My AEM is on its way and that would be a good time to experiment with EGT on stock engine setup.
I just wasnot sure if AEM allows to select other ports to use as EGT input.
thank you.

Glad to help. If you have any questions getting things to work just let me know and I will dig up those old cal files to see exactly how I had it set up.

What's a good place to get switched ignition power for the AEM EUGO Dual-Channel controller in the engine bay? Seeing if I can have both ground and power in the engine bay rather than one in the cockpit and one in the engine bay.

Also, the 0-1V output returns real data right, so if I have the stock ECU (I don't, but my AEM which is not installed may be toasted, not sure yet though), I can run the 0-1V outputs straight to the stock ECU, yes?

Good info, Renner! If someone can detail what it takes to run K-type thermocouples for EGT, I'll include it in the 3/S AEM FAQ - or link to a page you provide or whatever.

I'm in for the info...as I too am switching over to the dark side... (AEM)

I'm sick of piggy backs... I have way too many... and its getting a little out of hand... time to do it the right way... (and sell off what I have now to pay for the new setup)

so... I too got a couple of questions...

what is the AEM wideband O2 UEGO controller - Dual Channel? this is not included in any of those kits right?

Anyway... what comes in that 3rd kit again... hahaha (Its so unclear... I'm about to ask them to give me access so I'll fix that page for them) It doesnt come with any of the Air/Fuel gauges right? just the sensors? if not then how many guages are needed just 1 or 2? other after market gauges will not work right? (like defi, apexi, blitz).

What about those other sensors... like the IAT (AEM Intake Air Temperature Sensor) and the EGT (AEM Exhaust Gas Temperature Sensor) the dont come with the kit also right? they are extra? and are they really needed?

And finally... once everything is going in... what other things are need to make the car work... I say this cuz the maf is not going to be there so we need different piping... what parts?

Dual AEM UEGO controller is a wide band contoller that connects two wide band O2 sensors to the AEM EMS. A gauge can be purchase seperatly that will attach to read the wide band.

I have a single wide band UEGO type AEM gauge. That is a gauge that has a controller built into the gauge and conects to a single sensor and can be attached to the AEM EMS. Since the wide band sensor has to be located several inches down stream it ends up in the down pipe just after the two pipes join together. So in my OPINION a dual chanel wide band is probably not needed. A single wide band controller seems to sense A/F ratios just fine in the down pipe after the gases are mixed together. Other people prefer the two O2 sensor rather than one however.

To eliminate the stock MAS and run Speed density set up you will need a Intake Air Temp sensor and a Manifold Air Presure sensor. When the AEM EMS knows the temprature of the air and the pressure of the air it can calculate the amount of oxegen the car is breathing into the engine. The EGT sensor is not absolutly needed but is a nice extra addition

When you remove the MAS and the intake tubes to the turbos you will need to replace them with Intake Air Tubes that have a filter on one end and then attach to each turbo. Dual intake tubes can be seen on the www.dejontool.com site. Other places also sell Dual intake tubes.

Ok i will be running 14b's both before i do fuel i want to get my car running on the ems first. I want to run with the map sensor, so could someone tell me which sensor and from were to buy them. I'll get the dual channel uego wideband 02, and i will have two egt gauges (apexi). Should i get a gm boost solenoid or stick with my greddy profec b ebc? Could someone also send me a base map so i could start my car and drive it with out boosting it, cause i have never used aem before so i'm a noob to this.

Ok, the red power wire on the MAF harness is a 12v switched ignition power source. Good info for anyone wiring in the dual-channel controller, then you can run the power and ground wires over to the battery side and the connections are pretty close together.

Looks like my EMS is messed though, will not connect to laptop, I'm running the narrowband outputs from the EUGO to the stock ecu for now. Looks like I'll be sending the EMS back to AEM to look at. I made sure the COM port was cool, tested the serial on the COM port, had the car in the ON position, tried cycling the power, nothing helped.

My IAT sensor is in the upper plenum right behind the throttle body. Since mounting it I have noticed that most people mount thiers in the Y-pipe. I'm thinking of putting a plug in the upper plenum threaded hole and moving the IAT sensor to the Y-pipe. I am also mounting a water/meth injector noozle in the Y-Pipe. Would it be best to mount the IAT between the Water/Meth nozzle and the throttle body? Or would it be better to mount the IAT sensor before the water/meth noozle and before the trottle body.

I'm concerned that the water/meth might throw the IAT sensor off.

Water/meth--IAT--throttle body

or

IAT--- water/meth---throttle Body.

which would be best for the speed density on the AEM EMS?

DONT use the basemap from aem for the stock injectors. TO MUCH TIMING.
