2. Only "smoother" acceleration while cold driving below 35°C - then when engine is hot, only enrichment at acceleration beyond 35° throttle position
Only problem with the Original ECU is that its very sluggish and non precise, well its a result from the very early beginning years of lambda/ecu concepts – as you already know.

Remember before Lambda, the 911 Porsche ran great!

Well, with with a "proper working" Lambda it works more efficient. Fuel saving where possible and enrichment for performance where needed. No overfueling due better mixture and by this more efficient combustion, less residues and obtaining longer lasting proper oil condition.
