Target17:
You might want to stress a bit more in your posts this tool is about understanding what changes are doing, figuring out what is most likely better, and finding shift points. I personally thought this was going to be telling me the gear settings to try directly. Which I consider an error on my part, not yours, there were comments in your posts that implied this, but nothing really said it. The last line of the second post is as close as you come to outright saying this though(and that was added after I had already set an incorrect expectation in my head).
Managing expectations - ah the watch word for software marketing. You are probably correct.
The thing is, it can help you with what changes can be made. It is just that the process of it is a bit nebulous, if you know what I mean. Getting nebulous with someone who is flopping around over the straight up math is a fruitless activity. Look at what happened with that one guy and the Peak Torque thing - "Where is it" when he had just typed it... What I figured is that a lot of the finer points of using the tool would come after folks had it in place and were a bit more comfortable with it. I imagine the ones that are uncomfortable with a spread sheet are hesitant to change any values for fear they will break it.
Using the example: We have us a Stroker monster here. If you shift at 6400 RPM, you are in the redline and a heartbeat from the rev limiter, in fact you may find yourself short shifting it to keep from landing on the rev limiter like a ton of bricks and maybe burning your engine - definitly going to cost you in the drag race to the first corner. The torque at that point is 500 ftlbs higher than where you will land after you shift - in other words, you've got torque to spare in first gear. Also, look at the speed table - 53 mph when you shift, and 60 is just 800 rpm away.
So, let's see if we can take advantage of all that torque and get to 60 before shifting. Will this be an improvement? You will have to drive it to see. But since we have so much torque up here, it most likely will be. Remember the number 3075 (torque at our 2nd gear entry point). If we get below that number with our new gear then we most likely are going to be slower. Lets take little bites of this thing and see what happens. I goofed around and finally settled on 2.54. This gives me 60.7 mph at 6400 rpm in first gear. And I still have more torque than I would have had shifting into second with the previous gearing. But now 2nd is all boogered and the entry point is 5000 rpm. I will need to let it out some too.
And that is pretty much how it goes. Doing it a few times and driving the results will help you get a little better at this. You will know when you are doing some good and when you are just pissin' in the wind.
