Here is one good example of what you can expect in a quality ecu. While tuning a customers car I noticed that the injector duty cycles were abnormally high. After pulling up a datalog I noticed the fuel pressure was dropping off rapidly under boost.
The customer had opted for a Link ECU Storm which has the capability of utilizing a fuel pressure sensor input for the fuel calculations. As you can see the fuel pressure dropped all the way to 22 psi and the fuel curve never missed a beat. Fortunately on this car it was a simple issue but if you had a pump failure or a plugged filter while using a lesser ecu this could easily cause engine failure. This is one of many benefits of a good ecu.
Choose wisely. If you have any questions - please do not hesitate to call me.
