Resistor Mod: Not impressed
I am by no means a mechanic in any industry. I'm just dumb enough to try things I see here.
I got my set up completed last night with a rotary switch that lets me select between 5 resistors. 3.9K, 4.7K, 5.6K, 7.8K, 10K and OFF.
I DO know that the only setting that might give me results is 5.6K. But I have not been able to do any actual testing. For the time being, I will say that 5.6K seems compareable to the OFF position. I did not notice any engine loping nor any smoke.
The other settings gave a very noticable lope to the point the engine would barely run at idle. The van would barely move at any accelerator position. I could have pushed my van faster.
I already seem to have good acceleration...I wonder if the previous owner installed a chip. ???
So, at this point I will eventually do testing compareing OFF to 5.6K. As I said previously I don't see a big difference yet. I keep tabs on my fuel mileage so I will be sure to mention in later posts if 5.6K gives better or worse MPG results than stock.
