Aftermarket Cruise Control Switches – Ford Transit MK7

I saw a van today for cruise activation that had the aftermarket switches fitted, which is possible by cutting out a section of the steering wheel rubberised lower section. The cruise didn’t work after activation. Customer said he had to cut away part of the plug & was then faced with 2 choices on how to plug in the connector. Had no time to check the work beyond measuring the resistance of the switch circuit. It measured 2.1Megohms, thats about 2 million Ohms more than what it should be. Pressing the various cruise buttons had no effect. I’ll update the blog if the customer get’s to the bottom of it, but for now , the previous advice still applies – get yourself a Transit wheel with buttons from a high spec transit , or choose one from a CMAX MK1 ( 2003-2007). Try Breakerlink.com if ebay yields no result on your search. & stop looking for Focus MK2 wheels, as most are incompatible, which is annoying as they look 10 times better.

Low Boost on Transit Custom 2017 ? Its an early 2.0l

No fault codes , just low power overall. Its the turbo actuator apparently according to a very helpful customer, who gave me the report from Ford after i had a look & after little head scratching declared it to be a warranty job. . .I’ll measure boost while driving if another comes in with the same symptoms. Every day’s a school day as they say ūüėČ

2014 Connect “MK2” 75ps 1600 TDCI Tuning result.

Well here is a 1st , a 75ps Connect MK2. I have only done 95 & 115ps versions up till now but am pleased to say the 75 makes the same power as the 95, I.E 120ps. Hugely improved. 115ps models will make about 133ps, & the differences in engine hardware are the reason. I have lost my notes but Turbo & DPF are the culprits from what i recall from studying Fords’s excellent Microcat parts system when the Mk2 came out..

Christmas 2018

Well it’s Christmas again & vantuner still isn’t giving a discount, but it is easier to book as less owners are getting work done this month.¬† As for general news, new vehicles covered etc, there is almost none but i have worked out an easy ( cheaper) way for speed limiter removal for¬† late model Corsa D speed limiters, of about 2011 vintage, just before that real ugly bastard fiat doblo clone version¬† was released.¬†¬†

Need more power ? more sarcasm ? call or whats-app me on  07956 555 666. Office hours, monday to saturday. 

Updated UK MOT regulations as of May 2018

Aimed primarily at those who disable emissions control equipment like DPF system’s the new MOT reg’s ¬†include a more thorough physical check of the DPF system, so no¬† just cutting a hole /hatch in the DPF filter body to remove its filter media,¬† you’ll need to open & weld it back along a¬† seam. There’s still no check on its or the¬† EGR systems efficiency much beyond a basic smoke check.¬†Other MOT regs update include a lit or malfunctioning MIL lamp being a fail, & physically checking EGR is connected¬† & present.

Making these systems reliable is the only way to thwart the desire to delete these systems though as hugely expensive & problematic repair options continue to override the public health concerns of owners with afflicted vehicles.¬† We could all go electric i suppose, but¬† then i’d have nothing much left to tune. I couldn’t even find DRIVE on my mates Tesla last week, so bollox to actually remapping it.

2012 Transit 140 Sport – MPG & Top Speed – update after 60k.

On  recent 1500 mile run to Germany.

125mph on GPS

& 34 mpg on the on-board computer averaging 85mph

60k miles done so far on the current tune.

The Michelin Pilot Sport 4’s are doing 18k on the front also which is pretty impressive, although it is a ¬£200 tyre !

Power wise, its the usual maxed out tune that these Euro 5 engine’s seem to ¬†lap up ¬†– so circa 180ps /420nm.

Its Curtains for 125ps & 135ps TDCI MK6 Transit Tuning. ( & a few others )

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. 

LDV Convoy still a good van to tune

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

Ford Transit Diff Ratio’s & Axle Swaps

“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 )

Corsa D & Combo 1.3 Speed Limiter Removal

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.
