Re: for tuners.. i was wondering..
Well Ive been driving on my first tune for about two weeks now and the car drives really smooth and pulls I think better than stock . My motor is an f22a1 I used an f22b1 map I found on xenocrons bin depsitory, I only changed the injector size to 510cc and adjusted the fuel maps to get a real consistant A/f.
The timing wasn't hard at all. I noticed while I was doing a pull that the powerband had a few dead spots and once it got past them it pulled hard again. I was going to adjust timing up and down in those area's to see if I could tune it smoother, But I'm using crome so I looked at the time map in 2d view and saw that it was really jagged. So to start off I decided I would try smoothing the map and see what happened.
It worked great the power was smooth all the way though the pull after that, so Ive left it as it is.
Crome and freelog work great together it makes tuning pretty easy. But tuning stock and NA is easy compared to tuning boost.
in another two weeks I'll be tackling tuning for my turbo. So we'll see how that goes. But honestly I'm not worried one bit. So far Ive loved tuning. It's so much fun and the first few weeks I was struggling with uberdata and I still liked it and believe me crome and freelog are way better than uber.
Give yourself some time to get everything sorted with using the software and hooking up the wideband and getting your voltage slopes set and things like that.
Your more intelligent then I am so you'll get through all that no sweat.

Re: for tuners.. i was wondering..
Still driving my first car that I tuned, second engine.
The first engine I tuned (d15b7) ran great, I didn't have any problems tuning it with Uberdata and it ran very well. I never really blew it up but it developed a rod knock that I wasn't really comfortable driving around with, which I don't believe had to do with the tune. I swapped in a Z6/Y5 hybrid and am running the same turbo setup with a very similar tune for a year and a half now and it still runs great. For some odd reason I had to gap the plugs much smaller than the b7 (which were at .030") which confused me for quite a while until I figured it out (now a .025" gap), must be the Y5 head? ---- I don't know, it runs great now.

Re: for tuners.. i was wondering..
first car i tuned is my accord this year in july. its NA, but tuning is tuning. I got the grasp for it now and im fairly confident.
i've tuned some high compression engines(11.5+) as well as some boosted engines since then. I've also e-tuned, lol.

Re: for tuners.. i was wondering..
First setup I tuned was for myself. Not really much of a tuning job, but it was about 4 years ago at least. A complete hackjob setup really, mostly cause I was broke as hell. It was a 91 crx dx, z6 swap, homemade obd1 conversion harness (taken from a 91 accord and an old dual-point ecu), dsm 450's controlled by a vafc, and a 14b with the carb spring wastegate setup. :P I had nothing really to tune it by, with the exception of how it sounded through the rpm's, and by checking the plugs after a hard pull. Amazingly, the motor lasted 6 months of solid abuse...never once gave me any beef. I ended up wrecking the crx, and sold the motor. Second time I tried tuning an afc that way didn't turn out too good, as evidenced by broken pistons and a broken rod. :P
