Fuel injection

[BloodFX]

Hi I was wondering is the ecotrons kit the only way to FI an old 250ee or can parts be swapped from the FI model onto the old models?

Ecotrons is worse way, low-quality and nothing but trouble. There's A LOT more needed in parts and labour than what's included in their kit. Best path is Microsquirt. One major component is software and using it to use tune. Download both and try it out.

Check out greg737's Microsquirt EFI on Ninja 250 and Bandit 400.

There's also buying Ninja 250 EFi components from Europe & Japan and converting bike into foreign model.

So at end of your post you said about buying efi parts from europe and japan, are you say parts are swappable?

Thanks!

Yes, it can be done. Very expensive out of all options. And you won't be able to program ECU until you buy additional software. Parts list includes following but I may be leaving some stuff out:

- wiring harness
- ECU
- flywheel
- airbox with IAT
- MAP sensor
- ECT sensor
- throttle-bodies with TPS
- injectors
- ignition coils
- tank & pump
- petrol hoses & fuel-filter
- gauge cluster


What is measurable goal with converting to EFI?

I just hate carbs lol.

If you're keeping bike mostly stock with no need for programmability, then factory system is simplest to install. No wideband-O2 or dyno-tuning needed. Truly plug-n-play.

Good resource is http://cmsnl.com to find part# of EFI components for foreign bikes. Then search on part#, can find on eBay.co.uk or auctions.yahoo.co.jp .

Its an el250, will the side swung exhaust affect afr?

Did pregens ever come stock with FI or do you have to look at euro model 2008+?

Shouldn't be a problem.

That's pretty cool work!!

ECU needs accurate measurement of intake air-temp, so you can remove air-box. But needs a place with steady and stable air-supply from outside for IAT-sensor to measure. Need to keep it from getting battered with hot air that's swirling all around engine area.
