I’m running map 2 and it’s a decent power increase but not earth shattering. Starting to wonder if some default settings are holding it back as I bought it used. Can anyone share the user adjustment settings for their stock (no mod hardware yet) GTI?
Fuel open loop is 0 and I thought I read it should ship set to 40? Also N20 TMAP = 1? Is that correct?
Going to set the boost safety on 25 as that is also 0..
I have it set on map 2 but it’s still boosting similar to stock at least via the VW built in (likely totally off) gauge
That’s correct 40 is default for fuel open loop but the usual recommendation for a GTI is 50 if you’re running pump gas or 60 if you’re running an ethanol blend.
Rule of thumb on boost safety is to set it 2 psi higher than the max you expect to hit.
On my car N20 TMAP is set to 1. I’m not even sure if this setting does anything on VWs because the actual label is referring to something BMW specific I believe.
Yeah the VW boost gauge in the performance monitor reports the stock boost request (not actual).
More settings to check while you’re adjusting settings is the fuel_30 through fuel_70 should be set to 100.
