Did you have to reprogram that ebay ECM?

[@averagedrivewaymechanic300]

No if you buy it from the link they actually reprogram for you using your Vin

[@edgaraguilar9151]

​@averagedrivewaymechanic300 I might have fried mine when I was welding.. its in a swap. So I dont have a Vin to work with any tips??

Next time you need to do a video let the music stay where its at we can't hear you and the music at the same time

[@averagedrivewaymechanic300]

Sounds good buddy! Hope I can still get your sub 😁

[@averagedrivewaymechanic300]

I do have a second video also about a bad ECM no music 😅
