Thanks guys, I mean no disrespect to anyone in the questions i ask. The way i see it is that we are all here to learn.immortality wrote:Ignore generic OBD2 codes as they don't apply to the V6 engines which still uses ALDL comms protocols.
With respect immortality, then I would have to question why my purchased software for the Vx v6 that diagnosed the error, then refers to the error as "P0151 = Left side O2 Rich." if the generic codes are not valid ? Or are you meaning the codes aren't actually the same for the ALDL and the software is wrong in what the error it is stating?
I can see as you agree also immortality, that if the fuel pressure is changed significantly from the specs of the manufacturers ratings that there could be altered values of cc/min. Though the differences between item 2 & 3 which both have 3.5Bar as the rated fuel pressure needed, give very different values of nearly 70cc/min and 7.19 lbs/hr more fuel being injected in to the cylinder. Item 1 & 2 are 3.0 and 3.5 Bar with only 0.2cc/min variant. So I don't see there being a significance to the pressures there.
From previous bench testing of injectors some time ago, fuel pressure around the 35-45psi didn't even make anywhere the significant changes to volume output like items 2 & 3 state. With the difference of 7.5 psi between the 3 and 3.5Bar, I would suggest that it too wouldn't matter to the specs given by the manufacturer. Fuel types could though, given that Bosch state themselves they don't use petrol when they test the injectors for getting the specs they state. but that would be also minimal I would think.
delcowzzid, I respect all on here and who have done the work and I acknowledge that there would be very many hours and many people dedicated and working to have got these things to where the values are. But it seems they may have based the values on that which aren't the same as the ones from Bosch themselves state. I am yet to bench test my injectors for their actual specs, but all currently fitted are genuine Bosch ones and of the same labeled part number. I am suspecting that there are going to be differences in them but unlikely to an amount of around 70cc/min.
I tried the china ones a few years back and had 2 of 6 fail for various reasons on install, so they all got thrown out at the same time. A learning curve with a cost.
The1, so could it be possible then that on some series of the Vx cars they altered the injectors to the 150cc/min and the ECU accordingly to cater for the lower injector flow rates?The1 wrote:Holden did use the same base injector rate between VS - VY. though the injectors flow different YES. I think it was lazy, because after VS they added the injector rate table, they just tuned that, instead of altering it then tuning it.
At this stage I just can't confirm if the current ones are performing correctly or even with all of equal and identical specs of say 150cc/min or >220cc/min. So in the interim until i make another injector tester, I will ponder the logic of the whole situation.
Thanks guys.I will keep you all posted as I find more results.
