As the title says, I am wondering if anyone knows which EMS control the stock oil metering pump an s5. As it sits, I have been searching here and so far I believe the WOLF 3D line control the stock OMP correct? I basically want to see what my options are as far as an EMS and most of the threads are outdated by a few years.

I also saw AEM supports it, but from what I read is that their customer support isn't the best and I wouldn't want to spend 2K on it if this is the case. Any other brands out there that can do this?

I was thinking of using a megasquirt since I have experience with it, but read that it would be a pain to control the OMP. On the side, I have also found that you can leave your stock PCM and give it TPS feedback along with other sensors and it would still control your OMP if using megasquirt, can anyone confirm this? If so has anyone here ran this type of set up?

Thanks again.

You could use the Apex'i Power FC. Banzai-Racing offers an adapter harness making wiring mostly plug and play. I also thought I read a thread about modding the S5 throttle body to install the linkage rod for an S4 MOP. Then you can run an S4 front cover w/ the mechanical MOP.

once you go standalone, take the omp off, use a block off plate and premix.

The power FC, from what I looked at I would have to go with the universal one or is this the one where I get the FD version and use the harness to convert it to the FC?

I also do not want to install an s4 OMP. Any other EMS that have this feature?

I thought aout this, the only thing that worries me is if one day I forget to premix, thats what worries me.

On that note, what did you do about the oil injector holes? did you remove the pump and all the associated hoses and left the injectors in there?

There is no such thing as a universal Power FC, they are all vehicle specific. You can either install an old AP engineering unit (whihc is a modified FD, with a harness) or and FD unit with our harness. http://www.banzai-racing.com/product...ss_adapter.htm

The AEM also requires our harness adapter kit to install the FD version in an FC.

I have been looking through alot of EMS lately so I can't remember every detail from specific ones, I must of been thinking of the AEM universal EMS. I will check out that kit, thanks for the link.

one day of forgetting premix will not do any harm, I dont run premix instead I chose a elaborate adaptor that the airplane guys are using, problem is the airplane guys are almost always at the same RPM range, so I needed a adaptor to make my adaptor work with stock s4 linkage, even though my motor is bastard of S4 front cover, s5 housings and other parts, FD rotors and rotating assembly, etc..

why are you so set on a power fc? its going to be more expensive and less functional than a microtech or haltech. it also uses your 20 year old wiring.

having used the PFC and other EMS's, it has its advantages and disadvantages like everything else. the biggest disadvantage of the PFC is its limited/non-existant closed loop control and no real switched outputs (besides and electric fan and a crude EBC). this does annoy me sometimes but it's nothing I can't put up with. I also wish it had multiple IAT correction tables based on load, and better control of BAC valve duty cycle.

the advantages are ease of installation, nearly flawless injector staging based on duty cycle (not rpm or boost), OMP support, and the use of the OEM harness. In my opinion OEM harnesses are far better than aftermarket harnesses just because everything is cut to length, the connectors are high quality, and they are shielded from electrical noise very well. But a good condition aftermarket harness beats a crispy factory harness any day. Most FD owners just buy brand new OEM harnesses, but they also have deeper pockets than many of us here.

The fact that there is 3x as much tuning (and self-tuning) support for the PFC on a rotary than anything else means that it is the easiest for the DIY person. The PFC also has far less sensitivity to electrical noise and grounding. I am using a 22 year old harness on my PFC with no problems, and I made 386rwhp. I can post logs of how smooth the sensor signals come in. How often do you hear about noisy tach signals on the PFC (as opposed to Haltech especially)? I had loads of tach signal noise on my old Megasquirt.

but you're right, the Power FC isn't going to be cheap. with the adapter kit and a used datalogit and PFC box, it's still going to be over $1000. to the OP, I have written a decision/tuning guide for the Power FC on the FC3S: http://www.geocities.com/arghx/PowerFC.FC3S.Tuning.doc

Haltech has well documented noise issues that cause tons of problems in the high rpms and the Microtech has crappy resolution, NO customer support, NO ability to save maps and both of them require that you rewire the entire engine and ignition system.

AEM universal is twice the price of the FD PNP. It is also not configured to run a rotary and does not come with a harness which is $700-ish extra, it is really not a good option.

The AEM FD EMS can be used and has loads of configureable outputs including additional injectors .It also has multiple EGT and 2 Knock inputs as well as an auto-tune function. It really is a very capable EMS with nearly unlimited tuning options.

Arghx- you might want to look into the AEM, you are all set up to install it since you have our adapters already. It has everything and does everything that you listed that you think you are missing with the PFC.

Compared to other EMS, is the AEM FD EMS capable of using all of the factory sensors on the s4/s5's. I have seen some other EMS's where they require you to use certain "gm" sensors for a few things. I am mostly concerned about the ignition coils though as I have seen that on other systems you must change them out.

Thanks.

Haltech E8/E11 and newer models controls toe eomp as well.

Depending on the EMS you want, you know that you can get a stand alone controller for the eomp, therefore you can run any EMS you want.

I didn't know this, anywhere I can find more information on this eomp controller?

I hear what you are saying, but I will never own an AEM product again. Their techs fucked me over bad on warranty claims for their POS wideband, and basically treated me like ****. After a month of being dicked around, including a product return that resulted in no repairs, I finally had AEM customer service intervene. I hate the AEM EMS software too. It has way too many useless menus, and their datalog viewer is inferior to FC-Edit.

In a perfect world I could somehow have Hondata on my car (their high end S300 model). That is by far the best EMS I have ever used. It is a chipped factory ECU (daughterboard) with most of the functionality of the AEM EMS, the reliability of OEM Honda hardware, the support of an English-speaking staff, and a logical and user-friendly arrangement within the software. The best part is, it's still cheaper than a PFC. Obviously it's only for Hondas though.

Both the AEM and PFC use stock sensors and OEM coils , but the trailing igniter needs to be modified

http://www.banzai-racing.com/FC_coil_install_how-to.htm

Both need the FD IAT and a map sensor for use in an FC which we include in our installation kit.

Thanks for all the replies, I am going to go with the AEM for my upcoming project. I know a friend who uses one and I liked the interface, plus it seems to support everything I need it to.

I'll get that harness from bonzai in the near future, thanks for your help.
