Not such a good mapping session tonight to be fair.
The damn VXR injectors just aren't up to it. End of.
The initial runs on the dyno show that the injectors were maxxed out. So as a fix, I put a 4 bar regulator on to try and eak enough fuelling out of them.
However, this has turned out to not be enough, as the duty cycle on the injectors is too high again now, suggesting that they simply aren't big enough for what is trying to be achieved.
I am a tad annoyed about it, as they clearly aren't the 470cc that they are listed as, but what can you do?
So, some bigger ones needed - probably going to go for some Bosch 440s, or Genesis 550s. Extra cost is a bummer - but hey ho.
Managed to eak the BHP up to 295 now, but fuelling towards the top end of the rev band is all to ****...
Anyone with some unwanted 550s let me know.....
