Hello, I recently had my 1994 Del Sol Si D16Z6 stolen and recovered. I just got it back today and it is parked in my garage (how sadâ€¦). One of the things missing is my ECU. I am looking to replace it to get the car running again, but I am not super knowledgeable about the ECU world. From the basic research I've done, it looks like I need a P28 ECU for a manual transmission? Is that correct? I have looked on eBay and other places, what is the appropriate price I should be paying for a used P28 ECU? I also briefly found a P28 converted to a P06? What does this mean? What is the appropriate price I should pay? Since I have to fork over some cash to buy one, should I get converted/modded/souped up ECU? What will this gain, break, help? Should I trust someone on eBay selling a modded/converted ECU? Much Appreciated!
