Emanage advice

[Fluke]

After getting the emanage repaired :mad: ,evrythink now works as it should. The emanage has been set up using a base map from a similar set up to mine and I have now fitted it along with an O2 clamp. I have the actuator wired open on the supercharger and but still have the MSD fitted. I have a 150mm crank overlay and slightly larger Mk2.5 injectors fitted. I have a knock sensor on order and it should be here soon. once the knock sensor arrives, will I be okay to remove the MSD and start tuning? Is there anything else I need to look at?


I have a Uego Wideband sensor and guage fitted, but as I have a 3 bar map sensor I'm not sure yet how to log AfR's, can anyone advise?

[Accord2nrz]

I think the majority of us dont actually log the afr's we just keep an eye on them when tuning and do our best to correlate the time periods.

[Dzaster]

I've done it two ways.

1) Emanagetools 3rd party software, downloadable via our downloads section. This option requires you to wire your wideband through the Emanage.


2) Angled a video camera to capture AFR and RPM while also datalogging on the standard Greddy software. You can then review both and reference AFR and Greddy datalog based on RPM.


I've used both methods. I did the camera for a while, but I managed to use the Emanagetools softaware nearing the last few days of tuning.

[Accord2nrz]

Which do you prefer dzaster?

[Dzaster]

Just for datalogging AFR vs RPM vs Boost I like the Emanagetools 3rd party software. However, it doesn't datalog a bunch of the other parameters that the Greddy Support Tool software does--i.e. injector duty cycle, adjustments made to ignition timing, and VTEC control.

The other problem is you cannot run both Suppor Tool software and Emangetools software at the same time. Its either one or the other only.


So the video option allows you to record AFR and run the Greddy Support Tool software, thus allowing you to get the full report.

[Fluke]

Its been sugested that I use the TPS wire to log AFR's? Do you see a problem going down that route?

[Fluke]

Just taken it for its first run and I noticed that it seems to bog down a lot. It seems to be over fuelling as I am seeing 10 on the AEM Wideband gauge at about 2.5K revs.

[Dzaster]

Do you have any datalogs and would you wanna upload them with your current map used when that datalog was taken? You wanna upload them and put up a link here, I'll take a look at it.

You may be right about it running rich.

You can use the TPS to datalog AFR's but not using the Greddy Support Tool software. Also, unless you currently don't have your TPS wired into the Emanage you will be sacrificing quite a bit of fuctionality from the Emanage.

[Fluke]

The only thing I dont have wired into the Emanage is the air sensor (white and green wire), but I was told that tuning using the Greddy map sensor would give better results.

I havent had the chance to data log anything yet but here are a few screen shots of the way its currently set up.

Do the settings I am using look okay?

I notice when I change my injector sizes, that when I restart the car and check emanage the injector boxes are blank is this normal?

[Fluke]

I had an attempt at using Emanage tools to see how effective it is at logging and was surprised at how easy it is to use. Here are a couple of screen shots showing the results.

I dont have the MAF wired up and have wired up the AEM wideband to the secondary air flow sensor wire on the Emanage.

[Fluke]

I have tried connecting the MAF and my car sont start. I changed the settings from 3-A-3 to 3-A-C and it will start and run, but the AFR's go very rich and it wont start up for a second time. 3-A-0 is also a no go. Any idea what might be wrong?

[Fluke]

Took my car out for a couple of runs to try my hand at data logging and notice that when ever I went into boost my car was going very lean. I checked my logs when I got back and found that no boost is being shown?

[Dzaster]

K in the emanagetools software you have to make sure that you input the correct values to which the software is to convert voltage to AFR. You should have a look at your manual to see if it tells you what the two values should be.

The first time I used emanagetools I missed that and for the time I used it I thought i had something wired wrong or the software just was inaccurate. However, months down the road I decided to try it again and this time I found that the default software values were incorrect for my wideband.

I suggest you check your manual before assuming its lean. Does it say its lean on your AFR gauge?

[Fluke]

Yes gauge is showing lean.

