated!

Where abouts in AU are you located?

 

Not me bud. I bought a Rev3 manifold from MAPerformance which has the provision for the MAP sensor. I imagine thought that you'd be able to drill the OEM mani where the map sensor ought to go on ours

 

OG, attached is my JDM 3-Bar sensor mounted after drilling and tapping the intake manifold. It's do-able, but not easy - apparently. I got a shop to do it, and they made a tool to feed through the throttle body to catch the shavings/filings instead of removing the manifold.

 

Are there any disadvantages to this method?

Using something like THIS

 

nope just have the pipe as short as possible
