Where Do I Hook Timing Gun Up To 25?

[Gamatron]

Hey all, I got a rb25det and want to retard the timing to 14 degrees, but before I do this I need to know where I can hook the gun to, as I checked it today and it said 17 degrees.

So if anyone can explain or show me a pic where an accurate place is to clip the gun into and if 14 degrees sounds sensible at 13 pounds?

cheers :lol:

There is a loop of wire near the back of the engine on the ignition wiring loom, although you can pick up stray signals when hooked up here. I find the best way is to take the coil off no.1 spark plug, place a plug lead from the spark to the coil, and put the pickup on this. You get a much better signal from an HT lead than trying to pickup the signal from the LT side of the circuit.

Also remember to have the engine warmed up and throttle position sensor unplugged to ensure idle is at 650rpm and the ecu is at static base timing.

i'm curious why you would want to retard the ignition and lose power? Are you getting detonation? Ignition timing should be 15deg +/- 2deg so 17deg is within factory specifications.

Cheers,

<{POST_SNAPBACK}>

detonation is the problem, ive had the problem before and fixed it with ngk.7 iridums but now its coming back?

because it is getting colder - more boost

or its to advanced

AFM shouldnt max out at under a bar

a mate told me iridum plugs r no good for high boost --- 12psi and up is this true?

what is the problem>>>>>
