Question and Answer

Hi can this work on my VQ35 v6 pathfinder engine? Oct 19, 2020
Best Answer:Hi, This is a universal engine control module and not vehicle specific. It is usually used for GM TPI and Holley Stealth Ram. We recommend getting the direct fit. But, if you can no longer find it, you may the manufacturer Holley at 1-866-464-6553 and ask them the correct part number that will fit the vehicle.

Would you recommend this for a 1987 IROC with the 5.7?  The ECM on mine is damaged.  ThanksToddOct 06, 2020
Best Answer:Hi Todd, We only have universal ECM for the 1987 Chevrolet Camaro Iroc-Z 8 Cyl 5.7L. I would recommend for you to call the manufacturer Holley at 1-866-464-6553 and ask them the correct part number that will fit the vehicle.
