2012 RMZ250 Fuel Injection Management Systems EFI Reviews

Recommended Posts

Hi, I ride a 2012 RMZ250, I'm going to replace piston with a high compression 13:9:1 and replace full exhaust system with FMF power system, problem is will i need to remap or dyno tune fuel injection system? Some say go Power commander and dyno tune, cost about $900, others say buy tuner off ebay say JD power surge tuner, Wiseco EFI tuning, MX tuner box, Bazzaz box etc... ???? what is the best system to buy do I need to buy tuner or should I just use the plugs that come with the bike white or gray plugs, some say go for the richer plug? some say you can put on the FMF pipes, high compression piston and do nothing the computer system will make allowance and adjust itself?

Can someone help and give me some advice so I can get the best out of my bike

Thanks

yep, agree

contacted two susuki dealers, both use MX tuner box, one dealer will adjust then you take away, if not happy with adjustment, they will adjust until it feels right, at a dollar cost each time. The of dealer uses the MX tuner box but said it a waste of time unless you dyno tune it as well. Rang a motox tuner who will fit a Power commander and dyno tune for $900 (only after you fit high compression piston and after market exhaust system, motor upgrade etc...) to get the most out of your bike.

Another mechanic said your better off putting your money into skills training, riding techniques on how to ride your bike better. You can put thousand of dollars on the motor etc... and only gain 5 seconds and with training techniques you will gain say 30 seconds. Example you can put Chad Reed or James Steward onto a stock bike and they will get the maximum potential out of the bike and go faster then anyone else with fully blown bikes because of their riding skills.

So im putting money into riding skills/techniques but agree if adjusting fuel injection you must make sure you dyno tune. All those FI tuning kits only make you think its better, you will never get it right unless you combine it with a dyno tune.

If he does not re-map his FI and iginiton after modding anything on the bike, it will run like crap.

Riding is not all about going faster. It's about having fun. If you bike runs like crap, it's not fun.
