Microchips.
Your vocabulary needs work but you are very "articulate".
you can describe what your trying to say very well Smile

SuperHessu Wrote:3. There was a wire on the board connecting two dots that werent originally connected.

JMR mentions that there is a jumper/wire that needs cutting/joining to enable the race map. Please post pictures of where this is done.

Also the resistors are a known trick. They are probably on the water temp sensor to make the car run rich. Possibly some variable resistors to alternate the map signal to force timing changes.
Igt->Igf is probably joined also.
