Hello everyone, I am new to the forum. I have a 95 pontiac bonneville ssei. The obd port is obd2 but the codes retrieved are obd1. With being said I cant use a regular obd2 scanner. A pontiac forum I visit says its an obd1.5. I would like to lower the cooling fan start temp. I would like to know if the vcm suite is compatible for my car. Is there something anyone can suggest? Thanks
