Anybody running an after market fuel injection system called SDS? Interested in opinions. Thx in advance!

I don't know where you got confused but I haven't forsaken anyone's experience. You need to take a step back and re-read what I posted.

Did I make a comment about anyone's tuning ability? No
Did I make a comment about anyone using a SDS unit? No

I simply stated SDS is old ecu tech, that's just a plain fact.

Do your homework and you'll come to realize I'm correct in that statement.

Here are some ECU manufacturers to start you on your research:
Motec
Link
Haltec
Pectal
Emtron
AEM

Some basic features of newer ecu tech that can benefit 914 owners / tuners:
Sequential ignition and fuel control
Knock detection
Built in Lamda control
Flex fuel capabilities
Multiple trigger input styles (crank wheel, distributor, etc)
OEM sensor calibrations

Just because the engine is older design doesn't mean it can't benefit from newer engine management technology.

I'm not just making blind statements as I am a paid data acquisition consultant and I have over two decades of experience with street and race vehicles.

I get involved in posts like this because I like helping enthusiast get the best equipment for the money they spend. For the price of an SDS unit ($1284 on their site) you can have more than just following the old way of doing it.

No you're ranting about a system you have no fuchsing clue about or have ever used.

Sequential ignition and fuel control, Great for fuel economy at 1000-3000rpm but seeing as you shouldn't lug a T4 below 3000rpm all but useless on a T4.
Knock detection useless on a noisy aircooled engine, but SDS has this option
Built in Lamda control, SDS has this, but you don't control a lambda, you or your ECU reads it
Flex fuel capabilities honestly don't know, I only use pure gas 91, I did run E10 on my 1.8 no problem
Multiple trigger input styles (crank wheel, distributor, etc) SDS will run stock dizzy, MSD or crankfire. I believe now you could use a trigger wheel, COP, etc.
OEM sensor calibrations, SDS works with some OEM, but again doesn't matter on a T4 and for aircooled SDS uses the stock bosch head temp sensor.

SDS has full data logging, real time and/or logged, plug it into a laptop if you like

Good for you!
How many VW/Porsche engines are you building right now? I'm building ten engines, three 996, four T4, two T1 and one 356. Seven are performance builds, I had to add my 6th engine stand.

All require expensive dyno and tuning time, plus a steep learning curve. Most of those systems listed are way more money than SDS
And in this case a basically stock engine, 2056 with a WEB #73 FI cam. Plus I know Ian (the OP) and I know he doesn't want to learn how to program a complex system.

Begs the question why do you need "Engine management" for a simple pushrod 8 valve NA engine based on an 80 year old design?

Ian, I have everything you would need, except the Djet injectors I have are old and would recommend sending them out for service. You would also need a new air filter and the runner hoses. I have the TPS mount, TB, plenum, air cleaner, all set up for SDS. Newer style injectors would require custom made fuel rails.
I also have a new reasonably priced O2 meter with a genuine bosch lambda, I have 5 in stock.
