Do i need pull up resistor on my Q45 MAF

Post by Meguiars »

Hi, i have tried "again" to get my Nissan Q45 MAF to work with my ms3pro. Im on MAP now but ive heard that the car runs smoother with maf. The car is a Datsun 280z with "81 L28et Turbo engine from nissan. Or should i get a Nissan 350z maf?

I have wired it as i "think" it should be according to ms manual. But it wont change the voltage or registrating any airflow, i have read somewhere that i should use a pull up resistor to get any readings. Is that correct? And f so what resistor dio i need to use?

Thanx

I have attached and older .msl log, but i can take a new one tomorrow.

I thought those were all voltage mafs and did not need pull up.
