Yeah the xdf is 104 I was using the 102 adx but changing to the104 adx just made it read lower vlt304 wrote the 104 bin to my nvram so I changed the xdf to suit I just forgot to change the adx aswell but that doesnt explain the lower reading

[vlt304]

how much lower?

sorry i meant to post a pic but i was out n ran out of data but it was down around 40 kpa but im home now i just had the car running to check it out n see if it was fixed and the data tracing is fixed and all sorted now thank you all for the help i appreciate it but the car still runs like a dog sounds like its a cylinder or two down it seems that pulling the passanger side bank injectors off doesnt make much of a change so it would seem either the injectors arent firing properly or not at all witch is strange seeing how rich it runs but never the less im going to try n order a new set of injectors this week though i dont think they are at fault i just need to upgrade them and i might look at getting another 424 n see if it helps just incase theres something wrong with the injector driver etc or perhaps i did something wrong while putting the write wire on or something i can post up the log of it if it would help i got while it was just running i dont know if it would be any help though

It sounds like they might be stuck open. Ive heard of that before and heard tapping them on something solid to loosen them up can help if they are just stuck rather than broken.

[vt3.8lt]

thats quiet likely is there any way to check that ?

[vlt304]

I am happy to put them in the tester for you..how big are they you may need to enable single fire mode if the pulse width is too small they wont open or may dribble at idle.

[vt3.8lt]

there only small 300cc ill see if single fire mode helps if its not already on i dont think there dribbling at idle as it misfires through the entire rev range

[vlt304]

do you have a noid light or led test light to see if they have switching when it is running?

[vt3.8lt]

i only have a multi metre at the moment i dont think it will help with that as far as i know

Are the injector tables set up to suit? That makes a difference I've been there first hand.
