MP3, MSP and P5 Engine Management solution

[perfworks]

Nick, This does look promising. CorkSport is done with their HalTech unit now. I had my RX-7 guru look over the specs, and he was genuinely impressed with it. He wasn't keen on the price, as most of us probably weren't. So if this has the same results, for less money, I am all about it. I just hope they release pricing before we all lose interest (or money).
Let us know...Nic (no k)

Please dont take this the wrong way but I really didn't understand your post.
Are you refering to the corksport unit or ours when you talk about price? I will be more than happy to cover anything not yet mentioned or missed.

Damn that is good news for 3rd gen guys. I hate mazda for given us this bad damn open loop wide open throttle crap argghhhh...

I hope it doesn't cost more than a haltech or similar Stand alone, but then it has the advantage of being plug and play.

Actually this unit will work well for your car also. We already have a couple coming to Andys shop for installs and R&D in the comming weeks.

What's the new's??? I'm tired of going to this page and not seeing something I've already seen.

 

[hukster00]

he did say he will have more info after he will dyno it and finishes up the r&d in march, gess all its left is just wait and we will see

What would you like to know?

He's back!!!
Is there a advantage to getting a J&S safeguard in conjunction with a AEM parallel? or is the aem goind to take care of everything? if so then it's probably useless for me now.
Also about the boost solenoid, can i use my profec solenoid? or does it have to be one for the AEM.
Thanks,
Vik.

LOL
Just working alot bud.
Read my "lips" YOU DO NOT NEED ANYTHING ELSE IN CONJUNCTION WITH THE AEM.
It has its own active knock retard system. It will do one or two or three things.
Under specified amplified knock it can and will add fuel, retard timing, or both. It will retard timing or add fuel based on a percentage of throttle, boost and rpm. It will be preprogrammed to LISTEN for knock. Not like the stock ECU that just waits for "knocklike" symptoms and just adjusts minimally with timing retard.
We will keep the ignition system in check with the AEM

AS far as your solenoid is concerned I dont beleve we will have any problem using it in conjunction. We would just need to get some specifics on the unit and have the duty cycle mapped for you.

Very cool!

Will the AEM be able to deal with timing on each cylinder (individually) like the J&S? Obviously if you combat knock with timing and fuel, then you have the advantage over the J&S, but there is something to be said for having a "standalone safety net" that the J&S provides. IMHO

hey Perfworks,

Thanks for getting back to me. Most of the questions i asked you the other day don't apply anymore since i traded in my P5 for an MSP. I'd like to know how far an MSP (stock turbo/intercooler) can be pushed using your EMS ? I'm planning on upgrading internals and whatever else that will be needed to reach at least 250whp (hoping to eventually reach 300). I know the stock intercooler has to be upgraded, but what about the turbo ?

thank you for your time

Hi Nick, not sure if anybody asked this question but with this EMS or any sysytem for that matter make the car more reliable. I guess what I am asking is can I add to the cars life. Seems with all the things that it can control it makes sense that you should be able to boost safely and more often. without hurting the car under resonable levels. Am I wrong? Just want to protect the investment

Thanks Vinny

This really doesn't have anything to do with Perfworks' ECU, but I'll answer it for you. The stock MSP turbo is good for about 16psi....after that the air is just hot and useless. I've seen some people runing 15psi daily on there car with crap fuel management. It is pushing it, but people are doing it. With Perfs' system you will have much better control of air/fuel mixture, timing/retardation, etc.....this will be MUCH safer than running the stock ECU with some kind of FMU on it. However, the ECU does nothing to strengthen your internals (i.e. rods, pistons). If you purchase his unit and crank it up you will most likely lose the motor from the pistons giving out before the fuel hiccups and causes detonation. Your best bet is to do it right from the start. Buy forged rods and pistons. Have them put in. Buy the ECU and after all of that is THEN crank that mother way up!! enjoy your 300whp!

wait...

remember the FMIC, the stock IC is not efficient enough for over stock psi.

Dude, I was just about to say that! I am glad you brought it up. Please, ppl...do not try to boost over 9-10 psi without increasing fuel pressure. Even if you just do the FMIC, you are increasing the amount of air and cooling effeciency, but you still don't have enough fuel. I was talking to my Mazda RX-7 TT guru at work. I work with a bunch of tuning geniuses, you have to remember. They were telling me to attack the problem. When I blew my engine, I melted a piston. However, it wasn't just because of the dinky, inefficient IC. I ran lean and blew my #4 piston and fried that cylinder. That means I didn't have enough fuel pressure. So if you are increasing boost with an ECU or FMIC, make sure you increase fuel pressure also. I am trying to find an RX-7 fuel pump, and then I am going to do a piggyback ECU. I will either get one like this, or I have a sweet discount on the Greddy being offered to me right now. I can get my hands on the Greddy and all of the harnesses for less than just the main unit retails for! I just have to find out if e-Manage will work on our cars, and who can tune it properly.
Lemme know how everyone's computer management works out...

True also, I would never trust our stock fuel pumps...a fuel pressure drop and you are DONE

Beavis,
The AEM does not retard individual cylinders.
It can be done thru various outputs and cylinder trim tables but my opinion is that it is not needed. I prefer to retard ALL 4 cylinders rather than just one or two out of four.
The J&S is a great unit, but it is not needed when you run this system.

Good to hear and good luck with your new car.
If I were you this would be my mod list in the order of importance:

1. FMIC or equivilent bar and plate with hard pipes.
2. AEM EMS
3. Forged internals
4. ACT clutch
5. Upgraded Turbo back 2.5 inch exhaust

This should get you 250 WHP with your stock turbo and manifold reliably

Vinny,
The AEM EMS we will provide is going to provide you with complete control of your entire ignition and fuel range. Every parameter, input and output driver. Along with these parameters we will monitor knock and A/F thruout the rpm, load and throttle range. The unit will keep you within levels that are acceptable for performance and reliability. Much more reliable than the stock unit once you start to modify the vehicle. Basically because we are now able to tune the car for current and future mods thru AEM only. No need for additional software , hardware, firmware etc. It can be scaled to handle almost any situation. It can account for almost any boost level, altitude, fuel etc. I could go on and on, but what I'm trying to say is that when you have complete control over every parameter, then reliability and performance will go hand in hand.

That is exactly what i wanted to know. Thanks alot man =)

Very true. Probably the best $120 you will spend will be on a good Walbro 255.
