TDStuart Tuning Adventure

Heres my completed sheet with all RPMs set up in tabs, filtered +/-250rpm and MP19>90%. The lower RPMS didnt hit MP19 much so I filtered all that I could.

Looking through this you may see what I did.

Curves all go away from 100% VE at these angles.

I don’t see an attached sheet. Was the file size too big?

No, I am having issues with this web site constantly loading then freezing at 100%. Im zipping it and attaching.

If it’s over like 10k Kb it won’t upload. If you can’t get it to work just send to my email, I’ll dm it to you. I’ll update everyone what I’m doing wrong when I figure it out

That works I’ll check it out tomorrow and see where I’m going wrong

You recommended 25/50. There is no MP for that so I thought 20/40 would be close and it has okay driving characteristics. If you think I am fine rewriting a MP cam value or have another MP you would recommend let me know.

I recommended 25/50 specifically for the following reasons:

- It places IVC at the same timing as stock fuel economy mapped points such as 16 and 17, which are also max intake cam retard the oem uses.
- It full retards the exhaust cam. Comp pushed EVO very far advanced, which abbreviates the power stroke. You want it max retard to extend the power stroke as much as possible at cruise.

I mentioned starting with MP18 (30/50) and just moving IVO 5 deg to make it 25/50, then dialing it in from there.

I think I got it to work. I think I am going to try and make an automated tool to do it all.

Okay here is a tool to automatically do it. Extract the zip and open the .html file with a browser. Click choose file and select an hptuners log file in .csv format. It will open and start prompting you questions. It basically just asks if you need to filter a mapped point and what percent and above to filter for. Once that is done the options for rpm will appear. Enter a min and max rpm and hit update calculations and it will update the math for that selected rpm range.

I tested it comparing marks data he sent me and it was spot on.

How to use video:


Currently only accepts unedited hptuners .csv files

If anyone wants me to expand the files it can take let me know. If you know html&css feel free to make it look better, I hate design.

@markmurfie Let me know what you think of the tool above. If people want me to include other file formats I can add those aswell.

Also how are you choosing your rpm ranges? It seems to influence the output quite a bit.

Also once I plug this data in do I need to log again and do more corrections, or is this just what the car thinks it should be based of the TB model and its not going to change?

I just do +/-250, usually that covers the RPM point some places, some logs, require a larger spread.

This is making the calculated MAP match the estimated MAP from throttle body. It is always best to make both match a MAP sensor.

Okay so other than just getting more data the only way to further improve is to get a map sensor?

SD in a boosted application is a little different once in boosted areas.
There's the push back ratio of different cam angles that can limit the maximum VE slope, which can throw things off of not filtered out.

This is basics of tuning the SD model.

If the maf translation, tb model, and baro are accurate, then the tb-model map pid should be very accurate.

Didn't we have me set baro to 30?
