I decided to check my ignition timing today and found it to be about 27 degrees before top dead centre.:sweatdrop: Slackened off the 3 bolts securing the crank angle sensor and rotated it clockwise until I achieved 15 btc. My only worry is that I had to use all of the adjustment to get it.

The strobe I am using is a pickup type that I connect top the + and - respectively and the pickup to the looped wire at the power transistor unit.

I seem to remember reading that this method may give a false reading of up to 10 degrees error.:ohmy: Could anyone advise please?

Yeah best way is to use the spark plug type! Also the car needs to be warmed right up & if an auto I think it should be in N & there is a different reading for auto & manual I think one is 15 & one 25 ?

You have to put the ECU into "set timing mode" too. Have a read of the online manual on how to do it.

Erm.... never heard of that? where did you get that from?

Oops .... wrong car :oops:

The only thing the manual said to do was to rev it two or three times then let it idle

I thought Jeff was the manual !!:innocent:

OK, So in summery.

Am I getting a misleading setting from the method I have tried? I am worried about leaving it as is as it could be set as low as 4 to 5 deg' BTC.

Maybe I will get an extension made up so as to let me pick up from above the plug and below the coil pack?

Would someone clarify please?

Not had an Auto/Manual conversion has it?

No, It is as standard.

It has had a new complete bottom end including turbos though.

Still as standard mind. Could that make a difference?

No, sounds like you need a decent gun tho'(spark plug type) and if the Cas is way over at 15 degs could be the belt is slightly out when rebuilt.

Cheers Mantav8,:thumbup1: I will try and pick one up this week end and re check.

I will let you know what the difference is between the two as soon as I know.

I thought I would try something while I wait to pick up my new strobe. Warmed the 300 up to normal and double checked the timing as before.(induction pick up on the power transistor unit loop) as before I left the clamp closed. Same reading 15 deg' BTC.

 

Switched her off and re connected the same strobe again in the same way but this time I left the induction clamp open. reading 3 deg' BTC.:ohmy:

 

Tried this several times and the figures repeated each time.:confused1:

I decided to go with the settings found with the clamp left open and will double check once I have a different strobe gun.

 

Just out of interest, after setting the timing with the clamp open, I tried the set up with the clamp closed. reading 27 deg' BTC. hmmmmm

Ok quick tip to save buying another timing gun, the induction one you have should be capable of sensing the coil packs triggering, if the head of the clamp is small enough place it down the back of no1 spark plug and it should work just fine , if however the clamp head is quite large then they normally are screwed together, undo the screws and your left with the induction sensor on the end of the cable, this is now easy to place down the back of no1 coil pack, assuming all working with engine up to temp then 15btdc is what you need to set it at.( will post a photo of this if it helps tomorrow)

Many thanks JeffTT,:thumbup::thumbup: You are right, the head of the clamp is quite large, so I will have dismantle it and try it out tomorrow. and yes, it would be of help if you were able to post photo's. Thanks again for the advise, I really appreciate it.

 

By the way, What is the Zedworld Bash? and were is it?

Ok here is the pictures for for you, the first shows the timing gun and the sensor from the trigger clamp.

 

In the second one you can see where the sensor need to be placed, in pic three shows the sensor in a slightly different place, it my be trial and error on where best it picks up the signal, seems quite ok almost anywhere near the coil windings, pic four shows how it looks from further back.

 

Good luck

JeffTT, Many Thanks for going to the trouble to post pictures, Worked a treat. I owe you a pint or 3. :flowers:

Is it mandatory to attend the bash in a Z? The reason I ask is I am still welding up my arches, floor and sills etc'

Hopefully to have her ready for a full respray in the Summer.

Again, Thanks.:thumbup1:

Great news, been using that method for years, no problem not arriving in a Zed a good chance a few others will be too.

Crickey .... I was worried about a little palm sized rough patch I found on my car. It pales in comparison. Well done. Truly inspirational.
