Hp tuners screenshots

That doesn't make any sense. The first thing they always start with is pulling the base tune from the ECU.

From the looks of it the ECU is only read to get identification which is then used to fetch the matching firmware from the server. You then modify the remotely fetched firmware and write it to the ECU.

HP Tuners is unable to pull the tune that’s already uploaded. If you have a RIVA tune or any other tune on the stock ECU then HP Tuners will be unable to read it. You will be provided a stock tune file from the HP Tuners server to modify and write to your ski.

But
That’s not what their support website says. There’s no place it says it downloads a tune vs pulling the data from the ECU. It actually says it pulls the data from the ECU and then opens that data in the software. What would happen if you tuned your ECU using HPtuners and then your laptop crashed and you got another laptop? Would you have to rebuild your entire tune from scratch? There’s no way to pull your modified tune off the ECU and resuming tuning that file? I think it’s obvious how that’s less than ideal.


Why would you pull the stock tune from the ECU and then save it as a backup in case you wanted to restore it, if there were always stock tunes on the website/server?

They didn't have my stock tune file, so I had to mail them my ECU. Anxiously waiting for it back...

This is a general set of instructions and every application will be different. I'm able to read the modified tune on my Corvette but it won't on the Sea-Doo. I have a MaptunerX tune in my Sea-Doo and it won't read it nor will it read a tune that's been modified using HP Tuners. I'd agree that this is not ideal.

if I had known it was like that I would not have ordered the interface, a spend 580$ for MPVI3 + BRP cable and 4 credits for have a stock tune...
So i'm going to have to recover all the data from my ECU with DIUS tune, but I don't know how I'm going to do it.

On the HP Tuner website he talk about Tune Translation for convert a log .bin file to.HPT file, and it cost 50 tokens

Upload your binary files and download converted .hpt files to use with our latest version of VCM Editor. Tune Translation allows for binary conversion for many controller types, most costing 50 tokens but certain controllers are free of charge. The full list of supported controllers and costs can be found here.

How Do I Use Tune Translation?

1. Navigate to Tuner Tools by HP Tuners.
2. Upload your .bin file.
3. Once Tune Translation completes the conversion, click the “Download” button for your .hpt file.
4. You will be prompted to confirm the consumption of 50 tokens (if applicable) from your account.
5. Open the downloaded .hpt file in the latest version of VCM Editor.

hi guy i'm very happy because i've used KTAG interface and KESS suite for extract the MAP from my ECU, you can copy all the ECU or separate the map than the eprom
I upload my .bin file extract from my ECU : map only
I paid 50 tokens for use the HPT software Tune Translation : 50 tokens cost around 113$
And i've received my .HPT file and this matches my current tune

there is new variants ( on stock HPT file RXP X 2022

[ptscon]

So what do you do with these variants? Just set them all to the same value?

I think there is a bug in the decoding process, in all the others tables there is at the max 4 variants
Of course i raised all the speed limits

No, firmware was updated to have additional limiters.

Old firmware has 2, sometimes 4. New can have the 8. Also some maps change 8 bit to 16 in some places. New compilation by Bosch. Like a "V3" build.

May have "2 variants" for group of 4 limiters for different conditions and or end of line configuration (RXPX, RXTX, GTX, etc)

You forgot the most important one AFR. How is it adjusted. That what we want to know!!

It's always best to put the tune back to stock when switching tuning platforms. Different systems don't communicate the same as others, different code...etc. Put your ski back to stock tune before you attempt to utilize this or any other tuning platform. However once you tune with HP it will read the tune and you can make multiple adjustments from there

[Tbranella]

You forgot the most important one AFR. How is it adjusted. That what we want to know!!

most popular way is to use the injector pulse width multiplier (same thing you would adjust if you were using Riva Map editor)

or you can use the VE tables.. but you don't want to make drastic changes to the VE tables.
