Timing and base idle adjustment on a manual conversion

Just completed my manual conversion and boy did I enjoy the run home,

as short a run as it was; it's the most fun I've had in my zed in a long time!

 

So,

 

Before leaving the garage I ran a quick consult.

 

Timing on conzult was siting at 5 but then remembering the neutral switch I wired to the ecu from the gear box I pushed the clutch down and shifted her into gear and timing shot to 15.

 

Regarding timing should the base idle be adjusted at an idle of 5 in neutral or should I be getting somebody to hold it in gear while I adjust it.

 

I'm only guessing 15 is the correct timing so can anyone confirm this too.

 

 

Cheers

Ok what I think is causing you a problem is the later year of your car, the later cas unit and ecu has a different ignition map that does show 5 deg tdc readings when up to temp, sound like the neutral switch is fine and working correctly so no worries there.

What to do is to is to check the timing when the engine is cold, be patient and as the engine warms up slowly when its around 60c to 65c the timing should be around the 15 deg mark then confirm this with a timing light, if it needs adjusting then be quick as once warmed up it will go to the sub map of 5 deg tdc

 

If you have a full ConZult system you can set the engine temp to 65c deg and make the adjustments at ease then.

 

The later engines had a few things removed by Nissan like the egr valve and the pvr system etc so the altered mapping / timing was part of this.

 

Hope that helps
