this is what I tune for

You can buy a speed limiter removal licence for the Maptunerx as well. It is cheaper than the full tuning licence

Nice. Have a customer with GTX230. We are at 81mph with ET137, 629 cam, retainers and springs with out of box VTech tune. Running 15/20 prop.

Have been using the vtech logger for 2 years now with no issues at all. Great bit of gear

What ski is that on Tucka? Have you installed an air intake upgrade?

All the customers I have done in QLD all run 98 fuel without a problem

Hi All,

I have an issue with a Riva Open loop kit. Kit has been installed with 160° Thermostat and been in ski for 2 years with no issue. Past 2 rides temp is fluctuating between 69°C and 78°C...

Has anyoe managed to run the update yet. Nothing appears to occur when you select on air update

hey mate what do you need. Feel free to PM me

Something is wrong with that setup. You need to get rpm up to 8700rpm. The skis I have done with those mods are seeing 75mph plus

You can just buy the reset service app for a reasonable cost. $40 I think

No need for VT1100 injectors. If wear ring and impeller are within spec than next place to look is carbon seal. If there isn’t enough pressure on boot then under hard acceleration it can suck air and...

Install retainers and just get your tune rpm limit bumped to 8700. You are better off staying with stock injectors with that wheel

Ha ha. All testing was done in Australia over summer so looking at air temps of 40° Celsius I saw about 3° Celsius max difference within the hull with no extra venting. Water temps of 27°c and...

No. it won’t be the same air intake temp it will be a slight difference of a few degrees. Not as much as you would think but.

No it doesn’t get VIN locked. I have used mine on about 15 skis to dial in tunes and not a single issue

There isn’t much difference within the hull on temps. Unless your bringing air in from outside it doesn’t matter too much where you pull air from for air intake. Within the hull I found that without...

The Maptuner platform is great. It’s not just “files” that are flashed, there is a lot of R&D that has gone on and collaboration between all parties involved. Then you have the benefit of...

Glad to here. O2 extension cable is way to go

Do a rear 4” intake. Forget the kanaflex. Put a set of 42 injectors on with a drop in ET127 wheel. That will have you moving. Simple cheap and fast. Afterwards go for a tune to really get the ski...

How did you get on with this build?

No you current ECU can be overwritten.

I had customer with same brand tune that had issues with timing pulling at WOT. Sent ECU back 3 times to try and fix it. All to no avail. Kept saying something else was causing it. He changed to a...

RXPXFREAK where are you located? As Moparguy stated run it static and forget reference line. What mods are you running?
