Hi mark

we can set the bluefin to the previous stage 1 file to prove this if you require, please let me know you bluefin serial number

I didn’t get the standard cars logs with your last email

The reason why the car will underperform with the modified map loaded is because the car runs a higher boost pressure with the  mod map, this in turn requires a higher volume of fuel which the pump is struggling to maintain.

Regards

Dave


is this correct could this be the issue? or are they just trying to talk there way out of the situation?

rich83:
SaintSteve runs Stage 2 on his ED30 with a standard fuel pump... can't see it being an issue personally!

ktlstar:
Maybe the pump is dying ?

Have a go with stage 1 and see the difference ?

liver:
yeah they are suggesting its a problem with my fuel pump of some sort. Ive checked the car for fault codes and nothing comes up.

Im gonna log stage 1 tonight to see if the problem is there too, if it is then there must be a fault if not i dont think they can argue its the car at fault.

how can i determine if the fuel pump is on its way out or has a problem?

According to your own logs with the 'map on' you have a fuel cut


When did you last change your fuel filter? I would also log block 103 for the low-side feed pressure from the tank. It should be around 5 bar.
