hey guys I'm posting on behalf of a mate who isn't on the forum but I'll keep hounding him to get here.
He has a 2011 s40 T5R
he's recently done some upgrades.
3" turbo back system with hi flow cat
upgraded cbv
snaab intake pipes
bsr pod filter box
and a Hilton 2+ tune
ever since the tune he's been having consistent issues.
he's spoken to Hilton about it numerous times and was given an updated tune which didn't help and is currently waiting for another reply but Hilton is ghosting him and claiming it's not tune related.
so without the tune installed the car runs great but throws 02 sensor codes which is to be expected with his exhaust setup, the car doesn't go into limp mode etc just throws the CEL.
with the tune installed it keeps going into limp mode.
he has Vida and has pulled the codes and it's coming back faulty accelerator pedal.
this went on for awhile, he kept clearing the codes till eventually the pedal stopped working completely.
it was taken to his mechanic glt in qld and they replaced the pedal and cleaned up the connectors and wiring etc
it was good for a few days then bam limp mode again and same thing faulty accelerator pedal.
if he flashes the car back to stock it's fine, doesn't throw accelerator pedal codes or go into limp mode only the 02 sensor codes
flash the tune back on and limp mode.
Hilton has said he's confused what's going on cause his tune has nothing to do with the accelerator pedal etc
he just changes ignition timing and fuelling tables etc etc.
we have no idea what's going on but it's starting to get ridiculous, he spent big money on the tune and it's worthless.
those brief moments the car runs on the tune before going into limp mode is fantastic, he said it is a huge improvement and goes bloody hard but it's super short lived before the car spazzes out and goes into reduced engine performance mode.
does anyone have any ideas
or point us in a direction to look.
I don't know new cars at all so I'm not alot of help and my mate doesn't really know anything but is learning real fast haha
it's been taken to glt car center and they are lost and said it's abit over their head and what they do
I've uploaded the Vida page with the fault codes, he has endless screen shots comparing the car on tune and stock if they are of any use to anyone
