hey..im not trying to start a war, but im very indecisive as to which system to choose for my FC3s. I know both systems are very excellent, but i would just like some outside opinions as to what people would suggest. I like the ability to redo the entire engine harness as with the microtech, but i also like the plug and play capability of the power fc. Anyone just give me some views as to advantages.. thank you....

 

Sorry I can't be of any help, but I am curious as to if anyone has used a Power FC on a TII, if so I doubt it is very common..

Its seems to be the choice for the FD so why not the FC?

 

Heres my point of view i have a 1990 rx7 turbo

Im in the same situation only diffrence i dont have support for any ems around here.therefore i would get the power fc d-jetro(map sensor conversion) only other thing needed is the fd or apexi iat.I finally decided i will get the pfc for my fc3s..I decided between haltech e6k/e11 and the microtech.You can still hookup the datalogit to the fc3s.I dont want haltech because takes long to install but is a really good ems and lots of support. these days the power fc maps are growing.As for the microtech,easy to install but i like the display=commander of the power fc instead.Also i can keep my emissions for my car if we ever get emission laws of some kind.i dont have any good or bad things to say of microtech,but these are some reasons for me wanting the powerfc,its about 211000 yen.then have to get datalogit for another $300 for the pfc datalogit and i want it cuz its original and looks really nice.

 

Dynamite,

you like the PFC commander, the microtech has a hand controller that does everything, you dont require a laptop to tune it,

well..thank you..Im actually looking for info as to the clarity in tuning of each unit. Do either of the two units have more resoloution in certain areas that the others dont. Its easy to read about it from the company but usually you get better advice from experience.

 

i have never tuned a power fc so i dont know,
i do know that the power fc dont have air temp corrections and stuff, where as the microtech has both fuel and ignition corrections for air temp.

Ok im not gonna try to compare which is better but im gonna ask which is better for a beginner??sorry for jacking your thread but would the power fc be a better ecu for a beginner, especially if its NA?? since i've been told its plug and play

 

Umm where do you plan on buying a Power FC for an FC? Last I heard there were about 3 in the whole U.S.

 

So where is the 86-92 RX-7 plug & play Power FC on the application list again? I'm having trouble finding it in my old age. Maybe one of you youngin's can help me find it.

hahah ok i guess theres none, i guess i was told wrong

 

Well I guess that pretty much solves the P-FC vs. Microtech dilemma as far as the FC is concerned.

 

Actually there is a Power FC for sale in Japan for the S5, or was, kind of old now i guess, but it was never for sale outside Japan. There is 2-3 cars on the forum that runs ieith t though, but it is NOT bolt-on and i think you have to be pretty good when it comes to electronic to make it fit on an US ECU. So basically, it CAN be done, but go Microtech instead, easier and probaly cheaper in the end. Search and you will find some topics, it was up about a year ago.

 

here you go..

0nce youve gotten this you need the fd intake and the apexi 3 bar map sensor..

power fc for the fc3s, ebay

 

LOL, $1,200 starting bid, and then you need to rig your car to use it?

 

sorry about the mistype there.. ok once youve bought the power fc and commander for the fc3s, you need the apexi 3 bar map sensor and the fd or apexi intake air intake temp sensor,then you need the datalogit for full control, so thats about 17-1800usd right there thats if you buy the ebay. usually the whole power fc commander setup for the fc3s brand new is 210000 yen from border racing, or from ap engineering who actually make the product then again another 300-400 for the datalogit..

microtechs base maps are fairly good but still need fine tuning like any other ems, microtech does have the handheld controller and is easy installation. only thing i can see is it doesnt have is closed loop.the lt12 lets you datalog a wb 02 on it.

 

The Wolf3D V4 and Haltech E11 are both less than that, and they have digital boost control and far better fuel injector and ignition resolution. I don't see much use for running in closed loop, but they have that too.

 

thanks for the heads up, quick question for you, did e11 get all the bugs outta there system, im actually in the process of finding a ems for myself..

Thanks

 

I don't know, check in the Haltech forum.

I wish I could tell you that all of the big EMS manufacturers give me free products to test and evaluate, or that I am a multi-millionaire who buys every EMS ever made so I can give a full report to you guys, but alas, that is not the case.

 

well actually i have a friend in japan who can get me the AP engineering version of the power fc which comes with the pressure sensor for 1000. The fd intake sensor is not necessary, it is also not too hard to find. My main point though is which system offers more flexibility and fine tuning. I know what is involved in each setups price. I mean i know microtech doesnt cost that much compared to other systems so thats why i am alittle skeptical as to whether it is reliable for a rotary engine in the long run. I am totally against Haltech only for the simple fact that i have seen too many RX7s pop their motors using them..Also i understand that haltech has lots of ignition scatter at high RPMs

 

Please define flexibility and fine tuning. I have a feeling the two products in question would end up at the bottom of the list in these categories.

Microtech EMS products have proven reliable on RX-7's for many years. The low price is mostly due to its limited features.

In that case, it sounds to me like you should keep the car stock and not work on it yourself without professional supervision.

Agreed..Im going to do my own tuning, first because ive been reading up on it for several months,almost a year now and im enrolled for the automotive tech program at the college which will give me more info on the principles of things like pre ignition, detonation and such..microtech,haltech and power fc are all worthless if you dont know how to tune,these ems are the most commonly used on rx7's,no matter what ems you get,tuning is the heart..go learn how a carburaor works, such as the accelator pump circuit, the power enrichment circuit,because thats where it all started from.the principles havent changed from carb to fi.

I am the winner of that auction. I ordered a Microtech LT12 but Microtech is gay when they take 6 damn months and cant deliver a product so I decided to get my damn money back. I dont care how good Microtech is but if they cant send out a product within half a year without sending screwed up versions of it 3 times back and forth, then how can I really know how good the unit is if it never freaking gets here? Power FC all the way.

 

Good stuff my friend, i was actually thinking about buying that one.nehow if you ever get a big turbo make sure you get the datalogit and the apexi 3 bar map sensor.go slow and learn the tuning..im still at a coin toss myself with a ems..

Good luck..

 

Who did you order the unit through??

you will probably find the dealer screwed the order....

 

The unit was primarily ordered through a good friend of mine that goes by BigWoogie on the forums. But he goes through BR7 and it wasnt the dealers fault(bigwoogie). We constantly got emails from Tim in australia saying that "this time it will be correct". BS. They sent my unit out three damn times and every damn time the unit didnt have the wideband function built into the LT12. So we kept sending it back and it got really old really fast.
