Well I'm no webmaster, but I threw together a basic page detailing the installation of the e-manage in my Evo 8. It's not complete yet (I still need to install the ignition harness), but it's enough to get started with. The whole process went smoothly and should take a couple of hours max. If you have any questions not answered in the v-faq or I missed something, shoot me a pm. Here's the link:


updated e-manage install

 

Excellent write up. This will be very useful for me down the road.

Thanks for taking the time.

 

Solder??? Ive been told that soddering will create some resistance. Wouldnt this be a bad thing when working such sensitive parts of the car.

 

Ok.

 

The anount of solder used is pretty minimal, I wouldn't think additional resistance would be an issue. Perhaps an EE could chime in on this? I also wouldn't trust anything else to tie into those wires, ie. crimp-on connectors. Those connectors can come loose and do a very good job of chewing up the wires. That's something I don't want should I need to remove it (ALWAYS plan for the future).

 

Why get an EE when you can just get a voltage meter.

 

Then get a dvm and check it out. I'm not worried about it. The only issue with soldering these wires on would be the heat if you left the connectors plugged into the ECU (and that would be a stretch). If solder was such a bad thing, there would be a whole bunch of DSM's with s-AFC's soldered in that didn't work right. I've never heard or seen anyone have any problems with doing it that way. Generally, if you DON'T solder the connections, they go bad and lead to problems. Not the other way around. Besides the Greddy manual has several references to soldering in it.

 

I saw that in the manual. My only thing is that after having a recent conversation with my brother who went to a recent and Audi course on wiring, the corpoaration explicity stated that if you are soldering, you are doing something wrong. After checking the resistance he stated that its a state that can lead to bad results. It makes sense, if you wanted a certain voltage signal to the MAF, just a tad bit of resistance would give a false signal. I dont know have to see what happens.

I read on how Evo 7 were going through problems with the coils.

 

99,
How do you like the e-Manage? Any issues? Comments?
Thanks!

 

I haven't done a lot with it yet. I'm going to the track tomorrow night so I'll be able to play with it a bit then. I'm trying to tune a bit before the Shootout. Driveability is the same as stock - it's like it's not even there. My ignition harness will be here in a couple of days so I'll be able to finish my write-up.

 

Soldering Increases resistance?? Actually crimp connectors, twist connectors, splices, etc can be more problematic.. Soldering would actually have less resistance than any other fastening method because there is more surface area used to conduct electricity.. YES, there is slightly more resistance than just copper wire.. but its MUCH less of a problem than most other fastening methods.

Someone else mentioned something which is extremely true, and has happened to all of us at one time or another.. just twisting or crimping a connection will eventually come apart.. also, exposed metals can oxidize over time, and that will decrease the conductivity in an exposed wiring joint that has not been soldered or sealed in some way.

Use your judgement, you can use a wiring harness extension and solder all of your connections, in turn it can be easily removed in the future..

 

Oh.. and if your concerned about the resistence of solder, you can always use solder with a gold or silver content which has less resistence than "Tin"

 

solder is the way to go, make me a bit nervous tho

 

hey!! awsome instructions, ive been looking for this for awhile now. do you have the pin locations for the other optional harness that i have.. i think its the injector harness. im ganna install it on my extention harness thanks to Z1. how does ithe emanage work with the car? do you feel noticable inprovments?

 

The injector harness ties in to pins 1,2,14, and 15 (injectors 1,2,3,4 respectively).

As far as the butt-dyno is concerned it feels a little faster, but I'm also leaning out slowly so I can watch o2's and timing, etc. Once I get the ignition harness installed I should be able to notice some larger gains.
