Hi All -
I remember reading this thread - Boost sag? No, you don't need EBC.
years ago, and amending my setup to suit.
I currently run a Gizzmo EBC, on my Greddy'd car. I'm installing a standalone, and the advice from the ECU suppliers is 'use our boost control'.
Fine. Except - using the engine ECU to control boost means using the ECU's MAP sensor. I.E. the sensor measuring the manifold - after the throttle plate. That's right place to measure what's going into your engine, but surely not the right place to measure what your turbo is outputting.
Surely this puts you into the situation described on that thread ^ where on a long part throttle drag, your turbo is working crazy to force air past a tiny throttle opening, creating loads of heat and pain?
So why would it seem to be preferential, as everyone with MS or other standalone seems to think, to have your ECU doing your boost control?
(On the basis you only have 1 MAP sensor on your ECU, I'm sure there may be some that have thought about that).
