Nissan 200SX Club - South Africa

Can someone explain please, myself and Freddy has the same problem now, our timing was right, on the dot, now when I check mine it shows the timing is heavely advanced but I did't touch my timing.

Freddies car does the same, he started playing with his timing, he sets it right, when he gets back after a ride he checks it again and it's way out.

Any ideas?

Ok, but how does the car feel?? does she go better or is she slugish or the same?? are you guys using the same timing light?? or seprate ones??

We have different ones but my new on shows the same as his older one, the car feels the same to me because as I said I didn't touch my timing, I just tested it and it was advanced alot according to my light.

Freddy went according to his light, he advanced it to say 20 dgs then when he checked it again after a run it was heavily advanced. He then retarts it back to 20dgs then the car would jerk on higher revs obviosly because of the timing being to slow now, then he advances again, jerkings gone but sometimes pings, retarts the timing again, then it's shows heavy retarted after a drive.

WOW, sorry i cant even start to tell you what is wrong unless im there and can check it out, but as far as i know the ecu cant make timing changes but then again i can be wrong?? sorry i have no idea what it could be?

The ECU does make timing changes. I would suggest that after you make your timing changes, take out the car battery to reset the ECU. Then reconnect it so that it can go into learning mode. If the ECU detects knocking, it will retard the timing.

WOW, just shows you your never too old to learn something new!!

I initially said on the forum that I feel the ecu must be fooled in a way.I just did not know how. Will
give this one a try very soon.

thats not going to do anything, the ECU isnt self learning. What was the car idleing at after the run?

Perhaps the key on your cam is worn causing the 'floating' timing, or worse the key on your crank could be worn. I doubt it is this, but it is known to happen.

Oh ya, you did check your timing initially when the engine was warm didnt you

idleing was perfect. Yes engine warmed up properly.

leave it like this and view it like a surprise lucky-packet
