Hi guys.

Maybe someone can help me to decide which way I should go and give me some hints/tips.

short story: I currently got my first FD3S. I also have a fc3s chassis which i've wanted to build up as a drift/circiut car with a 13B REW and EFR single turbo conversion. Therefore, I'm currently owning a P2000 ecu + iq3 dash unit.

I always really wanted an fd, so now I will put all my time and money the next 2 or 3 years into the fd. I'm now thinking about puting the p2000+iq3 into the fd or sell the haltech and get a PowerFC.

Of course it would be the best option to keep the p2000+dashunit and put it into the fd3s, BUT i definitly want to keep the twins working sequential and dont want to hack up the original wiring harness.

Is it possible to take an wiring harness extension from banzairacing, hack it up, put on some haltech connectors, integrate the relais and PWM outputs to controll the stock sequential system and make it "plug and play"?

I also want to keep the possibility to swap in the stock ECU for emission tests.

Any inputs/hint's/contacts would be very nice!

thanks for all your help

Just use a PowerFC, a lot easier and youll come out with extra money.

Wait, is this going into an FC or FD chassis?

@thewird

but the p2000+dashunit is already here
I know that the Haltech will outperform the PFC all day and all night, but i don't want to build a new harness for the FD3S
hard decision :/

@arghx

I bought the p2000+iq3 for my fc3s chassis, but I recently bought an fd3s (1 week before) which is now priority 1. (as it is my dream car since 9 years and very hard to get here in my country )

By outperform, do you mean it has extra features? Both ECU's will make the same power to the wheels at the same RPM if tuned equally.

Does the Haltech have features you need/want that the PowerFC doesn't have? Those are the questions you should be asking yourself.

The powerfc is plug and play, turn the key, your car is running. The Haltech, not so much.

Of course i mean the extra programable outputs and inputs + the iq3 dashunit! That's the reson I've bought it for my fc3s project (AI injection, electrical waterpump, transmission+diff pump+cooler etc.)

In the long way i know i will hate myself for using a limited powerFC instead of the ps2000, but if I do so I can drive the car now with bolt-ons!

But i think i will go the "hard" way, take my time and integrate the ps2000 into the fd3s.

I'm thinking about using a banzai racing extension harness, a p1000 fd3s patch loom and the stock wiring harness and wire up the additional outputs of the p2000 stepbystep to the banzai racing extension harnes to control the stock solenoids for full sequential actuation.

Do you know if I'm running into problems with this setup? I'm a little bit afraid if Mazda did some crazy wiring inside the stock harness so that it's not possible to actuate the stock solenoids each on their own.

You can do what you're saying. The 1000 patch loom will work with the 2000. Get some extra pins to populate the extra inputs and output for the 2000. Also, you'll want a schematic of the patch loom to know what is already populated. Many times, for custom installs like this, you'll want to move some stuff around from the Haltech configuration. Email Haltech directly for that. Other than that, it would be straight forward. The only thing is that not too many people have controlled the sequential twins with the Haltech ECU, so you're a bit on your own in terms of support.

Thanks for your input Ludwig. I will talk with my local Haltech dealer if he can order a p1000 patch loom and will try to do this.

I have never put this together but I have drawn up various schematics and thought through control strategies. So I can be of assistance with this.

You're going to have to make some decisions about how you want to control the sequential twins. Even a PS2000 doesn't have enough outputs to run it like stock if you are keeping idle air control and A/C. It needs 5 outputs: three for the switching valves (charge control, charge relief, turbo control) and two for boost control. There are work arounds though.

I/O 12 will add all the outputs you need.
