 Is the injector resistor pack the same for 1.8/2.0, 1975 914 (tuns out to be the speed limiter )CA only |

I am converting my 1.8 to a factory 2.0 with an engine swap with harness and ECU. Will my resistor pac from my 1.8 work for the 2.0?

Not completely sure of the question. Are you going to D-Jet for the 2.0? D-Jet doesn't use a resistor pack like L-Jet on the 1.8.

Yes it is a d jet, I have a white wide blade connector near the battery that i am trying to determine what it plugs into. Look like the same plug for the resistor block??? (IMG:style_emoticons/default/confused24.gif)
Robert My 75 1.8 resistor block did plug into the socket, so I'm confused ? It was thinking the Djet did not use resistors -Robert |

The one wire single wide blade should be in a single pole box housing. It connects to the cyl head temp sensor near cyl 3.

Speed limiter? Do i have to find one or will it work without it installed?

OH. You have an FI harness from a 1975-76 2.0L CA-only model, which includes the speed limiter accessory. Even though it has the same connector as an L-jet resistor pack, DO NOT PLUG IN THE RESISTOR PACK. You can run without the speed limiter, just leave that branch dangling with nothing connected

Rev limiter. It cuts off the fuel above a certain RPM as an emissions device.

Porsche, or Bosch, noticed that it wasn't such a good idea to cut the spark to limit the RPMs when you have a catalyst in the exhaust. Because cutting the spark means you have fuel still going through the engine, and the catalyst gets nice and hot... Wanna guess what can happen there?
So they implemented the rev limiter by cutting the fuel. I believe the limiter interrupts the signal from the trigger points when they start signaling too quickly. --DD |
