There are a few on here using megasquirt, tho they are spread out among a few different places (not all on LS motors). Better for the money is a tough question.

IMO, running HP tuners on the stock ecm is the easiest thing to do, unless your needing something unusual that the configuration can't handle. The advantages of MS are its customizeability, but if you don't need that level of custom-ness, its got a steep learning curve.

What I mean is; if you need something like extra injectors, building in something like a 2step, special fuels or running several types of fuel, thats where MS shines. Being able to control methanol from the MS is awesome...but that being said, you pay a certain price for that.

The cost of the system, the learning curve, the use of specialty hardware (the ecm I mean), are not something everyone wants to deal with.

Back to the "for the money" discussion. What we really need to know is, how badly do you need (want?) a stand-alone system? MS is great, but there are some other good alternatives...as well as all the variations of the stock-type ECM/harness setups that can (And have) been made to work for thousands of applications.
