megasquirt rules if your on a budget and you have someone to ask question...my main issue with it is that due to its nature (DIY) you end up having to know a bit about it to get it to work...

Plus a lot of tuners wouldnt touch it when it first came on the scene a few yrs ago.....

Megasquirts main advantage IMO is that its software is open source, it probably has in excess of thousands of people all imputting int o its development and features, they offer baby boards..upgrades etc..all free of charge.

If you know what your doing a bit then you cant go far wrong with a MS setup.
