LC1 gauge not reading right. It stays at a constant 10.1. Not 100% sure that the ms is reading the Wide band correct.
The car does run and drive. just not very good at this point. I think i could maybe even leave it the way it is and be fine .. but does not seem right to me.
I have done a lot of reading and still confused. I want to start with looking at my wiring. I am confident that my wiring is right except for the grounding points.
Here is how I am wired at this point.
1. Blue and White ground to the ECU ground point. Solder to a single ring connector.
2. Gauge ground solder to a ring connector to the ECU ground point.
3. Test button ground solder to a single ring connector to the ECU point.
This seems like to many grounds at one point. the directions state "1. The BEST grounding scheme is all grounds (i.e., ECU, Gauges, LC1 heater, LC1
system, etc.) SOLDERED into a single lug and bolted to the engine block."
I wanted the opinion of others who have done this as to the best set up. i do not mind doing one lug and using the ECU ground point. I still think that is a lot of grounds to one point.
My thinking is to ground the blue and white to the ecu on the one ring.
then ground the gauge and test button to a point on the frame.
I have also read that having the gauge ground at a different point is not good.
i defiantly think getting rid of the test ground is a good idea and just ground it to the frame.
1. leave it like it is on different rings and use the one ground.
2. Blue, White, Gauge solder to one ring and use the ECU ground. then ground the test ground to the frame.
3. Blue white to the same ring and to the ecu ground. Gauge and test ground to ground on the frame.
4. "Stupid Noob you should do none of those and do it this way" Fill in the best way to do it.
I have read many posts on this and I am still confused.
