I did MegaSquirt my 280SL-85 (m110) a year ago, both fuel and ignition and the engine runs better then ever before. I have installed a Wide band lambda and gauge which MS use to hit the AFR Target.

My question is how lean I can set the AFR on my engine depending on it's character. I have no ...

The correct solution is of course to mount something on the fuel return line which hold the pressure between the fuel pump's "one way Valve" and the return line, if anyone have any suggestion, please share it.
ps. maby the old fuel accumulator from the Bosch K-Jet system will work, maby worth a try ...

Hmm... Alter the length of the priming signal... Haven't thought of that.
Maby one can put a big condensator to hold the relay voltage for a little longer but it would have been much easier to just change the lenght in the software.
I have replaced an old K-Jet on my 280 SL and it had an fuel ...

I have the same problem too.. my Malpassi FPR doesn't hold the pressure after the priming pulse either, searching for a solution though...

I understand that it's hard to translate the old settings to a new map but I only need a hint from where I can start fine tune from, this is how I think it should look like (due to several examples I found on the net).
At WOT-> rich mix ->quick burn of fuel, less advance than at lower load.

I'm trying to create a ignition table using the advance/retard from the engine specifications.
I have a NA engine (m110) in a MB280 SL which I converted to a MS2 v3 system controlling both fuel and ignition.
I'm not really sure how I should interpret the timing spec for the engine.
Does the "vacuum ...

Not the same engine but maby we can share some info during the process ...
