For proper diagnosis and tuning of D jet you need these items: the factory manual, a good multi meter, time, money. You really need to take your time to diagnose every circuit to ensure its within spec, there are no wiring issues, connector issues (common), etc. And of course, to understand how it all works together. When you actually need to replace parts (likely), injectors, trigger points, MPS sensors, and ECUs are all expensive. You need to take the time to repin and replace connectors that are damaged or corroded.
I've been doing a lot of this lately. I just finished a 3.5 that was a real disaster - lots of incorrect parts and tuning by mechanics who had no business working on these cars. It would have been much easier to work with a car not running but in original condition. Ended up taking me about 25 hours of working for a total bill for the customer of around $8000. That was just to get the car running properly, there is still much more to do. On the flip side, my 280SE 4.5 has about 3000 miles on the engine I rebuilt this spring. On the last tank of fuel I averaged 14.5 mpg, which is pretty damn good! Took some time to get it really dialed in, especially the MPS. I've been measuring them and making adjustments on used units to bring them back to new and it's really successful. Overall, the 380SL is a better car in lots of ways. The 450SL has more power, but power isn't everything. But I'd probably buy the one in better condition cosmetically.
