Twin Throttle bodies and Supercharger

Hello,

I'm doing the online course and so far it has been fantastic so thanks for that. I'm putting a Link Thunder ECU in a V8 Mercedes that has a supercharger and two throttle bodies. This is not a factory configuration hence the need for the standalone ECU. I don't have any automotive background but with a help of a friend who is a mechanic we've done a lot of the mechanical and fabrication work ourselves. This includes equal length exhaust manifolds, manual gearbox conversion, redesigning the big supercharger kit for better air and water flow and adding a second TB. Therefore wiring in and programming the ECU seems like a logical step to try and attempt to do myself.

This brings me to my question on fuelling table for the map. In the video (Fuel Table Configuration) it was mentioned that my particular configuration of multi TB and forced induction is beyond the scope of the tutorial and should be only attempted by tuners with experience. I'm too involved with my project and have now taken the HPA course on tuning it so would like to know what is required to successfully create a base map for my car. To complicate matters more, the car has a newly built engine that needs breaking in.

So ideally I need some guidance please. In the form of the tutorial or forum questions/answers.

Thanks.

Actually in your configuration the tuning process is the same as if you were running a single throttle. It only gets complex if you're running individual throttle bodies without a common plenum. With your engine you would simply use MAP?MGP as your load axis and tune as described in the course.

Ah, I see. Of course, I have a single plenum and one MAP sensor. Thank you for clarifying Andre.

No problem! Make sure that your two throttle bodies are synchronised too :)
