ECU Tuning - 550Performance - CRF250L Rally CRF300L Rally - ThumperTalk Has anyone dealt with 550Performance (Facebook link is the only web presence I could find) ECU Tuning - Honda CRF 250 L MY13 - MY20 - 91 Octane Tune $79 99 Looks interesting and I would prefer a remap over a piggyback solution
Reflash the stock ECM!?! - CRF450L RL - ThumperTalk After reading a post on ADV Rider, that claims for $199 00 550 Performance will reflash the stock ECM to one of three tunes, depending on motorcycle header and silencer choices
550 Performance Reflash or Vortex ECU? - ThumperTalk I must of got one of the last reflash jobs done 550 received my ecu 3-13- 25 and I received yesterday in the mail Taco moto said my sx1 is in the mail after a second reflash
ECU Tuning - 550Performance - Page 5 - ThumperTalk From a performance perspective, the fueling now matches your bike's hardware set up Additionally, some of Honda's tuning for lowest common denominator fuel has been undone and, by so doing, throttle responsiveness improved Easy install on 17 and later bikes the ECU is under the rear fender, just forward of the tail light truly plug and play
Reflash the stock ECM!?! - Page 4 - CRF450L RL - ThumperTalk Also think it will be slow to get the older L owners excited about this Performance 550 reflash They either spent a lot on other stuff -or- conditioned to the "cry wolf" syndrome about all types of past L fixes that only offered limited benefits

Possible 550 performance ECU reflash issue - ThumperTalk New here, I've been reading and browsing but today I have to ask the tribe a question 2026 crf450rl I had my ECU flashed by 550 performance and had the time to install it today along with my exhaust and graves block off plate After everything was installed and ready I hooked my battery back up
Video: Air Box Mod - CRF300L Rally - ThumperTalk Consider a 550 performance side cover with frog-skin- as that is water resistant membrane that is a better design however the inlet snorkel needs modifying by cutting in half as the diameter reduces along its length Also look at Unifilter AU4138KKIT that removes the paper element and provides a high flow foam filter with over socks
More HP - CRF250L Rally CRF300L Rally - ThumperTalk Just get the 550 performance ECU do the air box to throttle body mod - the Unifilter mod and then tune the ECU - CBR300R cams and you are then likely to get 37-38 HP with the tuned ECU- FYI Stock CB300R is 34 HP without ECU mapped Check Jake the Garden snake did similar CBR300R cam and snorkel Mod - has not put it on dyno yet since though
