Anyone running a MegaSquirt EFI system with boost?

[TT LS2]

Just wanted to get some feed back about the system and the setup along with all of the capabilities.. I am currently looking at the Accel DFI, Mega Squirt, and XFI set-up for a twin-turbo engine. Which of the three is easier to use, adjust, offers less of a headache, etc.?
Thanks for your input/advice.

I think it comes down to personal preference all those systems are capable of doing what you need.

I personally would go with the system, that your local tuner knows best. Your going to need help and support at some point...

Maybe some more details about your combo might help; otherwise you are going to get what most feel is popular (and not actually what you need). I've tuned MS on a boosted ap, but honestly, if you are going with a twin turbo LS_ engine, you're better off with a DFI or FAST setup, as they have harness kits that go from universal to vehicle-specific.

I would look into the VEMS as well, its a system with origins in the megasquirt but based on a larger processor, it can run all eight coils and injectors sequentially, it will drive peak and hold injectors, and will accept dual WBO2's and i think its in the 400 dollar range assembled...

the megasquirt is alittle too basic to run an LS motor with all the outputs needed to drive the coils and injectors...

Planned combo (still in the making):
4.030" bore iron LS1 (actually)
4.0" stroke
GM L92 heads, ported on exhaust side and in chambers
Camshaft-STILL RESEARCHING
Intake-GMPP 4 bbl with injector bungs for, still debating on a Holley flange throttle body or a 90mm monoblade type with a intake elbow.
Turbonetics 62-1 (twins)
Inter-cooled
Max boost-20psi

Looking for 1000hp with combo.

Which efi set-up would yield me those type of results.
I welcome honest, impartial opinions about this stuff.
Which set-ups are easy to use, for this is my first injected engine and this is my first boosted engine. Also, I have no tuning skills at this point. I would like the efi sytem to allow me and my imagination room to grow if I so needed it to as far as HP goes.

Thanks again for your input, guys!

VEMS, huh....
I'll check it out...thanks!

To keep it simple & accesible, I'd say go with a DFI (Gen 8 coming out soon...LOTS of features), or a FAST setup. MS, VEMS, Holley, etc can all do the job- but they don't quite have the deep LS1 support yet (some will undoubtedly argue that). There are other systems out there- but I have more experience with the DFI & FAST on LSx engines.

As one of the team members that invented the 58x (60-2) decode, worked with Wegners on the GM "spider" (have stock),
and manufacture a DSP baised EMS product,
I would suggest looking at my equipment.

My project, the first 1000 HP+ LS-1 for Ro was dyno tested at Westec almost three years ago.

I might have some experince with the Twin-Turbo LS-1.
