Quick Speed denisty conversion question.

[Perkul8r]

So after having some little problems with my car, i have it running again. Only to find out my maf is not good. Now, i have a friend that wrecked his car and is selling his speed density harness and sensors for cheap. Now all the searching i have done talks about people using the setup with some sort of tuning. And i was just wondering if you can run it on a stock ECU. I am saving up some money to buy a dsm link. So i will have some sort of data logging in the hopefully near future. Just kinda wanna get the car back on the road. Thanks.
