**Ok, to minimize the potential tangents, let`s just assume that 27 years in building and modding performance cars has given me a fair base of experience to work from here. LOL. **
(1) built motor/BT/E85/Methanol.
(2) setup will only differ from previous (non-forged) in the addition of a better exhaust manifold. Everything else will be exactly the same.
I`ll be self tuning with Versatune. The plan is to get a solid base map together, put in a few revisions from street pulls, then dial it in on a dyno.
Let`s start:
once the base map is established, can I use the data from my previous logs as a guide in developing the new tune? Ie; can I use the previous load/timing/boost/afr readings as targets in the new tune? (no, not considering going straight to final map readings. More like mid-tune numbers).
How big or small should my change increments be per revision? Can I make substantial jumps in the beginning or is it really mandatory to do small steps? (example: base map has a max timing advance of 4*. Can I bump that to 10* or would it be necessary to step it between 4 and 10? Again, assuming the requisite other parameters are also addressed).
I am familiar with boost tuning. VT is load based. I`m fine with that, but it begs this: with boost tuning you keep bumping boost to make more power (again, yes, of course keeping other parameters in check along the way) until adding more boost does not make more power, you can`t maintain afr, or you hit your goal. Would I now bump load the same way instead?
And likely the most important question I could ever ask: What makes a BAD tune? What are things to avoid that may be common to the platform?
