Timing Adjustment

[jztt]

Hey guy's what's the procedure for setting the timing on our 240's.
Is there a check connector you have to short or do you just adjust it and lock it down. Also what is the timing set at?
Thanks
Doug

disconnect TPS
+ or - 20 degrees is proper timing

Dousan sniffs a lot of household products.

The 240sx.org says:

"Fully warm up the engine. Shut engine off. Disconnect the TPS harness connector. It's located on the passenger's side of the engine just above the throttle assembly.

Attach timing light. Start engine and set timing to 20 degrees BTDC. Check the idle speed. It should read 650 RPM; If not, adjust the idle screw until you get 650 RPM. The idle screw is located on the passenger's side of the engine near the firewall below the intake manifold. Stop the engine. Reconnect the TPS harness connector. Start engine. The idle speed should now be 700 RPM."

Isn't it good to have it set at 24* BTDC to let a little more air/fuel into the combustion chamber.:rawk:

Depends on the fuel you're using and the environment you are in. Too advanced timing could cause detonation.
