2.2

I was looking over an MR2 board and someone there had found this cool little device:

It looks like one of the guys on there picked one up and it is working ok for him. This might be a bit of an alternative to other more expensive products and have more features.

Here is a link to some guys who are using it already:

Aww, they give you source code for the unit, too. That warms my heart. It looks like a solid unit. I wouldn't compare it to the EMS, but for the money it's a great fuggin deal.

My only problem is that there are a number of SMT components used... surface mount technology is a huge PITA. I can't deal with that stuff unless I have solder paste and a soldering station that blows hot air (for use with solder paste and SMT). My hands are just not steady enough.

True that, SMT isn't easy.

From what people on the MR2 board I found it on are saying, it is comparable to the Haltek E6k and the Tec3 that they are using. I must say, for that price I am almost tempted to go through the frustration and annoyance of soldering and stuff.

Since they tell you that you can do it with a regular soldering iron it's probably not the tiny tiny SMT stuffs. I've had some luck with using a microscopic dot of slow setting epoxy or superglue to hold the part in place, then coming back an hour or so later to solder. That makes repositioning parts a problem sometimes, but they can be popped off if you're gentle.

Keep in mind my hands shake a lot, and just about anybody on the planet can be better with SMT and a regular soldering iron than I can.

hmm...sounds like a fun project

The reviews on the MR2 board sound great. If nothing changes my mind, I'll be ordering one next week.

Sweet, tell us how it goes. I want to turbo my GS-R but the price of good engine management and tuning scares me away sometimes. Something cheap that I can actually build myself and has tons of features would be cool.

Also, I wouldn't have to mod my ECU, so I can just throw it back in when I want to sell the car.

I don't know when I'd be able to update with it running or not. This will be for my CRX roadrace car, which isn't planned to be running until next summer.

I'm currently running a Haltech E6k on my Prelude, I guess I can unplug it and plug in this thing to test it out.

Looking at the fuel maps, on boost load points are limited. A single point for 10psi, 20psi, and 30psi each.

The software looks rather rough, but it's very capable and $330.00 is a bargain. The outputs are it's best feature. The only thing I would like is more inputs, flat shift, trims, datalog sensors like EGT. From reading the MR2 forum, people with limited soldering experience are putting it together with no problems, so unless something convinces me not to get it, I'll probably order it Friday.

2.2

I am interested to know more about how these computers work and how to tune them...well any computer for that matter because my knowledge of EMS's and how they work is very limited.

I could see this as a good place to learn.

Ask the maker to set up the software so you can assign your pressure points for greater boost resolution. They'd probably be very amenable, small companies usually are.

did anyone see if this thing can be used to control boost?

DirtyLude

It has a boost solenoid control feature. I obviously have no idea how well it works.

check out ghettodyne.com.... he does if for crx's etc.
