Blitz DTT help
I just installed my Blitz DTT (Dual Turbo Timer) and this Turbo Timer is in hKPa's vaccum shows at -.78 hKPa's does this mean i'm only at -11psi or is it supposed to mean -1.78 hKPa's which is -24 PSI??? this is weird because when i had my mechanical one in it read -20psi to -11psi under idel and 9.5 psi under WOT which the DTT reads about .67 hkPa so under boost its right but under vaccum its not... anyone have this unit??

ok your car does not make -24psi. vacuum is measured in inches. or known as inches of vacuum. -.78 is about 11 inches of vacuum. your car should idle at about 18-14 inches of vacuum. .67 hkpa or also know as BAR is about 9-10psi. the unit seems to be working fine from what youve described. there is a imperial mode on the unit. its in your manual.

I don't have the orginal manual but form the Blitz website there isn't a Imperial mode. What does this mode do?

imperial is US(psi ect.). but i just found out that the dual doesnt have it. but basicly those numbers are right though there just in metric.
