Mivec cam tuning
Hey guys, so like the title says, i just recently heard that you can tune the cams in and evo IX threw the mivec map. Meaning the lope, etc. Someone told me i think on here that you can adjust the lope of the cams threw mivec, meaning to make it more lopey or less lopey. I tried searching and only came up with ppl asking your same ole qeustions about what cams to get or w.e.
so has anyone seen this first hand or done it?
any vendors or tuners on here, have you seen it or done it?
im just trying to figure this out.
thanks

The addresses are:
293A is minimum advance (-1.2* is the max value)
293C is maximum advance (28.8* is the max value)
the scaling is:
<scaling name="ValveTiming16" units="degrees" toexpr="72-x*0.6/32" frexpr="(72-x)*32/0.6" format="%.1f" min="-1.8" max="28.8" inc="0.1" storagetype="uint16" endian="little"/>

so you can actullyy make the stock evo ix cams sound lopey? idk if im following, i talked to my tuner and he said the higher the number away from zero at idle will give you the lopey idle....0 being the smoothest idle. does that sound right?

I have come to the conclusion that cranking the MIVEC to achieve a rough idle falls under some categories though:
1. Annoying
2. Ricey
3. Less stable
Why cause a headache for idle and stall situations when on the IX we can tune them away. My S2s idle almost exactly like stock, yet when I really need them to make power they will. This has many advantages from making the car drivable, maintaining a stock appearance to officers, and sleeper advantage to the Honda revving next to you at a light.
....Not that any of us would rev back
