Great job Chris. I am thinking about doing this to. But adding this with my vortech install.

 

i have to solder? darn. looks like i'll have to pick up a gun and start practicing. how hard is it? it just seems liek u put thetwo wires together and then u use lead or whatever and melt it on top..?

 

lol...umm...I guess that's it in principle....a little more involved than that though...I'd suggest some practice

Well, as Wes said, you have the basic principle down, but you need to really practice to get a good technique. Here's a picture from the GReddy eManage manual that shows how they recommend the wiring be soldered together. The important thing to note is that you don't actually cut the wires in the ECU harness (well, the MAF sensor wire is cut, that is the exception). You just have to remove the wire cover and then twist the eManage wire around it, then solder it well and wrap in electrical tape.

 

This tool looks pretty cool for soldering

Hmmm... that does look pretty interesting. I have seen the crimping tool that you get free before and actually thought about getting one because it would have made wiring up the eManage A LOT easier, but that "Cold Heat" soldering gun looks a little iffy. The heat might be a bix excessive for most purposes, but for $19.95 it might be worth a shot?

Well, I seem to have run into a snag with my eManage setup. Here's a link to the thread with the problem I am having because I noticed a few similar issues on there.

That was a good read, if any of u N/A owners looking for a new greddy emanage i have one for sale pm me or find my thread in the for sale section. Hope all goes well seems like it's a good idea.

 

That's the old resistance soldering idea with a new marketing twist. I wouldn't use it on any wires connected to sensitive electronics (like your ECU). What you want is a 25 watt ESD safe temperature controlled pencil iron from Weller, Ungar, Metcal, etc.

I use the Weller WTCP solder station for this sort of work.

 

I use a 15 Watt with .020 gauge solder. Works like a champ and is safer for sensitive electronics due to lower heat.


As for the problem that I ran into with the eManage, it has been resolved. With the 1.39 Firmware update, the rotary switches need to be set to 7-0-1 rather than 7-0-B. Also, version 1.11 of the Support tool should no longer be used with the firmware update. Version 1.13 should now be used instead.

Yesterday I also decided to hook up the Throttle Position sensor to the eManage. It is not mentioned anywhere in the instructions so I did a little searching around in the Service Manual and founf that there are 2 sensors. The one that should be used is at pin 50 of the ECU wiring harness. I hooked it up to the gray wire on the eManage harness and it works perfectly. It's not really needed, but it's just adds a bit more functionality and also is cool for the data logging because you can see how much throttle you are inputting at any given point on the graph.

sweet, thanx for the update & info chris......will be handy when i get my emanage.......

I didnt see anything on the manual but would it be possible to change the rev limiter with the GReddy or any other piggy back system?

 

oops...

 

No. Piggy-back units (like the eManage and S-AFC) don't change anything about the ECU itself, it just intercepts and changes certain signals to increase/decrease airflow and or fuel enrichment. The only feature that the eManage does other than that is allow you to change the VTEC shift point, but since we aren't driving honda's, it's useless to us. If you want the rev limiter changed, contact TechnoSquare.

 

could this system work on conjunction with the technosquare reflash? I'm just starting to scratch the surface of electronic modding, so I am really clueless.

 

Chris...nice work. Sorry, I havent been following this thread until now. Looks like everything is coming along really well. Congrats!

The difference between an S-AFC and the eManage is that the SAFC alters MAF voltage signals to trick the ECU into seeing more airflow, which the ECU sees and adds more fuel.

The eManage doesnt alter the MAF signal to enrich fuel, as long as you use the injector harness, which Chriss did. The emanage has drivers for the injectors, and actually adds injector pulse width on top of the stock ECU signal. Excessive MAF conditioning a la AFC can result in unwanted timing advance...not good.

The eManage is the next best thing to a stand alone...in my opinion, and works equally well with N/A and F/I applications.

And yes, you can use it on conjunction with a TS reflash. Some people prefer to get a reflash, and then do the fine-tuning with the eManage.

Hth,

Sharif

 

I'm contemplating adding larger injectors and pulley for the ATI and was considering the AFC for fuel mgmt on top of a TS reflash....I think I may lean toward the E-manage and a better fuel system and ditch the Aeromotive all together.

I think Max has already done this....but I think he's just using TS tho.

The benefit of getting a TS flash first, then using an eManage is that you get all the additional updates like higher redline, no rev limiter, 100% Throttle fix, etc PLUS it will alter the maps so that they are more suited to the mods installed on your car. Then you can "fine tune" with the eManage rather than doing a lot of tuning (which it looks like I am going to have to do). The other thing you will need to have to tune your car with any piggy-back unit is a Wideband O2 gauge. Preferably one that has data logging capabilities so that you can go back and really get specific on the A/F ratios. I am leaning towards the Dynojet Wideband Commander, but the AEM gauge would be good too. I have recently found out about a few others, but you are looking at about $350+ minumum. If there is anything cheaper that does a good job, I would love to hear about it

-Chris

 

I have the Dynojet Wideband Commander, just don't have it installed yet. I got it on a Group buy with some of my Lightning buddies(also own a high HP L) I plan on installing a few things once I figure out the oil consuimption issues

you dont have to solder an safc in. we simply crimped them with the connectors. still holding fine 6 months later.
