I want a fast RX7 my dream is 400hp and I know I'll never even come close with the stock ECU. I've started with some cheep mods (cat back, intake, radaiator) and already I am dealing with 14psi boost spikes and other annoying things that can lead to big engine cost. I have never owned a programable ECU before. I have alot of mechanical know how and I need a serious EMS, the Power FC just won't cut it and I think you serious tuners know what I mean. I hear that maping an ECU can be very tricky and with a $1000+ price I wan to be sure about what I should get AEM and Halteck are the biggest, most popular names I hear for an EMS. I want hear from people who have tried one or both of these ECU systems and tell me what you think about :

installation
first time start was the base map good
tuning - hard or simple
how is works with single V.S. sequen. turbo
tech help - is it out there
the provided instuctions - were they usefull
does it take long to learn how to tune it

any other coments/concerns a new person to EM should know or think about

Thanks

 

Well i have never used an AEM on RX-7's but i do have experience with them on honda's... Everyone of them has gone bad. Most times more then one occasion too.. I would highly recommend you say away from them.

 

Interesting !

I remember the "poof" from AEM giving Autronic ****, I told him when AEM have a proven track record I will consider his "perfect" ECU. He never got back to me on the Autronic unit he wanted to literaly give away.

Either way, we have not herd much from AEM latley ? Are there many on rotaries yet?

PS Nice to talk to you today Enzo

 

Well there is some posative feedback in the AEM forum but not much. So is the Haltech the way to go? will a hatech come with RX-7 wire harnests?

 

I think you need to do more research.

Seriously? Why do you think it won't cut it? I'd bet that a lot of the "serious tuners" here WON'T know what you mean.

 

The Power FC doesn't have nearly as many functions and it's only like $200 less. It's a good option for someone who doesn't have a laptop.

 

Sounds like you haven't looked into the Datalogit, which lets you gain access with windows to all the functions for the Power FC, and for me I'm very much so in limbaugh, since Power FC with Datalogit = AEM price wise... then you add the commander and the Power FC is more, but now you can monitor things like radiator temp etc... from the little hand held thing, and don't have to open a laptop...

Choices Choices...

 

How bout a plug in microtech?? install takes about 15min, will start and run like standard on the base maps, can run twins and single turbo easly, control your OMP,

 

is the microtech stand-alone? if not then isn't limitted by the stock ECU?

 

The Plug and Play is stand alone, unplug your factory computer and plug in the microtech. it fits in the factory position behind the kick panel where the factory computer sat.

i was very interested in the microtech until i found out that you cant do any wideband datalogging which is one of the most important features of any ems.

 

Wide band logging is in the works, they are working on it now, they will log narrow band now,

Dont think the E6K will log wide band either, as you can use the same oxy sensor on the microtech and the E6K.

 

Is there any support out there for microtech? Have they going to be around for a while?

 

I have been using the EMS for months on my Honda with great success. I say it is one of the best systems on the market for street driven cars. In cases where people mess their cars up running a standalone system, 99% of the time it isn't going to be the fault of the computer, if you know what I mean. The AEM EMS is an incredibly capable system, and basic tuning such as fuel is much easier now with automapping. Rotories are pretty touchy when it comes to tuning - I've always seen people have great luck with the Power FC, but the in the hands of a capable tuner the EMS would be a step above for sure. I've tuned the ems on Civics and Supras so far, and combined with a wideband o2, it is incredible.

Microtech have been in Australia for around 10 years now, 90% of the mazda rotors in aus have them fitted, most people doing engine conversion will use a microtech, they are a lot cheaper than all the other computers and easy enough to tune so that most people can do it them selves.

all bar one rotor workshop that i can think of off the top of my head use microtech as there number one computer.

Dale

 

Thanx 10sec RX7 I'll look into it. Do you have a microtech in your car?

 

Yes i have a MTX8 in my car, im getting it upraded to the LTX8 specs in a few weeks,
may car used to be a daily driver before i pulled it off the road to rebuild the car.

 

So why is Haltech to highly recomended by a tuner I know here in Boston? I think it's the most expensive which is bad for me cuz of my limmited buget. Microtech sounds like another good option. I want somthing that can hook up to my laptop

 

Microtech are basically unknown in the USA, they are just starting to get the dealer base set and the products into the USA, they have been at the top of rotary drag racing in AUS for 10years,
Most shops will have there perfered ecu and they will try to sell it no matter what

 

I'll stick with my AEM! 500hp to the wheels, and counting! In just a few pulls on the dyno as well. It is so simple it is crazy!

 

When AEM have 1300hp motors running on there systems and not blowing to pieces ill look at one

 

Well seems like the pos. feedback is for the Power FC and Microtech. And everyone is mixed about the AEM havent heard much from the Haltech users yet but I guess that just shows that most people don't use them. Haltech is popular in Drag-racing so I thought that ment it must be good. But maybe that just shows it's not so great for the street.

**** just keep giving me feedback on your experiences with the different EMS's

 

So you have a 1300hp RX7 that runs 10's? WOW that's impressive.

BTW, there already are several Supras making that kind of power.

 

no one cares about Supra's, they cost too much
