megasquirt

I have used megasquirt before on my supercharged mini and mk2 golf gti. I am very pleased with the results and have had first hand experience mapping on the rolling road.

Although megasquirt will work with just about any sensors you can get your hands on, likewise with injectors and idle control valves etc it can be a little more tricky to setup beacause of this.

The software for mapping is also not as user friendly as more expensive systems but overall it can all be done with relative ease with research and planning. I have changed some of the code myself to make mapping easier. The steps for ignition setup are 0.1deg steps... In reality this is far too fine... So I made the steps 1deg which is easier to spot the power change on the rolling road.

I personally think they are great for the DIY minded person. Planning is the key to getting what you want from these. Plan for the correct injector size/coil type/idle control type. That way you can configure the ecu build at the building stage.

i built a V3 ms3 with ms3x board with on board sd card data logging, Usb support, fully sequential ignition and injection control. works very nicely and with the new tuner studio pro software and innovate lc1 wideband its very easy to tune.

its harder to set up because it will do almost anything engine wise and using almost any form of sensors and pickups and as for the software there is more than one type.
if you look at the cost i dont think you can complain realy
i do think it is worth paying a little more and go for v3.0 pcb and its worth noting ms1 is a little slow on the prosessor side but should be fine for non cat setups (people are useing ms1 for track and rally cars)
