Most of the old ECU's are like that. But most of the new ECU's can learn things like driving patterns of the driver and make miner adjustments to improve performance and fuel consumption.
Please google for more info..
I know it because my engine do some crazy things. When I reset my ECU problem goes away for about 400-500 KM and then the craziness comes back again...
It's a learning ECU and due to some error on a sensor ECU is learning something funny. But there's no visible error. So I need to go into cache and see which sensor is giving the wrong info. And for sure it's not giving wrong info all the time.
Got it?
No it's wrong.
Cheap OBD II scanners can't see the errors in cache of a learning ECU (It's not a coded error that I need to check). So this task needs a Professional OBD II scanner and Professional who knows how to do it.
Simply my ECU is learning something that it should not be.
Please tell me if you guys know a good guy for this.
Guys,
I need a person who’s really good in OBD II scanning. Need to check my ECU cache carefully so that a person should be free enough to do it taking time and should have a good knowledge on the thing.
Thanks
