very nice

Ray, what features are you implementing with the ProEFI setup? Are you using the dual knock sensors, traction control, flex fuel, etc...
I tried getting ahold of you last week, but your line was always busy! :( Closed loop enabled features for this car. -Fuel Pressure -Exhaust Back Pressure -Knock -EGT -Traction Control -Boost Control I'm only using one knock sensor on the front housing, as I'm not a believer in its ability (knock control in general for high hp rotary applications) to save the engine. However it does work well on piston applications we used it on. Hopefully I will be able to this RX-7 back on the dyno later today to finish up the tuning and configure the boost control. Let me know if you have any other questions. I am a bit hard to get on the phone at times, but if you leave a message I'll get back to you, email is also another way to reach me. |
Is there any way we could get the firmware or basemap that we need to see the options for rotary engines? I downloaded it and I've been messing with it while I'm piecing together what I need but there's no basemap for rotary engines to start with. I know sound performance said they would load one before they shipped the unit to me but was wondering if I could get one before that.
Also, do you think the problems you've seen with the knock sensors not working well enough on the rotary are because of placement or just because once we've changed so much on the engine the knock frequency is so different and the noise is too much? |
So, the ECU itself costs $1879. Is that the price for a complete system, or are the harnesses and sensors extra? What can I expect to pay for an FD compatible system?

That's the price for the ECU only! You have to purchase a harness and additional sensors. Then you have to install it or pay someone to install it for you and then tune it. You are honestly looking around $2,500 at the lowest possible entry price it goes up from there depending on the options and installation. Not cheap by any means, but when you compare the feature set for the price it's pretty hard to beat if you ask me.

Jason Siebel (owner of ProEFI) was the head engineer that developed AEM EMS. He used to have a fast Rx7 back in the late 90's so he knows Rotaries well. There're alot of great features. You're basically getting a motec without paying the motec options. You can't go wrong with his EMS.

Just thought I'd give an update on the 2 rotor with the Pro128 EMS. Everything is coming together, and I'm nearly done.

Wow... knocking on 800 RWHP out of a 2 rotor is impressive. Amazing. How was the install? Any challenges? How's idle and driveability. Very nice!!! What turbo, porting and fuel was this?? Street or purely racecar?
Thx! The whole build has been pretty labor intensive. The ProEFI is just like any other ems system in regards to building the wiring harness. There were some struggles in the beginning, and I ended up building crank simulator to "run" the car with it not actually running. After a lot of time with the simulator, oscilloscope, and timing light Jason@ProEFI wrote new firmware to fix a few things and added in a few other adjustment tables. The good news is I've already put in the time to "debug" the system and I can confidently say it works very well. The startup, idle, driveability and enrichments are all excellent, but just like any other EMS, proper tuning is essential. You can have all the correction tables you want, but not knowing how to utilize them correctly always ends with sub par results. http://youtu.be/goa5k2efdrI |

Thanks for the replies ray. looking real nice
|
wow nice numbers
|
Cool, We have our sub forum :icon_tup:
Thanks! |
Ray,
What trans? if the stocker what has been done to it to handle the rpm and torque that this gem of a motor/ecu combo is putting to the rollers? |
By looking at the specifications, anyone have any drastic reasons NOT to go with the pro48 on a 2 rotor single turbo instead of the pro128?
Some main differences I can see... -Pro128 has 2 Built in UEGO controllers, pro48 requires external -Pro128 has 34 analog inputs vs 14 on the pro48 -Pro128 has two speed inputs for traction control, the pro48 does not -Pro128 has PnP e85 sensor capability, pro48 will require an additional box |
Sounds like the pro128 might be worth it. E85 and traction and eugo might be all worth it
|
What do you guys thing TEC3r or a Pro EFI unit. I could sell my TEC & Raclogic, and probably come out ahead if that is a better option...
|
One of the best aftermarket ECU's imho. I have used one in a Supra and a 996, next will be 13b for sure.
|
I'm interested in this EMS too, although I may try it on another car first to get used to everything.
|
updates?
|
I sold my adaptronic pnp and just order a efi 128 box. Going be using traction control, flex fuel, fuel and oil pressure sensors, dual egts and might do back pressure to. Keep you update
|
Grinch, I have a PNP Pro Efi harness for the FD, pictures above. I went V8 so i dont need it, I was going to post it up for sale this weekend. Pm me if interested. Thx
