Re: ECU, map, dyno, tuning?

How is the FX450 cam..? That's maybe more aggressive?

Re: ECU, map, dyno, tuning?

While reading up about the vortex ECU I stumbled over this:

It's from 2011 and I couldn't find any other info about it. I wouldn't mind installing my backup injector upstream

U can make a custom map but i really don't know how.... maybe ktm map are more easy to find.
Sorry to bump ancient thread - but someone local has a KTM Tune ECU cable forsale and i thought I'd check here for anyone using it and found this.

Romain - did you ever test this?

Ive tried the program but on my KTM 450 EXC.
From what Ive heard you need to unlock the Berg ecu to be able to this while the KTM ecu is open.

It works to do moderate changes, cant remember the percent limit, but there is one. You can up and down fuel and ignition. There is a limited number of rpm breakpoints (like six, or some ridicolously low amount) which is a bummer but you can set each point to your preference.

I used to have access to a dyno on a previous job, so I tried the afr mapping on my 570 stock and it was very good at around 13:1 all the time.
So depending on what bike you have and if you made any changes to it you may or may not need to touch it, start by measuring where youre currently at.

On my KTM that I mostly trail-ride I took a bit of advance out on low openings and bottom end, for this it worked well.
Id say its not a proper mapping tool but more something you can use to forge your own personal power curve.

Thanks TT!!

I've got no access to unlocking ECU so that pretty much rules it out. Good info posted though

cheers!

I have a remap, Vortex and an EJK piggyback tuner on my three bikes.

All have been dynoed and the adjustables have been setup on the dyno.

At the end of the day the piggyback tuners do very well and are priced at a third of the Vortex. I dont see the need for 10 maps like the Vortex. The difference between maps while keeping the AFR’s in check just wasnt worth bothering with really.

The piggyback tuners can be adjusted as needs be and have good adjustment features. Run one of these with a map switch so you then have three timing settings. Job done.

Get the AFR’s optimised by dyno along with the map switch is all you will need. Then if you make system changes further down the road you have a unit that you can adjust.
Thanks from tourist
