Karl,
Personally I think you only need 2 gauges to look at AFR & oil pressure, these are the 2 most important bits of information you need while driving in my opinion, plus there’s only so much you can read when rushing around a track or private road! Admittedly it’s still nice to see what’s been happening after you’ve got out of the car.
I remember going around Castle Combe in my friend Cosworth everything was fine until the AFR‘s went very high all of a sudden for no apparent reason, car still seemed fine and drove ok, but my friend decided to slow down and went straight into the paddock, lifted the bonnet where I noticed the vacuum pipe from the fuel pressure regulator to the inlet manifold had come off causing the weak mixture!!!!, once refitted everything was fine. If my mate hadn’t had that gauge we would have never known the mixture had gone weak and probably blown the engine up within minutes….. |
