I'm extracting this conversation out of another post...

Basically, I'm looking for a technical explanation of why the unichip is better than the emanage at controlling the ecu.

Looking for "Hows" here if possible.

If both units modify a signal, how does the unichip prevent the ecu from possibly learning.

On the same note, how will the unichip prevent the maps from leaning out when summer comes around where as the emanage (not proven yet from what I know) will have to be retuned possibly.

I'm just trying to get the facts of each unit - since the unichip site doesn't explain HOW it does what it does. no wiring diagram, etc.

Post em!

 

I think its because the Emanage alters the signal going into the ECU and thats where you come into the learning problem while the Unichip alters the signal going out of the ECU therefore not running into an issue of the ECU trying to re adjust for the boost. Plus the good thing about the Unichip is that it has two different maps for your car; one for basically street and another for the track. Its definitely sick and Im gonna end up grabbing one. You are right though about the weather and having to retune the car. Especially if you have drastic weather changes wich I would say you do comeing from where you are. What you could do is have a summer/winter setup instead of street/track settings. Plus as you add things, the Unichip can be reflashed to support the new mods.

 

Ahh, I did not realize it changes the output of the ecu. I have to take some time and think about that and see if I can think of any "weird" scenarios.

 

It's all in the tuning of it. You can tune an e-manage not to relearn or use the stock ecu to relearn in a good way. It's all in the tuning and monitoring. You have to understand what the ecu is doing and respond accordingly showing it what it wants.

 

yea, thats true, just dont let some joe schmoe from down the street try to tune it for you if you go with Emanage lol. They could do a lot of damage to your car, hence that kid with the Scionspeed stage 2 turbo that blew his **** up cause of a horribly bad tune. The kit comes with the pretuned Emanage for you right?? I would pull a lil more timing if you can for the winter time, but thats just a thought.

 

Thats exactly the difference. Since the unichip is POST ecu, the computer doesnt see it and therefore doesnt know its there. THe unichip is programmed very similar to that of the emanage but since it allows the ecu to compensate automatically for the ever changing weather conditions, you dont have the issues you see with the tune changing in different times of the year.

The Emanage Ultimate has the same ability to switch between multiple maps. The blue box does not.

Paul, Im confused a little by one of your comments.

"You can tune an e-manage not to relearn "

In my experience, the emanage doesn't do any sort of learning. It manipulates the feedback it gets from the engine's sensors and feeds them into the ecu. It doesnt change on its own. Now, I know the ultimate has an auto-tune feature that can be used if you know what you are doing, but it doesn't constantly change.

Now I do agree that you can use datalogs and 02 feedback to change your tune to adapt to what the ecu likes. Basically putting it within the perimeters the ecu is looking for so that it doesn't constantly fight itself. But as far as I know, the Emanage has no "learning" abilities.

I've wondered from the beginning, but never asked, if I should upgrade to the ultimate or not. I'll have to really dig around and see what the Dezod folks suggest also since a unichip is really not an option at this point.

In the meantime, I have no issues with monitoring and swapping maps if needed.

Thanks for the info guys...

 

this is a good discussion as i too was debating between the unichip and the emanage ultimate, i dont see a difference in the two except for the ultimate can adjusst rev limit, does the unichip have these capabilities as well?

TIA

 

What everyone should keep in mind....

Right now Greddy is having a few firmware issues with the emanage ultimate. The blue box seems to work flawlessly, but the ultimate is having some timing interface issues. The box doesn't allow for timing retard on cold start and the car simply wont start when its cold. I've contacted them directly about this matter and we are currently working on a good solution. If you don't wire in the timing harness and you calibrate the box correctly, then it seems to work fine. I know some people had some issues with the injector correction as well, but it has been hit or miss. Just a little food for thought.

is it possible to have toyota install the unichip (and also the weapon r engine damper) and how do u change between the 2 settings?... i might have saw u before i went to the scion dealer in smithtown a few times i test drove 1 before itll soon be my next car

 

You can ask but I doubt they would. Its like asking them to install a turbo in the tC some dealers may do it while others wont all you gotta do is ask. If they do install it they will honor a warrenty on the labor but not on the product and may make you sign some form of a waiver about the warrenty.

 

This topic has been on my mind for some time now as well. For a future t/c or s/c owner, which woul dbe the better tool. All I've ever heard about was the Emanage/Emanage Ultimate but the Unichip seems to be peaking my interest. Any pros or cons between the two and would I use one over the other based on specific turbo applications? If so, in what scenarios?

 

yes iam very curious too.

 

So with the mods I have.. would it even be worth getting either of the two? I guess I dont have a good understanding of what this actually does..

 

Where can you get the unichip? websites please!

 

If you go to their website which i think is unichipus.com or something like that and type in your location and they will show you some authorized dealers.
