Jason, I so wish I can understand that stuff. All sounds liek grble to me, but that's why I'm here! To learn...so witht hat said and done, thx for the info. Anyway you can disclose the info as to why the unit was delayed?

 

The units were delayed because they are not ready to be shipped.

Jason.

 

Realistically are we talking about a major delay, like April 2002???

Ken

 

Jason,
will the unit control 1600cc injectors? Is there an input for those?

Thanks

 

What kind of features/compatability for the 'generic' unit (for us FC guys?)

 

Yes.

 

The same.

 

What 3bar map sensor do you recommend??

Ken

 

Jason, can you get into more details about the knock control features.

Is the amount of retard user programmable with respect to amount of knock detected?

How does the unit advances the timing after encountering knock, is this also user programmable?


Thanks in advance, Wayne.

 

Delco

 

It is all fully user definable, amount of retard per volt, amount of fuel added in %/per volt, and rate to reverse the process.

Jason.

 

This is such a wonderful piece! I can hardly wait to get my hands on one! For tuners like me, lots of spare inputs and outputs are a wet dream! I might even trade in the TEC for these prices. FC owners -- I'll be glad to fab up custom harnesses for direct plug 'n play. Oooohhh.... so many inputs and outputs!! Download the demo software off the AEM website, and poke around. It's a little cute 'n fluffy, but still loaded with cool features. Even the auto tranny control looks fun -- I'll have to crank up the settings on the next car that comes in for an auto->5spd swap and see what the limits are! Maybe I'll have to 'expense' an auto tranny to find the real limits; it will be interesting to find the physical limits of the tranny with powerful software control. No more progressive NOS controllers ever needed again... no more RPM window switches... no more external staged injector drivers on TEC's due to insufficient numbers of dedicated drivers... and all those inputs and outputs... did I mention those already? I'll be sure to post a detailed writeup when I get one in here to play with.

Does your knock function retard both leading and trailing?
Have you used the traction control feature on your RX-7?

 

Delco? I assume that is GM which is a 3 bar which Dave at KDR recommends. Says it cost $45.

Again I ask "WHEN WHEN" can we get this great product?????

Ken

 

The knock sensor will control whatever you tell it to, leading and trailing front rotor, rear rotor etc...

I have used traction control on my 7 it works fine

You can get the system as soon as it's available.

Jason.

 

Will you provide some technical assistance to hook-up the traction control system?

Question on sensors: Is changine a sensor as simple as telling the ECU what sensor is in there? Example: Changine the stock coolant sensor to a GM is just telling the ECU that a GM sensor is in there? Basically, I am curious about how you tell the ECU which coolant sensor, air temp sensor, boost solenoid, etc etc are in use. I have a feeling that all become clear if I could only see that ECU menu from the demo software ......

 

There are tables to enter values of what the actual signal coming into the ecu is equivelant to. I.E. if you have a raw signal coming in from a sensor that you know is say 75 degrees F, then you go to the appropriate sensor table and enter that value in the table. As for the boost controller you decide to use, you just determine what pulse width equals what boost, and enter those values in the boost control tables.

This leaves us very open to being able to accomadate any type of sensor.

Jason.

 

So then are the preset values included for popular sensors?
I remember something about boost by gear from the supra forum ... how about dual boost settings or boost by rpm?

I am leaning toward this product but I just recently spend lots of time rewiring my car for the Haltech and I want to be sure it is worth it. I don't suppose you could send me a full copy of that software?

 

All of this can be configured, it doesn't come set up from AEM that way.

Jason.

 

I was taking a look at the ECU PINOUT Features for Plug N Play at the top of this page.
I counted 49 terminal IDs.
Does anyone see a pinout or terminal id for four stock injectors.
Does anyone see a pinout or terminal ID for coil #1(leading) or #2 (Trailing 1)or #3 (Trailing 2).
I saw a terminal id # 1V.
This was for coil 4.
This is definitely not plug and play.

Am I missing something.
This is bothering me. Engine Management means to give spark and fuel.
Someone please point out to me what I am missing.....

 

Jason,
Does this unit has more terminals than you listed?

 

If you take a closer look , the title is user features, the stuff you listed is a must be assigned type deal. They have to performe those functions. The stuff listed is user definable.

Jason.

 

OK. I am now calm. I want this unit. I just need some questions answered. Here is a question.
How many pinouts does this unit have?
Which pinouts are left for the injectors and the coils?

 

Jason,
I know on many ECUs there is and issue with the units acquiring a usable signal for engine position and speed on so many different applications.
The Haltech E6k has built in internal reluctor adapters with adjustments and software to help them use many stock sensors.
On the WOLF3D I used a capacitor to clean up the signal on a TurboII along with removing some teeth.
On the electromotive TECHII you have to run their crank wheel.

How Does the AEM EMS address this?
