Audi A4 B7 1.9 BRB with EDC16U31
I’ve worked on this one before when it still was running original engine and hybrid BV turbo.
Due to how big new setup was, customer went with someone local(makes all the sense to me) but they got 0 results and did a reckless tune that would quickly destroy the new investment, MAP sensor was incorrectly written into the file, diagnostic limits were done badly so VCDS would show 5252mbar on logs when obviously that wouldn’t happen, limp mode turned off to avoid the intake temp sensor issue, injector data not changed for new ones at all, cowboys and % lovers.
Customer came back and asked if I would take this on. I agreed as I knew Jay takes good live data logs and has good approach to the whole process.
New setup is as follows:
Pd130 AWX swapped instead of BRB
120% firad injectors
GTB2265vk turbo
4paddle clutch kit
Pd150 head bolts
4bar MAP sensor
Creations motorsport 51mm inlet (no EGR or ASV)
2.5” intercooler with matching pipework 3”downpipe to 2.5”straight through
Enclosed air intake to front grill
As usual, I’ve started with base tune, and with each live data log I was adjusting the file. And once the intake temp sensor issue was solved, we started getting some results. Days after our tuning sessions were finished, customer went to a local dyno.
319hp and 517Nm is a respectable result here.
Knowing current result, once customer goes back to a normal intake manifold (which will flow better than what’s there now) I expect to get 20-30Nm more in a good rpm range.
Great looking car and considering customer building all of it in his driveway… goes to show „amateurs” can get things done better than bad workshops.
