It’s a great question Radek…and it’s something I’ve been thinking about and chatting with the Canadian ViPEC distributor about. Both he and I will be conducting a few tests to try to shed some light on it. As for controlling injectors and reading sensors, every system on the market uses its own logic to decipher what to do with the information. In my head, it is not that far fetched to think that some of the logic some engineers use is better than others. If there was only one way ot do it we would not have as many ECU options as we do. Also, please don’t get me wrong. AEM is a decent system…but I won’t be putting one back in my car. I’ll leave it at that. --- _[View the full topic](https://forums.speedlife.net/t/vipec-ecus-u2ndyno-com-has-em/119956)._
