I am here to help

I?m tuning my seadoo it?s a 2012 Rxtx 260 I removed the limiters. I set rpm limiter too 8400 rpm for now. I have a 90 degree air intake on it and a free flow exhaust. I?m hitting 75 mph with three bars of gas in it. I still have to do intake manifold upgrade and set slip on supercharger to 11-12 ft.lbs is there any tuning where I can get more out of it with ignition timing and fuel mapping. I have to put some air vent holes in it still too where would the best place be to drill them. Thanks

I am still struggling with transposing 170 values into the 130.

2023 gti 130

I copied all of the timing tables from var0 (most advanced) to all of the other tables

I copied all of the x and y axis values, as well as table values (var0) over to all of the other variants for pe lambda,

I removed all of the torque limiters (secondary) anywhere I found them I set them to 100%.

Ski runs like a 170 up to exactly 7400 rpm and 50 mph and hits a wall.

Am I missing an rpm limiter?

If I post the file, can you take a look and see if I missed something, please.

Would like to start tuning a 2014 RXPX Riva stg 4 with HPT. It is currently tuned with Maptun by Riva.

Does the stock file have to be loaded back into the ECU prior to reading with HPT? My limited understanding is HPT does "not" save the stock file it provides a new base line tune file. It is not easy to have the stock flashed back into the ECU. I do not have the Maptun programmer.

[Swampdonkey]

HP Tuners mpvi3 is a virtual read, so it will recognize the hardware/software (operating system) combo and fetch the stock file from their repository. If you "read" your current ecu, you will have a copy of the original tune for that ski.

Stock file will need to be flashed back in and start from scratch. HPT will not recognize the Riva file. They use Winols and even have a "no read" tag in the file so others using Winols cant read them either. Pretty easy delete though.

This seems reasonable, Maptun is very sensitive about this. Your comment "Pretty easy delete though" what does this mean?

[Swampdonkey]

You wont be able to read the Maptun file, but when you get ready to flash the .hpt it will erase the Maptun file immediately prior to writing the .hpt.

if he send me ecu i could pull the file and post it here so everyone could see riva tunes are not as reliable as they claim tO be

Do you use MLVHD to tune these engines?

Does anyone have a stock 300 tune that they can post or email me. I would love to see how Sea-Doo has these set up. Things like what do they do to the Eco mode. Is it just the DBW settings or do they play with the Target Lambda table?

no we use HPT VCM Scanner

ECO mode just limits rpm so you don't go into boost.

I have a turboed spark. From what I gather from here already is there is no issue flashing the original file with HPT over a previously tuned ecu with Codeshooter? My CS device is a paperweight currently so cant flash the stock file back.
