What will my 120ps Connect new shape make ? 133ps & 335nm is the answer, measured on a good dyno , Hardware wise 100 & 75 versions are identical & the 120 uses a different turbo..
So many Euro 4 ( & 1.8 Euro 5’s ) Transit Connect owners seems to have EGR valves failing these days, with running issues & P0490, P1103, P1102 P0404 Sensor Circuit A dtc fault codes seen very often.
The 90ps, 110 & 75’s are all affected. The DTC fault codes beginning 11 are “companion” air mass faults as well, but these are often just indicative of a faulty EGR, as one of the MAF sensor’s jobs is to monitor EGR performance. Vantuner can switch of the function of a faulty or working EGR in person or by post, at about a third of the cost of a new valve, which is a pricey Ford only supplied item as it comes complete with the entire intake manifold!
Plenty of discussion about this very problem on the Ford Transit Forum ( fordtransit.org)
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.
Problem solving in cases like this van’s relies on a tuner having access to something called a description file, an “A2L ” a ” Damos ” , These illegally gained manufacturer’s files identify maps & functions & would in this case allow the rail pressure deviation tolerance data to be increased, but no such files exist ( outside of Fords Dearborn U.S.A HQ) for Fords of this vintage so no go sadly.
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 Transit Mk7 Euro 4 have a tendency to develop a vibration at about 1690rpm. It can affect any Euro 4 diesel Transit but its very rare on all models apart from the 110. 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 by someone like myself for various reasons. Here’s one – you adjust the calibration ( mapping ) load it & its gone, 300 miles later its back. Why ? Because some short term fuel trims via an adaptation process are reset ever 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.
130ps MK7 Euro 4 Transits, I consider the 130 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 more so vantuner no longer tunes them, but will carry out other repairs like recalibration, EGR delete, software updates etc.
Usually of about 2003 vintage, the Convoy are beast of a van, often long wheel base , twin wheel high roof etc. Great candidates for a camper conversion or for one man & his beard (& dog) road-home conversions etc.
Often 1st owned by like Royal Mail & charities.They come with the excellent Transit Duratorq 16 valve turbo diesel engine in either 75ps or 90ps limited to 62 or 70mph.. All Transit tuning & maintenance advice applies… the limiter is also easily removed..see this page : Transit Service Tips
“My van is screaming its nuts off on the motorway”, is a common complaint & leads many owners of rear wheel drive Transits get in touch hoping a remap will fix it but it is a common misconception that a remap can truly change this.. Whilst more torque & a quieter tuned engine can sometimes give the impression of less rpm, its just an illusion,
The true solution is a different axle ratio, achieved by an axle or diff change.. if you have a 5.11 or a 5.13 currently, an indicated 70mph will be made using about 3500rpm..Anything over 3000rpm can be noisy..I’d recommend 1 full “point” so something in the low 4’s like a 4.27 would suffice without acceleration suffering too much. How about a 3.73 i hear you say ? X amount of torque will be needed depending on your model & usage so get in touch to discuss tuning options..Vantuner doesn’t do axle / diff changes )
Anyone can enter their registration number or VIN here & bring up quite a detailed spec of their van..follow this link & select vehicle.. if the option to enter reg isn’t showing, go back to the home page , select preferences & select united kingdom. the reg number entry should now work.. if your reg wont work enter your VIN. This is a handy service for looking up what axle ratio was originally fitted , among other things.. to search for items once the spec is shown without trawling through every entry, press CTRL F , this in many browsers brings up a search widget for the current pages shown content.
BT Fleet , Openreach & various other UK utilities still seem to be auctioning off these from time to time & nearly all have a 68 or 70mph limiter, which drives new private owners nuts from what I can tell . No main dealer can remove them despite the girl on reception saying yes no problem I’ve checked with Gordon & that’ll be 100 quid please… Vantuners removal solution on these is a bit long winded & expensive, compared to many other small van solutions, but is effective nonetheless & an optional power or economy tune at little extra cost softens the blow. Model year 2008 on vans seem a little easier than earlier ones thankfully.
Sometimes the dyno surprises & this Vivaro is a good example. The van’s performance in mine & the customers opinion was transformed yet it “only” made 135ps & 311nm on a local super honest Dyno Dynamics dyno.. it ran great prior to tuning & was very well maintained so I suspect they don’t make the specified 115ps as standard.. sadly i couldn’t make the session to load the stock file for a “before “ run.. It’s an epic tune that I have worked out for these over the years nonetheless so no need to change anything…
A nice long term report came in today..

Hi Martin …long time no speak …
just thought i would let you know my van has now reached 150,000 miles
and still running perfectly ..let no one say re-mapping shortens the life of an engine ..it has never been in the garage for engine related problems since you re-mapped it at 5000 miles ..
Many thanks ..hope your keeping well ..feel free to put this on your website ..will have to change van shortly so will be in touch ..
Nice result on Ian Jones’s 2007 Mk7, it was a 110 originally but is now running 115 injectors & software, & is tuned as far as possible in the 6hrs we had.. Exhaust Gas Temperature stayed nicely within limits , smoke level is zero before 2700rpm & “acceptable” after that. The curves as you can see below are very smooth & boost still stock at 1bar, there’s room for more power & less smoke for sure, roll on the next session 🙂 as a result of this session, a 155ps (smoke free !) option is now available if you have a MK7 110 or 115 in perfect order.
