Thx people for your quick answers!
Davic C, I’ve done more than 4 remap to make several adjustments…but my “repro tuner” friend, can’t find the correct map that corrects this problem!
Alfa maps are very complex and very hard to remap…for example, do you know that there are 4 different speed limiters, that with them you may not give more top speed in spite many HP you could have?
Mine its in limp mode right now…and I’m really sad because I couldn’t find any real solution to this problem!
Jomor, here’s an example how lambda works…
And several examples I’ve find over the net with solution to this problem in Fords and Subaru’s….
Basically they use all the same diagram…but the only thing it changes from car to car…it’s the wires colour!
After I’ve find the right polarity, I’ve used these diagram in my sensor…and I’ve found that depending on the resistor I’ve use…and in the installation (low-pass filter), or not…the engine gets more or less fuel!
That’s why with this mod I could get little more power, cause I have more fuel…but with error on (Motor Control System Failure), the engine doesn’t have full power cause don’t use correct (performance) maps!
