A friend wishes to remove from his car the n2mb wot box in order to install to his car the NLS & LC function.
We remove it but we ve faced a problem.
Wot box was installed by cutting the two ground ignition coils (black / purple color code) cables which are feeding ignition coil fuses at port 1. After removing it, those cables must be connected together. To be more specific this ground connection is one cable which is splitted to 2 and after to 4 in order to feed each ignition coil separately.
Wot box uses one cable to manage the ground signal. So we dont connect those two cables we cut, one by one, but we use one ,a bit bigger copper wire, think it is 2.25 thick, and connect them together. First we join the cables together and check that are joined ok with a multimeter, after we solder them and cover them with shrink heated tube.
Car is starting fine and under 4000rpm works as before. After 4000rpms on full throttle is misfiring very badly and non go.
What could be wrong?
Shall we desolder them and use 1.5 thick cable and connect each cable separately?
Any suggestions are welcome
