Hi everyone,
Everything on my car has been running pretty well, so I haven't been able to tinker on it much on the B4. In the meantime I've devised a theoretical way I can switch to parallel instead of sequential at the press of a button, using a bunch of old solenoids I have.
The biggest question I have regarding this is the tuning. Will the ECU need any special configuration to cope with this, or as so long as it sees boost within a certain range it will run fine? Keep in mind my car is already retuned with better flowing turbos and other mods.
The reason I want to experiment with this is even though the VOD has mostly been removed, on the go cart tracks that I often race on I'm finding the revs fall back into the single turbo territory in tight corners, but only just, and I feel that the car would perform better if both turbos remained active coming out of the corner. I could change down to first, but that's a bitch. Rather than go through the full process of spooling the primary then the secondary, at those revs it would surely be more efficient to spool both at once.
Anyway, even if it proves not to give me any power gains on the track, I'd still like to try it so long as it won't cause any tune issues (e.g. leaning out).
Thoughts?
