Another REW swap in the works, ECU questions...
I've been reading through pretty much EVERY REW swap thread I've come across, and unfortunately I'm just not finding the information I seek. I've done this for the last Alright, so I've pretty much figured out everything as far as what I'll need to have a proper running, reliable REW under the hood, but I'm torn between choices when it comes to what ECU I wish to use. I want to stay away from Microtech and Megasquirt (personal reasons, so don't try to talk me into them). Here are the units I'm considering.
1- Haltech Platinum Sprint RE w/ RX-8 harness plug
Haltech Platinum Sprint RE with Plug and Play Harness for Mazda RX-8 - Mazdaparts.com
2- Haltech Platinum Sport 1000, will require me to have a custom harness made. Only downside I see is cost, as I'm trying not to go too crazy.
3- Adaptronic Plug-in Select as seen here, though, I'm not certain this will work

Any input from anyone running either of these ECU's with an REW is SUPER greatly appreciated, as well as any reasonable alternative ECU configurations.
Thanks

I haven't read up on whether or not the RX-8 PnP unit from Adaptronic will work with the swap. If it will work, I'd go with that one, if it won't, they have a wire in ECU as well. I'm using the e440 Universal Select on my build but I'm also not keeping any RX-8 functions either and I'm using an REW front cover.

Well, my plan is to retain most of my functions, as it will still be a street car. I have pretty much decided I'll use the FD front cover and oil pan, which means I'll have to figure out a means to mount the 8's AC compressor, but I'll jump that hurdle when I get there. I also plan on running the Renesis trigger wheel w/ FFE's Hall sensor, if that's even possible. Again, an easily cleared hurdle I'll get to eventually.
dannobre- What ECU setup are you running exactly?
Arca- Did you retain the stock RX-8 harness, or have one custom made?
Team- Never saw that thread, but from the looks of it, his issue was/is related to the MAF more than ECU correct?

That, I do not know. I've only ever seen one REW swapped 8 in person (firecran's) and I didn't actually look under it at all, let alone ask any questions like these lol. At that particular point in time, an REW swap wasn't on my to do list. If it ends up being an issue, I guess I could go dry sump.

Im using a GSLE front cover modified for the RX8 trigger...and an LT9
Mine is a track only car so the things I hated about the old Microtechs dont matter. The Microtechs ignition triggers are much more stable than a lot of others. All the fast high power drag cars use them
I gutted the stock engine harness to just the sensor wires and wired the flying lead harness in.
If you plan to track the car. .. think drysump. The oil pans have a difficult time with oil slosh at higher G loads

The REWs oil pan does hang alittle bit lower but it's never scraped on anything from being to low. And my car is lowered too, not slammed just respectfully lowered.
As far as the front cover, well any combo will work.
They've all been documented some where on here.
Just depends on what you wanna do.
Love seeing all these REW swaps!

This is a picture of a spare engine I have with the FFE trigger and AC. Although you'll notice that it a FC cover, I also have the same exact setup for a rew cover. The oil pan will protrude below the rx8 lines, but I believe it's not that big of a issue. At first I was using the stock bre pan and that was even lower and a huge problem. Then I chose to mate a bre pan with a stock rx8 pan, and it came out pretty good. BTW, I suggest you go Haltech p1000.
a mag sensor is required to keep the OE computer happy running the dash and EPS, think I recommended the Hall sensor before but it can only be used for the aftermarket computer, not the Mazda computer

I do plan to attend some HPDE's once the car is up to snuff (Sebring, Daytona, Road Atlanta, and Circuit of the Americas) and might eventually try my hand at some NASA Time Trial events, but we'll see.

And yeah, the more I read, the more I'm leaning toward the Haltech PS1000. Although, I'm not looking forward to wiring, so I'll probably just pay a friend of mine to take care of that.

I'm still leaning slightly toward the RX-8 cover, but I'm not opposed to the REW cover either. Plans are to retain PS, AC, dash, TCS/DSC, etc. The car will be driven frequently, so it needs to retain some comforts, but also be reliable.

First i wont to say you dont need a programible ECU to do a swap. There great for race and drift aplications when the car needs to be tuned for injector size , ignition timing ext . Plus you still have to make the conections on the harness if it has open leads , or pay something like $2300 for ECU with prefab harnes . You can buy so many other things for your car with the money . With some help and guiedance from Mazdatrix i have swaped a complete bone stock fd3s in my rx8 , twin turbos and all.

I left the rx8 ECU in place ,my fd harnes comes through the fire right by the brake booster , the fd ECU sits right above the steering colum , after that you take a couple of leads from the x05 connector like injector power / solenoid power ext and i did this with x11 x12 for coil power ,igniter trigger leads .B1-01 ECU conector ,take it off any Japanese car of the same year witch gives you the open leads to make up important connections like ignition input igniter triggers ext . Its fed all by relay via toggle swich.

A stock FD ecu barely runs on a stock FD setup with new exhaust and intake. How do you think it will run on an RX8 with different intake and exhaust? Might sound like a good idea. .. and be a way to save money. .. but it is doomed to fail. .. especially when you get tired of power level and crank up the Boost a bit. Don't forget the FD setup stock Didn't make much more power than the Renesis

Getting the fd to run in a rx8 in its stock form isn't failure , its a starting point , for the intake and exhuast its original . And yes there is a cap on power and that sucks . But for you , Mazdatrix sells the Haltech plug and play setup or with open leads for a $1000 . I think its the sprint re 500.

Being a grass roots drifter with no budget and big passion for rotary engines , you do what you gotta do to get on the "track". What i dont have in money i make up with knowledge and understanding of the mechanical fundamentals that make the engine tick ......
