Greetings Dave- hope this issue gets resolved!

fwiw- I recall from a Hot Rod Forum post ~24 mos ago:
... of an E500 owner whom indicated that he was getting rid of his 124.036 and observed power/tq decrease over the life of his deemed healthy '94 E500.

I believe he also shared that he's owned 3 different 124.036's and was moving toward a 400HP Jag type R as his incoming replacement.

Have you had a detailed chat yet with Carl at Bergwerks, Donnie from MB Autowerks, M.B. Doc, Bruce Strauss in S Cal, Steve Brotherton of Continental Imports, or any techs here on this board regarding testing procedures and proper operation of the cam advance for your ''94?

Carl replied to my post over on the 500E.com forum (linked earlier in this thread), but haven't heard from him since then. He thinks my elevation (2400ft) is part of the problem, which it may be, but I think there's something else amiss. I'm hoping a dyno run might shed some light on things. If the cams are advancing normally, then I'm really stumped...

Dave, what was the outcome ?

Woops - forgot to update this thread! Better late than never, eh? Basically, it was a non-issue... extensive dragstrip testing has proven that the car is running normally for a 500E, at my elevation (2700'). At a sea level dragstrip, it was faster (as expected), and I also had traction problems when launching... indicating improved low-end power at lower elevation.

However, the temperature-related power drop remains... when the engine is cold to cool (say, 50-70°C on the dash gauge) the car will spin the tires much more easily. At 90°C and up, it will only spin the tires if ambient temps are fairly low (say, under 60°F). When I originally started this thread it was in the middle of summer heat (July) and the car pretty much refuses to spin the tires in summer, unless engine temp is ~60°C. I wish there was a way to produce that "extra" power at normal operating temps (80-100°C) but I doubt that will happen as long as the LH engine management system is in control. I believe this is "normal" and there's probably nothing wrong with my car. (If yours will fry the tires on a hot summer day with no problems... then maybe I do still have something wrong! )

Hope that helps - let me know if you have any more questions. I'm still planning on a dyno run.
