Not at all! I'm running a Fast Sportsman ECU. I entered the Displacement, # cylinders, # injectors, and injector flow rate into the software. Adjusted the TPS sensor to 0.5V and set the fuel pressure. Rough set the timing with the dual sync and she fired right up. After it was running I set the final timing with a timing light and balanced the throttle bodies. With this I was easily >95% there.

The software in aftermarket ECUs like the Sportsman and Holley Terminator combined with wide band O2 sensors are so good these days just about anyone can easily get an engine up and running.



A word of caution though. The Sportsman and Terminator are high(er) end ECUs, they cost more but have a lot more capabilities. Less expensive systems like the EZ and Holley Sniper that advertise as being self-tuning often leave a lot to be desired. IMO it's truly a case f getting what you pay for.
