123 iGnition Mapping Library?


Recommended Posts

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.

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.

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.

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    The BMW 2002 Production Run

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
