Not today, but over the holidays when I was bored and weather was ok, I blanked the EGR, adjusted the Cam angle and created my first Stage 1 map, did some runs and logs - everything appears to be fine. I did have to fine tune it, currently on version 6 of the original.
Took me around a month, or just over to learn the basics, I had 2 mates look over the map and I did get a few tips how to improve things. But overall, it seems to be working fine... bit more wheelspin and overtaking on A/B roads now isn't as scary.
Edit: Encountered another issue though, Idk why but my windscreen jets insert keep poping out, its a little bit of plastic, I think its time to do a bodge job, CBA to keep on replacing them. Still, I like a good ol' S... Box.
