Is that the correct filter ?

[Bargi]

what is it in the logs what shows it's maxing out?

Might have to look at mine!

[CHILL Gone DUTCH]

The AFR went lean followed by the power dropping before limiter To be 100% I need a fuel pressure gauge but figured just do it anyway not worth the risk

Your probably running more boost than me bargi which means your pump will run out of steam at lower revs

[Bargi]

This was done before I'd fixed the charge cooler pump relay which is why the IATs are so high. 

Even the 4th run at 99 degrees AFR was well below 11 so plenty of fuel there.

When I had the CS map I'd maxed out the Turbo injectors and running lean produced more power.

Once I'd upgraded to the Blue VXR injectors I actually lost 5bhp

 

Below is running the pulley that came with the Harrop.

Your AFR looks like it's going lean around 5000-6500 But that's the least of your problems what's happening with your knock

It looks like it's retarding a lot

[CHILL Gone DUTCH]

Can you send me a few of your files ??

[CHILL Gone DUTCH]

If your still on blue VXR injectors I don't think you will have issue with pump

[CHILL Gone DUTCH]

for bargi

 

[CHILL Gone DUTCH]

ive sent you a pm bargi

[Bargi]

It's on the larger Siemens injectors, the VXR injectors were the old M62/CS days. 

 

The leanest it's running is 11.9. In the software the target AFR is 11.8

Quick google and that also seems fine for boosted engine.

 

Towards the top end it runs really rich which I'm assuming is because the IATs are so high and ECU starts dumping lots more fuel. That would seem to indicate the injectors and fuel system is up to the job.

yes the graph ma[color=rgb(40,40,40);font-family:helvetica, arial, sans-serif;]de it look worse than it is,[/color]

[color=rgb(40,40,40);font-family:helvetica, arial, sans-serif;]it changes up to   1.0 in software when inlet temps are that high so that looks normal,[/color]

but ignition looks very low

i think the ignition shoul[color=rgb(40,40,40);font-family:helvetica, arial, sans-serif;]d be a lot higher[/color]

[CHILL Gone DUTCH]

pme[color=rgb(40,40,40);font-family:helvetica, arial, sans-serif;]d you a file to try bargi[/color]
