New engine management for sale
Category: Engine - Electrical
Price: $700
Private or Vendor Listing: Private Listing
Part Fits (you may select multiples): Others, Series I, Series II
Location (US State/Canada/Int): MD
Item Condition: Used
I am re-listing this after having sold all of my other parts in previous posts, so up for sale is a new Electromotive TEC3r ECU, it has never been installed or programmed but is missing the harness which can easily be obtained for pretty cheap. Here is the description from electromotive that can explain it in better words than me.
****The new TEC³ ECU incorporates the winning features of our previous TEC-2 system while adding an abundance of new features and a powerful new processing platform. Electronic Fuel Injection (EFI) control and patented digital Direct Ignition control is standard hardware for every TEC3. The anodized, laser-etched ECU with waterproof OEM style connectors and harness may be mounted under the hood or in the passenger compartment and will activate separate multi-coil DFU’s (Direct Fire Units) mounted adjacent to (or on) the engine. Standard features built in to the TEC³:
PC programmable and configurable for 1, 2, 3, 4, 6, 8, cyl. engines and Rotories with a 12 cyl.and 6 cyl dual plug option
Operate in Open or Closed loop
Run True Sequential, Phased Sequential or Simultaneous Injection with individual cylinder trim
Configurable for TBI, MPI, TPI and individual throttle bodies
Additional Injector Output Drivers built-in.. Run Low or High impedance injectors
Full 150 mJ of Spark Energy directly to the plugs without misfire
New Dual Rev Limiters with ‘Triple Smooth Technology’.. 1st step retards timing to a negative -12º degrees.. 2nd step cuts coil current in half.. 3rd step coil current and fuel are cut-off.. all three steps occurring within milliseconds!
Waste Gate (Boost Control), Nitrous Control with up to 4 stage retard available
Four Programmable GPO’s (General Purpose Outputs) to control or activate VTEC, Shift Lights, Water Pumps and Fans, A/C Compressor, Torque Converter and more.
New Programmable Adjustable Electronic Tachometer Output
Uses primarily GM type sensors
Diagnostic monitoring with codes issued through Check Engine Light
Easy to install bolt-on Trigger Wheel and Mag Sensor Kits available for many applications
Made in the USA
New On-Board Data AcquistionAdjustable Sample Rates up to 100 samples per second Simultaneously record data from up to 25 inputs including: Air/fuel Ratios, Injector Duty Cycle and Pulse Width, RPM and Throttle Position, Gear Position, MPH, Boost (manifold pressure) and much more!
Additional configurable Digital and Analog Input Channels View Multiple Data Graphs side by side or Graphs may be overlayed for comparison Graphic Screen Displays may be Printed and
Data may also be exported to a Spreadsheet program for further analysis Data Logging can be started and stopped manually using a switch, or the system can be configured to automatically start and stop via values pre-set by the user.
The venerable TEC³ has been revisited.
Your TEC³ computer just became even more powerful with the release of the new TEC³r...
One controller for all applications - no longer are there two variants, but both configuration options of the TEC³ std and 6/12 have been combined in the new TEC³r.
New configurable Injector Outputs allow either one or two high performance low resistance injectors to be used on each of the 8 injector drivers. The new starting circuitry from the XDI has also been incorporated.
any other questions or concerns, just PM me and I will be happy to answer!

I assume by APV you are referring to the auxiliary port valve? Im not very well versed on this subject, but will this unit not work for it? bc I have seen 20Bs using this system, or is that different?

Teamrx8 do you know the answer to his question? I am also curious to know.
Comcamjoe... I am not looking now but I will be in the spring and i doubt you will have it then. Good luck with the sale! If you find out the answer to teamrx8 comments let us know.
Thanks,
Stephen

This is what I have found about the APV from an rx7 service manual. I am making the assumtion the the APV works the same on the 8 but I do not know for sure, still looking. But according to this the APV is controlled by air pressure, not the ECU. So I don't see how this will have any effect on the engine by using this unit. Granted I am no expert, so I would love some input from the many ppl who know a heck of alot more about this than me. It would be greatly appriciated. In the mean time here are some snips about the APV from the service manual that I was referring to.
-"AUXILIARY PORTS
The auxiliary port valve system allows a better flow of intake air by opening an auxiliary port in addition to the primary and secondary ports. The opening of the auxiliary port is controlled by the auxiliary port valve. At low engine speeds, the auxiliary port is closed. When the engine speed is high enough and under certain conditions, the valve starts opening the auxiliary port."
"This above describes the operation of the auxiliary port valve system. The pressure line going from the air pump to the actuator exists only on the mazda rx-7 89-91. On the 86-88, the pressure line to the actuator is teed into the split air pipe (see emissions section under secondary air injection). When the auxiliary port valve rotates, the auxiliary port opens. The more the valve rotates, the bigger the actual port opening becomes. The rotation of the valve is controlled by an actuator which is itself pressure controlled."

Ok so just got off the phone with electromotive and Ken Scheepers (who has extensive experience building renesis engines for drag and race) and have found the following. A- I underpriced this unit lol B- no this unit does not control the APV, BUUUUT, no other aftermarket ECU does. It requires a stepper motor to be installed to control this valve. Now most people go with lesser ECUs for renesis builds, such as the electromotive's GT model. Now as I was told by electromotive, "the tec3r is actually more ECU than you would need for 2 rotor" but is MORE than capeable of running it at it's maximum potential. Now if you have a 20b dream in the future, you will NEED the tec3r anyway, so it will save a significant amount to go ahead and spring for it now. Soooooooo now I'm debating on if I am not asking enough for a unit like this? I dunno, but either way, there's the answer lol

This is a very good price, free bump with some info. Motec does run the APV for sure. That said, my car is running on electromotive tec3 (not even 3r, which I paid a lot more for). VDI works, my apv is wired open. Fine for race only, should not see any rpm lower than 6k anyway. Probably not too good for a normally aspirated street car. Who can build an apv control box? I thought sheepers had one.
I would have bought this if I had seen it 4 months ago.

The MoTeC can control the APV, only mentioning it because of the prior statement that none do
I've heard a lot of talk about a separate controller, but have yet to see anything that concretely backs the talk up
Anyways, not knocking the system because as mentioned in certain apps it will be ok, but more than a few people here don't know about the APV issue and it's preferrable that they don't learn the hard way

thanks tilt, hows the JIC kit working out for u?
team RX8- I'm not too familiar with the motec, but I did find add on steppers. after another call to electromotive I was told you could probably control the APV with one of the GPOs from the tec3r (program it to activate a servo at a given rpm range maybe?) I highlighted it in the description above. but anyway, I was only going off of what I was told by ken. didn't mean to make a false statement, but the stepper motors are easy to install from what I have gathered.
