so at a later stage if I wanted to change to a 30lb injector.

24/30*125 gives me 100 BPC

[Holden202T]

or 19/30 * 158 = 100

Yep done that too .

Seems pretty easy now lol.

Thanks for the help guys is very much appreciated.

I'll throw couple pics up in the appropriate thread once the engines back in the car.

You do need to also consider the injector opening times change with different injectors. I dont know what the items are called in TC though.

In OSE12P the item is called "Injector - Injector Bias vs Battery Voltage". Holden202T posted some info here .. http://pcmhacking.net/forums/viewtopic. ... ias#p32885

There is some more info here http://pcmhacking.net/forums/viewtopic.php?f=28&t=3113

Will read up on that and have a look in TC. I know there is a spot to change just can't remember of top of my head what it's called.

Thanks

Got it fired up BUT is running rich and I mean foul a set of plugs within 20 seconds rich.

Fuel pressure is set at 30psi.

I have a VS tune that greenfoam made up for me a couple years ago for the 775 injectors and I have cross referenced all the settings in that tune to mine and all injector related stuff is identical although the BPC was still left at 158.

Now that I have changed the manifold the VE chart wouldnt need changing that much? I expected to need to change it a little but dont expect the VE to now be out enough to foul plugs straight up.

While the engine was out I put a Innovate wide band AF gauge on and its sitting on 7.4 at idle. I have never used the gauge before but assume thats about right by how rich it is lol.

Should I just pull a heap of VE out and see what happens. Don't really want to change the injector off set when I have ran with the same setting and good results before??

Put the car straight into diagnostic mode and still ran very rich. Like someone has a smoke machine at the back of the car lol.

My current bin but my BPC is set at 125
