Two things I've seen crop up a lot is people trying to use a "bin" file or a tcd from RT, and also not knowing about the need to cut the consult wires to get data stream. The information is out there, but it's not obvious to the 1st time tuner when they receive a Nemu in a box and install themselves given there is no documentation in the box.
I'm going to do a bit more work on the thread I posted above, get some screen shots and try post up some basic setup stuff to get a tcd working for the 1st timer.
Unfortunately there are no base "tunes" yet for specific setups, so if you don't have a wideband and/or some experience with tuning, plugging it in and starting the car is not going to be a instantly rewarding experience.
If I can find a car with a stock Ve and some time I will make a Ve startup file that can be driven on to get a car running ok, atm I have only tuned a 16ve with n1 cams and 16ve maf on a nemu so it's not going to be a good file for anyone.
