Good on ya Gav,
Yep got the serial interface so my lappy can strike up a dialogue with da ECU, hows that for nerdy talk, also got the valve lash set at 0.15in/0.20ex . So what I might do is set me TPS back up to 54 then use the slider in the idle cell to richen it up to slow da revs down. Then maybe reduce the map 10% between 3k to 5k so to improve the mileage but not starve it in the high revs and leave it alone between 2k and 3k so as not to reintroduce the hick-ups again.
Raz suggested his map because I have the air box with a K&N filter with 3 X 1" hole to-wards the rear of the lid and a set of Staintune pipes and cans, like his. I think his geological position compared to mine might be the reason that mine runs lean up in the high rpm's.
Just one other thing did you notice a 300 rpm reduction on the taco compared to the stock ECU, mine with the stock ECU is sitting on 4k @ 120 kph but with MyECU it's doin 120 kph @ 3700 rpm, this also the same at idle.
