Ok, I'm in the process of taking out my vortech kit, and going turbo. In doing so I am going to keep the split sec timing and have that remapped. I am doing this because it is much more accurate in controling timing than the emanage.

I will be using the emanage in conjunction with an fmu and stock injectors for fuel management. This is the same setup I currently have with the vortech install.

I also have the emanage wired in using a wire harness from frog.

I have the split sec timing wired into the main wiring harness. I didn't know about frog in 03, so I had to painfully cut my main wire harness and figure out WTF vortech wanted me to do with those aweful instructions!

When I access the emanage tool, and log my runs, I can see the map reading. The level never goes into boost. I am assuming this is due to the cap put on by the split sec timing box. So I have the car dialed in for WOT (or when the map is at it's max), which in all honesty is fine with me. I have an 11.7 to 12.7 af across the board in wot. (I did the tune so it is not as percise as a professional, but I am happy with the results and they are much better than before I put in the emanage).

However with the turbo I want to install the eo1 boost controller. I want to control boost creep, spike, and have 8 psi for race days, and drop it to 4 or 5 for street driving. Anyway, the emanage currently will not be able to read the boost level. With the current set up, I programmed the emanage to access the extra injection cycle slightly before the map caps out to add fuel.

In a rather verbose way, my questions are:
1. Does anyone know how the to allow the emanage to see boost but not pass it on to the ecu?
2. there is a boost sensor for the emanage. Is this is a different sensor that will allow a map with a "missing link" or other caped map signal to send the actual reading directly to the emanage and bypass the factory harness, or is this just a replacement map that can see higher and more accurate boost levels?
3. In regards to the emanage boost controller, do you need to have the greddy pressure sensor for the boost controller to work?

Does anyone have any idea?

Lastly, just as a side note, to avoid the ecu from "correcting" my tune, I have had the backup fuse out for several months and I have not had any issues. However I am wondering if there are any side effects to this technique.

Thank you for your time reading this.

 

For the Emanage to see boost from the MAP sensor, the Vortech MAP (the small black box) clamp needs to be wired after the Emanage, before the PCM . It sounds like you've got it before the E-manage on the Stock harness.

I removed the MAP clamp and used the Emanage's Boost cut feature to hide boost from the Stock PCM.

 

that is correct. The emanage is after the vortech box

I honestly did not have a clue how to wire up the emanage (I would have to brush up on my japanese reading skills)) which is why I went with the frog harness.

Could I bypass the split sec timing box in regards to map readings? Does it need a map reading, or does it just clamp it? Because according to greddy, the emanage can also be used as a voltage clamp.

If I am looking at this the right way, I figure if I cut the wire on the frog harness that has the white map sensor reading, and cut the map sensor reading on the vortech box, then put the wire from the emanage to that wire before the vortech box. I would get my map in readings. Then I would have to cut the wire harness with the map out so the circute would include the ecu and the emange, not the vortech box.?.?

-OR-

I just got off the phone with greddy. With the profec e01 boost controller, I'll need the included pressure sensor. the pressure sensor will use a vaccuum line and harness to link into the emanage. So this will send accurate boost levels to the emanage.

So I could use the current map levels for vafc tune before boost (like I do now), and then pressure vs rpm with the emanage sensor for boost tune.

Does any of this sound logical? Do you foresee any problems in my logic?

Thanks

 

You can use the Greddy MAP sensor and harness for the emanage to read boost. I have one for sale. If you are interested, PM me.

 

There are 2 boxes used by Vortech. One is the Timing controller, the other is a MAP clamp. To remove the MAP clamp, just re-splice the OEM wires you cut to install it. I believe the 2 wire colors on the Map clamp are white and blue.

The Timing controller has it's own built in MAP sensor, it doesn't use a input from the stock MAP sensor.

If it where mine, I'd remove the Vortech Map clamp and use the Emanage as the MAP clamp. You can then tune by the Stock MAP sensor, or use the Greddy pressure sensor.

 

It's been a couple years since I installed the kit... time to get out the instructions, but I only remeber one electronic box...

so after longisland melts from this blizzard, I'll have to roll the car out and take a peek!

Thank you for the information in advance.
