Hi everyone,
I just thought I’d add to this thread by sharing my experience in enquiring about the tuning of the transporter with the Bosch ecu. Earlier in the year.
I contacted MRC to try and understand costs and process of tuning my van. I’ve a 2022 6.1 150bhp with 7 speed DSG. The stock map is horrendous so I’d love to get it done. Issue is I live in Ireland. MRC are in the uk. When I contacted them in January, I had this idea as I was coming over for 2 weeks (renovate my sisters bathroom in The Wirral) that they might be able to do it for me while I was over. Now I naively thought this was a 1-2 day job and may cost 500-600 quid. Well I’ll just post the email correspondence that I began on MRC’s web contact form thingy…

Hi, I live in Ireland and I’m driving to uk in February for 2 weeks. I’m looking to get my 2022 DSG transporter mapped. I presume it has the Bosch ecu and I want the gear box mapped too. Is that possible with you? Thanks

Hi Adam
Yes this is possible, 2 weeks is a bit tight as sometimes we have issues with the ECU's being stuck in customs. As long as we don't have any issues then 2 weeks should be enough time.
I have sent through an estimate please check your spam folder also.
Please can I have your chassis number also.

Hi Sarah, Thanks for the reply.
I wasn’t sure of the process. I thought the whole thing could be done in a full day (mapped, rolling road, etc.)
So am I right in thinking, the ECU needs to be removed from the vehicle, sent away to be ‘modified’ then sent back, refitted and then what? And while the ecu is sent away the vehicle is immobile at your place?
The quote you sent is for a different vehicle. And doesn’t state whether the DSG will be mapped also.
Mine is a 2022 transporter DSG 150bhp.

Hi Adam
Unfortunately not as we have to get the ECU unlocked and then we can tune/ code to the code etc
Thank you for the extra info, as your registration doesn’t work on our system I had to put in a random model of car to be able to create the estimate. All of the details I have put on there are correct for your vehicle. We should be able to tune the DSG for you also
So, that’s what I got. The ESTIMATE that Sarah sent is £1500 ex vat. Wasn’t clear if that included mapping the DSG either but I’d hope it does.
The cost is one thing but having my van sitting in a garage in the uk for possibly more than 3 weeks is the biggest hurdle for me. I even then thought…could I just buy a second hand ecu of the same so they can send that off, get it cracked and sent back, then going in with my van to have ecu swapped out for the existing one, tune/map the engine & gearbox, then possibly selling the one that’s removed? I dunno.
Anyone got any thoughts on all that?
