Hey people!
Can I by any means bypass yhe boost sensor?
Im upgrading my electricity and this bastard is taking to much room.

The book doesn't cover the actual use of the boost sensor. The testing of it does tell us that it varies votage from the ignition unit from 3-2 volts so the ignitor must need a voltage signal from it.
Not real sure but I would say that the lower voltage causes an advance in the ignition timing. This means that it is a required component of the ignition system.
If you have the manual you can find the testing procedure starting on page 265.
If you don't have the manual either I or SgtCall can get you a digital copy, PM either one of us with your email and we can send it to you.

Thank you! I have the manual. Just wondering if there is something like a retarder or a smaller unit to hook up to the ignition

As Herb points out, the Boost Sensor alters Ignition Timing.
The net effect is to improve gas mileage.

Boost sensor switches between two types of ignition advance in higher RPM: standard (around 30 degrees) and cruising (around 50 degrees). The second one is better for fuel but will be dangerous on higher load.
If you can cut the boost sensor and set a fixed signal for the high vacuum you will get an ignition like on the older models without the boost sensor.
If think that the signal for low vacuum and cruising ignition is 3V and switching point is vacuum higher that 250mmHg and signal at 2V. It could be done with resistors.

I don't really know if it helps all that much. a few years ago I plugged that vacuum line to the bost sensor and rode it for 5 tanks of gas. The mileage and performance difference was undetectable.
I did the test and it showed the sensor was working correctly.
I don't know what would happen if the electric connection was disconnected.
