I just used Chris Foley's excellent rebuild kit on my leaky MPS. After removing the spider webs and varnish it all went together nicely. Chris gave me some great tips on getting an initial set. I think it is there but I don't have any experience with how a well tuned djet 2.0 914 should run. I suspect there is probably 150k or so on this engine although it could be lower, I doubt higher unless it was cared for very very well. Impossible to know with the dead odometer. Compression is great on all cylinders with no variability.
I took a little video of a drive, start up, corners, and two pulls to 60 (of various quality). After the first 40 seconds I opened my sliding rear window so you can hear the engine sounds better. https://youtu.be/Fi4vFCWhlCw |

I don't know how I feel about that.... The outer stop is important about not nearly as important as the inner two. If someone told me they had messed with only the stop it would take me no time at all to set it back to where it should be. It's the relationship between the inner and outer and then the trickle down effects on the stop that are a beast. Particularly when you have changed the engine from stock.
That said, the device looks great, so does the software. |

That said, the device looks great, so does the software. Setting the inner screw position (a critical first step when tuning an MPS) can be set using only a vacuum pump and measuring point the diaphragm is against the part load stop. Seems like one could then use the app to set both the outer screw as well as the full load stop screw. |
