Re: Boxer 3.0 2011 no Speedo

I don't have a diagram in front of me. However I am quite sure that the ABS recieves the Wheel Speeds and puts them on either the CAN or VAN networks. Things like the Radio, Instruments, Airbag, BSI, Park Brake etc. will then get them from the network. I dont think you can look for a raw "Speed" sig...

Re: Checking inlet metering/ SCV/ volume control valves

Burt Ok so how fast should I expect to see a change in fuel pressure once a higher duty/ demand from acc pedal is applied? Using the ACC is a good way to do the test but not the Best !! You can create a larger demand on the HP System using an emulator or as Scott has outlined. Full pressure build up...

Re: Checking inlet metering/ SCV/ volume control valves

Ok will do but what should a known good show against say a sticky or slow to react solenoid? I.e high duty, current flow? Look at what it is commanded to do and what it is doing. Scope the Power supply, Duty Cycle, Current Draw and FRP Sensor. I like to drive them with a PWM Emulator, you will need...

Re: add blue touth

where the laptop can be connected to the scope via usb and then have a tablet that mirrors the laptop via the remote ripple and you can control the laptop from the tablet
Wireless or bluetooth keyboard will do that.

Re: 207 misfire under load

What could cause a positive inlet pressure instead of a vacuum ? Vacuum is created by the throttle plate in the closed ish position, once the plate is lifted then it will move towards atmospheric. I would measure manifold pressure with an analogue gauge to verify MAP integrity. How is the PCV on th...

Re: Exhaust vibration??

Initially I thought a battery powered grinder had been used to cut the CATs off but now I'm not so sure, the cuts are very clean and no jagged edges at all are present, which makes me think the thieves are using something else to cut them off. These bad boys will put a clean cut in a pipe faster an...

Re: Mechanical Injectors Tests

I digress. That piezo clamp has uses away from the the old mechanical diesels. I have found some used for it on common rail and Hydraulic brake pipes on ABS. Can be used to catch a stuck / not activating valve in the abs pump. Is it the amplifier that had popped or as #picoben said in another post y...

Re: Mechanical Injectors Tests

this is a Transit Di. The injectors are not electronic controlled, they are pure mechanical hydraulic pressure operation only . Understood !!! In this case then I'm guessing it does not have CKP either ? However, if you do have a bee in your bonnet then perhaps get an abs wheel and inductive sensor...
