Data Analysis - Performance Tuning

[ASH]

Good day Fanatics

I need some feedback into, if a market for data analysis and analytics exists in the Performance Tuning sector. I see when it comes to dyno-runs, information is represented on a static power, torque vs RPM graph, so its always the most recent run. How does one compare it to a previous run, or log the improvements made in a tune or fitment of new mods? Generally one would have to look at both graphs on separate sheets of paper or on a screen, and try to work our what changed. Would the ability to toggle between stock, Stage 1, Stage 2, Stage 3 graphs, make life easier in any way for tuners or does tuning software already exist to cater for this? If software exists does it meet your requirements, can it be configured to meet your requirement, etc? Is the data that is generated overwhelming with a summarized view needed.

Just throwing it out there to get some feedback........if some tuners can offer some insights into process, drop me a PM.

If there is a need, I could look into marrying up the two interests I have viz. data analysis and motoring.

I have also included a poll, so please feel free to cast a yes or no.

Thank you

ASH

I've seen graphs overlaid on top of each other even for 'power runs' (KAR does it for instance and I have graphs somewhere) and many other logs also generated by tuners besides the 'usual' graph from dyno days or initial/final runs. Used a couple of tools on my Subaru myself as well. I think any tuner worth their salt (apart from the parking lot flashers and IP thieves) are analysing this data anyway. However I guess everyone uses different software and there might very well exist a need for this. The logs generated by cars these days can be immensely useful and I suppose not everyone is able to read these and interpret them properly.

Thanks there Llew. Appreciate the feedback. One thing that does happen when graphs are overlaid, is that they become messy and difficult to follow. Think of the data created from a stock Dyno run, to a Stage 1, then Stage 2, Stage 3 mods. That's 4 sets of power and torque curves overlaid on the same graph.

One thing I can do is show the progression graphically between each change in vehicle state or tune. It becomes easier to digest the data when you can see visually how the graph changes by selecting different vehicle states of modification or tune. Actually, I probably can show the entire history of the power and torque figures graphically across the vehicles entire modifications history, will just require a classification of the modifications done, on a single chart to digest all the data.

This can also form a component of a visual dashboard build that also highlights key metrics of the vehicle across its modification history.

If anyone has some sample dyno run data that I can use to build up a comparative, please share with me, I'll give it a bash to see what I can come up with. Also vehicle log data as well will give access to much more data to build up a platform to showcase. Hopefully in a vehicle log there is throttle position info, temperature, ambient, air fuel mix values as well. I'll keep the data anonymous and will share what I build up on the forum to gauge if there is any value in this to vehicle owners and tuners.

Hope to here from others out there :coolShake:

I think that this is a must for all tuners, being able to show changes is much better.

Yes kw numbers are great, but I for one would like to know how the car responds to changes, things like-

is it able to maintain the new requested boost
is the fuel mixture optimum throughout the rev change
small boost leaks that might have a negligible effect at low rev, low boost, but at high rev, high boost

i am just thinking out loud, but it might be that some owners are more interested in this than others. I have all the dyno runs i have done, but have no data logs

Thanks for the feedback. I think if the tuner provides the vehicle owner with the dyno graph and the data that is generated, I could provide a solution to track modification or states of tune of tune from stock. As you mentioned, it's for important to see how the car responds to changes.

If you can PM me some dyno data or graphs, I'll see what I can come up with and share the output with you.........Excel data is also welcome.

I will capture the dyno capture into excel format and send them to you over the next few days.

Thanks man, the more data you can provide the better.
If you can classify the data, that will help as it will help for a comparing different datasets. If you can give me a parameter eg. Date, mod1, tune1 etc. you want to classify the data by, I can sort it out.

I'm pm you my email address.

Thanks to all who took time to cast a vote.

This what I've been working on with some sample data I created.

Basically the scenario is, you have someone who has a stock vehicle, and has the ecu remapped a few times but has these dyno graphs for each run for each time a map/file was loaded. This scenario would be to compare each map to the stock settings. Also taken into account cost of the mapping, gains across rev range, best bang for buck (highest average kw/nm gain across rev range per rand spent). This file works by making a selection on the right, and all the values in the file and the charts will update automatically.

Let me know some thoughts, if guys can make suggestions which are experienced in the real world I can improve this. I've never put my vehicle on a dyno, so the process is an unknown to me, I've purely created this from my thought process to get something going.

Bump......any feedback guys?

still trying to take it all in :smilebounce:

I have my dyno sheets but i need to capture them in line with the mods or changes ....

 

[ASH]

Hey Sash, maybe send the Dyno sheets to me but maybe advise the mods done so I can classify the data. Also advise anything you want to see or compare? With these screenshots above you loose the interactivity of the dashboard, where you click the selection on the right and see how the graphs and values update with each selection.

Spoke to two tuners and there is definitely a need for this, it effectively bridges a gap between the standard analysis software a Dyno has, and additional custom analysis which a tuner wants to see. Also awaiting some data and some metrics from them which they want to analyze.

[sash]

Just captured the first few, which were in Hp and now realised the remainder are in KW....

i might just scan and send them to you
