Programmable Engine Management Systems: Wiring Diagrams/Functions/Limitations

[blueroadster]

I am putting together an Excel spreadsheet that captures the wiring details when installing a Programmable Engine Management System (PEMS) in a piggyback configuration on the 2006+ Civics. I have the pinout descriptions for the stock Engine Control Module (ECM) (details on the stock ECM can be found in this thread) already populated and am looking to acquire more information to complete the spreadsheet and this post. With that being said, I am hoping to receive input on the following:

1. A concise list of PEMSs that have an application available for the 2006+ Civic (information to be incorporated into this post).
2. A concise list of PEMSs that are adapted/being adapted for the 2006+ Civic (information to be incorporated into this post).
3. A concise list of PEMSs that are in development for the 2006+ Civic (information to be incorporated into this post).
4. For each PEMS, a description of the engine management functions provided/limitations when using on the 2006+ Civic (information to be incorporated into this post).
5. For each PEMS, a pinout description and wiring diagrams/instructions (information to be incorporated into the spreadsheet and later added to this post).

PEMSs Available: AEM F/IC, Greddy e-Manage Ultimate, Greddy V-Manage, Vishnu Exede...Others?

AEM F/IC:
Overview: The F/IC gives users with OBD-II race vehicles and non-factory forced induction systems the ability to retard ignition and deliver accurate amounts of fuel without the need for outdated FMUs or “boost hiding” controllers. This system works parallel to the factory ECU preventing tuning limitations due to complex factory timing patterns.

Pinout Description/Wiring Diagram/Instructions:
The below images include extractions from the Excel spreadsheet that I put together from reading the AEM F/IC installation manual. I am hoping that someone that has the AEM F/IC installed on their 2006+ Civic can verify the information, identify what wires are not used, and fill in the areas with question marks.

Greddy e-Manage Ultimate:
Overview: The GReddy e-manage Ultimate is as close to a stand-alone management system as you can get while maintaining the best features of a "piggy-back" engine management; an economical price, the usage of existing sensors, the ability to easily alter factory settings and not having to tune from scratch. But unlike the original e-manage, the Ultimate is more refined, requiring specific application usage (which we are constantly adding application updates that you can download FREE via greddy.com, Tech WebPages.) The benefit of this is, the included PC-based USB "Ultimate Support Tool" allows for even finer tuning capabilities, improved flexibility in fuel & ignition control and adds impressive data-logging qualities to make tuning quicker and easier. The increased number of input and output ports of the Ultimate, along with new built-in adapters add many new options to the unit. In addition to standard e-manage airflow-based adjustments, the Ultimate version includes new and upgraded features. The Parameter Set-up, tab menu format of the Ultimate has improved direct Map control for adding and subtracting Fuel and Ignition. The ability to switch between 2 preset tuning Maps (i.e. Street or Race program) via externally mounted toggle switches. There are Maps for Individual cylinder adjustment for both Fuel and Ignition. There are also options to convert injection and ignition systems (i.e. group or sequential injection and group or individual fire ignition.) An Airflow Output Map option even allows for airflow meter elimination. And when used with a wideband A/F Meter, the Air Fuel Target Map can self-tune an Injector base tuning Map, to speed up initial tuning. There are also built-in Boost, Rev and Speed Limiter-Cut features. To create super smooth operation, there are various fine tuning Correction Maps to adjust for Throttle Acceleration, Vehicle Speed, Water Temp, Intake Temp, Auto Trans Shift, Anti Engine Stall, and Idle. To further aid in tuning, e-manage Ultimate’s improved integrated Monitoring, Map Tracing and Datalogging features far exceed any other piggyback controller on the market. Even when not connected to the software, 8 channels of datalogging (at 20msec intervals) can be recorded and stored to be reviewed later. With the Support Tool connected, over 30 channels can be covered. Other new features include: Improved RPM recognition, Warning Settings, Password Protection for individual tuning Maps, NVCS (Nissan), VTEC (Honda), O2 Feed-back, Clean Fouled Plugs, and numerous others in future updates. Ideal for optimizing and fine-tuning for performance products like Exhaust, Air Intake, Intercoolers, Boost Controllers, and Turbochargers, the e-manage Ultimate fills the gaps between conventional piggyback and expensive stand-alone engine managements. All installation and tuning should only be made by a trained technician with proper air/fuel monitoring tools. (Some or all functions may not be compatible with some applications).

