VW MK5 KFMIRL and KMFIOP tables when using an external boost controller

Hi, I haven't even looked at my original file in winOLS and it's probably extremely different that an MK5, but what's the theory or idea behind those tables if I have an upgraded turbo and now using an external wastegate with an electronic boost controller?

Setup context: EA888 Gen 4 / VAG MK8 - Simos 19.6

- Built engine (Pistons, rods, valves, springs, studs, everything except camshaft and crankshaft)

- Brisk cold spark plugs and APR coils

- DQ500 Clutch

- Garret G30-900

- Hypergate45 external wastegate

- Sihrc labs cortex boost controller

- Snow performance meth injection

- 3.5" Downpipe

- 3.5" Intake

- 2.5" Charge pipes

- CTS Intercooler

- 91 octane

- OEM injectors and pumps

Bosch's KFMIOP & KFMIRL are the equivalents to "Reference indicated engine torque (ip_tqi_ref_n_m_air_vvl_cam_l) & Setpoint mass air flow for torque intervention (ip_maf_stk_sp_vvl_cam_l) in the SIMOS19 (and other Conti ECUs). It's important to note that there are 2 different sets of maps for these, cam_l and cam_h. "cam low" is used during WOT (during times when the intake port flaps are closed, or "low"), and cam_h is used when cruising or other conditions when the port flaps are high, and thus are not referenced when in "full load" mode.

For tuning with an electronic boost controller, a few considerations have to be made. You will need to tune the maximum allowed torque maps to request an airflow that will be higher than the maximum boost you will be running (use a 0.078 multiplication factor in WinOLS to see a rough boost target from the airflow maps). You will then be using your boost controller as a limiter to produce less boost than the ECU can request. I would recommend targeting 3 bar maximum request unless you are running 4 bar sensors.

You will also need to disable cap_l and cap_h monitors so that you don't get underboost faults when you produce less boost than the ECU is requesting. Make sure your PUT max setpoints and maximum intake manifold pressure limits are set high enough as well. If you have a good understanding of how the SIMOS ECU functions you will be just fine. This is a bit of a crude way to get it running, but once you are able to do a few runs and log mass airflow and torque at clutch you can go back and clean up your airflow and torque requests to match what the turbo is producing.

Good luck, and if you have any questions please ask.

Thanks that's some great info to get me started, I do not have a good understanding of the Simos ECU but I'm starting to learn, does your shop offer any lessons or tuned files?

I'm working with DBV2 from Canada, he's the main supplier for the upgrades that we are already running

Edit: I do have 4 bar sensors, just not installed atm need to learn how to scale them
