Mamba can you please confirm that VsV6engineandtrans1.5tp5.adx is correct as the data isn't making sense to me either there are flags changing the shouldn't be.

yeah VL400 and i had similar issues, make sure you are using vs v6 engine and trans v1.6-tp5.adx its got all the error code stuff fixed properly and do another log for us so we can see what the go is .... preferably with the temp over 80 degrees please

[Holden202T]

ok we've just realised v1.6 is not on the net yet .... i'll blame Jayme for that

its now been uploaded and can be found here

if your not using wideband on your car then just get the normal one ..... if you want wideband then use the wideband one obviously ... they are the same other than wideband mods to injector voltage line monitor!

[VL400]

And 1.6 has been superceeded by 1.07! Fixed all the engine flags up so they all make sense now

Just confirming that VsV6engineandtrans1.5tp5.adx is the adx file is being used...I have updated the adx to 1.7 (thankyou!!) and will log more info with a hotter engine...is of concern that a panel of experts are finding that the car is performing badly....are both sensors shot ?? .... thanks for all the feedback guys...much appreciated ....and to answer your question holden202, the car doesn't handle acceleration well at all...

yeah i didn't think so, feels like you have to push the pedal more to get it to go ?

one o2 sensor seems ok but the other one doesn't ....

i would suggest swapping the sensors side to side if you can, if the flat line your seeing follows the sensor than that pretty much tells you that the sensor is the problem, but if it stays on the side it was on originally then its most likely and earth or wiring issue.

other than that the leaness on acceleration is very odd, i've never seen anything command 15:1 afr's on acceleration ... might be worth removing the battery power from the pcm (or disconnect the pcm) for 20 minutes to clear all the memory etc and see if that makes a difference.... i don't really think its a fuel pump issue or anything cause it would be commanding 14.7 etc but the fact its commanding 15's or leaner is very strange, like something has been modified or corrupted....

if you can, get the latest flash tool and suck just the cal out of the pcm and post it up here ... may give us some leads to work through.

Thats exactly right..my foot can sometimes be flat against the floorboard to get a response .....the 0 - 60kmhr in 15 minutes becomes all too real.... ran it around a lot today to warm her up and got the attached log...shows that the one o2 sensor is in trouble...still appears lean....let me know what you think...the dashboard (1.7 normal-not wideband used) worked very well with even more info (thanks Jayme!! )...originally loaded without checking the rs232 box but the dash connection flashed red immediately to let me know it was incorrect...very helpful...thanks for the assistance

[Holden202T]

ok straight away theres a DTC 13 - NO O2 Sensor Signal

i'd be checking your o2 sensor wiring, if there both hooked up and look all normal then i'd be trying unplugging one at a time and see what it does on the laptop .... im wondering if one of them is not there at all and thats the one thats flat lining ....

i think you really need to get both o2 sensors working and reading properly before you can do too much more diagnosis of whats causing what.

[Mamba]

Both o2 sensors now replaced ...I think the connecting wires have shortened!!...unfortunately, while fixing one problem, several others have been identified ...the car will be out of action for a while ....
