View Full Version : Getting an aem, what else...


mr2slow4you03-04-2006, 07:07 PMI am about to order an aem ems for the 93+ mr2, what other sensors or add-on's would you reccomend purchasing with this? 91T_SW2003-04-2006, 07:22 PMI am about to order an aem ems for the 93+ mr2, what other sensors or add-on's would you reccomend purchasing with this?


read mrcontrols.....there's like a ton of sensors you gotta get i believe when i was looking into getting that.....


I would get the Hydra since its whats most commonlly used.. mr2slow4you03-04-2006, 07:32 PMI am goign to go with aem, because I can get a great deal on one and there are so many more professional tuners that tune them. Weasy2k03-05-2006, 11:10 PMMap sensor for laod refrence
Intake Air Temp sensor....

uhhh
shit i forgot if there was anything else...im pritty sure thats all yo9u would really need considering it uses exisiting sensors for the rest. Just that when u take off the AFM u need osme way to read the airflow and temp.

(excuse the bad spelling/writing...im in the hsop wearing gloves...) mr2slow4you03-05-2006, 11:53 PM^lol ya gloves are hard to type in. MR2TuRbZ03-06-2006, 12:05 AMyou need the AIT (Air Intake Temp) GM part, and the MAP Sensor from GM

and if you want, you can use a boost solenoid from GM to have the AEM control the boost electronically mr2slow4you03-06-2006, 09:53 AMIf I get the car professionally tuned is it still a good idea to have a wideband?
Also what about regular gauges such as oil temp. ecm garrett03-06-2006, 10:41 AMnothing wrong with having gauges to monitor your stuff jason Weasy2k03-06-2006, 10:50 AMits actually something you should have...
Make sure you got the port to plug the wideband in on the downpipe and most of the time dyno shops will have the wdieband units on site.

So yea IAT and MAP :) ecm garrett03-06-2006, 10:50 AMps - jason, when doing gauges - no pillar pods please Enthalpy03-06-2006, 11:06 AMUse the AEM MAP, not the GM one. I have seen them wonder on me. The GM IAT also has quality issues, (surprise, surprise) but it is at least usable after you test it. Measure the resistance vs. temp values of your sensor before using it.

The AEM EMS is incapable of operating in closed-loop using your narrowband. This is one of the big drawbacks of the system. If you ever want to be in closed loop, you need a wideband.

Some argue a well-mapped EMS doesn't need to operate in closed-loop. I beg to differ. This might be the case with race gas, but pump gas varies quite a bit!

You will also need this:

It puts the IAT in one of the best places possible.

Don't forget the sensor pigtails for the MAP and IAT. mr2slow4you03-06-2006, 11:28 AMps - jason, when doing gauges - no pillar pods please

You know me, I'd never get an A-piller. I hate to have any gauges, I planned on using my laptop connected to the aem to view what I can.
