I like the EMB.... honestly, when I first installed it, I was scared about it. I like the control to do the timing/fuel.... but I was worried I was gonna screw it up.
But after having it installed for a year, I'm very happy with the results. I have control over the timing, and the fuel... and I can datalog, change whenever I want. The autotune option from olderguy, makes the maps a snap.... once you get your head around it.
It was a great first step. I would say, I wouldn't be as afraid of something like a link, SDS, MS, etc... now. I understand the concepts, etc....
However, I would also say, there are limitations.... The data cable is one, you have to make one, or get a real one. So if you are getting an EMB get it with the cable. I didn't get one, but I also paid 200 cdn for it. Harnesses are good.... I'm to the point, if I was to start with a stock car, stock harness, I'd leave it that way. Also, there's the autotune. Add-on to the EM-B, but worth it. Simpiflies the maps, and helps with the tuning, so anybody can do it.
Finally, I wouldn't do any of this again, without a WB. I know the prices have dropped significatly since I've been boosted, however, I really like the idea of having something to make sure the tune, the stock O2 is doing what it says. Would I look at it, every day.... no.... but it does make it much safer, etc for when you are tuning, no matter what you are using. Especially, since things like the www.14point7.com
(JAW) is so cheap... you can put it toget for 100->150 bucks CDN. Which is nothin'.
I did a thread on the BRP forum, when I did the initial install, to help people over there understand what it was that I was doing, and why, outcomes, etc.... Hanging out here, I've learned a lot too.... but it was just something I wanted to have to help people searching there.... Might be worth the read.... <G>
