Hi guys,

My Kraftwerks kit is finally being installed tomorrow. I have been trying to work out if any extra sensors are required to get optimum results from the kit when it comes to mapping the AEM EMS v2?

Do I need a boost sensor? How would the ECU understand boost levels without it? I've seen many installs where guys just have a wideband and nothing else.

I was considering:

1x
AEM 0-50 PSI (3 BAR MAP) Pressure Sensor Kit, stainless steel 30-2130-50 (to monitor boost)

1x
AEM 0-150 PSI Fluid Pressure Sensor Kit, brass body 30-2131-150 (to monitor oil pressure - I have an AEM fuel rail so this will plug straight in)

1x
AEM Water / Coolant / Oil Temperature 1/8 NPT Sensor Kit 30-2012 (to monitor oil temp - this will go in a sump adapter)

I also have a Mishimoto radiator to install which also has a 1/8 NPT port for use with a temperature sensor - will this be needed since I read the AEM EMS v2 ECU works with the factory coolant gauge?

I have already bought the UEGO Wideband which I think is essential!

Are these sensors easy to wire into the AEM EMS? I assume I just need to run some wire to run the cables? I plan to monitor these using an iphone/ipad app.

Where is the best and more accurate place to T into for boost?


Thanks for your help.

You dont NEED any gauges for your supercharger. But its highly recommended to monitor whats going on. I believe the AEM determines boost levels from the Map sensor.. but i could be wrong

 

You'll need a 3-4bar map sensor depending on how high your boosting. Oil temp and pressure are a very good idea. Factory temp gauge works fine with the v2 unit. The AEM serial gauge is good for displaying just about any value the EMS reads.

 

This is perfect, you'll want either or 3 or 4 BAR MAP sensor, the factory won't read accurately passed about 8psi IIRC.

This is confusing, if you're going to use the for oil pressure, it won't go into your fuel rail. You'll want to find somewhere to tap into oil pressure. I believe many people use the VTEC solenoid.

This is fine, I know a few people that use the plug adapters. They just say it can be annoying when changing oil.

I don't think you'll need to tap into your radiator. AEM V2 uses the factory sensor and location. It should read automatically.

Good, you can either wire it into the AEM as another sensor or just keep it independent. AEM will use the primary o2 sensor as well.

I've read some of them can be a pain to wire into the AEM, but you just need the scehmatics (should be on here somewhere) and some pin outs. (you can buy online)

You don't need to T into boost as the AEM will read off the MAP sensor. Unless you want to add a mechanical boost gauge, you won't T anything.


Honestly, with a wideband, oil pressure, and oil temp, you'll be good to go.

 

You should at the very least get the inline wideband controller.

 

This could be helpful to you

Besides the normal ones, wideband and MAP, I ordered 2 fluid and 2 air temp gauges yet to be installed. I'm doing the air ones in these locations air intake to blower, exit of blower pre-intercooler. I've got a A2W setup so I'll be putting the fluid ones on each side of the heat exchanger. I'll be able to get a good handle on my heat soak and what changes help get my AIT temps down. Probably overkill, but sensors are extremely cheap (relatively)

 

Thank you for the helpful replies! They were perfect - what a great forum!

 

I bought my Kraftwerks kit with tuning so it already comes with the 3 Bar MAP sensor

So if the AEM v2 will read boost off the MAP sensor then there seems little point in getting a seperate boost sensor?

Think all I will need then is:

Oil Temp
Oil Pressure
and Wideband.

 

I have a 2.5 bar AEM MAP sensor and it reads boost just fine. AEMdata reads it in PSIg already so no need for another boost sensor. I replaced my O2 sensor in the test pipe with a wideband one. Also you will have to get the AEM UEGO controller or the gauge kit or you won't have anything to plug the wideband O2 sensor in. If you buy the serial data stream gauge you won't have anything to plug the wideband up to (ask me how I found this out

I have Defi gauges for Oil temp and pressure. Both are good, but if you have to pick one I would do pressure, you already have water temp if needed.
