Excellent. Glad it arrived and I wasn't having a total brain fart with those instructions. Fingers crossed it helps point you in the right direction. I'm guessing you'll probably have to use the measuring blocks options to log exactly what sensors are reading what, given the lack of fault codes.

that sounds like gobbled de goop so what do i want to measure? 1st lambda mV?

asking for an activation code

[techieboy]

hmmmmm, don't remember it ever asking me for one....

[techieboy]

There's a file called OP-Com Activation.pdf in the zip file that you downloaded that talks you through getting past that. Still don't remember doing that though.

All sorted Well I think I see an error. I only have 1 O2 sensor However opcom is thinking I have sensor 2 plugged in instead of sensor 1, it's reading 451 mV Air fuel ratio is lean O2 sensor loop open My afr guage is showing 12.4

Joe, try here: http://www.cocopops.net/opcom.zip That's the version I have (Doesn't need activating afaik)

Are you running an aftermarket wideband sensor with a secondary narrow band output to the ECU (to run the gauge and ECU at the same time)?

Odds on thats setup wrong.

OR the classic of not plugging the Lambda back in the Lambda plug

[The Batman]

nope not running anything like that, my wideband doesnt touch the ecu in anyway shape or form think i have a duff lambda sensor so will change this first.

[vocky]

you should get 'Astra-Joe' to have a look, he is a genius with 2.2 Astras

[The Batman]

and i bring you... FIRE dadadarrr pfft, new o2 sensor ordered

Ah, good you got it working.

And it clearly indicates something is wrong with the O2 feedback. (Do you still have a post cat O2 sensors fitted in your exhaust and wired in?)
I'm not familiar with your or the Z20LET wirings, but is it anyway possible to plug the O2 sensor(s) in the wrong connector? On the 2,2 the connectors are completely different.

hmmm i will look friday, although i think i only have one working tomorrow day and night so that rules that out. friday/saturday/sunday will get it sorted and to the bottom of this annoying thing.

[vocky]

Joe only has one lambda plug in his modified engine loom - for the mixture lambda

[slindborg]

Does the VXT not need the postcat feedback?

[Exmantaa]

Probably all post cat O2 fault codes are ignored in his software version. Only strange that Opcom sees his mixture O2 as #2 sensor, but maybe that is "normal" for the Z20LET ecu codes. But anyhow, his O2 read-outs are not normal so he's working on that. @Joe; what is the conclusion now on the blowing manifold??
