Everything would be so easy if Honda would have printed that bloody map to the workshop manual like Yamaha did with the RZ 350 ...
As I don't have experience with 4 stroke maps I can't argue with the map values. That's the reason why I was asking if anyone would have a map.
(I'm using the Ignitech mainly as a quickshifter ECU - optimization of the map is secondary for me)
But I do have experience with programmable Ignitions/EFI on twostrokes since 2005.
In any System you need to tell the unit "where is the crank" by using a characteristic position like a missing tooth.
The procedure to test it is always the same. Measure TDC position (or any other), mark the rotor, program a curve that fires at the mark. Use a strobe to check and correct base advance until mark is matching.
The base advance value of 5 deg for the VTR is simply plain wrong on my individual bike.
The consequence is simply that the values in the Ignitech map are not deg before top dead center.
If you need that, you'll have to increase the map by 11 deg and set the base advance to 16 deg.
Is that map right? I can't tell. But I can ask experienced people for their opinions.
On the German Megasquirt forum people advised not to exceed the 42 deg.
They said on the dyno 3 deg less would hardly loose power, but 3 more would result in knocking combustion.
Older Ducatis would only use max. 32 deg.
Newer Ducatis for example have pretty high low TPS/high rpm values of 60-70 deg.

Adjusting the base advance and then using the unaltered map would certainly be safe. Though these values seem a bit low to me.
And more importantly they don't match other information you can get (i.e. 15 deg at idle and 42 at 9500)
For myself I decided to start with some lower values and do some dyno testing and/or attaching something like this:

Also note that I don't want to run down anyone's work nor say that the Ignitech is crap. In contrary: I have bought there several times and it's a great product.
