Hello everyone. My name is Juan, im new at hp platform. I have a 2011 a4 quattro s tronic (eurospec DL501) with built engine and gtx3071r gen2 custom turbo kit. My tuner couldn't tune my car with eurodyne (thats was my plan A) bc of my euro spec set up, so i bought the HP platform.
So, while im trying to get a refound for my tuner to pay an HP tune (things that happens when you live in a LATAM country with dollars restrictions), i started messing around with the car on wg cracking pressure boost (around 14psi, boost controlled by GFB force III EBC) and OEM fueling (my set up is intended to use Mabotech DI injectors, autotech HPFP and walbro 450 LPFP).
My whole experience is with stand alone tuning so this is like starting over for me lol. I?ve been reading a lot of torque based tuning for MED17 but every forum a read is in VAG lenguage. So im learning torque base tuning AND how to traslate VAG to HP at the same time.
I downloaded some tunes from this forum to check them out just to have a hint about what to do and they were extremely helpful, thank you for sharing! the car improved pretty much from the stock tune but now i think im hitting a limitation i cant find, so maybe someone can help me move on a little bit more and learn a little bit more aboute tuning this ECU.
I attached the first log i made when things started to go a little crazy, it seems like the car is limiting torque to 350/360NM clutch or load to 200, dont know which one (my guess is load to 200), bc when i hit 200 in load the timing goes back (no timing pull, i think some table is limiting the output) and load starts to oscilate. This situation started showing when i tried to increase boost a little bit from 14psi.
FYI, the Optimium torque table is escalated to 250 in the load axis, the max load is also at 250, and the torque to load table is matched with the optimum torque one, so dont know where to look for the limitation. The torque monitoring tables also are increased and matched with the tables i mentioned before. Any help will be appreciated
About the lambda strategy, i used what Tyler explained in a post about taking the control temperature down so the system will follow the temperature control lambda tables, and im staing pretty rich just to play safe for now, until i can push boost a little bit up
