I'm looking at a PDF showing the eManage wiring diagram and it appears that the injector connections are spliced rather than cut. Can that be right? If so, how does eManage change the injector duty cycle to add more fuel?

Also, since I already have the RPM signal (aka brown wire) hooked up to the Profec do I need to also connect it to eManage? Or only one of the two? etc.

Yes, all the connections (except for the MAF) are spliced and not cut. here is a modified installation diagram I made for the Mohdparts site that includes the TPS signal connection.

And it's 7-0-1 not 7-0-B, correct?

--Steve

 

Also, I don't have the software support tool (I didn't buy it). Does that mean I can't download the update onto the device?

--Steve

 

Yes, the rotary dials need to be set to 7-0-1

You say you didn't buy the Support Tool? Did you buy an E-01 instead?

You must have either the Suppport Tool (on a laptop), or an E-01 unit or else the eManage is of no use to you. Those are the only 2 options you have in order to enter/edit the information on the eManage to tune your maps. Do you have an E-01?

The timing harness is a cut....wierd...I could have sworn that the injector was a cut was well. That's why the harness has input and output colors....I dont have my car...and its been 9 weeks since I've even looked my emange...memory of my car is fading...need car...back from shop...quickly...i am dying.

 

I have the Profec E-01.

All the installation information that I have shows that the injector wires are spliced and the MAF wire is cut. That's how mine is set up. I sure hope it's correct

Take a look at the PDF that is in the link above and you'll see what I'm talking about. The only wire that has two seperate connections is the MAF which has an In and Out. All other injector harness wires were splices.

The ignition harness is all cuts.

Ok, cool! You'll be able to tune the eManage then <whew!>
I'm not sure about upgrading the firmware though. I believe that you need to have the support tool and laptop to do that. Sharif, any idea on that??

I have heard that the first time you hook up the E-01 to the eManage it will blank out all your current maps so make sure that you have the current map information (if there is any) written down so that you can reenter it all again.

-Chris

 

Yeah, there aren't enough wires out of the E-Manage for the injector wires to be intercepted. Still, I'm trying to figure out how it modifies fuel without interception.

--Steve

 

The only thing that I can think of is taht rather than intercepting the signal, it simply modifies the signal to increase the pulse width of the injector. Since 0.0 in the map fields means that it's using the stock ECU setting for that part, if you changed it to 1.0 for example, it would simply increase the voltage by whatever percentage 1.0 would be to the injector? That's all I can figure.

-Chris

 

ok..memory of my body in a contorted position under my dash is coming back. The injector harness is a splice, and the ignition harness is a cut.

Wonder how the eMange adds IPW without a cut, but the ignition harness needs a cut. Maybe becuase the ignition harness is delaying a signal, where the injector is adding to the signal, and doesnt have to delay it.

 

Steve if you need the support tool cable let me know. I got one.

 

Arrrgh!!!

Ok, now I'm frustrated. I connected the Zeitronix RPM wire to Pin# 62 and it works A LOT better now. However....

Now I do not have any TPS data in eManage! I did not even touch any of the wires and the TPS information displays perfectly inside the Zeitronix program.

I'm going to go watch CSI now and maybe get some ideas on what the problem could be

-Chris

 

Ok I've got the E-Manage all wired up and connected to the Profec E-01. However, for the life of me I cannot figure out how to do the following:

(1) Display/Edit a boost-based fuel map in PSI. I can see the Injector map that lets me choose the units (MAF voltage, various pressure settings)... Is one of those a PSI scale?

(2) Clamp the MAF (i.e. Airflow Output) voltage. How do I do this??! I see how I can clamp one of the Analog outputs but that's something different, isn't it?

On the Profec screen there is an E-Manage setup page that asks for Airflow Change and Engine CCs. What do I set those as?

I haven't started the car yet... Will the Injector map show me the "active" cell as I'm driving?

--Steve

 

1) There is no PSI table. YOu have to use one of the other pressure units of measure, and do a convetsion of something. I was thinking mmhg would be the easiest one to work with.

2) I swear..i am loosing my memory, not having my car for 9 weeks has done this to me. THere is a screen called..I think...fuel limiter or fuel cutoff/rpm cutoff or something of that nature. In it, you shoulds see a table with RPM on the top, and voltage or empty squares on the bottom. Just put a "5.0" across all the RPM values. That's it... you have successfully clamped voltage at 5.0V
3) Not sure what airflow change screen you are refering to. Dependign on your injector size, you'll need to scale the injectors in the parameters screen...towards the top. It will tell you to enter a start value (280cc) and an end valvue (440cc)...or whatever you have. If you already have the TS reflash, you probably wont need to scale the injectors.

 

Sweet. Thanks for the answers, everyone!

I did a few runs tonight at 6.35 psi and the MAF voltage got to 4.97 (and stayed there) by about 4900 rpms. No wonder then that I was maxing out the MAF too early at 8.5psi!!

It is going to be very nice to be able to add more fuel at higher boost
