do chips have to be removed to be reprogrammed in general? do any cars allow for in-vehicle reprogramming?
do they use eeprom for 2004 cars?
just trying to get an idea if this is a DIY thing or is a logic analyzer needed to figure things out
yes I can search but i figure there should be some car hackers here that have done some of this how cheaply can it be done?
I'd like to get at the drive-cycle code and all that kind of data