[Dzaster]

Do you have a garage setup stating your setup of your car? Kinda have no details. I'm not savvy with car's engine codes and what not so pretty much, need it in specifics--for now cc of injectors(stock and upgrade size if applicable).

[Fluke]

It a UK Mazda MX5 (1800cc) fitted with an M45 supercharger, crank overlay, air/water charge cooler and 265cc injectors. The stock injectors are 254cc, The engine uses a coil pack (wasted spark) and has a hotwire air meter, earlier 1600cc models used a flapper air meter.

[Fluke]

I had a look at the Greddy sensor today. It turned out that it was faulty so I used my mates spare, here are the results of a quick run that I did.

How do the AFR's Look?

[Dzaster]

Now that looks pretty darn good.

Except, your injectors seem a little small and you might datalog with the Greddy Support Tool as well so you can check those duty cycles on your injectors. 80-85 tops. More than that and your injector is nearly staying open and at the least you'll mess up an injector.

[Fluke]

I am not sure how to enlarge the graph to make it easier to read, but this is what I have.

Gonna try and explain how to expand a particular area of the map.

1. Highlight the specific area to be expanded. To do this you click the one side of the red arrow, hold the click as if dragging and sweep mouse to the right or left. The area will become highlighted/shaded.

2. Click the button I've circled and pointed out in blue. That will stretch the highlighted areas to the width of the graph window.

3. To plot a specific part of the map you simply click on the desired point of the graph and a black marker line, similar to the green one I have there, will display the results of that plot to the right.

[Fluke]

Thanks.:) is this better?

http://premium1.uploadit.org/yan816//injector-cycle.jpg

I still cant get the MAF connected, the white wire on the emanage is supposed to go to the sensor and the green to the ecu, all the jumpers are set at the factory settings. Here is the air flow wiring diagram with the ECU pin outs.

http://premium1.uploadit.org/yan816//MAF.jpg

As you can see there are only really 2 ECU pin outs to choose from, 3K is the air temp and 3B is where I need to connect. How much functionality am I losing by not being able to use the MAF?

[Fluke]

Is there anyway I could test the emanage to see if it is recieving a signal?

[Dzaster]

Yeah for testing it would show you signal on the right as "Airflow Meter Input" and an output as well. I have only installed on my car which is MAP sensor. Have you tried doing a search in here for some MAF discussion? Just to get some ideas of what guys have talked about. Seems like a lot of talk about MAF giving problems and needing something special done to work right--or just plain old user error. lol



As for that you have to find/click on the highest point of boost on your graph and check the total injector dudty cycle on the right. It that image you are at 2k RPM and 12% duty cycle. Click on the highest and see what your duty cycle is.

[Fluke]

Thanks. I was thinking of taking a wire from the TPS signalon the ECU and running it to the MAF input on the emanage, just to see if a signal is being recorded on Emanage tools.

[Fluke]

Anyone?

[Dzaster]

I believe as long as its 5v or below you should be good.

[Accord2nrz]

+1 as a matter of fact you could pick any 5V source and it'd work.

[Fluke]

I still cant connect my emanage to the MAF wiring on my ECU. I have even tried fitting the 1K resistor just in case that was the issue and I still cant get my car to start with the MAF plugged into the emanage. I have even tried a new Emanage unit just in case mine was at fault.

[maxgtr2000]

In the parameter settings in the pull down window at the top where it says maf type, do you have the correct setting selected there? Your rotary switches can be right but double check the maf type since you tried and got the same results on a different unit.

[Fluke]

If I have a Mk1 Mazda MX5 1.8 (NA) using a hotwire MAF. What should I be seeing in the parameter window?

Not sure because I'm not familiar with those cars at all but I found this thread, I hope it helps.

[Fluke]

Today, I went over my wiring again and rechecked the jumper settings on the Emanage and I still cant find the problem. I managed to get it started with the MAF connected, but it was running very rich and as soon as I pressed the accelerator the car stalled and would'nt start untill untill I took the emange out of the loop by reconnecting the MAF/ECU wiring.

This is really starting to bug me as everything works perfectly if I just use the MAP and ignore the MAF altogether.
