Brought two of my 3 MPS back to L.A. from Indiana while I await the arrival of my LCR55A so that I could do some bench plotting and tuning only to find that neither one of the now holds any sort of a vacuum.
Both ran fine in the car before flight - just needed some adjustment. One has the factory plug replaced with a Tangerine model - the other is still factory sealed. Did being in the unpressurized cargo area in my checked baggage blow them both? That would really stink.... Brian |

Let’s review:
Fact: D-jet does not run properly when unmetered air leakage is present anywhere in the system. Fact: The sole purpose of the MPS is to accurately measure manifold vacuum in order to set fuel mixture. Fact: the MPS cannot accurately measure manifold vacuum if the MPS is not sealed and is leaking. This is no different than using a modern EFI MAP sensor and drilling a hole into its inlet. It will not be capable of measuring properly. A leak at the MPS is no different than an air leak anywhere else as far as D-jet goes. |
