any one runnin proefi ecu?

http://www.proefi.com/Pro_128_ECU.html

I copy paste this from sound performance's post on another forum,
I am thinking of going with this ecu, if I program all those safe fail's,
with the needed sensors end run e85 sensor it should be good insurance,

Here is some info on the ProEFI:

12 Injector drivers - All with built in Injector drivers!! Perfect for a twin injector setup on the Supra!!

16 Coil Drivers - Yes 16!!! No more waste spark!!

32 Analog inputs!!! - There are 32 analog inputs which will be preconfigured for anything you want to do... I.E. plug in a fuel pressure sensor and it automatically activates the trims associated with it. Put a Nitrous pressure sensor on your car and the computer trims fuel accordingly to bottle pressure!! You can datalog everything imaginable!!

10 Low side driver outputs - You can configure these to do whatever you can imagine. Also these will all support 4+ amps each!!

Built in wideband!! - That says it all!!

True volumetric efficeincy - So things like injector and pressure changes don’t have to be calculated and multiple maps changed, it’s all done in the background by simply entering your injector size and base fuel pressure. Actually knowing the injector size and fuel pressure, this allows us to make instantanious feedback changes to things like fuel pressure not staying constant, without relying on the O2 sensor for delayed information. Changing fuel type is as simple as entering the stoichiametric ratio for the fuel used.

Fault coding – Check engine light will tell you fault codes to help diagnose problems. Actions can be assigned with the fault codes. I.E. low oil pressure triggers a fault code, and activates a low rpm limiter. O2 sensor faults will automatically turn off block learning and closed loop feedback. Also the fault codes will be the same as the original ECU!!!

Traction control – multiple comprehensive traction control strategies including defined wheel speed differential between driven and non-driven wheels.

True knock sensing capability with specific knock frequency detection based upon the specific engine being monitored.

Multiple failsafe conditions making it nearly impossible to damage your engine in the case of tuning errors or mechanical malfunctions. I.E. lean, and knock conditions can be used to turn off nitrous, shut down boost etc….

O.E.M. manufactured ECU’s – The ECU’s are built by an O.E. manufacturer, so all ecu are 100% tested for vibration, temperature, loading etc… BEFORE you install them into your vehicle. Pro EFI ECU’s are as reliable as the factory units you take out. No more being stranded on the side of the road, or waiting weeks or months to get and issue repaired with the confidence of rolling the dice.

Drive by wire capability!!

Nitrous control:

Up to 4 stages!!

Control by speed, time, gear etc.....

Just enter the number of jets, jet size and target a/f and it does the rest!!

Add a nitrous bottle pressure sensor and it adjusts accordingly to pressure!!

Unlike other ECU's, you can target different a/fs for Nitrous with this unit in closed loop, or open loop, since the computer is based soley on V.E. it doesn't rely on the O2 sensor for hitting the desired a/f ratio. It does this based upon volumetric efficiency and desired equivelency ratio. Therefore there is less work for the O2 to do in closed loop, eliminating the chance for lean spikes typical of running nitrous!!!!

Fuel pressure compensation:

With the simple addition of a fuel pressure sensor, the computer will monitor and compensate for various fuel pressure. Lets say that you have a pump that is tired and your fuel pressure is not rising 1-1 any more. The computer will know and add neccessary fuel. Also if the pressure really gets unstable causing the computer to add too much pulse width, it will trigger a check engine light. It can also be set to initiate fuel cut, turn off the boost control, shut off NOS and lower the rev limiter. These safe guards can be triggered by the fuel pressure alone, by O2 activity or a number of other things!!

Boost Control Strategies:

Will be able to utilize dual solenoids to control pressure to both the top and bottom ports on any wastegate. This will give you VERY accurate control!!

Will be able to control boost by speed.

Will be able to control boost by time. Therefore if you spin the tires, and the vehicle speed sensor puts the boost map into a zone for higher boost.... the computer will know that it is wrong and hold the boost down until a certain amount of time.

Will control boost based on traction control. Traction control will be based on wheel speed differential!!

This computer will also know what gear you are in by simply entering gear ratios from the service manual, rear end ratio and tire size!!

Lean condition safety features:

In the case of a lean condition under certain circumstances (IE load, time etc) the computer can be programmed to shut down nitrous, lower boost, initiate fuel cut, initiate a rev limiter for a programmed duration of time until safe conditions return. This can also then be programmed to throw a code and activate the check engine light.

Misfire detection:

No more guessing if you have a misfire. This computer will tell you which cylinder and how often it misfires!! Think about how valuable this will be!! You will know instantly when it is time for new plugs.... or a coil pack is going bad....etc!!


