TPS Sesor Reading
I've been trying to work on my tune for a couple of weeks now and just noticed that my tps readings are never below 2, shouldn't it be around 0 when I'm idling?
I've attached my latest log in this post:

I would not be too concerned. I believe the ECU does compensate for that. Your logs show 2 but the ECU after seeing 2 on idle reads that as zero. I have moved my TPS (TSS) countless times, IAC changes, yet in log it is always zero for TPS.

It should be showing a % of throttle on a scan tool. TPS should not be adjustable. Minimum Air Rate should be checked and set if needed. That woud be the idle TPS setting.

Re: TPS Sesor Reading
In the setup section of my aftermarket BS3 directions it says that the TPS should be between .5 and 1%. I don't know anything about tuning, yet, but I did see that in the instructions and though I'd offer what I could.
Sorry if I don't know what I'm talking about.
