Transit & Custom 2012 on Euro 5 Tuning

2012 on MK7 Transit Customs ( Euro 5 ) , right up to 2017,  all the share the same engine & ECU & now can all now be tuned tuned to  at least 175ps  / 435nm ( that’s at least 185ps when measured on a cheap dyno 😉 ) .100mph speed  limiter defeat also inc. trickier late software 125’s.These will do the clock once I’ve done my bit (125mph)

The dyno printout from a  100ps hire van  I  tuned 2 years ago, shows a good gain ( 450nm max ) & the tuning has improved further since..I upgraded it to 155ps prior to tuning it to see what a stock 155 makes…

If maxing out your new van isn’t your cup of tea I can alternatively take it to 155ps or on the regular Transit, to 140ps using factory software via a simple exchange ECU..

Warning  – The ECU position on Transit Customs is effectively a water trap so any disturbances must be made fully watertight again. Tuning requires ECU opening   & replacement security bolts etc. Its an involved process compared to most other vans & ecu’s   – It takes longer to do this part ( well ) than it does to actually tune them!

I have seen several bodge jobs with damaged ECU’s  & wrong security bolts etc ,  & 2 stories of subsequently leaking ECU’s costing thousands to replace etc  all done by recognised names in UK tuning so choose your Man carefully on this one!    Vantuner takes time & great care to make the job as invisible as possible..bring a book to read basically 😉

Martyn, just some initial thoughts on the map. I think You are underselling what a difference the tune makes .It’s like a totally different van. Miles quicker through the gears, huge improvement in pickup in all gears. On the motorway there’s tons of torque and pace and no more gear hopping……80mph then drop to 45-50mph and happily can leave it in 6th.Oh & still maintaining 30-31mpg whilst I’m ragging it its tits off!
Well well well impressed so far! Thanks very much! Super job

Hi Martin, just a quick email to thank you for the work on my van, after driving it for a couple of hours it feels like a different van altogether, very responsive and pulls well through the gears, very impressed. As I said I did a lot of research on this before choosing who was going to do the work. After meeting you and the now seeing the results I made the right choice
Thanks again , Phil

Hey Martyn, sorry for the late reply, I’ve been really busy. I’m really happy with the van now, 120 it tops out at, 3000rpm but it obviously isn’t geared for any more 🙂 Cheers, Mel.

This is my second van Martyn has done . My 1st was a 90 3 years ago and that was fab ! Now I have a 2012 mk7 sport van and Something had to be done , the van was ok but felt it was it was lacking something ! Now Martyn no longer travels to tune I did a postal remap and WOW !!!! The van is hot …. fuel economy is still 25 but the performance is way up there !!!! This was a 3 day turnaround postal remap and 1st class service again
Thanx Martyn if anyone has a sport don’t hesitate DO IT !
