Call me overly skeptical, but I have a really hard time believing that any of the more commercialized products are any better when it comes to reliability. I don't know for a fact but I doubt that 034, AEM etc, short of a true industrial electronics company like Bosch or Siemens, with the experience and resources required for a serious development cycle, are really as sorted as you guys make it sound. If Texas Instruments came out with...

What Cam said is really true. Not even for just DIY folks either. I started doing custom EFI work in 2001. I built my own MS unit and installed into my first custom turbo car. I didn't have the money at the time with everything else that I needed to purchase a system like Autronic or whatever. And there is nothing wrong with that, however, from my positive experience overall with the system I have had many people approach me with...

VEMS, from what i recall, was a big jump forward from MS1, but unless it has been updated, is slower than a MS2. In processing power the MS1, and things close to it, are pretty slow. That is a reasonable limitation in itself. The "up" from there can be way up, and largely budget dependent.

Pantera EFI = 034. I ran the Stage IIc on my turbo M3 and liked it. The 1050 does not have a built in coil driver and will require an ignition box or driver from another car.

Does the 1050 need an ignition module?
