Goal: I want to clone the original Honda ignition matrix in an Ignitech CDI.

A little story:

I have a VTR 1000 F (2001 with fuel gauge) and Ive read probbably all of 1000.org, Superhawk and other forums about ignition timing and the +4 ignition advancer, pros and cons, what it does and the theories about the later models of the VTR ignition rotor. Over the years alot of ppl changed to a +4 ignition rotor and witnessed "an alarming engine noise" which is a direct consequence of the advance: more advance means more pressure = louder bang. Installing a + 4 rotor advances the hole ignition matrix by +4 which has its uses but also disdvantages and dangers. As the +4 rotor is not available anyhow for a long time I have been lookingfor another solution which lead me to a programmable Ignition matrix from ignitech (TCIP4 or DCC-DIP2).

Hint for VTR-Owners with HISS Models: Ignitech now provides Plug and play DIP2 (=TCI+Converter) with all connectors. The old TCI box and Converterbox is replacec by one Ignitionbox, Might be good for ppl who have lost or broken their keys or just want a programmable box (quickshifter etc...)

Ignitech provided a standard V2 mapping for my VTR with ignition values dependent of the TPS-position and rpm (please see picture below) which is very conservative and therefore less powerful (and less noisy!) compared to the original mapping from my VTR 1000 F (Facelift 1). The Base advance in the Ignitech matrix is 5° but the VTR has a standard base advance of 15° so just change it to 15 and add +10 to all values in the matrix to get values matching BTDC. If I remember correctly I ve read that this map seems to be the old 97er VTR map with less advance which supports the thesis that only the old VTRs benefit from a mechanical +4 advancer as the Facelift 1 + 2 (both with fuel gauge) already have some more advanced ignition values stored in the CDI.


Baseadvance = 5, to be correct it must be changed 15 and all values +10 up to match BTDC - Values


So far so good.

With that in mind its probbably not such a good idea to plug the static +4 advance rotor in a 2001-or-later-model. Instead I want to tuneup the values differently between +2 and +4 degrees in the matrix according to my to my personal needs - but from a ignition map of a VTR Facelift Model. To do that I need the original ignition values of the HONDA TCI second generation. It should be possible to read it out with the proper tools/software.

In my opinion that would benefit a great deal to all Firestorm/Superhawk owners.

Can anyone do that/help with useful information/contacts/...?
