LH 2,2 Question
At which engine/water temperature does the LH 2,2 enter open loop/closed loop?
What I´m thinking of is that some Bosch systems provide more pre-ignition and fuel before the engine is quite warmed up. Does the LH 2,2 work the same way?
If the engine is kept or the ECU is made to beleive that the engine has not reached its full operation temperature it will give some more aggressive spark curve. I read about that some people with GM cars place a 640 ohm resistor along with the tempsender that the ECU uses to monitor enginetemp just to fool the ECU and make it belive the engine is about 60-65 °C/145-150 °F.
