WUR
I disassembled my 108 and a 054 WUR. The only difference I could see was that the bimetal heater had different coloured wires and the springs that control enrichment were of different pressures. Otherwise, everything else including the vacuum chamber was the same.
DAVID PRALL, Thanks for your info and feedback. Robert Bosch Germany have just replied to my query and the difference between the 108 and the new 116 is a built-in thermo time switch on the 116. They have stopped production of the 108.
BTW, when I installed a 034 to my engine, my top end acceleration was great but the mid-range had a 'hole' in it. Fuel enrichment for the K-Jetronic has alot of adjustments to it, if you can maintain reliability to your mods!!! |

Without checking the fuel pressures it will be only a guess, but it sounds like the warm up regulator is not working or you are not getting power to the terminals to allow it to warm up and change the counterbalance pressure in the fuel distributor. |

Now for my really strange FI problem...
82 euro 308- works great with no load, revs up fine, put it in gear and a load, it is super rich and bogs- won't take the fuel. I have backed the 3mm allen screw out CCW but this still doesn't help. I know it is in the FI because I had a driver in the car while I was sitting in the trunk adjusting it. I was able to pull up slightly on the FI arm/flap while it was bogging and it cleaned right up and away we went. With the WU reg, cold start and air bypass disconnected electrically, the same happens.
Help?...
Thanks
Erik

Yes, the plumbing configurations are all different. But, so also are the functional specifications. My references (Bosch product guides) don't show either of those p/n's (*034, *054) as ever being Ferrari applications. In fact *034 is for an Audi 5000 ('78-'80), and *054 is for a Porsche 911 ('76 & '78-'79). Based on that, I would be skeptical of your distributor's advice. You may want to call Bosch directly (they have an 800 number for technical assistance) and confirm this. If it were me, I would only replace the part with one which has the same Bosch number, but if your source has cheap prices, you may want to experiment with the others.
After all, a Ferrari doesn't know that it isn't an Audi or a Porsche!!
Good luck. |

Tks. guys for the information.
I have been offered alternative items 0 438 140 034 or 0 438 140 054 locally in Singapore.
The Bosch distributor here says that the WUR are all similar and the different part numbers refer to the number and type of vacuum fittings or fuel line connectors integrated into the WUR. Does this make any sense to any of you? |

CTK:
Bosch 0 438 140 083 is for the US version. If your car is indeed a Euro model, you do need the 0 438 140 108 (which has also been superceded by 0 438 140 116.
At any rate, I have a *108 --- the price is US$275 (plus shipping). you can contact me at [email protected] if you are interested.
Cheers,

try part number 0 438 140 083, that's the part number from my Bosch book for the warm up for the 85 gtsi |

Go to your local Porsche or MB parts distributor. You could also try the dealers in the Waterloo Centre, Waterloo St. of Belconnen, near Raffles.
They will source the part for you locally without any problems. |

Hi!
While on the subject of fuel injection, can anyone help me on locating a reliable source for buying a Bosch Warm Up Regulator ( BOSCH 0 438 140 108).
This is for a Euro 308GTSi QV from 1985.
I have heard about California Fuel Injection, can anyone supply a contact please? I live in Singapore. |

On most all computer cars there is a voltage sent to the O2 sensor from the ECM. During open loop a base signal is produced of approx .5 volts to substitute for the cool and unworking sensor. When the sensor achieves around 600 degrees it produces a working voltage and if the other sensor parameters are met, it will go closed loop and will rely on the voltage produced by the O2 sensor. If you get a varying voltage of 0 to 1.0 after the engine is warm then the system is probably working properly. Do not pay much attention to cold voltage readings. |

even my mechanic is stumped on this one. lambda sensor lead on my 328 is not recieving voltage signals from the sensor but instead is sending voltage in the opposite direction. i think it was about 2 volts and installing a brand new ecu dropped it down to .5 but there still shouldn't be anything going out to the O2. anybody heard of this before? |
