Hey!
I am not an expert on modding but I bought a modified VW Golf mk4 1.9 TDI ARL with a tune from the shop.
The car made a tremendous amount of smoke so I started to get into it and doing some changes based on the original map.
First let me introduce the mechanical car mods:
BMW Turbo GT2256 hybrid to GT2260
Improved CAM 272º
"Valve lifters" INA Black
Downpipe 66''mm with original muffler
Injector upgraded to Firad120%
Bigger intercooler (all hoses replaced)
Original air intake (but box is fully open from the bottom)
Stronger Clutch (Sachs racing, if I am not mistaken)
So far I managed to decrease the smoke which is nice but I feel like some things might not be so well tuned....
Here are some findings:
The turbo only starts to kick in after 2000rpms (I believe that's normal for such a big turbo, but maybe there are ways to improve it)
While driving at roughly 2500 rpms if I press the accelerator pedal (to overtake) the car goes instanly into Limp mode (Safe mode), I've been trying to change the N75 map but didn't seem to find the correct values...
I have a Boost Gauge pressure inside the car (connected to the tube where the EGR was) and at 3300ich RPM (at full throttle) it goes into 3.0 Bar, however based on my calculations this should not happen right?
I am including in the post my map and the log file from the last run (group 11)
PS: I used EDC Suite software, and changed all the maps under "code block 2"
Appreciate a lot if you can check my map and provide some inputs/upgrades
