SA I5 timing

[ELVIS]

SA 2.3. Runs a tad hot, fan comes on in heavy traffic tad to quickly, judders when just coming off over run and giving slight has as if in to high a gear, engine bay gets a tad hot, pinks a bit, isn't totally smooth.

Looked on forums and found this

Have found the five pin plug ok, BUT there is a factory style jumper that is bridging the terminals 2 and 4 , pushed into the OBD and its been in there a while.

On the engine lid there is a factory sticker that is partially torn but does say the five pin plug that has a jumper across pins 2 and 4 should be in place when timing is done and set to 6'.

Unless I am misunderstanding the situation, plug jumper in, set timing to 6' , remove plug.

I guess the way to check for sure is to put a strobe on it with jumper in and without and see what happens to timing.

What confuses me though is I put a post on one of the SA forums and was told to leave it in.

Syncromad replied on both and unless I have got the wrong end of the stick, his advice in the two threads contradicts. On Ian's the plug goes in to set timing, on my thread he says to leave it in all the time.

Spoke to Ian and he doesn't have a jumper on his, just a plain cap to keep poop out of the terminals but with no jumpers on when he drives his.

Removed the jumper tonight and it's cured all the afore mentioned symptoms.

Proper confused.

Can get pics tomorrow.

Anyone shed any light?

Symptoms cured so your premise must be correct. There arent many on syncro-sa with actual knowledge, Stuart is one of the few but anyone can make a mistake.
IIRC 2-4 bridge can also be used to retard the ignition for poor fuel, like the octane plugs fitted to late 80's GM cars.
Up to 2kOhm rings a bell.

PS the fan on the 2.6 is a little eager too, scares small children and old ladies in traffic

Hi chap, hope the man flu is on the way out

Think plan of attack is on Friday will strobe it with and without jumper and see what happens. Only runs on 97 as not many miles done in it so to hell with the expence

Booked into local long life franchise on Tuesday ( from what I can gather the quality varies helluva lot but mine has a very good rep and he has done a few Gti exhausts for me and his work is spot on). Have been quoted £350-400 from the 2-1 pipe ends just inform of drive shaft , big box then back out to tail pipe/back box.

Will let you know how I get on and cost if you're interested?

About 90% now thanks, clearing out the airbags so back to the graft, no excuses.

Always run it on Momentum 99 if I can get it, pinks on regular and the performance drop us noticeable if the timing is backed off. Mileage is better with higher octane too (timed to suit)

Had a longlife exhaust on mine for years!
