What do you think the best ems system would be for my 88 rx7?
i have been considering haltech i think i would possibly go with the haltech E8

please give me some suggestions thx

 

That Is a subjective question. You will more than likely be able to get alot of Info searching on this topic In the Engine Management Forum.

 

haltech is a great system. i run an apexi power fc in my FD but i dont think they make them for the second gen's. if they do i'd get the power fc. otherwise haltech. dont get a piggyback system. waste of money.

 

yah thanks alot

 

The best ECU is the one that your tuner is familiar with.

 

How about Weber or Holley?

 

They don't......however Tofuball (??not sure, but one of those EMS guru's) makes a retrofit to work in an S5.

 

power fc was sold for second gen's in JDM land i believe. not too hard to make an adapter anyways if you are somewhat knowledgable with wiring, etc.
engine management forum like silverrotor said...your answer is dependent on application, your own knowledge, etc.
i have a MegaSquirt that will be going into my car...

 

Not quite an ECU....

 

this is my ECU
*points at foot*

haha...

 

They do make them for the 2nd gen, however it's modified via a tuner house in Japan... AP Engineering. I have access to one rght now for the S5 TII, comes with the commander and loom adaptor for $1600, new.. so yes they are out there.. I've just never seen one for the S4 TII.

haltech or microtech seem to be the two big choices for ontario FC owners from what Iv'e seen.. however the megasquirt 3 system seems to be a very affordable and viable choice.. allot of the developers for this system are based IN Canada or have close connections with the MS rotary code designers.

 

Best ECU?

MOTEC.


Why?

Because you can't afford one.

Im making my first choice a microtech should I ever buy a ECU. To me, they seem more functional for me.

 

umm.. some time ago i was talkign about this subjest to a couple buddies and they send there are adapter harnesses that fit between S4/S5 or S6. so u buy the power FC and the S6 adapter, then it works. we never quite figured out what happens with the extra sensors, like the fuel temp?!?!?!

 

First thing it'll really depend on is what you can afford. Any Standalone ECU will run your car so long as it can be setup for a 2 rotor (assuming you still have a 2 rotor).

My first choice (w/o much research) would have been the Wolf 3d V4 for engine reasons. However budget thinking and the fact that other friends were running it pretty soon led me to buy a Haltech E6X. Wich is more then you would need for a street application RX-7.

You can tune the car (with enough time/money) to run much better then it ever did with the stock ECU and with alot more power then in stock trim. (not that i would know from my own car unfortunatly)

 

I'd think the best would be Megasquirt. It's customisable, cheap and effective. The low price means that you'll have more $$ left over for other mods, making the car faster in the end.

 

The PFC is great for an FD where you can PnP and probably want to keep all the stock sensors and systems. But, the dataloggit with FC Edit software sucks the big bone. Tuning with FC Edit is time consuming too.

Wolf3D does offer PnP units for S5 FC and FD as well.

But for us FC owners, forget the PFC. Since we generally remove most of the un-needed stock sytems and wiring, and like to strip the car out, I would run one of the other EMS, mainly to get rid of the old/messy stock wiring harnesses and have one, simple, new harness with only a few sensors. Like with the Haltech, for example.

For ease of tuning, the systems I have played with: Haltech > FC Edit PFC > Wolf3D with Handcontroller.

Best EMS is Magneti Marrelli

 

Wow thanks guys
but you all gave me alot of replies but im still in the same position
you all gave me ideas but no reason why one isbetter than the other im not spending over 1500 i thinkn i ll just go with haltech e6x or e8

 

Better/best is relative. All EMS do the same thing (control fuel and spark), and have similar base features. Sure, when the price goes up, you get a little more, like extra resolution, extra inputs/outputs, more compensation maps and other features you may or may not need.

When I replaced my Wolf3d with a Haltech E6X, I did so for two main reasons.

1) The software. Haltech's bar system makes it very easy to set up the map and simple to tune. Some guys prefer a big number grid like the PFC, or the Wolf. I don't, because the bar system gives you a graphical display of your curve as well, not just some numbers.

I spent quite a bit of time playing with all the software I could find to see what I liked best.

2) Ease of install and compatibility with stock systems. What bothered me about the Wolf3d V4, was that you couldn't use the stock T2 trailing coil anymore, because the EMS was not designed to incorporate the trail switching. That was totally lame, since my old V3 Wolf could do it just fine!

I am not up on Microtech as much, but when I was shopping, each ECU came pre-coded for your specific setup. And if you made drastic changes to your car, it would have to be sent back to the factory for reflashing. Plus, you couldn't really save and share maps. This may have changed by now, but I don't know.

You need to decide where you are heading with your car. For your usual 2-rotor, big turbo with FMIC FC, ANY of the decently priced EMS will run your car really well, and if tuned right better than stock.

 

thanks ill probably go with the haltech
ive already looked up allot of info on it.
all the other programs seem confusing

 

Haltech appears to be the more common ECU in use from my observation. That means lots of tech support.

 

it'll just point out that the speed machine FC for the pinks race, used a haltech e11v2

 

And the car was also "Built from spare parts".

 

apperently the haltech has a few fail safe that help u not blow ur motor by tuning on the fly, but full features while on a dyno. such as min/max timing control, sensor priority. haltech is also PnP, with the flyinglead handcontroller

 

My 2 cents...

Having experience with all the ECUs mentioned here (besides the PFC and Motec) I can say this:

Megasquirt: This is a great ECU if you can DIY it and have some electronics skills. The MS 2.2 board has virtually no protection if you screw up and it WILL fry. Also you need to build a small circuit to interface with the FCs CAS. If you use the MS 3.0, it is a much better design with proper protection on the flyback (injector driver) circuit. Also doesn't need more then a few simple mods to run the FC ignition. The MS software can be a little hard to understand at times but it is very well designed. Either version of the 'Squirt is PACKED with features that you can't get until you start spending more then $1500 on an ECU. But keep in mind that until you have everything running you might be cursing the decision.

Haltech: The most common, which in a sense is a good thing because there are about 5 million base maps around so it's likely that there is a map close enough to your setup to allow you to drive the car immediately after install. Of course it will still need to be tuned before you go into boost...The wiring harness can be a little intimidating for the new user and triggering problems are common with the E6 series and the stock FC ignition. Lots of features, 99% of which you will never use. The software is pretty good but the keystrokes can be confusing if you are not used to the DOS software. Lots of support in the Haltech community as well.

Microtech: My favourite. Does 90% of what the Haltech does for a little less money. Simple and clean wiring harness, but the software is not the greatest as it is designed to mimic the hand controller. The hand controller is a great for on the road adjustments but is not a good primary tuning device. The unit come with a base map for your car with means that it's likely going to work first try, and I've never had any triggering problems in any of the Microtech installs I have done. If you want to add options like the BAC valve or swap it to another car (like one with pistons...) then the unit has to go to the manufacturer for software changes. Also, it can be hard to get ahold of options and accessories. Might be a problem if this is a daily driver.

Wolf3D: Aweful. Doesn't run stock FC ignition, load of triggering problems, the most unintuitive software I have ever seen, support is basically done by one person and did I mention the software makes me want to cut myself? On the plus side it has a very nice wiring harness, lots of status LEDs on the unit and does have a hand controller....Also expensive.

 

I've only seen and heard of one Wolf 3D around here. Im neutral in my opinion of it however, since I havent heard anything either way.



Didn't that 400+ HP FD in RXTuner have a wolf 3d? Been awhile since I read that issue, but didnt they have to call in some uber specialist to tune the thing?
