If you buy an off the shelf ecu for a ktm/husq/gg 450 does the standard map switch become obsolete? I have a gasgas 450 and am considering ordering a standard vortex to see what kind of difference it makes but want to make sure it will work well as is, I don’t have a map switch since it’s a gg which means it’s set in the mellow map from stock. Will that matter once the vortex is plugged in?
Thanks.
Thanks.
Also, you can send any Vortex to Twisted Development and have their maps installed...for a fee...of-course.
Btw, I believe the KTM/Husky/GasGas stock (optional on our GGs) gives you more curves to choose from than the Vortex switch provides?

There are 10 maps settings available on the vortex , but in reality you will only use two or three at the most.
Most tuners sell different maps for different conditions- altitude, deep sand, less engine braking, special fuel, etc.
I use the Vortex from XPR racing in murrieta .
I think all new 4-strokes, except Yamaha will work….
Have you tried this ?
I removed the stock mapping switch and installed the Vortex switch on my 350.
The Vortex switch is much cheaper than the OEM switch.
However in reality I only use 1 map
Thanks for the clarification 👍🏼
I ended up sending my vortex to Jamie at Twisted Engineering and it definitely made a difference. Mine is a mx only 350, but I did have the same ECU on my 500 and had several maps to choose from, one being an aggressive map that I’d switch to, when I took it to the track a few times. It was way to aggressive for trail riding, but it really uncorked the bike at the track
If you dont want to use the stock KTM map switch with the vortex I think I saw that they have their own switch available as a separate accessory.

2. Do you still have Traction control option with Vortex?
3. Opinions on best map setting for map#2 ?
I know everyone is different and conditions play a role. I”m just curious where most guys end up with the settings. I will be playing with the settings obviously just looking for some input on where to start. Thanks. Stock 22 KTM 350 SFX T4 fuel.
1. Yes. any time you change the parameters of the Vortex you have to confirm using the TPS protocol as described in the Vortex instructions.
2. Yes, TC still works as normal using the OEM map switch.
3. Map selection is a personal choice - It depends on who programmed the maps into the ECU for what purpose.
It is also important to make sure your bike is not running too rich or lean, using the three fuel trim screws on the ECU.
We raced our 2022 250 SXF at the last National round at Hangtown using standard fuel trim, and then our motor builder told us that the bike was running way too lean using race fuel. Standard trim is the # 5 setting, but be prepared to go richer if you are running race fuel, or if you have a power flow air filter installed.
Each click of the screw upwards from the zero trim setting richens the bottom, mid, or top end by 2.5 percent.
Tuning these ECU's to suit the rider is the biggest performance tool you can ever have for the bike. Take a day and run through the maps and ride the bike to see how it feels, you won't regret it.
The first is to ride the bike, and try all throttle settings from just cracking it open to WFO. if you hear detonation and mis firing when you are wide open, that is normally an indicator of a too lean condition. If the bike is rich it will feel sluggish and boggy like you have a really dirty air filter.
The second way to see if you are too rich or lean is to examine the carbon on the valves. if they look like this , then richen the vortex:
if it is white or really light gray like the valves here, then you are probably too lean - Thats how our engine builder found our lean issue.
If you are using any more than pump 91 Octane ( and if you, do always use Chevron 91) then you probably want to turn the trim Vortex screws one more click toward the rich side for mid and top end and see how the bike rides.
One more thing, if you are using race fuel and no backfire screen on your filter, make sure you use a filter that is flame proof, like a No Toil Super flow or something similar. If not you could be asking for trouble if the bike ever backfires.
What is your map 2 ?
Do you know who did your maps? That is a pretty cool option if you have 3 maps available at the stock map switch..
KTM right?
Guess I’ve been extremely lucky on all of my bikes, I’ve never touched the TPS and every bike runs great. CRF250/450, RMZ450, SX 150, RM250’s. EXC500, SXF350
Jamie never mentioned it, Yosh didn’t mention it, Frenchie either. Have I been missing out on something? I feel like I just found out my girlfriend has been cheating on me.
