What modern EFI systems is everyone installing on their Type-IV engine?

Now before I start this post, I am not in anyway an aftermarket EFI guru. I probably know just enough to get me into trouble. I come from an era of 55 chevys and air cooled VWs. When I have a EFI problem, I go to a guru.

That being said, another alternative for EFI you may want to look at is VEMS. A lot of the Audi guys are using this, and they are making some insane horsepower from 5 cyclinder motors.

My EFI guru is a guy named Mark Swanson at EFI Express. He replaced my 034 EFI with VEMS, basically because 034 is no longer supporting their product. VEMS is. Mark is a tuning and wiring guru. He makes his own harnesses.

While I was back there he was converting a 914 1.7 from CB to Megasquirt. One of problems he was having was timing. Now this customer did not want to spend a lot of money, pulling the motor and such to install a crank trigger was not in the budget. To get by this Mark was using the distributor, with a digital sensor. I don't know the brand. He was having trouble with the mechanical advance on the timing. Since the MQ does the timing for you, he eliminated the advance springs and welded the 2 plates together.

So if any one contemplating doing a conversion to MQ or more advanced EFI such as VEMS, and live in the Northeast, you may want to see this man.

One of the other cars he was working on while I was there, was a Ferrari Testarossa. He was installing twin hamster cages and VEMS.

Just for the hell of it, this is the dyno run on my other car, at his shop.
