Ignition Timing On S2 Neo Engine

[stageaERIN]

Have searched forum but cant find it. Can anyone tell me how to check timing on a NEO engine...

Through my search i found out the series 1 has a small wire above the rear of the head where you connect your timing light to check timing but the S2 neo is different.

ive seen my mechanic hook that litttle light thing to the blue wire up the back of the engine, think its next to the white wire. if not the blue, then the white

from my experience and talking to a few mechanics, the rear wire method is not as accurate as: pulling off no.1 coil, putting an old fashioned spark plug lead from the coil to the spark plug and placing the timing light pick-up on the lead. A lot more time consuming though.

unplug the TPS aswell as it cancels the self learning . and do use the blue wire . if it says it in the r34 service manual i would use it . have to reset the ecu after you plug the TPS back in tho or the hicas light will come on because it relies on info from the TPS

It may be fine for Nissan mechanics with specialized timing lights, but for us with 'backyard' timing lights take care.

"specialized timing lights" i havent seen any decent brand ones for sale without an inductive pick up for ages

I've got part of the loop wire stripped bare, I just connect to that, works perfectly

ok cool. so the loop would be the blue wire at the back of the engine. and disconnect TPS.!

thanx guys

There were two loops at the back of my series I and both seemed to work the same.
