I just bought a car with Megasquirt--unknown version
The car has obvious driveability issues due to tuning and possible mismatched components.
The Megasquirt system is about 6 years old. Would that make it a MS1?
I have no paperwork, software, or info. The controller box is just a silver box in the glove compartment with no markings. I was just told that it was Megasquirt and that they think the original owner/builder used Megatune to tune it.
Where can I download the MS tuning software? I was told I could download it for free?
How do I get started?
Thanks!

Tuner Studio is the latest tuning software, and can be downloaded for free. It is fully functional, but for a small fee you get even more functions. ;-) However, the free version will get you started.

Re: I just bought a car with Megasquirt--unknown version
I am currently on a business trip to NYC. I will take the cover off when I get home and check it out. I had the car for a day before I left to come here. I drove it 4 hours to my home garage in the rain and that's all the experience I have with the car.
It as a 4cyl SOHC 2.6 Mitsubishi engine in a '89 Starion. It has been converted to MPI and it has a 284h cam, 1000cc injectors, AEM wideband O2, Aeromotive FPR, custom equal length stainless header, 3" exhaust, and a GT35R turbo along with a laundry list of goodies but it is a slug and poweress until 4500rpm. Even after 4500rpm it doesn't pull like it should. It is a slug and builds boost slowly ad is very laggy. It has a slight backfire/pop at 2200rpm under slight load such as being in 3rd gear at 30mph or 4th at 40mph. It almost feels as if the timing isn't advancing properly--and it's still running the factory distributor and ignition except for a MSD box and Blaster 2 EFI coil.
Along with being improperly tuned I think the cam isn't degreed properly, the turbo A/R is wrong, or the distributor/timing are off. The first thing I will most likely do is swap back to a stock cam and check timing.
In the meantime I want to be ready to check on the current tuning that is in the Megasquirt and see if it looks ok to a few folks I know locally and to others online that are willing to help. I would like to do some datalogging as well.
