I had a mate use his genuine Tech 2 machine on another mates Vectra to diagnose a problem. We solved the problem (airflow meter) but the tickover was low which he upped using the Tech 2 machine! I didn't realise that you could do that sort of thing with the Tech 2 machines.

I wonder, a;what can you do with one of these machines and b; I know they're expensive but how much and how good are the clone equivalents?

Real Tech 2 expensive - ask TB
Clone Tech 2 - cheap <£30 - can read most codes and reset a lot of codes - useful but thats it.

[Marks DTM Calib]

Not much a real Tech2 cant do....and many things it can do including things you shouldn't.....an example being changing the factory default setting for engine idle!

Why did he up it...was it not idling at the ECU request speed?

[Humpy]

Mark,

It didn't show any codes but warned that the tickover was low. Is that not good then? My buddy (who is a Vauxhall trained mechanic) says that the ECU's take a few miles to reset these type of things themselves which is why he did it manually (well, manually via the Tech2!)

I see Gunson do a tester for a couple of hundred £ is that any good? Do any of these clones have the funtionality (or near) of the full blown Tech2's?

Edit: The Tech2 warned that the tickover was less than recommended (default?) so he set it to the default 900rpm. Perhaps someone had adjusted it previously to the lower setting? I take it then that you can't alter the tickover manualy anymore?

900rpm seems high idle for a V6 - 500-650rpm (dependant whether a/c compressor running) normal for these engines!

Oh dear.....

[Humpy]

Dbug,

It's a 2L petrol not a V6 if that makes a difference to the tickover.

TheBoy,

"Oh dear" :-? Now you've got me worried

Whoops - sorry assumed it was your motor - should have read original post properly!

Yes....ow dear!

The base idle settings are a constant programmed at the factory, they do not adjust, need adjusting or should be adjusted.

The ECU looks at the real engine rpm (from the crank sensor) and compares it to that of the target (factory programmed setting)....it then adjusts the idle valve (very quickly) to raise or lower the rpm until the factory value is achieved.

Sounds like a case of a little knowledge.........

A guy on ebay sells them for £2,500 - that's about 10 Omega's.

Humpy

Yeah, expect to pay just shy of £3k for one brand new, or around half that for 2nd hand.  Add around £300-500 for CANdi if required.

[Humpy]

Ok guys, thanks for all the replies. I see I've now got Santa hats on my smilies, must be the time of year

The "My Naff Code Reader" I bought a while back can programme keyfobs, immobiliser and the airbag system and for the sake of the £20 I paid was well worth it from ebay.

The only system it point-blank refuses to work with is the climate control system

Sounds like the one with the illegal software

what is CANdi?

also..TB do you mind having a nosey on ebay at cheapo tech2 units for under 100 pounds just to see what you think would be the best one for us that want a cheapo solution to tech2 with most of the vital abilitys?
if you can then thats great, doesnt matter if you cant
thanks anyway  the thumbs up doesnt get a hat! haha!
