Greetings from Yorkshire.
I'm hoping someone can help me; this is a query concerning PSI Motorsport performance chips for the diesel engine.
My P38 is a DHSE, 1999 MY, chassis XA with a plastic inlet manifold. 222,000 miles.
I have two different PSI Motorsport chips (both used), and I'd like to fit one - but which one ? Professor Google only wants to sell me a new one. He offers no website for PSI Motorsport, so really I've drawn a blank. I'm hoping that the experience and knowledge within this Forum will come to the rescue. Here's my best shot at describing each one:
Chip 'A' : Tees into the Manifold Absolute Pressure's ELECTRICAL connection on the diesel filter head. Sticker on the outside of the chip reads: PB 20 00 11, SN 33754. Sticker on the inside reads: 2005 WK 16, VC:ww, FT:ww.
Chip 'B' : Tees into the MAP's VACUUM pipe between inlet manifold and switch on filter head. Sticker on the outside of the chip reads: 10 00 11 and 11565. Sticker on the inside reads: 2000 / 1201, VC:ww, FT:ww.
Probably not necessary to say, but both chips are tee-ed into the round plug/socket close to the Fuel Injection Pump, presumably to modify communications between the engine's ECU and the FIP.
Thanking you in advance.
