Is there a way to change/alter ignition advance on the 1.9 sohc? I think it needs MORE.

Thanks,

it CAN be done, but is a pain in the arse. Normally, ignition timing on this engine is controlled by the ecu.

What makes you think that the timing needs to be adjusted?

You can either do it through the software or by modifying the crank sensor.

I've also heard there is a high-octane jump wire some where in the car used for testing.

But yeah, what are you up to?

Well, it just stands to reason that the stock timing curve is designed for stock engines/loads/emissions, etc.

If you free up the intake (bigger MAF/TB)
Free up the exhaust (header/2.5/dual outs)
play with the cam timing....

You might need some more lead/base timing. The DOHC boys get all the thrills, I was hoping to join in.

Where would I find the "octane wire"?

I've the same question on my ZX2--'m running regular and NEVER HEAR A PING!! i GUESS that my engine is way retarded! moving the crank sensor sounds good! since I'm not into the software~~

On the second generation cars, there is an "Octane plug" hidden in the lower right of the console. If you remove the plug, the timing is retarded (yes, I know that's a hurting word) slightly.

Search "Octane Plug", and here's my nattering on the subject from a while ago in a thread (read from post #17 onward):

Trouble code 172

My 1992 wagon, 5 speed, no EGR is showing code 172, HO2S sensor fault - lean. The car is driving great, but the exhaust is a bit stinky even when the engine is warm. Mileage is down a little bit. I checked the spark plugs, and they are clean white - pinkish. I always burn the cheapest fuel I...

maf, tb, header and exhaust wont make a bit of difference on any requirement for timing, not on a 119CID engine.. the advance comes in pretty fast on the EDIS system. cant remember for sure but i think its 34*
