What I've done in the past if I only needed 2 different shift points was to use 2 shift lights, that's for an automatic where you're just shifting into 2nd and 3rd. Probably not a practical solution if you're running a 4 speed or more. The MSD "Grid" system ignition allows you to program individual shift points for each gear. I think the MSD Programmable Digital 7 Plus also allows individual shift points, you'd want to verify that. I also think most of the older Programmable Digital 7 Plus boxes allowed individual shift points too. When MSD introduced the "Grid" ignition they discontinued most of the other Programmable Digital 7 Plus boxes they made, but I've noticed there are quite a few of those for sale used on the internet if you look around. Many drag racers are replacing the Digital 7 boxes with the Grid. If you do look at something like that you will want to check the NHRA rules, not all the Programmable Digital 7 Plus boxes are NHRA legal in many classes, including some bracket classes. Whether that's a concern of course depends on where you race and the type of racing. Many of the MSD instruction sheets are available on line, so you can check if a particular box will do what you want. I'm not familiar with the shift light you mentioned, but it may not be as confusing as you suspect. If you set it so that the shifts will light up in order, it really doesn't matter which color comes up, you just shift each time it lights. I think some of the EFI controllers also will support individual shift points.
