Does anyone know what the default values for the following parameters should be for map 1 (V28 firmware)? I got mine used so I believe these values might’ve been entered in by the previous owner.

I can't remember what the default biases are but definitely lower the boost failsafe to 22 until you start adapting the tune to your car and get logs to make sure everything looks healthy

those look like settings for something like a 400 cell DP (AA for example).

Standard FF and duty bias is all 50 for stock DP

shift redux is 60 standard

Thank you again colonel. Here are pulls after these changes. Could you tell me which curves are still needing attention. Im trying to compare all of logs and learn something XD

Duty 4500 and lower need to be dropped in increments of 5 until ecu_psi is about 1 psi under dme_bt and throttle is mostly at 100 for the entire pull

Manual Transmission Map 1 log. ~3 Gallons E85 and the rest 91 Octane, stock downpipe. Looks like I probably have a little headroom to work with, but want to make sure it looks clean before stepping up to another mapping.

Thank you!
Looks good, try this Map 6 at FF 35

Hey colonel, me again lol..im probably missing something.

Here is my latest. I have lowered some duty to 15 and wondering if that is to low now. I cant seem to get them close. My throttle isnt 100 for the full pull.

https://datazap.me/u/vunit/log-1746749671?log=0&data=1-2-15
No its not too low. I'd probably set FF to something like 30-35 then work on duty afterwards to get that ecu_psi 1 psi under dme_bt the entire pull
