i went to time my sr the other day i hooked up the inductive timing light to the loop on the coil pack harness and ran the positive and negative to the battery went to time it and i noticed i was no where near any of the marks it was off to the far right so i tried to adjust it and i still couldnt get it anywhere near the timing marks so i pulled the valve cover and set the cas to stock by lining up the orange dot with the indent on the cas i tried it again car ran like crap and the timing was still no where near the marks what could be causing this am i suppose to unplug something in order for it to line up right?

you hooked up the inductive cable to the coil pack wire harness? Would that even work..?thought you could only use that on distributer cables

There was a huge thread about using a timing light with the SR. Expensive ones have trouble getting signal from the distributor less ignition and read way off, i bet if you tried to time to 25deg instead of 15deg it would run perfect. The cheap ones seem to work tho. But either way what i would is pull the valve cover, line up the CAS and line up the timing marks on the chain and the crank. Just set it mechanically. That way you know your dead on.

Make sure your do everything that this site tell you to do.

You can't line up the CAS, you have to line up the chain, and the crank to. IF you did all of this, then you might be a off a tooth on the chain.

Then if your still having a problem, check your knock and O2 sensors. sometimes when you have a bad O2 the ECu will pull timing to avoid knock. If you got the money replace all your o2 sensors and get a new knock sensor to.

i set it to the second mark from the left tdc and lined it up i actually used that write up when i did it last week, ran like junk it seems like someone put their own timing mark on the pulley its way off to the right and if i put it there it runs pretty good but still misses a bit at idle i was getting a knock code but i replaced the sensor and cleared it and that was before i timed it i got this emance real time ecu viewer but i cant get it to work right along with his garbage tune

The trick is to use a spark plug wire from the coil to the plug. The light will pick it up fine from that.

The mod has the right idea. Also i almost forgot then sometimes you have to put the engine in "timing mode".

I have never done it but i have read about it.

It sounds stupid but it's what it says to do in the FSM.

rev the car to 2,000 rpm for 2 minutes. Turn the car off unplug the TPS then rev the car to 3,000rpm 3 times and time as normal.

sounds pretty crazy is that from the s14 fsm? ill give it a try and see if that solves the problem i also got this emance real time ecu reader im trying to get it to work but im sure if i do get it working wouldnt i be able to view timing and set it while i view it from my computer?
