This is the worst time of year for this to happen–cold air is here now, and this is when EFI tuners need to tune, and when lake racers with carbs like to tune!
Apparently a short in the airflow meter extension cord fried a small $1200 circuit board last week and lost my RPM and turbine signals. I bought a new $1200 board, installed that and got my tach and fuel and air meter readings back but now the torque zero’d out at 60 lb/ft and EGTs read 2050 degrees. So it appears that the fried $1200 board in turn fried something in a larger $4000 main control circuit board. So on Friday 1/8 I shipped three circuit boards from the dyno control console back to SuperFlow for repair, red label. I can’t afford to be down, but I can’t afford to just buy new circuit boards, either! Dyno testing with a modern instrumented facility is expensive, per hour of billed testing time. Dynamometer and driveshaft maintenance, continual software upgrades, snowplowing, energy expenses (heat, water and the cost of running our 7.5 HP air blower), and the brutal New York State school and property taxes equate to $65 per hour of billed testing time!
Enough whining–I tell everyone who listens that when I win the megamillions lottery I will begin doing this for everyone, for free! I feel just a touch of guilt charging people for doing something that is so enjoyable for me–helping people make their sleds run faster with more power! The bad news is statistics was my favorite subject at RIT business school 42 years ago, and subsequently I buy maybe three megamillions lotto tickets each year just for fun.
With some luck, we will be running again late this week, so everyone who was scheduled this weekend and next week will be shoved back a week. I will use this downtime to catch up on DTR stuff to post on the subscribers’ pages.
