copied from aem. here is some setups for the map and iat and wideband, boost control. for newbies like me.


Initial setup / MAP, AIT, wideband, and boost solenoid wiring!

Follow these instructions to wire in your sensors. (30-1311)

MAP Sensor
There are 3 wires on a MAP sensor. It requires MAP signal, 5V reference, and sensor ground. If you're using an AEM MAP sensor: MAP signal is green or white, 5V reference is red, and sensor ground is black. The signal wire needs to be dedicated, meaning that should be the only wire making contact with that pin. The sensor ground and 5V reference wire can be tapped. Please follow the pin out below to wire in your MAP sensor. If you did everything correctly, with an AEM 3.5 bar MAP sensor, your MAP voltage (setup/sensors/map sensor parameters) should be about 1.6V with the key on engine off, with an AEM 5 bar MAP sensor, your MAP voltage should be about 1.3V with the key on engine off. Remember to select the correct sensor in your MAP sensor wizard.

91-93
MAP signal - Pin 53
Sensor ground - Pin: 72 (tap to this pin)
5V Reference - Pin: 61 (tap to this pin)

94-97
MAP signal - Pin 73
Sensor ground - Pin: 92 (tap to this pin)
5V Reference - Pin: 81 (tap to this pin)

Air Intake Temp. Sensor
There are 2 wires on a AIT sensor. Polarity does not matter. It requires AIT signal and sensor ground. Please follow the pin out below to wire in your AIT sensor. Remember to select the correct sensor in you AIT sensor wizard.

91-93
AIT signal - Pin 52
Sensor ground - Pin: 72 (tap to this pin)

94-97
AIT signal - Pin 72
Sensor ground - Pin: 92 (tap to this pin)

Boost Solenoid
There are 2 wires on a boost solenoid. Polarity does not matter. It requires switched 12V and PW2 on EMS. Please follow the pin out below to wire in your boost solenoid.

91-93
PW2 - Pin 105

94-97
PW2 - Pin 35

Wideband (this is for EMS without built in wideband)
If you're using 30-4100 (Gauge type wideband controller), 30-2300/2301 (Dual/Single channel wideband controller), or other wideband controller with a 0-5V output, you will need to tap the 0-5V output wire to the O2#1 or O2#2pin on your EMS. White wire on 30-4100, and orange wire on the 30-2300/2301. Please follow the pin out below to wire in your wideband.

91-93
O2#1 - Pin 56
O2#2 - Pin 55

94-97
O2#1 - Pin 76
O2#2 - Pin 75

Please reference our Instructions page for any EMS pin out or other instructions *Instructions and Manuals*

If you have AEMPro installed on your computer, the instructions and pin out can be found here: C:\Program Files\AEM\AEMPro\Instructions

here is the pinouts for the ecu

Can you control the AC fan with the AEM if the AC unit has be removed ?

[markoverclock]

how much is removed just the pumps and ac parts or did you remove all the electronics? if you removed the pressure switches then im pretty sure you cant use that to control the fans. but you should be able to wire in a relay and use a output for the fan.

Anyone have knock cal logs with:
Forged pistons and rods with 6 thou skirt clearance
Shimmed street cams
Maximal solid mounts

I have 6 knock cal runs on my new setup, all low boost low timing and man is it noisy past 7K.

[Import Power]

anyone?

If the rain clears today I will go to Piedmont and log mine if that will help you. No dyno just hard runs. I have the rev limiter set a 7K but I can up it for you for a couple of runs....

I am talking about knock Cal runs which I already did on your car
I have the noise signature from your runs right here. Nowhere near as noisy as my car.
As you say Bruce, I have the solid metal mounts. I think that accounts for some of the noise up top.

Good luck at the track, let me know how she does!

Post up a knock raw log.

it might make you cry and run away
seriously it's that noisy past 7K.

i have the knock raw and knock volts logged during the knock cal runs. they are at work. I can post when I get there.
