Lotta the escort guys use it. It's pretty good for what it is, but it's more work programming it than the xcal and, without lots of time (and some money) can't do everything the xcal can do. It's really better to use it on obd1 or older cars that have no other reasonably priced tuning option. The xcal2 is reasonably priced and is what I would go with.

I've used it on an old BMW, its very nice if you want to learn ALOT about tuning, but for the cost of the xcal I would rather get that if you are looking at tuning your contour...
With the Megasquirt you have to do a lot of custom wiring and figure out how to integrate the megasquirt with the rest of the ODBII functions required to make the car run

The xcal can be had for 300-400$ The PRP costs $300 by itself. If you just want a tune for your car get the xcal2. If you wanna do serious tuning, and homework, then get them both from brenspeed.com (brent white)

Nope, only your car unless you buy different codes. The $$ add up when you do that!

I currently use it on my Mustang, and I love it.

Tuning it really is not difficult, you first go throught and tell it what it will be running, (# of cyl., # of injectors, spark type, O2 type), then you set up base VE (volumetric efficiency), AFR (air fuel ratio), Spark, Idle, Acceleration tables, and finally you begin fine tuning everything, it seems like a lot, until you start working with it, then it feels like nothing.

The software is all open-source so you can modify it to add all sorts of additional features, or find someone else that has already added this or that and get code from them. The MS Forum has tons of information, and it is easy to find out (almost) anything you need to know about.

I'm not sure what OBDII stuff you need to retain (unless you are in a state that does emmissions testing), so the MS would allow you to strip pounds of wiring out of a vehicle since it will run fuel, spark, idle, etc... (ok, not entirely, OBDII does run the instument pannel and speedometer, so the computer may be required for some of that) So actually, what you would do is simply bypass the stock computer's fuel pump, injector, edis (spark), idle controls while leaving the stock sensors to give feed-back for the gauges as you would if you put any stand-alone system in a Countour (or any car). Or stip out the stock cluster, build a custom instrument panel with aftermarket gauges, gut all the now usless wiring and rejoice at the simplicity of the new MegaSquirt harness you put in to replace it all.

I mean who needs all the extra junk like PATS, cruise, and ABS? (actually if you're good you good rig cruise and ABS to run independantly too.)

And all of this is why the guys at Grassroots Motorsports love this thing, especially for hardcore projects.

I saw this thread name, and immediately thought of Kim.





Carry on.
