Thread: TunerCode Overview

TunerCode includes all of the maps, tables, and scalars you will need to tune with confidence. You will know what each controls, how it works, and how it affects other aspects of the tune. Also, all of the parameters that are affected by the tune are data logged so you can see the actual results of a change. No more guess work and wondering what a table really does.

Exactly.

The TunerCode documentation comes with EVERYTHING you need to know about the tables that are available for tuning and honestly, it is much more than most people will ever even touch during the tuning process!

It takes the guess work out of what the table actually does and provides a great description of how the table affects the tune.

When using TunerProRT/NismoTronic with tunercode is the map trace function automatic? and also does maptrace work on all tables/maps like Nistune?

What is the link again for purchasing TunerCode. The website is still lacking

The map tracing with NismoTronic is automatic, but at this point it only does the main fuel/ignition maps and the VQ table/graph.

I "may" add in parameter table tracing but at this point it is only the primary tables that have map tracing capabilities.

You can contact Dave directly about purchasing the TunerCode package, his contact info is listed on the website.

TunerCode

TunerProRT with TunerCode is setup to automatically trace all traceable tables and maps. There are also some constants that have data tracing. For example, when editing the injector latency, the current actual latency is displayed.

Hey, i just came to a conclusion about a feature of tunercode that was puzzling me.

-Enable/Disable TPS fuel map load column contol

is listed in the features, but in the description list of flags when tuning, this is listed as

-Enable Alpha/N TPS limit.

I was trying to work out why no matter what i did, or what boost im running, the map trace goes to full scale on load with full throttle. Turning this flag off seems to stop this happening, but i can see that i will prob need to start my tune all over again to make use of this.

Maybe i just missed the part in the instructions that covers what this flag is for, but there may be others that have had this issue too. Be nice to tune for boost, so its not running 9:1 at 7psi boost if i turn it down. Clearly this flag is better left on for NA engines, but there may be advantages to some.

You're absolutely right, and I apologize for the ambiguity. This also points out one of the struggles I had developing TunerCode, which was what to name these "features" as I discovered them. Maybe "Fuel Map Load Column TPS Control" would have been better, as it is not actually Alpha-N in the classic sense. It only applies when the throttle goes above the values in the "TPS Limit for Alpha/N Mode RPM Table" based on RPM. (Alpha/N isn't exactly right either as it could be miss-interpreted as 'alpha divided by rpm'. Of course Alpha-N could also be miss-interpreted as 'alpha minus rpm'.) Suggestions as to what to call this feature are welcome.

I am also very curious as to why this would be better left on for NA engines, and/or the advantages to using it. I will be retuning a KA24E (single cam) with a fresh rebuild soon (which has this enabled) and was thinking of disabling this feature.

Thanks,
Dave

I struggled with the name for a bit, but after reading the documents and talking to you it made perfect sense.

Reason NA might be fine with it is because NA doesn't need nearly as much fuel as turbo. I know that on my Turbo B14, which had OBD2 Calum RT, I always struggled trying with keeping my AFR's lean at lower TP's with wide open throttle. It was not unusual to see 10:1 AFR's since there wasn't the volume of air at the lower TP's.

I was thinking as a NA doesnt change power as much, at full throttle the load is generally similar, although there will be differences between gears i guess.

Glad i guessed right what it does lol, i only played with it in the car with emulators and ignition on and watched map trace.

I think -Enable/Disable TPS fuel map load column control gives a fair idea, as when i saw that on the features list it suddenly made sense what -Enable Alpha/N TPS limit actually did.
