(EDIT: For solution to this problem, see posts below!)

This would seem like the most basic hook-up yet I fail to see how it is possible. Isn't there an extra analog input into the emanage? How do I tap this?

FYI: I just need a analog input that will accept voltage in the range of 0-5 or so. And this is NOT for the E-01. I already got that covered.

Again, I am left fending for myself.

So I bought this from http://www.mohdparts.com/emanage/ . It is part # 15900912 . Unfortunatly, it looks like I lose my boost signal into the emanage. Not sure what this means. Going to go down and look at the emanage and see what I have connected


This harness is used to feed the air/fuel signal from your wideband brain to the e-manage.
Will work with e-manage upgrade v1.25/1.47 or 1.25a/1.48

E-manage Air/Fuel meter Input Harness #15900912
Its a harness for inputting the A/F meter signal into e-manage.
Simultaneous use with a pressure sensor becomes improper.
Simultaneous use with a Multi Switching System recognition adapter becomes improper.
Corresponds to v1.40+ of e-manage firmware.

Well that is stupid. I have to disconnect the "COM to BOOST" harness from the E-01 to the emanage. All that will do is releave me of my engine once I go into boost. What is the point of the AFR harness? Maps via AFR? While that sounds great, I am not so excited to be a guinea pig. Any thoughts?

So this is a screen shot of the "Data Input Setup" for datalogging within the Greddy Support Tool


Note that I have highlighted some area that I would like to know more about.

1) THe area in brackest is the "boost selections" I would like to know if the "relative" pressures are just conversions of the "greddy sensor." If that is the case, then subing out the boost for afr nixes your ability to datalog boost. I cant imagine anything dumberer.

2) The circled area shows that there IS some sort of "AUX input" What and where is this mythical beast?

3) Just FYI, I boxed the area showing that there is A/F functionality somewhat programmed into our emanage blue/gold boxes.


Please note that the selections are grayed out because there was no emanage or map connected to the computer at the time is screenshot it. These are active check boxes when the computer is connected.

The only person on this forum who's familiar enough with the emanage to give you reliable direction is probably Jeff. You might want to try to PM him.

There are also many emanage specific forums online, such as http://www.emanageforums.com/forums/.
You could try posting your question there.

The limits of reconfiguring the emanage have been done my MD. No one else has really strayed from Greddy's plug and play configuration.

But I can say, I definitely wouldn't swap your boost sensor for that adaptor you purchased.

Thanks Ryan. PMed jeff.

The emanage forum was a find. For some reason that did not show up in yahoo searches. Also interesting, there is a yahoo emanage group but I havent figured that one yet.

I am now confident that you can read A/F into the support tool buy usurping either a secondary airflow meter or some other analog line in. See the following post.

Unfortunately, while I can download the program discussed in that post, I cant get it to run. Yet.

Got your PM, but I'll respond here for the benefit of those who might seek the same info.

Your primary AFM input isn't doing anything, why not use that?

On my setup, I am tweaking the AFM input/output to ameliorate the over-rich situation that arises from the "lost" air that goes out the BOV at part throttle/mid load.
However, as it is shipped or even if you are using MadDog's MAP, the AFM table is unused.
If all you want to do is log the signal, that'll do.

Now, if you want to do auto-tune, you will need to use the hack software from that guy in Taiwan. I never bothered to try to get it to work.

Yahoo E-Manage group is here:

Great! Thank you.

So this is the white wire in the harness #1? Shown here for instance. Please confirm.
http://mohdparts.com/emanage/manuals...-manage_10.JPG

A simple cut and splice, I assume. This is perfect.

I would hate to hijack my own thread, but I suspected the same thing was occuring in my car at a steady 5000rpm when my AFRs would decend to 10.5 or less and the car would stumble. I was going to tighten down the BOV, but maybe I should at least try this. Have you described this on your website or here? a ref would be appretiated.

I have the hack, though the program is not working yet. Not sure why. I tryed it on my desktop and nothing happened. I tryed it on the tuning laptop, but I needed to update the .NET environment from MS. That took all night and I will try it now. Without it, the program will not initialize.

It seemed to me from discussions of this program that you needed this hack PERIOD to datalog AFR. This is not true? (I realize the afm hack will datalog, but it will just be in V. Maybe they were refering to the ability of the hack to convert to AFR. That seems a little simplistic and hardly worth the effort. It makes more sence that the hack does more complicated things.)

Thanks.

In addition to the above questions, I am curious if you got the software from the guy in taiwan to work. For some reason, it will initialize, but I see nothing. Basically, I double click and ... nothing. Any hints.

Oh, and whats up with this?


Hung over indeed.

I will remove this at your request. I just thought is was ******* hi-larious. You should use it as your avatar.

Ok. I tried the possibility of datalogging on the #1 MAF input. First I started the car and connected the laptop and started the emanage support tool. While monitoring the MAF sensor voltage, I clipped the white wire on the emanage harness. Voltage dropped to zero. Bingo.

The car did stutter at the time that I clipped it, which made me curious. I thought that the MAF into the emanage was unused? I went back around to the driver side to shut the car off and I noticed a MIL and my idiot light showing the car sliding around on the road was illuminated. I pulled the codes and I had a missfire and a P0100 or P0101 or something like that. I desided to just erase them and see if they reappeared. AS SOON AS I ERASED THEM MY CAR STALLED!!!!!!!

When I tried to restart, no go. I stripped the MAF wires and reconnected them and the car starts fine (though I have not driven it.) So I am back to square one.

So apparently, the MAF signal output must go back to the PCM and be read there. I suppose I could just cross the MAF in to the MAF out. Will this work???

Ok, that worked. Just spliced the green and white wires together before the harness and then spliced a analog out from the LC-1 to the white wire into the emanage. Going for a drive

Yeah, the MAF is hooked up in the Greddy wiring, it just isn't mapped. Sorry I didn't point that out.
a scope-meter is your friend.

Well, that did it. Just cut the white and green wire on the harness #1 into the emanage, and tie them together on the pcm side. Then attach an analog out put from a WBO2 onto the white wire into the emanage. You could program the voltage on the WB output to make immediate recognition of the AFR easy. It is up to you. 0.5 as 10:1 and 3.5 for 20:1 with stoich as 1.9 is recommended (mazdamanic.com).

Now you are ready to run the support tool and log your AFR under the MAF voltage in. For the attached graph I exported the data using an excel macro (I got it here) and graphed the data on Origin (it is a great program, and it is only $899. Get it here)

The attached graph is just a crappy demo run. Not even full throttle. Just enough to show that it worked. Typical boost is about 6.5-7.0 in third WOT, 8.5 in fifth WOT.
