Vantuner no longer tunes them, as they are not reliable & any tuning will add more risk to already over sensitive injection system.
One issue , on this Delphi injection system setup, is tolerance on fuel rail pressure deviation, anything over approx 60 bar from spec at full pelt (1600 bar) & you have limp mode. A standard van is kissing this limit anyway so even tuning which avoids any rail pressure increase directly will lower this margin..So they can run good apart from going into limp mode under full load intermittently.. What a load of bollocks.. The creators should be ashamed of themselves – In ancient Greece, the word Delphi may mean “Womb”.. Clearly Fords 1st common rail offspring has a birth defect.
If you need speed limiter removal , thats no problem. For EGR delete ( assuming your EGR valve is currently working ok) just disconnect the vacuum pipe that operates the EGR. You wont get an engine light from doing this, same with fitting an EGR blanking plate. You’ll get a P0404 engine trouble code thats all, as this is a Euro 3 engine & EGR performance was not as crucial , unlike with later Euro emissions regulations, where any EGR issue will light the MIL ( Malfunction Indicator Lamp on dash) .
110ps MK7 Transit
Stock 110ps Transit Mk7 Euro 4 2200 have a tendency to develop a vibration at about 1690rpm on light acceleration & pushing the gas pedal & it goes. It can affect any Euro 4 diesel Transit but its rare on others . Some have fixed it by fitting a new genuine crankshaft pulley or engine mounts, or clutch but there is no foolproof repair route . Any repair or tuning that adds torque to that RPM point or corrects a loss in the case of a repair, can induce the vibration & its tricky to solve. Its a balance / calibration error, an argument between 2 maps if you like. Not something that can be solved reliably by someone like myself for various reasons. Here’s one – you adjust the calibration ( mapping ) load it in, & its gone, 300 miles later its back. Why ? Because some short term fuelling trims via an adaptation process are reset every time you reprogram the engine ECU so full torque, via a slight fuelling reduction isn’t available until the adaptation process completes. As you can imagine that complicates any fix. For this reason, vantuner no longer tunes or works on 110ps van’s. I do have some 130ps ish tuned software for 85/110’s, that has cured a few back in the day, but it’s tricky to install & honestly i’d rather not get involved anymore with them.
130ps & 140ps MK7 Euro 4 Front Wheel Drive Transits
I consider the 130/140FWD fragile & unreliable. The piston crown weakness that blights the 2.2 is most prominent on the 130 , & the usual Euro 4 issues ( injector wear, hunting, egr, turbo actuator failure) seems to affect the 130 /140FWD more so vantuner no longer tunes them, but will carry out other repairs like recalibration, EGR delete, software updates etc.
