Just saw this TOD last night and copied its values over to the newer 20539 tune.
While doing that I noticed that the L1-L3 values differ for the initial throttle position values. Why are these values different across each of these tables (yes, my knowledge base on these matters is limited)? Is this related to firing order or the amount of vacuum? I also do realize (at least from my understanding), that this tune switches to the F tables pretty early on, which would at least explain why only the initial values on the L tables were changed.
I did install the tune this morning. The first thing I noticed was that the TPS indicator on TuneECU didn't turn green; this is the first time I've had this happen, but it doesn't seem this is a bid deal as this is self-adapting. I also noticed it didn't idle as smoothly as the 20539 and was a little jerky off the start, but while riding it definitely felt nice.
