#106144, "Warning: Dont Jump Start With Turbo Timer Connected"
Thats right, you read it correctly. If you jump Start a car with a Greddy FATT connected, you run the chance of damaging the TT. I did it a few times to mine in the past, any issue was resolved by disconnecting the TT and letting it reset. Not this last time.
After a loud long warning squeel from the TT it failed to operate and displayed 3 backwards C's. After 3 days of searching the Net i found many othr cases in various other automotive platforms that resulted in the TT being damaged during jump starting situations. All Greddy FATT models too.
