It will save you from the worst migrane you've ever had.
My car has been just that, a constant head ache for the past month and a half. I tune my own car, and for a while I was using the free stuff for Hondas, aka Crome. I was having issues with it on the dyno the first time I was there, on top of that I was blowing couplers and had a leaking BOV. The next time I went nothing connected and all I did was waste everyone at RTtuning's time. Vince hooked me up with Hondata S300 for a good price and I've just gotten it finally on the car.
It's a really simple software to use, I was surprised. Car runs a lot better on it too. Yesterday I spent about 3 hours street tuning it, just driving around. Was pretty happy with it, didn't get a chance to street tune boost quite yet but planned on doing that in the morning. This was my low cam map, solid AFRs through most of partial throttle with a slight problem with it going rich at high RPM very low load. Let me make this very clear to everyone reading. I went for a ride at about 10pm later that night, came home, shut off the car and did not touch anything at all until the morning.
So I wake up this morning, go out to the car and fire her up. Or at least try to. It wouldn't start. Nothing, at all. 2 hours I tried everything I could possibly think of to get the car to start, with absolutely no success. Started over againd with a completely different basemap, much much much richer than my current map. Car started right up. Another 2 hours of street tuning later, my AFRs are back to where they should be (and no weird rich part either). ...look at this map.
200%+ increase in fuel, overnight?! WTF?!
