The car is new to me and I read that the 86/87 ECU would be a plug in replacement. I bought one and it did not come with a chip at all. I want to get the car to a base line to scan it and see how to proceed. Since I don't have any history on the car I am working in the dark. I was told the engine was rebuilt and it is painted a different color. The block casting number says it is a 82 block. It runs ok under part throttle but if I floor it the engine starts to ping and it looses power. Back on part throttle it runs fine again. I came with a Hyper Tech 424012. I have no experience with Buick Tubo's so I am learning as I go.
What would you suggest for a chip and what is the cost shipped to 20194.
Thanks
