Shadow logger MS for Android

This just rocks!! I was seriously giggling like a little girl when i got my phone to wirelessly connect to the bikes ecu, show real time display, and record/upload to shadow tuner.com The days of big bulky data loggers are over!

Cool find Scott, it is pretty amazing what these newer smartphones are capable of.

I will add that there are some drawbacks, especially if you plan on using any of these functions with the GPS it will probably be less than stellar results. I am sure everyone has seen all these cars doing the 60-130mph runs, and I was curious how the bike would stack up. They make an app for Android that is able to time this, but the GPS on the phone could not keep up with the acceleration of the bike. I had the speedometer read close to 180mph and the highest the app/phone ever picked up was somewhere around 130mph.

But if you are only logging AFR, and ECU parameters, you definitely can't beat this.

I have a gps setup that uses a 10hz refresh transmitter and connects to the android via bluetooth. Need to test it at top speed, but i believe it will have no issue keeping up. It has logged at full resolution the harder accelerating lower gears, without issue.

were you using the bluetooth module or wifi? I have been reading about the cheap bluetooth mod for the MSx

Bluetooth adapter http://www.efianalytics.com/products/class1Bluetooth.html

I will also be testing the top speed recorder that a free speedometer app has as a feature soon (to test the GPS against the timing lights at the 1320)

I would like to see that Scott, it will be interesting to see the results. Like I said in my own testing I have found it to be lacking. But keep in mind that the MPH on your time slip may be a tad lower than what would register on a GPS because of where the clocks are and the fact that most people stay on the gas all the way though the traps. The GPS Shane has would probably do well because it has a high refresh rate at 10hz, I am not sure what the refresh rate is on a phone.

Everything I have found so far shows a refresh rate for my phone to be around 1hz, so there is a big difference. It could depend on the type of phone though.

What setup is that Shane?


Some stuff I posted on another board:

quote:
Based on advice from the board member Hobster, I picked up one of these:





It is a Bluetooth GPS sending unit. The basic problem with typical handheld GPS units is that they update so slowly, usually once per second. Meaning that you can easily get a reading that is inaccurate. I personally have seen this when comparing GPS results to data logged runs. Using the proper hardware and software combination, you can get some great results with one of these Qstarz units, and they will update at a 5-10hz rate. This will be a great data-logging tool.


Using a few datalogged runs, I was able to produce this simple spreadsheet comparison chart:





I was able to overlay the data from multiple runs and produce a line chart of time-to-speed roll-on comparisons in various gears. As with anything, being able to collect and analyze the proper data is key. The same holds true for testing methodology. All the data in the world won't help you if you don't really understand what it is telling you!


I don't have Microsoft Office, but I used OpenOffice instead...it is free, and mostly Excel compatible:


OpenOffice.org - The Free and Open Productivity Suite


In fact, due to $$ I am no longer using Microsoft Outlook either. Instead I use Mozilla Thunderbird as an email client:


Mozilla Thunderbird


It is also free. That will leave a little extra money for the bike hobby. :


Anyway, I am going to spend some time developing my spreadsheets for racing use. I have a friend at work who is great with Excel, and he said he will help me make some custom spreadsheets for analyzing my data.

quote:
If you have an Android, here is an application you might try:











Dynomaster - Welcome


This application has some pretty good features and the company has some other products as well. As onebuckwild said, there are lots of apps out there...just find the one you like best!


quote:
Today I wanted to do some more testing of the gps-logger. I decided to do an acceleration comparison of two different bikes, over the same stretch of road, with the same rider...within 15 minutes of each other.

I am not going to get into the specifics of the bikes/setups, but the results were expected.


I think these results illustrate two things:

1) Proper setup for the particular type of race is everything.

2) A smaller bike can easily trump a larger bike if set up properly.


Once again, the test was a 2nd gear roll-on. This time the speed range was higher, 40-90 mph:






In looking at the data, the litrebike reached 90 mph approximately .3s quicker. Now you may be saying that "3 tenths of a second isn't much". Well, let's take a look at how much distance you can travel in 3 tenths of a second, at 90 mph:


Litre ET to 90 MPH 2.9s
Bigbore ET to 90 MPH 3.2s

90 x 5280 = 475200 feet per hour

475200/60 = 7920 feet per minute

7920/60 = 132 feet per second

132 * .3 = 39.6 feet


Almost 40 feet in .3s!! Now, that is not exacly the distance that the litre would be ahead...there are other factors at play as well. But I think you get the idea of how significant it is. This is the kind of data that proves very valuable when testing. We are not talking about two different riders, of different skill levels, or on different days, or different conditions. We are not looking at just mph, we are looking at ET as well.

I will also be using additional calculations to shine even more light on the performance equation, but I am leaving those for the excel guru at work.


quote:
More GPS data...


The purpose of this chart is to illustrate what a huge effect weight can have on acceleration. This time a 2nd gear roll-on from 40 -100 mph:





Once again, the runs were made with the same rider over the same stretch of road. These pulls were made within 8 minutes of each other. The difference being that 150 lbs of ballast was added on the 2nd pass. The effects were huge.


In looking at the data, without ballast, the bike reached 100 mph approximately 1.1s quicker. What does that amount to?


Normal ET to 100 MPH 4.1s
W/Ballast ET to 100 MPH 5.2s

100 x 5280 = 528000 feet per hour

528000/60 = 8800 feet per minute

8800/60 = 146.6 feet per second

146 * 1.1 = 161.33 feet

Over 161 feet is travelled in 1.1 seconds at 100 mph. That is known in most circles as 20+ bikelengths. Now, in most cases you won't see a 150 lb rider difference alone...unless a 120 lb guy is trying to race a 270 lb guy (it happens). On the other hand, this chart serves to make clear how important it is to pay attention to the combined weight of bike and rider. With the extra ballast a 20% penalty in acceleration was exacted!

Anyway, time to hit the elliptical....


Sorry to threadjaclk, Scott!

Shane

Thanks for posting that Shane, that is the App that I have but as stated the GPS has to low of a refresh rate, I will have to check that one out.

I too apologize for the threadjack Scott.

Internal gps is like once per second. The qstarz transmitter is at minimum 5x faster.

Damn, that wont fit in my case.

Thanks for posting it up, I may have to mangle the bottom of my MS3 card to add this.

i have it on the end of the serial cable, unplug bluetooth adapter to plug the ecu into the laptop to upload the new map. im sure it could work with a laptop with bluetooth capabilities to avoid cables completely, but i dont have anything to test with
