Power FC into S4 TII?
I'm currently looking at a 1988 Turbo II, seems to be in good shape, rebuilt streetported motor with 3mm seals, etc. It has a T04 turbo and manifold but an almost stock fuel system (FD fuel pump) so it hasn't been boosted in quite some time.
The only standalone EMS i have any experiance at all with on rotaries is the Power FC with a 1994 FD. I really like the system with the FC Commander and all, and am just wondering if a Power FC is available /or can be modded to work with the S4 TII.
Thanks for your help

Not available for S4's. It's not really even available for S5's, but some places fit FD ECU's into S5's because they're very similar, and can then have the PFC fitted. The S4 ECU is quite different.

Well, is it possible to get the FD Power FC to work with an S4? Any sites that I can look at to get info? I have searched quite a bit on both rx7club and nopistons...

Is the Power FC not a standalone? Why would you need the stock ecu from the FD fitted into a S5 when the Power FC replaces the ecu as a whole?
I was doing some reading and it goes something like, "AP Engineering modifies the the FD power fc to work with the FC3S... and they actually have FC3S something something for the serial number on the power fc..." and something about modifying something to fit with the FC3S manifold... but apparently these units are very hard to find especially in north america.

It's just that there's no one that has done it and offer this "modded" Power FC to the general public for sale (that I know of).
By the time you get all of that taken care, I think a Haltech (or almost any other stand-alone) ECU is a better bargain for the money.

This thread so belongs in the EMS section btw... Also you might want to do a search in that section with keywords "power fc fc3s" or something... I did this search a day or two ago and that's were I got the "AP Engineering" modded version info.

Ted's right, given the work required to get a PFC working on an S4, you might as well buy a Haltech. At least you know it'll work right.

Meh, my reasoning for wanting the power FC is that I KNOW how to tune it and can do so with a wideband +butt dyno, at least for a good idea of power and most importantly correct A:F ratio tuning, and then rent a dyno for an hour or two and tune for power, but I don't have a laptop (hence the want for a FC Commander), neither do I know how to tune a Haltech.. anyways, thanks for the help, i'll prob end up going with the Haltech or an Electromotive TEC III with coil-on-plug ignition.

ap eng. only has it for an s5. not dissing on the pfc for the second gen (cause i have one), but like RETed said....ud prob be better off getting a haltech instead of trying to get the pfc to work for the s4. there is more to the pfc than just a harness to make it work. ap eng. rechips it to make some differences between the fd and s5 fc work, even though i forget what some of the little things were. im sure someone could easily figure out the harnessing part to make the pfc work with a s4 but the chipping is the main thing. there are even more differences between the fd and s4 fc that would have to be worked with.

AP engineering makes a PFC for the S5. It's a modified FD one and you will need to use several stock FD sensors (air intake temp and MAP or GM map sensor or 3 bar apexi). You'll either have to make adapter harnesses or buy them yourself. I made 2 of my own adapter harnesses for the sensor but bought the one for the S5 ECU connectors to the FD PFC unit (3 plug to 4 plug IIRC).
Currently I think there are only 2-3 people in US running the AP PFC on an FC successfully and I'm one of them. There is maybe 1-2 in Canada that I know of as well.
Check out the PFC forum for more info.

I made a PFC work in my 87 NA converted to a TII, you need to goto the junk yard and find a MAP sensor, oil sensors, etc from an FD. cut the engine harness from an FD or find some of the female ends of the engine harness, then you will need both pinouts for the FD and FC and cut your existing harness with confidence cause you cant turn back after that or your just gonna go crazy, hardwire the corresponding pinouts together and wire all the FD sensors in place of your existing sensors, This is only breif, its very similar to wiring an S5 motor to and S4 body, but if you have a pretty good knowledge of elecrical then this can be pulled off, my suggestion is if you have time to look this deep to fiding out if PFC will work in your car then you should just get accustomed to Haltec, but if you are presistent like me than you will want to do the conversion to make it work. but Haltech will be a hellova lot easier, but I leave it up to you
Good luck!

Also wondering why you converted to FD oil sensors (I'm assuming level sensor because that's the only one) since the PFC reads nothing that I know of concerning oil.
