Well, no updates on this thread for almost 3 years but with renewed forum interest in aftermarket EFI, I thought...why not.
To be honest, I haven't touched the tune on this car for about 30 months. It ran too consistent and I didn't' want to mess with it. That coupled with a very short commute to work made tuning unnecessary. However, the commute just got longer so I'll be back to doing some tuning in the coming weeks.
As for problems I've had with my MS install, to date I've had the following issues with the install.......NONE.
I have about 15,000 miles on the install and the MS was a champ all the way up until bambi's mother decided to try to kill me. It's taken over 5 months to get my insurance company (USAA) and my local classic Benz restoration specialist (definitely not words I'd use to describe them) to get my car back to me. Now I've been re-doing all the things they did wrong (new radiator shroud, fan clutch, AC temp switch for the aux fan) and due to their inability to fill the trans correctly, I'm in the middle of a trans swap in the old girl (she had a flair from 1-2 prior to, but now she has a FLAIR>>>>>>>> from 1 to 2, so out with the old and in with the new.
I did a trip to DC a month or so ago and even with some in-town driving on the tank, I got about 18MPG.
I have a new, more aggressive, ignition map I'm going to try after I get the trans figured out tomorrow. While she runs great, I'm bringing spark advance in way too late so she is a bit of a dog from 10-35 mph.
Anyone looking for reliability in an old D-Jet system that is on its last leg (as mine was), if you do it right, the MS really is a good system.
And to all the purists out there, I get it and respect it. My car was never going to be restored to perfection, so I chose to make her drive-able but still a classic looking W108.
