What kind of changes if any are required to run the IAC motor and TB with a ems?

Thanks.

I'd like to know too!

 

I will ask My mechanic he had a solution he uses on DSM but i cant remember what he told me but it works with the AEM and the Q45 tb

 

thanks

Here is all the information I've collected on how to do this:
Note: none of this is my own info, just information from other people.

Also, AFAIK the Idle Validation on the q45 cannot be connected to the Idle Speed Control on the EVO but I ran into another post by ifarted2which alluded to the contrary: https://www.evolutionm.net/forums/sh...&highlight=q45
ifarted2: care to enlighten us please?

I also have not been able to find the pinouts for the ISC connector... not sure if it's needed at all, but if anybody finds it can they post it please?

-------------------------Q45 info--------------------------------------------
The Nissan TPS uses two 3 wire connectors on it. One is on a short section of harness about 6 inches long and handles the actual throttle position signal and the other made to the body of the sensor is for the idle validation circuit. With the sensor standing up, the mounting tabs on the right side and the TPS wiring harness coming out of the bottom while your looking at it the top 2 pins in the connector made in the sensor body are your idle validation pins so disregard the bottom pin. Your TPS wiring harness that comes from the bottom of the sensor will terminate at a 3 prong plug and have red, white, and black wires in it. The wire colors correspond with these functions:

Red is the 5 volt input wire

White is the TPS signal wire

Black is the sensor return wire

With the connector lock up the white wire will be in the center, the red wire should be on the left, and the black wire should be on the right. My car is an 88 so I can give wire colors for an 88 Toyota Supra.

Brown is the E2 wire for the sensor return

Blue with a red stripe is the Vc wire for a 5 volt supply

Yellow with a blue stripe is your IDL wire for Idle validation

White with a red stripe is your VTA or throttle position signal

You take your brown E2 wire and branch it into 2 seperate leads. One will go to the idle validation switch and one will go to the TPS harness connector. You can put the one E2 wire(brown) on either the top or second post of the idle validation connector( the one made on the sensor body itself) and the IDL ( yellow with the blue stripe) will go to the other. Then the other E2 wire(brown) will go to the black wire in the Nissan TPS harness, VTA wire(white with red stripe) will go to the white wire in the Nissan TPS harness connector, and the Vc wire(blue with red stripe) with go to the red wire in the Nissan TPS harness connector.

The question I had for you is, does it matter how the box is screwed back in? I hope this makes sense... When I mounted the box back onto the side of the TB, you can move it up and down, or twist it really... Does it have to be set to a certain position? I tried to just use the indentions from the screws and put it back like it was...

The twisting in the box is how you would adjust the TPS signal/voltage to the ecu. You would use lets say an SAFC if you had one, go to sensor mode, and you would see the voltage change as you twist the black box. Now the Stock ECU likes to see a certain voltage range to avoid throwing codes/engine light. But with the AEM, like you said, you pretty much install the Q45 TB, connect it, then tell the AEM what the voltage range is from Idle (meaning the pedal is NOT pressed) to full throttle (pedal floored) I'm not sure if the AEM's wizard has the Q45 TB as an option.

 

Rising for the dead this topic....
I need to know what kind of IAC valve or bypass valve I need to use in order to control air on idle.
The main issue is when I turn the steering wheel from side to side.
I have 1350-1400 RPM idle in order to keep alive the motor!
I do not use an IAC valve right now and I am searching for something to use for bypassing air throygh the TB.
I have a Motec M800 ECU and q45 TB.

 

I'd be curious to find out about this too....

 

any updates on this for an evo?

 

Any updates on this for an EVO or DSM??????
