right was having a look today to see whats up with car as thought i needed a chip as at high revs in 3rd plus the car seems to cut ont when flooring it revs drop to 0 or the car judders and usualy backfires and kicks out flames

i have a look at my ecu wjich is a z4 and looks like it has a chip in

 

the chip is probably why it is hitting fuel cut.

What boost is it hitting?

 

the boost gage fitted is a bit hit and miss sometimes 1.5 and ive seen it as high as 2.0

genraly i would say it hits the 1.5 mark

 

Thats way too high either way.

Are you sure the boost guage is plumbed in right?

 

i belive so i think its the chip, as ive only just got car a local garage gave it a look over and recommened i go to subaru specilist they know he took it for a spin and said it needs an ecu or a chip, he checked rest of car and said its fine.

would you say its the chip cauing the problems? if so what would you suggest?

 

taking the chip out?

 

yea but wont a need a replacment as got fmi,decat ect

thanks

 

It really needs mapping for what is one the car rather than a random chip which may or may not be safe.

It will not work with removing the chip as it will need resistor J1 rejoining.
