I suppose it depends on what "complicated" is to you. I mean "you" generally, not any specific members of this forum. I'd rather fill out and modify a table on a laptop than buy springs, diaphragms and jets, bend over a 914 engine bay and huff gas fumes. But that's my preference. I like the immediate gratification and feedback of programmable engine management, and auto-tuning and tweaking fuel maps with wideband O2 is a pretty cool and empowering backyard tuning experience.

I'm not a tuning pro nor am I here to argue or convince anyone of anything. If the topic of FI and programmable spark are of interest to you, do some research, then have some fun learning and doing something new. Seriously, nothing about mucking with an engine is cheap or easy.

I found Cramer's book to be a good read when I was doing my first tuning, probably a good starting point for anyone interested in the topic.

Well yes it is my opinion but this is what I base it upon:

30+ years VW engine building, 25 years performance engine building.

I was one of the first here playing with programmable fuel injection with crankfire ignition, I turned Jake Raby onto SDS at least a dozen years ago (IMG:style_emoticons/default/shades.gif)
I've also built a few performance engines, I'd say there's only a few guys here that have built more.

My personal 1967 bug Engine
2.6L T4 engine conversion, handmade shroud
SDS EFI with crankfire, WMS wideband
46mm ITB's custom modified from suzuki TB's, 55lbs deka injectors, custom linkage and fuel rails
102X78mm, CB rods, all german bearings
914 heads 44X38mm SI valves, 12mm plugs opened to 103 built by me,
dual springs, Berg CrMo retainers and keepers, manton pushrods, 911 adjusters, spacers
102mm Nickies with custom pocket JE's and oil pin oiling mod
webcam, ceramic lifters,
Full flow oiling system, 30mm type 1 pump, remote filter, custom windage tray
A1 header, custom engine bar
911-901 trans

I also built another engine with almost the exact same specs as this one (103X78mm) except 44 webers and mallory distributor. The engines were very similar I say the carb engine had a hair more top end power while my FI engine had a bit better fuel mileage.
