Installed my DSM AFC last night

Well after about alittle over a month the AFC arrived on my doorstep this week. I finally couldn't stand the wait anymore so I decided to install it last night. Let me say first, thanks to Casopolis for the wiring diagram, it made the install easier to understand. And secondly, thanks to DSMConvert for making an awesome product, I couldn't be happier.

The install was pretty easy for the most part. After taking off the plastic side pieces and pulling the carpet back on the passenger side floor, I removed the metal plate that the ECU was hooked to. (note: be careful when doing this, the edges of the plate are very sharp, I cut my finger on it). Oh, and in case anyone is doing this in the future, the bolts that hold it on are 10mm size. I used a small ratchet with an extension. The ECU was a large sqare box with a wiring harness going into it. It is held on by one 10mm bolt. I recommend getting one of those spring loaded wire strippers. It was a lot easier to use because the wires were so small. I chose to solder my wire connections. I got some vacuum tubing and a T-fitting from Pepboys and used the intake mani vacuum source. And finally mounted the AFC in the glove box. I drilled two small holes to run the wires out the bottom of the glove box.

As for the performance improvement. I took it for a drive after I was done. I had no idling issues, no CEL's, car worked perfectly. All hesitation is gone, and power delivery is much stronger and smoother throughout the revband. It is like a whole new car. The butt dyno tells me there were some power gains. I will hopefully be getting a dyno done this month to send back to DSM for even more power tweaking. Overall, this is by far the best mod I have done to date for the car. For the improvements it made it was well worth the price and the wait. I highly recomend this to anyone who needs an EMS, but doesn't want to go the stand alone route. This is definetly an awesome product. Sign up now to get one.
 
I'm satisfied with mine too. Just wondering though, what boost are you running now? Which vac line are you tapping? I may relocate mine to the brake booster after I get the vacuum block setup.
 
I'm running like 9.5psi, sometimes it spikes slightly past 10. I taped the small black vacuum hose on the intake mani. Its the same spot I have my boost gauge. I just got another T-fitting to go next to the boost gauge one. I thought about going with the brake booster line also. I've heard that suggested on this site. I just wasn't 100% sure on where exactly it was and where I should tap into it.
 
how long a difficult was the install, I'm getting mine from freshorange. I'm going on 9-10psi also... Basically all bolt on's in the front end and perrin exhaust.

The install isn't too bad at all, just time consuming if it's your first time removing the ecu. I suggest downloading/printing peepsalot's ecu diagram to make the install smoother and also to use some 3m scotch lock connectors. The connectors that were provided were made for a different app. Also finally use gloves during the removal of the ecu.

Most of the people on the board, ran the vac line thru the driver's side gromit. Get a 1/8 to 3/16th connector in order to extend the vacuum line. Also make sure you have a t fitting for the 3/16th line around. Lastly, some long/short wire ties are needed.

From start to finish it took me about 1:30hrs and that included me soldering wires. As long as you have all the supplies and know where you are going to tap the vacuum source, I'd say 2 hrs max. I definetly recommend the diagram, it helps in locating the wires to tap. Otherwise, the wires are numbered on the ecu harness and you can count them.
 
tenacious, can you pull the maps off of yours and post?

i have the AFC installed in my car and it started running like crap, so i checked the maps and they were not the maps that i originaly put on the AFC.

i just want to see what maps yours is running, mine had the supermap on there untill it reset some how.

I would try, but I don't have a laptop. I know that you can download the supermap and the fmic maps at www.airflowlogistics.com

I wouldnt mind seeing some pics of where you mounted it either.


Inside the glove box. I just drilled two small holes to run the wires through.

Just searched... Where can I find peep's diagram
 
tyrant...both maps are available on our website...if your maps spontaneously disappear again let me know....def not something that the afc should be doing...
 
DSM, ya thats what i thought too, its been ok since i reflashed the supermap, i just thoguht it was strange since this one is the second one ive had, the first was DOA.


but i will let you know if it happens agian.
