I thought i would give this a go for a bit of fun when i go to my gf's house with a whole pack of v8's that live over the road.
Im a little unsure on what to do...
Steps 1, 2 and 3 i can do (is it saying i should hear lumpy idle now?)
Where it says to turn the car off and dial back the crank angle sensor, is that listed under 'cranking'?
I think the rest is pretty straight forward after that.
Cheers
1. Turn car ON
2. SETTING, IGN/INJ
3. Press DOWN 1 time
If you observe lumpy idle then note the number ie: -1 If you don't observe lumpy idle, press DOWN again. Keep repeating until you get lumpy idle, don't go past -3 or -4 it's too much. Now with that number in mind do the following
1. Turn car OFF
2. Dial back the Crank Angle Sensor whatever number you had in IGN/INJ Adjust, so if you had -2 dial it back 2 deg
3. Turn car to ACC
4. Edit the IGN map and shift every cell UP whatever number you used in #2. So if it was -2 then add 2deg timing to every IGN cell on the map
3. Turn car ON
4. Observe lumpy idle
