Just started my 84 vette, I converted from the crappy crossfire inejction and smog heads to DFI port injection and aluminum fastburns. I'm post the cliffnotes, any questions just ask away.

350 with fastburn heads (aluminum, sodium filled valves)
mercrusier intake (machined to fit extensively)
BBK 1000CFM throttle body
Machined fuel rails
48lb/hr injectors
walbro 255 pump, all AN fittings and aeromotive regulator
small 214/244 cam (similiar to GM HOT cam)
Megasquirt DFI w/zeitronix wideband
long tube headers, dual 3" exhaust, X pipe, GM LT4 mufflers (quiet)

Even with the huge injectors the engine idles well, and revs nicely. The cool thing about megasquirt is that it can tune itself to a lookup AFR table with the wideband directly. Once I get the car on the road I'll finish the high rpm/high MAP values.

Nice

how do you like the megasquirt from a tunability and ease of use standpoint?

I really think megasquirt is the best thing to come out in the tuning market since the wideband O2.

Its very cheap, very easy to use, and extremely powerful. There are not many systems that can do realtime closed loop wideband and autotune like megasquirt, and those that do are usually over $2K.

I paid $140 for my kit, plus soldering time.

I really think it will take off once more people are exposed to it.

what kit di you go with??
i was pricing out the MS2V3 and it was like 260 from DIY for the whole shot witth all the components and the case
