there is alot of extra censers cuz it is obd2 and obd1 has like 120 or so obd2 has 250 or so but over all they really help for 96 with the upgrade u can tell it how much upgrade parts there is not to mention obd2 is smart it knows how much gas to give when u floor it and all while chipping one only tells it more gas so u wast alot and dont gain as much as u can with 2 source is the master mechanic at my work he has over 46 years of experience

thats not at all tru my friend, i understand it very well. The reason I am getting rid of it is acouple reasons. 1 I want the nistune or zimulator programs and niether is available for 96. and I got rid of all the bull shit sensors that I dont need. 95 under is alot simpler of a set up. no power gains or anything like people think though

for the whole 96 ecu upgrade look at jegs they do a ecu upgrade all u need to do is get it reprogrammed to many people on this site dont like the 96 because they dont understand them
