123 iGnition Mapping Library?

[Captain Manly]

What about starting a collective library of ignition mapping of those who are using the 123iGnition?

 

We can disclose what the engine set up that you have and the corresponding mapping codes that we could try, given each individual's engine parameters.

 

For example, I have dual webbers 45, with Schrick 292 cam, port/polished head, MSD 6A, Bosch red coil and I am using the same numbers as what is stated for the Ti version.  

 

Thoughts?

I like it  

 

There's several great threads with great info out there, but it's often a lot of digging and reading to get to what you're hoping to find, and not necessarily under the thread-title you would assume to search for.

Which Ti distributor?, there are 3, with widely different maps.  Specifically the strange footnotes (#12) for "026" distributors.  Also, a lot of the footnotes seem to reference gas quality for differences in the RPM selection for 25 degrees BTDC settings.

That's why I think we should set up a data collective, given our individual engine set ups with respect to RPM ranges.

Here's what I'm currently running on a stock Tii that is running pretty sweet.

The gray curve is most current as of April 7, 2020.  I find that I don't need to mess around with it much, but I have tried a number of curves over time as seen on the 2nd tab of the workbook.

Well this is what I have, please feel free to chime in on ideas:

 

9.5 Piano tops

Schrick 292

Dual Webber 45 jetted at 800 feet, intakes ported and polished

MSD 6A with rev counter

Bosch Red Coil 

Lightened fly wheel 

 

TIA

Also curious if anyone when checking against timing light finds the 123 off a bit.  If I set the green light at TBC for #1 per instructions, then set up curve in program and finally check against that with a timing light, I often find that it is a few degrees out.  Almost like the green light method at TDC is not completely accurate.  Anyone else have similar findings.  Running a curve almost identical to Swiss 2002tii, but I find that If I check with timing like I need to turn the 123 a bit from the basline greenlight settings.

Green light will only get you in the ballpark to get the car started/running. 

 

ALWAYS confirm your timing at a few known RPM's with a timing light.

Hi, I've recently bought one of these. Does anyone have a good map for a completely standard 1973 1602?
