ok, fitted a greddy fcd today and a fuel pump.

Do i need to fit a new fuel regulator to go with the pump? and/or adjust the pressure?

Im still getting fuel cuts tho.

What boost should i run with the greddy fcd set at 4.3v ?

 

 

mods are

full stan/exhaust inc de cats

blitz dual sbc

walbro pump

greddy fcd

apexi filter

Dump valve

Also the od light is now flashing.

I did notice another box next to the ecu and the wires had been scotch locked in to the loom, could this be the speedo de-limiter?

Im thinking a wire mite be loose now ?

mate i had same problem when i disturbed mine has the little box got a blue sticker on it?

 

i just replaced it with one from ebay and problem went away, you could try removing the scotch locks and solder the wires.

 

mine used to gimme engine warning light as well when over 80 leptons

 

hope this helps

Once you have you fuel cut problem dealt with, you can up the boost to 1.2 bar (17.5psi) this is known to be the maximum 'safe' limit for the j-spec turbo's. However you will also need to change your spark plugs. Have a read of this http://www.mkivsupra.net/vbb/showthread.php?t=94705 and to help you on the spark plug front have a look here http://www.mkivsupra.net/vbb/showthread.php?t=41927
