Thread: How to: Adjusting Ignition Timing

nice write up dude

is it the same for a hiport??

Should be fairly similar

Question: This has bothered me for years.

Sometimes when I get into timing mode, with the TPS unplugged for the first ten seconds, the crank marks will be placed appropriately. Then, the idle jumps a little higher and the timing marks advance all by themselves to an (estimated) 25* of timing and it will sit there for sometimes two minutes, sometimes five before it will settle back down.

The only way I can get the car to stop "self-advancing" is to retard it back to 13-15 degrees, and slowly turn the distributor almost one or two degrees at a time to get a PROPER reading.

This does not have anything to do with a lack of consult. The timing mode is definitely engaged.

I checked it right after I drove earlier today, and for the first ten seconds, the timing mark was right on 20* for about ten seconds and then it jumps up higher.

I tried messing with the IACV idle screw and it did nothing so I returned it back to the setting I found it at.

Why does it do this?

Am I the only one that has experience this? I know I am not crazy...

Flaky CLT sensor/wiring could cause this.

This? G Spec Performance - Coolant Temp Sensor, 2.0 (for ECU)

Yes, but it could just be the wiring/connection. The connectors are prone to corrosion.

does this still work the same way on a ve???

and is the timing mode rain dance nessacary with a calum ecu???

Should be and calum ECU is no different then regular ecu. Now if you have Nissan Data Scan, you can put it into timing mode by a click of a button.

hmm...click of a buttone sounds easier....where can i get it!
