AEM EMS ECU

[hks.mr2turbo]

Hey guys im going to purchase an AEM EMS ECU this week but im knew with the MR2 stuff. I bought the car from someone and supposaly this has a 1993 jdm motor/trans/lsd/ecu/wireharness. My question is do i order a AEM EMS ecu for a 1993 mr2 turbo ? Is it the same thing as the JSPEC one ? Does it matter if i say 1993 or 1991 are the AEM EMS ecu's different for depending on the year ? I want to make sure before i waste 1500$ + thanks.

93 JDM is the gen 3 motor. You are out of luck with the AEM EMS, you will have to repin it.

Email RickyB about the Nemesis. It's a very attractive alternative to the AEM EMS. I'm almost positive it does support the gen 3 motor in a plug-and-play fashion (no rewiring of the car). rickybenitez@hotmail.com.

Post a pic of your engine bay and we can tell you which motor you REALLY have.

OKay cool thanks, I will go home tonight and POST a pic of my motor/engine bay so you guys can help me out. I appreciate it. Yeah i'll look into the Hydra Nemessis too.. hopefully i can get one of those... -=)

Cool thanks man. Supposaly i have a JDM motor .. how could i tell ? What about the wire harness or whatever ? If it's JDM does it matter ? Supposaly i have a JDM motor, JDM wire harness, JDM ECU, JDM trans with LSD. the LSD works i tested it lol.. but i don't know how to tell about the other parts ? THanks for your help

[Enthalpy]

You have a gen 2 JDM. It's the same as the USDM circa 1993-1995, except for the EGR. The USDM motors had EGR, and yours does not. It has that goofy airflow meter, telling us it's a gen 2.

Cool thanks for the 411.. So if i have a gen2 JDM motor that means my ECU has to me JDM and wireharness too correct ? Meaning when i order the Hydra Nemessis EMS or AEM or which ever fuel computer i'd have to order a EMS for a gen2 JDM motor/wiring harness ? Will i still get Plug and Play or whats the stats for that ? I'd Perferr Plug and Play.. Any feed back on this would be greatly appreciated it Yeah the saler told me it was off a 1993 mr2 JDM, he got the rear clip from JAPAN from some company in PA. So gen 2 motors are 93-95 correct ? Also you said the only difference is EGR that the USDM motors have EGR and the JDM do not. What is EGR ?

[Enthalpy]

Yes, definitely specify which harness you have. I'm 95% sure the pinout between the gen 2 JDM and the 93-95 USDM are the same. In that case, you would use the 1121 box (AEM EMS) or the JDM jumper config (Nemesis) when you order it.

You will get plug and play for the Nemesis. For speed-density (which you want, that AFM runs out at 250-ish rwhp), you will need to wire in a MAP and IAT sensor set to the AEM EMS.

EGR = Exhaust Gas Recirculation. It's a pollution device that reduces NOx. Japan and most of Europe have very relaxed laws concerning NOx, so Toyota didn't need an EGR for those markets. They had to put it on for the US markets to reduce NOx, as the US is more strict concerning NOx emissions.

Sounds good good.. Seems like so far from what i been readin the the Hydra Nemessis EMS is a very good EMS for a toyota mr2.. I'm like 80% sure that's what i will go with. Before i decide i want to make sure i order t he right stuff lol... How can i find out what wiring harness i have ? Is there any easy way to finding out ? hehehe.... So far the saler has not lied about anything.. He said it was a JDM harness.. ... wonder if i order the wrong part if they vendor would let me return it for the correct one... hehe...

[Weasy2k]

get in touch with rickyb at mrcontrols and im sure he will help figure the whole harness thing out!
I too agree with Enthalpy in that the Hydra is defiantly something to look into!

Email RickyB (MRControls Engineer) and ask him this question. Since he did the R&D for this platform, he would know what wiring looks like what from some pictures, I'm sure.

[hks.mr2turbo]

Yeah thanks man, i just e-mailed ricky and he replied back and yes my motor is a Gen 2 motor and the Nemessis works for both the US and JDM gen 2 model... plug and play so i'm going to go for the nemessis

[Bak@EMSPowered]

Good choice, you won't be disappointed with the Nemesis, it's a great unit.

[hks.mr2turbo]

Yeah that's what i hear. Hey does anyone know anyone or any place that knows how to install the Nemessis on a gen 2 motor JDM, I live in New Jersey, perhaps someone in the New Jersey, New York, Pennsylvania, Connecticut, Delaware, etc etc hehe... ?
