Which is better? EMS,MS,PRS,E-manage?, Which is best, cheap and good for an ECU Options

[soulshadow]

Hey, I was wondering which electronic is good for my car. Should I get an Piggyback system like Megasquirt, or should I get an Engine managment system?
I need something that is affordable, reliable, and fast. Some things im looking for is the programability of using a Laptop and the need for less hardware to buy (eg. sensors, new parts that have to be wield on, or take engine apart just to put it on).

Any suggestions?

emanage wont work too well if your ECU is fried, nor will any piggyback system

SDS runs off of a hall sensor, which requires a custom braket that holds the sensor near the crank pully and then for a 4cyl drilling 3 holes in the pulley for magnets.

its a good amount of work, but its not that hard

megasquirt is good, you can probably have a complete setup for $400. the sensors are cheap, or you can get them at a junkyard, i actually have 4 sets of IAT's and CHT's that are used in MS setups

wiring the SDS is much easier, you tell them when you order, what engien you have, and they make a harness

with megasquirt, you have to make the harness

either way, if you dont have time, go buy a replacement 4age ECU. i have personal experience with both SDS and MSnS. they take time to setup and get running properly