Pinout Description/Wiring Diagram/Instructions:
The below images include extractions from the Excel spreadsheet that I put together from reading the Greddy e-Manage Ultimate installation manual. I am hoping that someone that has the Greddy e-Manage installed on their 2006+ Civic can verify the information, identify what wires are not used, and fill in the areas with question marks.

Greddy V-Manage:
Overview: The V-Manage, Variable Valve Timing Controller was designed by GReddy engineers to take advantage of some of the modern technology OE Manufactures* are now commonly incorporating into their latest engines. Based on the intuitive controls, datalogging and Maps of the e-manage Ultimate software, a tuner with a laptop computer, can now alter the factory’s ECU control of valve-timing at any RPM and load to optimize power output and fuel economy. However by purchasing GReddy's application specific V-manage Kits, you can simply "plug & play." V-manage Kits, include the V-manage, CD software, Plug-in Harness with adapter, and Pre-programmed MAP to optimise cam timing for increase horsepower, toque, and boost response.

I have the day off so I figured that it would be good to spend the time to assemble information that is out there to gain knowledge on the various systems being used.

I'm hoping that this thread will be thorough and concise enough to help both others and myself at some point. I've read through several installation manuals and the information presented is rather generic in a sense. Having more detailed information would help in the wiring and knowing what someone would be expecting if they chose one system over another.

I've already added the Greddy e-Manage wiring information that I have read and am working on the spreadsheet for the MoTeC to add that information as well.

I would really appreciate it if others could chime in with their knowledge so that the information presented in the first post is spot on.

[blueroadster]

Added information for the stock EMS wiring.

[bizzybearfigiblue]

nice info... i'll stick this thread... even tho u could've done that yourself

[blueroadster]

Added information for the AEM F/IC.

[the1stpower]

i was wondering if anyone could help me with me E-manage or is there any other way to tune it because its running like crap or if there is any other ECUs out there for a 07 civic sedan. i have the greaddy turbo kit with 550 injectors and a bunch of other parts. but please message me if you have any info on tuning or new ECUs thanks

[blueroadster]

You might have better luck if you start another thread on the issue that you are having with the e-Manage.

E8 Wiring Diagram

I only know of one limitation for the Haltech EXv2 ECU is knock detection.

[blueroadster]

Thanks...I edited the tags in your post for the link and will add the details. The information on that page however is a lot easier to understand than others that I have seen.

BTW, MoTeC does not have knock detection either for several reasons. It can always be added though which I'd guess the same can be said for the Haltech.

Not worried too much about knock since Mo is a conservative tuner. At most with Pump I will run 23psi with the Meth kit. Race = sky's the limit.

[blueroadster]

Cool...I'm hoping that more people can assist with tracing the wiring used on their car. I know that several systems include a PnP harness, but it would be helpful if we had an understanding of how each was wired.

There is another thread in the forced induction area regarding the F/IC and people running into problems with the wiring. Hopefully, someone that has it installed correctly can trace the wires on their car so that others using the F/IC can verify if something is wrong with the wiring on their car.

With the Haltech, are you going to have it wired into the car so that it drives the engine where the stock ECM is retained to drive the gauge cluster, instrumentation, and other CAN devices?

Cool...I will be doing the same and would like to compare notes at some point. It would be nice to completely replace the stock ECM but doing so would take more time and cost a lot of money trying to figure out Honda's implementation of the CAN protocol.

The one limitation with the setup would be that the stock ECM will likely trigger the check engine light and throw some codes since it won't see all of the sensors and control the running state of the engine. I'm hoping that some of the unused outputs can be used to send data to the stock ECM to keep it happy. I have heard also heard that almost every Dodge Viper running the MoTeC uses the same kind of configuration. I'll have to check those boards as well to see how the wiring was done and if they were able to keep the stock ECM happy at the same time without triggering codes or a CEL.

[07CivicMD]

Good luck. Have to wait and see in the next few weeks how the stock ECU handles the Haltech. I will keep you updated once it's installed.

Cool...Let me know how it goes. I got most of the wiring for the MoTeC figured out (just waiting on confirmation for the DBW, REF, and SYNC connections). I'll be using several of the stock sensors as inputs and a few of the outputs on the MoTeC to mirror the same signal back to the stock ECM to try and keep it happy.

The stock ECM will likely not like the signal changes with the new tune so I'll probably have to either see if the programming in the ECM can be modified to accept the changes or have certain ranges turned off so that they don't trigger a DTC or CEL when an OBD-II scanner is connected.

[blueroadster]

Bump...Added a PIC of the engine wiring harness. It would be great if others could chime in to provide some more technical input to this thread.
