comment on the above - i have used EGT to flag a cockpit warning light when
EGT runs too high for too long (running open loop ECU with turbo +
injection)
as a counter to accidentally running high WOT EGT.  crude, but it works well
enough when you're DIY at this game.  originally intended having it trigger
water/methanol injection to lower temps - abandoned idea as we are talking
fast road use here not track (i don't want to have to fill a container with
MW50
every now and again).   mebbe use EGT as additional feedback into ECU to
avoid ye meltdown syndrome? comments?
