ECU Questions

I'm getting a turbo kit from himni that should give me close to 400whp, but my question is can i get the stock ecu from a s5 turbo II tuned with that turbo kit? Or should i get an aftermarket ecu, and if so what would you recommend?

For that kind of power, a standalone ECU would be ideal. There are a bunch of options: Haltech, Microtech, Megasquirt, just to name a few. Everyone will have different opinions as to which is the best. Don't forget the fuel system either.

Thanks for your help, do those ecu's that named made for rotarys? I read that if you go with megasquirt that you have to basicly build it yourself? There completed ecu's are not compatible with rotarys, thats what i read. Do you know if thats true?

if you're going to upgrade the turbo system you should spend a little time reading on your own, there are areas on this forum that have sections for all those ECUs which should give you a rough idea as to what to expect.

answering all of your questions about upgrading boost will take all day in a single thread and still miss out on a few major points.

you have been given a homework assignment.

I went with the powerFC. It is made specifically for the FD application as a plug and play, and can easily be adapted for the FC with banzai's kit. Including a basemap means that you can drive your car to your tuner for future adjustments.

Keep in mind that you must have a tuning device that the person tuning it is familiar with.

Does anyone know if PowerFC is a popular ecu for FC? Basically will it be hard to find a shop or person that can tune it?

because most of the cars they were built for are older now and they have met their quota. why make more than 3,000 units for FDs if there was only 10,000 sold? yep there's plenty of FCs out there but Apexi still didn't support the switch to use them in the FC so it started to taper off for them. at this point i figure they were right, there's enough units out there to support the FC/FD community built for the car already.

it is also a dated EMS, it lacks by today's standard compared to current technology, although it does the job it needs to do in most cases.

It is a very popular ECU for the FC, we have sold our kits all over the world. Any shop that can tune the PFC for the FD can tune it in an FC. The PFC is the ECU of choice for FD owners since it is PNP and still controls the stock twins, this means any shop familair with the FD should have PFC experience.

I would never go with a power FC. I would stick to something that isnt so dated and allows room fro growth. try looking into a haltech as they are cheap, affordable, and come out with new stuff all the time and has a huge user base. hell, all are good, but all are different. its up to you to decide.
go with one that fits your budget, and go with one you feel more comfortable with. download the software to tune them, and figure it out.

i myself chose haltech because its super easy to work on, the software is straight forward, and the things just work. stay away from the e6x series as they have trigger problems sometimes, but every other one is good. i would look into the sprint RE's. made specifically for rotary.

Speaking of Standalone ECU, I wonder if anybody tried to use FCON V-Pro 3.32 (I believe that's the newest version)

it should have no problem controlling everything, but I guess it might not make sense cuz it will be pretty expensive which I don't think most FC owners want it.

Maybe I am Biased,But I would suggest the Haltech PS1000.
The thing is easy to tune,is compact and hell!,it does a good job!
It is pretty well a new Ecu and the support from the dealers and the Haltech site is Honestly Top Notch.I went through a couple different Ecu's before I got this one.
The Main reason I switched is no Support on the Previous Ecu's.
It may be a little more that what you want to spend,but in my case,having the car NOT run right for 4 years and now it DOES run real good,it is worth it!.every penny!

I have been reading a lot about Haltech and they seem very good. But my only concern is that i have never tuned a car myself, are Haltech's that easy to learn like people say?
