E-force install on LS2, need help with tmap wiring
I just finished the install on my E-force Ls2 and have 300 degree IAT. Does anyone have a wiring diagram for this kit? Mine did not come with one.
I do not know what pin is desinated for the IAT. It must be swapped with another pin in the wiring harness that came with the kit.
Can anyone help me out?

My install was just finished and it was found that there is some defective wiring harnesses with some LS2 kits. There are 2 pins that have to be swapped on one connection. It is the connection at the right rear of the manifold with 4 pins. I don't remember exactly which 2 have to be switched but edelbrock suppost is aware of the problem. You should call to see if that's your problem.

tried calling them yesterday but they are closed on the weekend. I am trying to get this figured out today.
but you are right the tmap is located on the right side in the back of the unit.
It seems they have been changing tmaps alot. that must be the problem with the wiring, the pins are in different locations on each tmap.

I wish I remembered for sure but I don't. Possibly 2 and 4 that have to be switched. They are numbered on the connector. There is a tmap sensor change but they just started shipping so I doubt you could have the new one.

My sensor has the numbers ground off it. makes it hard to find any specs on it. but thanks for your input.

Doesn't the PDF on the e-force site for installation help some how? Is this something that needs to be done on any new LS2 install?

Didn't use the edelbrock tune. Don't forget I'm just suggesting you may have the same wiring issue I had. It also may be something totally different. The wiring issue did cause a strange iat reading though.

yes I loaded the box tune from edelbrock and did the latest update. I belive that the pin location is wrong for the tan wire (IAT).
can anyone tell me what the sensor they have looks like or says on it and the color order of the wires coming from it?

I spoke with Edelbrock tech support monday morning about the tmap issues I was having, the software calibration was wrong. Now I have that fixed but I am still having a low idle/stall issue when I come to a stop.
Everytime I call edelbrock now The system says " we are experiencing a high call volume please call back later." then hangs up. I have been calling since monday and still cannot get through. Very poor customer service.
Has anyone had this issue?
