I have a ms1 pcb2.2 which have been driven in my budget racer.
I built the "activate low input" according to http://www.msextra.com/doc/ms1extra/MS_ ... m#launchin
and connected to JP1 pin4 it has been working flawlessly about a year (without the diode from 0v to signal input - and using 1n4007 diode instead which should be fine as it just has 1000v reverse voltage instead of 50v like the 1n4001).
The other day i started the car to move it onto the trailer and felt a bit gitty - but it just reved freely.
Tunerstudio says launch input doesnt get activated.
Launch control input is 2.5v when unused, and 0v when activated.
Built another circuit exactly like it just to check something hasnt gone broke, but that didnt work either.
What has gone wrong?????
MS1 - launch worked, now it doesnt
