Thread: Problem has been solved

I had a problem.
Every time after the disco came to ~75°C ,at a stop the rev go down and the engine is shot.
To keep it working, I put the rpm so it will not go down 500-750rpm.
After cleaning every sensor, replacing some other sensors, checking every option with your and other help, I finally found the problem.
It’s the "tune select resistor" (see attach) I don't remember if it was the correct color or it wasn't good, but after replacing it, everything is 100% O.K.

To your knowledge.

By the way, i done the BEE coil and module and the disco is not stronger or more economical, but it work much smoother and it feel much beter, so thanks.

The tune resistor chooses the fuel map that the ECU uses.

It is very rare but I guess if it is damaged and open circuit it could confuse the ECU, but I think it defaults to a tune. It may be that the tune it picks may be a catalyst tune that calls for a rich MAF setting.
