CA AEM Series 2 EMS

Hi everyone,

I figured I'd post here about the current project I'm trying to do. I'm currently working with FSR motorsports out in Montclair to get the series 2 EMS working on my FD. I'm doing this along with going single and a bunch of other stuff so the project is still in the works. I'll post more progress as the project gets under way. Anyone else tried using a series 2 EMS on their FDs?

Are you running the universal unit, or a modified (re-pinned) plug & play unit for another car?

I plan on using the Unit 2.

I don't think they make a series 2ems for the Rx 7.

I believe they will be using a re-pinned plug & play unit from another car and rewriting some of the software from the series one. I'll keep you guys updated once the project is underway. I'm still trying to finish doing research on what v-mount is best along with what titanium exhausts are on the market.

The conversion is pretty straight forward. Any good AEM tuner should be able to do the conversion. I'm hoping someone will come to Tri-Point to have a conversion done.

Is Tri-Point looking for a test car? I'm currently getting a quote from FSR motorsports out in Montclair but they aren't rotary experts.

You don't necessarily need a rotary expert. You will need an AEM expert. AEM has its quirks and the more familiar you are with it the easier it will be to do the conversion.

We do a fair amount of series I ecus. No one has asked for a series II conversion but if anyone wants one we will be more then happy to do it. The series II has its benefits but its really nothing significant. So spending the extra money probably isn't really worth it. I would want one if I had the option. The series II editor has some cool options that makes it a lot easier to tune. Not that the series I is difficult by any means.

did you ever come up with a base map/settings for the series 2? I'm in a pickle right now because i can't seem to find an AEM EMS 1 for the rx7 and they have been discontinued. I was thinking of doing the series 2 universal version for the FD.

We have a few 30-1800's on order with AEM they just notified us yesterday that they were no longer available. We are going to start developing a solution for this issue. We have a couple of options on the table at the moment. I will post updates later in the week once we decide which route we will be taking. feel free to contact us if you have any further questions.

EB have you heard anything about their new Infinity series of ECU's?

http://forum.aempower.com/forum/index.php?topic=28808.0

Would be nice if this drove down the prices of the series 2 units.

I have. The information I have been given about the ECU does not put it in the same category as the Series I and II ECU's. It will be more of a universal ECU. AEM was unsure of how much effort they were going to put into PnP adapter harnesses.

The infinity-10 is going to be a lot more expensive then the SeriesI/II ECU's. Without a lot of PnP applications I doubt it will be a big seller right out of the gate to those other then full standalone and custom applications. Don't expect the price of Series II ECUs coming down anytime soon. The ECUs that we will be using are cheaper then the 30-1800. So once you factor in the conversion harness and engineering costs, you may be $100-$200 more then the cost of the 30-1800.

I just ordered an AEM Series 2 Universal ECU. 30-6300. When i get a decent map, I will share it with everyone. If i have time I will try and make a wiring diagram of it too.

The 30-6300 is a Mitsubishi ECU. The main difference between that ECU and other Series II's is that it has Peak and hold injector drivers.

We will be releasing a Series II PnP kit hopefully by the beginning of next year.

Would it be worth trying to get your pnp version working on a car with twins? I know, I know......just spent too much on suspension this season

The EMS4 is pretty different then a normal Series II ECU. The maps do not cross between the EMS4 and Series II, even though they use the same editor. The EMS4 has very limited I/O's. not even close to being enough to do sequential turbos, emissions or, oil metering pump. If you are not running those it wont be a problem. Are you gonna make a new harness or do a PnP?

Our version will have full sequential control, full emissions device control, and proper OMP operation.

yup, single turbo, no emissions, or OMP for me. I'm buying their mini harness and incorporate the stock harness into it.

Lots. EMS-4 only has 4 saturated Inj and 4 Coil drivers. Series II has up to 12 peak and hold and 8 coil drivers. EMS-4 has general inputs, CAM, CRANK, TPS, IAT, ECT, MAP, Lambda, plus 8 General Purpose Inputs and Outputs(GPIO). Only 4 of the GPIO's are allowed to be used for Pulse width modulated functions, CAM Control, Boost control, Idle Air Control, Tach out... all can be used for HS or LS output, Switch in, 0-5v in or EGT.

Series II ecus have the general CAM, Crank, TPS, IAC, ECT, MAP, MAF and a few more spare inputs for EGT and 0-5v signals. up to 16 general purpose outputs(12Low Side, 4 High Side), 8 definable switch inputs, it only has 2 PWM outputs. Things can be done to turn one of the injector outputs into a PWM output.

Both will work with the FC CAS and the FD trigger wheel. Both will work with whatever coil you want to use. If the coils you want to use do not have an internal igniter you will need to add one. You can run wasted leading or sequential ignition.

You cannot run the OMP with the EMS-4. I don't believe it has the DC motor control. or it just doesn't have the available features to run it. the editors work very similar, they both are able to run staged injection and trailing timing.

That really bites..

Then to me this is its largest and only drawback. 8 GPIO will work perfectly for the setup Id like to do. I'm going to this ecu mostly for multi-gear boost control and closed loop operation (coming from a microtech)
Stock FD secondary injectors are 850cc and Injector Dynamics makes saturated injectors up to 2200cc. You will gain a lot more by switching to the AEM. Better staged injection, boost target control, accel, decel, 2 step, flat foot shift, etc..etc..

AEM EMS-4 $640

Then as far as ignition...
1. 4 coils crane LX92's or AEM COP $268 ($67x4)

2. Either the AEM 4 channel ignitor for $139
or a very expensive 4 channel CDI box.
I have heard bad bad things about every 4 channel CDI box made except for the Autronic 500r or the motec equivalent.
or the 2 single channel CDI box method with something running the trailings would seem to be cost effective. Maybe using two of the AEM 4 channel ignitor box to fire the trailings.
How much power are you looking to make and what size injectors are you currently running? On an FD with Stock injectors I was able to reach 350whp. I was also using both Primary and Secondary injectors to 80% duty. The AEM has a pretty advanced staged injection functions. Most cheap standalones just switch from pri to sec. The AEM will allow you to blend the balance of Pri and Sec injector through RPM and Manifold Pressure. This allows you to utilize all of your injectors not just rely on either Pri or Sec.

AEM does make a smart coil that works really well. I would recommend those or the LS2 truck coils. that way you will not have to use an ignitor.

When you buy from eBay for really cheap and you run into problems you are not able to get the support you need from the seller. Then when you try and call AEM and they may not have all of the information needed to help you fix your issues. We sell our products for the lowest allowable advertised price from the manufacture. I will contact you through PM to pass along my information.

I can updated a little since it's been awhile. As luck would have it, FSR knows someone who owns an FD and has experience designing PCB's. They custom built a circuit board to work with a Series 2 EMS so we won't have to repin and it should just plug right up. The EMS and custom PCB will be here in a week or two. I'll update with more information when I get everything in.

Im going with an F22 (S2000) Plug n play

I'm going to reconfigure it for my FD.

I'll update with a tutorial, if my buddy will let me document the process.

Any update with this or sucessful install in general of a series 2 on an FD?
