Hey guys.....i was just in the rx7 store and was wondering which EMS is better.....the AEM or the Haltech system.....do anyone use any of these systems?....if so....is it as user friendly as they say or not......would like to get some info on it before shellin out that type of dough.....thanx....

Haltech is proven whereas AEM is a newcomer.

The AEM offers faster performance, plug and play with the wiring harness, onboard dataloging (ie without a laptop), integration of several systems into one CPU wich is more reliable, etc.... The downside is BOTH systems require you run a seperate boost controller and the fuel maps on the AEM aren't as mature (ie pick you map based on the mods you have).

Haltech is definitly proven, there are fuel maps & extensions to work with a 3rd set of injectors, 3 rotors, etc.. You can pretty much get 95% efficiency by download a fuel map based on your mods. (ie little tuning).

Haltech requires you to run a second wiring harness or splice into your OEM harness. Most people agree you'd want to do some of this with the AEM even though it's PNP. Basically you'd want upgraded/more efficient sensors to work with both systems (O2, air/fuel, etc..).

The Haltech requires 3 or 4 boxes to do it right if I remember correctly.

Anyway that's what my R&Ds turned up. I'll probably go with the AEM because of its features and I'm expecting ALLOT of trial & error during tuning. I'm planning on using most of the OEM fuel system with this ECU just to max out the OEM setup

 

Are they even shipping the AEM one yet?

 

I have a Haltech F9 on my lightly modded '88 Vert Turbo, and it runs pretty near as hard as my (stock) '97 FD....

If you want any info (and a great price) on Haltech visit RPM and drop Tim an email (I have no affiliation, but he looks after my cars VERY well and knows his onions!)

 

good point - late summer right ??

 

I don't think the AEM is even out yet. and it isn't plug and play for the FC. you need the race version that comes with it's own harness like the haltech. so either one you'd rip out all engine wires and ecu and replace. not an easy job. nobody has used the AEM since it's not even out yet. the Haltech is very proven and lots of surport and people who know how to use it. but get the e6k. I don't even now why you'd bother with the F9

 

One of the developers mentioned they were planning to make a FC wiring harness adapter just like the FDs.

 

The Haltech also has datalogging, and I don't know what is meant by the "systems integration" of the AEM, but to me it looks like every other EMS. Both have boost control, but the Haltech's is not very good, and the AEM's remains to be seen. No Plug & Play AEM for the FC right now, and I wouldn't hold my breath for one in the near future. Before you decide if new wiring is a downside, look under your hood again, and notice the nasty, greasy, cracked, 11-16 year old original wiring and corroded sensors that Mazda charges a fortune to replace - do you really want to use this on your baby?

My own opinion is that the AEM looks very good on paper, but the E6K has been proven to work. I haven't even seen the AEM for sale yet, so I guess that makes the choice easier.

 

How many extension boxes do you have to buy with Haltech again ??

I though Haltech required you have a laptop hooked up to get dataloging. My OEM wiring and sensors are pretty nice thank you Granted the "no shielding = weight savings" is pretty pathetic.

Its enough to make you want to go carbed/analog again

 

Define "extension boxes"...


Sure, the Haltech datalogs to "disk"; this means it'll keep datalogging until you run out of hard drive space.

Can you name another EMS which does on-board datalogging?&nbsp The only ones I can think of is MoTeC and Wolf...

Is the MoTec any good for rotarys? whats the difference between Haltec and the Motec.....good and bad....is it more user friendly....is the price comparable to the haltec

 

By the way thanx for all the info guys.....

 

Yeah the boys at Mazcare in Atlanta are all MoTec. I think it's more accurate for race cars, but runs a pretty premium.

Also I have no clue of fuel maps.

 

Motec is the top of the line EMS for rotaries, and is used by Downing Atlanta, among other pro race teams. It is NOT user friendly, but there are factory-sponsored seminars for "young engineers". LOL, the Motec M-800 is only about $6,500 more than a Haltech E6K - chump change.

hehe ;o)
we got Haltech E6K from Tim recently and installed it in MaTeZZ's car ;o)

Cool pics bro......was that much of a pain in the *** as the pics shows.......but hey.....in the end im sure its worth it.......

 

it was breeze, pain in the *** was going to work in the morning after working on car all day long and most of the night ;o)))

 

hIGGI
I got my in from Tim this week
What is the Orange plug for???????????

 

MoTeC will work on a 2-rotor no problem.
The MoTeC programming is a little bit more hard to decipher initially, but once you get used to the controls it's not too bad.
Minimum, a MoTeC M4 Pro will cost at least $2000 - almost twice as much as a Haltech E6K.&nbsp The MoTeC hardware is top-notch; all connections and wires are Mil-Spec.

if i`m not wrong (its not mine car and i`m not standing next to it right now) i think orange plug goes to Haltech 3BAR MAP sensor....
