At first I thought what you wanted to go with, but if your thinking on which kind of MS system's your looking at, here's a copy/paste of the last group buy's information
For those who don’t know Megasquirt in its most BASIC form is a standalone fuel computer that grants users full control over the fuel curves and allows use of different injectors for boosted people. With modification, the Megasquirt unit can be converted from a basic fuel computer into a complete standalone engine management system that rival most existing high priced units out there.
COIL PACK IGNITION CONTROL IS AN OPTION!
Dead distributor? Dieing igniters? Instead of paying hundreds of dollars for a stock replacement or hacking apart the distributor to go with MSD, consider Coil Packs! Coil pack ignition allows for ample dwell time between each spark even at high engine speeds. Traditional distributed spark ignition systems have 1 coil that provides spark for all 6 cylinders. The drawback here is that at high rpm the coil doesn’t have enough time between each adjacent spark to fully charge, thus causing a reduction in spark voltage and engine power. This can cause spark to blow out at higher rpm, especially with modified engines that are turbocharged or run nitrous. A coil pack ignition system has three coils, meaning each coil does 1/3rd the work and has 3x the time to charge between each spark. This type of an ignition system is capable of developing the same high power spark at all engine rpm’s even with a larger more efficient spark plug gap. These things combined will also help you develop better engine response through the rpm range and higher efficiency as well, with proper tuning this will lead not only to better performance, but better fuel economy as well.
The Goods!!!
All of the units will be capable of driving high impedance injectors (like modded Nissans, Millenia S, etc) and controlling timing directly. The basic operating functions will still fall to the stock computer. This includes Idle control, EGR, purge, a/c, etc. Base tunes will be included for a variety of setups (KLZE, Turbo, Supercharged, etc) that will get you up and driving around with your newfound power, but still on the safe side.
This does NOT mean as soon as you get it running you go out to the races or the track. User error on this part could lead to a broken motor, so be careful and go slowly. Access to a dyno, wideband, and experience tuner is highly recommended. I do travel to offer tuning and install services, but it is VERY expensive so I try to offer as much possible help here on PT and via E-mail. Any discussion of my travel will remain in PM. If you post about it, it will be removed from the thread.
ECONOMY UNIT: $275
This Megasquirt will be powered by a version 2.2 PCB and will not carry all of the extra features that the v3 boards have, but in many cases, a V3 boards extra features are not necessary for everybody. In order to use this, your car will REQUIRE the use of a 92-94 distributor. If you have a 95+ KL, you can still go this route, but you will need to purchase an older model distributor and move around 3 wires for it to work properly.
This unit will come prepackaged with:
Two VRIS outputs
Fans Control
Launch Control/Flat Shift
You will be required to set the ignition timing with a timing light, as it is based of the cam sensor in the distributor.
STANDARD UNIT: $390
You will get a fully assembled Megasquirt unit that is compatible with 1993-1997 Ford Probe GT/MX-6 LS, that DOES NOT require any modifications to the engine. Other than wiring the unit (Connector will be included), no other modifications will be necessary to have fully laptop programmable fuel and ignition control. The unit will be able to control any size and type injectors (you are no longer held to the high impedance injector requirement) and the unit will control any year KL v6 engine with its original distributor. Ancillary functions such as evap. emissions control, air conditioning and purge will be left to the stock ECU.
In addition to all the additional features of the v3 board, you will receive the following with the standard unit:
Two VRIS Outputs
Fan Control
Launch/Flatshift
Switchable Tables (for nitrous or race gas)
The V3 Unit will automatically set base ignition timing, so adjusting the distributor will never be a requirement. The v3 also allows for future upgrading, low impedance injectors, coilpack capability, built in VR Decoder (our crankshaft sensor), and increase fault tolerance from over voltage situations.
DELUXE UNIT: $500
This includes EVERYTHING in the standard unit PLUS the ability to run a coil pack ignition system…also known as DIS. Do NOT confuse this with EDIS. EDIS is a self contained system that does indeed use coil packs, but you will not have the ability to cut spark for any launch control or flat shift purpose. If you don’t know, cutting fuel in a batch fire injection system is dangerous and should only be a last resort. In order to use coil packs, you will be required to keep the base of the distributor because it houses a necessary cam sensor.