20 channel thermocouple capability:

Yep..... 20 channel!! Put one in every runner..... downpipe..... anywhere you can think of!! This is critical in tuning an engine to run exactly the same on every cylinder!!!Read more at http://my350z.com/forum/forced-induc...pro-efi-3.html

no one using it?

I know larry at sound prformance uses it on supras. And I also believe Ray at PFS is using it on his 350z. You might wan to contact Ray and ask him if he has used it on a rx7. I have heard very good things about this ecu. Hope this helps

yep thats how I found out about it from supra guys
thnx

Just because it has a lot of drivers doesn't mean that the software can run trailing spark on a rotary engine. You should check with the vendor on this.

A lot of those other features look pretty good.

acording to them it can and theres rx7's with proefi,
I was hoping someone from this forum so they can share
their experience,

anyhow I am going to take a chance if I can't make it work I'll
use it on one of my piston cars

Bump.... heard a little about this system today and wonder if anyone is using it? Sounds pretty incredible.

Bump again. It's been over a year with no replies. Just checking to see if anyone has taken the plunge yet. The manufacturer is local here in Phoenix, so I may stop up and see them.

Anyone try one of these yet?

I’ve been researching ECU’s for my application for a few months, I too am seriously considering the Pro E, and I really like the flex fuel controllability among the other features. Tough choice between that and the Link G4. If I wasn’t so bent on running E85 it would be an easy choice.






For sale: FJO complete water meth kit

Well today I took the plunge, I bought the P/E 128 and will running on E85.
I need to get the motor off the stand an in the engine bay along with the supporting mods.
Looking forward to the challenge, should be fun.

If you don't mind me asking, where did you purchase? What options did you get? Hope to see a full writeup and review.

I bought the P/E 128, a plug and play wiring harness for the FD and a CAN cable kit. I also just bought a GM flex fuel sensor at Amazon for a great price. I’ll use all the features and safeguards along with the flex fuel sensor, the ecu automatically adjusts fuel, timing, boost based by the ethanol content in the tank. I’m still colleting a few items needed for the build. My engine is on the stand but I’m hoping to get the motor and trans in the car next weekend then build around that. Once the motor is in I will try to update my build along the way.

Yesterday my EMS showed up at the door step thought I’d share. From the preliminary looks of things it might be a bit of a challenge finding a place to mount the ecu in the passenger foot well area, I’ll have to check it out. The PnP harness is very nice and should provide some mounting flexibility. Now if I can only get in the garage to work on the car….

Joe,

looks good... maybe we will be burning rubber together this year:)

good luck, 2012 is going to be interesting.

howard

No maybe's about it, we're going to do it!
We both have big challenges ahead of us but we'll work thu it :icon_tup:

Looking good. I know that PRO EFI is interested in breaking into the rotary market, so I'll be interested to see if you get any "additional" attention or support from them as your project progresses. Please keep us posted. Also, I was under the impression that there were several additional sensors that needed to be purchased. Did you decide against these, or is this all that's needed for the FD application? The one feature I find very interesting is that you can set the unit to sense wheel spin off of your wheel sensors and it will automatically adjust. Built in traction control :)

I'm ordering mine this week. :D

RCCAZ 1, P/E has been very helpful regarding the questions and concerns I had while making my decision. As far as I know I don’t need any more sensors other that what I have, unless I forgot one or two. The ECU uses the current sensors and features available to the FD (including the MIL) as well as optional ones that I will wire up before startup. I had a flex fuel sensor along with a pressure sensor I will use to log fuel pressure, EGT’s, fuel pump (s) control (very nice feature/safeguard), traction control, etc.

Excellent product with great support when needed. I'm finishing up an street car (FD) with a Pro128 now that is seeing 10-11k rpm. I'm still tuning it but the results have been great so far.

Excellent! :icon_tup: keep up posted on your results.
Thanks for sharing

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! :(

i been hearing a lot about this ecu from my friends with supra's i just wanted to know will this work with a 20b?

Yes, from the conversation I had with Jason over at ProEFI last week, this will control a 3 rotor or 4 rotor. :devil:

This is one of the main reasons I choose this ECU as I wanted to future proof my setup in case I decided to change my setup later (<And I always do! :D>)

very nice

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.

Thanks. Yea, the local Supra guys were saying close to $5K out the door for everything. Just wanted to verify if the FD cost was compatible or slightly less. Guess I'll just stop by their headquarters and dive in a little deeper on actual costs.

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.

Thanks for that feedback and vote of confidence Steve. Have you had the opportunity to tune this unit on an FD yet? Just curious.

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!

This is actually a street/show car runing a 2 rotor semi pp, with a GT42R using C16 fuel.

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.

Final results yielded just over 810 rwhp. The vehicle runs flawlessly.

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
