Hi bros and sis I tried to install the original Apexi pen type auto timer on my Copen, but went to 5 WorkShops and no one knows how to fix, and said Apexi can't be used on Copen. but another friend of mine using replica Apexi did and working fine on his copen so he say replica can fit and original one can't. What BS. Then went to buy HKS turbo timer with the same problem. Engine will stall when turn off key. Only Have to rev til 2K RPM will it be able to start countdown with engine running. A mech checked my friend set up and said his was installed with a diode and a relay near the timer console. Anyone know what is that diode and relay for coz mech himself was scratching head too. Even went to audio Workshop also can't help. His was the 6th WS I visited and to no avail.. Anyone using a timer that can just fix and use rather than having to add diodes and relay? If yes what brand is it? Thanks! Ps: I'm using the stock remote lock if that helps.
