i sought the advice of multiple people and was told i SHOULD get the YFZ450R 2020 if i'm looking for good specs at an affordable price so i decided to skip the newer models anyway. i have a question regarding this upgrade i'm planning for my YFZ. mine is still stock, all of it, so i want to install a vortex ECU. so how can i know if i have installed it properly? is there anyway there is a light indicator that shows whether it's working? and what setting should i select and is there also like a specific tell that it's the correct one? last and sorry for asking too much, what's AIS delete? what do i do with it?
 
if the quad is not starting, the issue likely lies in the system's installation or functionality. quads rely on precise configurations, so proper setup is key. the tuning maps included in the instructions are a great place to start. based on specs and everyday use cases, map 4 could be a solid choice. from there consider your elevation and begin with 7, 7, 7 for low, mid, and high throttle settings. this gives you a balanced starting point while keeping the engine within safe parameters. monitor throttle response at various RPMs and fine tune as needed for optimal performance. the 7, 7, 7 setup is unlikely to cause engine damage but leaning it out might improve efficiency.

the AIS delete system is another interesting feature to consider. this setup removes emissions equipment that recycles crankcase gases into the intake which can improve engine performance by venting those gases out instead. it is affordable at around $20 but pairing it with an oil catch can such as one from Peak Racing is highly recommended. this addition helps to maintain a cleaner intake and reduces the risk of oil buildup. the tech behind these mods makes for a more responsive and efficient ride so it is worth exploring
 
there isn't a specific light indicator per se, but you can test it by checking for a change in performance. Once installed, it should run smoother, with better throttle response. You'll need to tune it based on your mods, there are default settings, but adjusting for your air intake and exhaust is key. AIS delete is for removing the air injection system, which reduces the risk of backfiring and keeps things cleaner.

Agree with what both @yamahahaha24' & @Veronica.sims002 are saying. Quick answer: just see what happens after the Vortex ECU installation, pick the right map fitting your riding style, then do AIS delete for your engine.

Great choice going with the 2020,it's definitely a strong option. I've got a Vortex ECU on mine as well. You won't see an indicator light, but if it fires up and runs smoothly after you calibrate the TPS, you're all set. I started with the trims at 5-5-5. Regarding the AIS delete, it really tidies up the emissions stuff and can help cut down on backfiring. I did it and haven't regretted it since.
