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

Oh dear.....

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

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

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 :y the thumbs up doesnt get a hat! haha!

Newer Vx models - Astra-H, Zafira-B, Veccy-C, Signum - use a different protocol called CAN.
In CAN, the nearest ECU to the device deals with it. For example, the bulb failure is not an ECU in itself - the rear brakelights are dealt with by the tailgate ECU. There is no central locking ECU - the BCM tells each door ECU to lock/unlock etc.
CANdi is the adapter that allows the Tech2 to join this network of ECUs.
As to diag tools for Vauxhalls under £100:
Generic ODBII for 2.2/2.6/3.2 (will do engine only).
Cheapo Tech2 if you have a laptop with COM port (flakey as hell, simple code reads and resets only).
Beyond that, you're looking at Opelscanner or whatever its called this week, around £400.
Nothing but a real Tech2 will give you anywhere near the functionality of a real Tech2 - £3k new.
-
And later Corsa C....which has a mix of CAN and ISO!
-
For OBDII cars only ..... 2.6 /3.2 ....
For engine/transmission code reading and EML resetting, with a small amount of live data reading, but NO reprogramming at all the Maxscan GS500 is a reasonable piece of kit, it has certainly done all I've wanted to do so far.
I wouldn't trust myself with anything as complex as a Tech2 without a fewe months trianing by TB or MarkDTM !!! Seems to me in the hands of an idiot ( me and/or stealers) it is either useless or dangerous !!!!
Maxscan GS 500 is around £80 for a GENUINE AutelTech one ... fake copies that don't have all the bits and don't work as well are cheaper on fleabay .. but I had to send it back ... then bought a "real" one .. :)

Do any of these eBay thingys read the 2.5 V6 '98 ?

The "My Naff Code Reader" stuff on ebay will go back to 1998, mine is a usb only system and works ok without a com port without the need for adapters etc

For under £100, cheapo tech2 is your only option - but for engine only, remember the free paperclip test ;)

for me tb it's only really the fault code reset that i'm interested in (so i can reset it and see which are current/saved codes
thanks for info

cheapo tech2 then, but you need a lappy with real com port, and accept the software is flakey

is the plug and play handheld stuff not ok?
can get one an a 10 pin aldl cable or whatever it is for 50 :(
-

the handheld sub £100 stuff is all obdii, thus as much use as a used condom smeared in dogshit to you.

exquisite explanation .... :y :y :y :y
;D ;D ;D ;D ;D ;D

So is "a condom smeared in dogshit" much use for my 3.2?
What can I do with one, given I have an OBDII car?
Which model is good?
How much roughly?
Where from?

I'm shocked :o ;)
I feel they get what they deserve in this case...if he group who owned the "My Naff Code Reader" stuff sold it for 100 quid, there sales would be considerably larger and it would not be worth hacking.

Generally not much more than the pedal trick for cheap handhelds, except you can reset engine codes.
If you have a decent fast laptop, a £25 elm based one from egay, and free software like www.scantool.net will allow limited live data. Can do engine only

I agree - if they priced it for the hobbyist it would sell. Instead, they are pricing towards garages, who are going to want a more generic system, thus tend to use the Snap-Off stuff etc.

Would this require an RS232 port? I don't have one of those on my laptop.

Had a play with a Snap off system the other day, Mrs gixers polo abs light on. It seemed to have a massive range of cars in its data base. A fair amount of live data too. Still couldnt reset e39 bmw self levelling suspension sensors tho. 2.500 of your English pounds and a 40 a month sub. Ffs!

Get a USB one. I think internally they use a usb to serial adapter, but you don't have the issues like you do with cheapo tech2.
Not sure if they work under vista, only tried xp

Cheers TB. What do I look for on eGay?
I did a search on eBay UK for elm obd2 and got a lsit of various stuff ranging across: 320, 322 & 323. I get the USB bit, but I'm not sure which of them I'd need.
http://shop.ebay.co.uk/?_from=R40&_trksid=m38.l1313&_nkw=elm+obd2&_sacat=See-All-Categories
- OBD2 ELM Diagnostic USB interface
- ELM323 Car Diagnostic Interface Reader Tool ELM 323
- ELM323 USB OBD2 EOBD Scantool Scanner Interface elm^323
- ELM323 OBD2 EOBD Scanner Interface Serial cable elm^323
- ELM320 OBD2 EOBD Scantool Interface Code Reader elm^320
- ELM322 OBD2 EOBD Scantool Interface Code Reader elm^322
Any chance of you posting a link to the right thing? Preferably being sold from in the UK too.

Can the maxscan do live data?
www.scantool.net can, and there are times that live data is essential.

A limited amount yes .... can't remember which PIDS it reads, I'll be able to check on Thursday for you ...
