PPP Chip and Cams

[physicsfool]

All looked/turned ok

[Yoof]

Cam bearing caps clean and in the correct order?

[physicsfool]

yeah and tightened to 6nm followed by a 90* turn. covered the followers and tappets in special grease

[physicsfool]

So I resolved the issue... Popped the original chip back in and she roared into life

Not quite sure how the chip became damaged but you can see a burn mark on the centre if it

[Andy]

Looks like you've popped it in the wrong way round, usually damages part of the memory which is why it won't be running properly. I can do you a cheap replacement, but am away at the moment - drop us an email.

[physicsfool]

Ah smashing, thanks for that!

Thanks to Andy I now have a fresh PPP chip in. Before i swapped cams and chips over car idle was a tad high 1200rpm but nothing ridiculous.

Since swapping everything over the idle has become rough/high when the car gets warm. When i turn it on, its at about 1100 rpm but once the car gets warm it rises to 1800rpm once i apply the clutch. The idle will sometimes drop if i apply the clutch and 1st gear a touch. but mostly it rises back to 1800.

i spent the day going over the diagnostic guide on here, only thing that confuses me is the co pot reading, when i put the multimeter to points 1 and 3 the cars rev drop right down (like its about to stall) and reads a really small resistance. 

when i remove the blue temp sensor at running temp the revs rise, however i realise i didnt set the ignition timing when it was in service mode, will this make much of a difference?

and my cam timing is still half a tooth out.

Thanks

[Andy]

It's essential to set ignition timing in service mode. Do that, and set the CO pot resistance to circa 550ohms as a starting point.

[physicsfool]

How do i adjust the CO pot resistance?

[Etches]

Measure across pins 1 and 3 after you take the loom clip off, I set mine to 550ohms before it went on a mates exhaust gas analyser. Think he riched it up after changing the blue temp, melted fuel pump relay and lambda

[physicsfool]

Cheers for that lad, I will set up the timing and resistance and holla back

[physicsfool]

So I timed it up in service mode. Sounds much better.

When I checked the resistance in the CO pot it was 850, dropped that to 550, although doesn't feel like it's idling quite as smoothly. Should I try increasing to 600/650?

[Yoof]

What's your idle speed? Idle switch engaged?

[physicsfool]

Before I adjusted the CO pot it was 1000rpm. Now it's up to about 1100rpm.

[Yoof]

Too high - adjust it down, is the idle switch engaging too?
