Troubleshooting GPX FSE300R ECU/Pulling Diagnostics

[@bobkelly2447]

THANK YOU for this video ! I have a CSC RX4 and am trying to get to the point you just showed make a log file so I can see what it's actually doing..... and you showed that ! thank you so much !!!! it's not like I had a problem with my bike at all, it just has a fast idle and misses a bit at idle.... but that is real easy to over look.... but I know it can be better ! my J2534 adaptor should be here soon, as the cheap one from china does not work at all so I got the one that he recommends in HUD ECU HACKER..... the cables are of utmost importance ! they have to work or your just spinning your wheels ! I thought I could make a log file fairly easy but I was not sure.... NOW I KNOW HOW !!! because of you ! thanks buddy !

Thanks for posting this as I have a feeling it's going to come in useful for my 450 that I've just got that's running very lean.

Hi Sam, what app did you use on this? Got my fse300r just over new year. Came from a wr250f, and i just feel like the power snap wasnt there in low revs. Is there a way to counter this?

Did you check the voltage at fuel pump level ? Is it a Lithium battery ?

[@SCakey]

It is a lithium battery but think it's all my air/fuel during startup until it learns a few things. This bike is running a different map than originally and the new map created this.

@@SCakey lithium need to be wake up at "cold conditions" during several seconds to get the max Voltage and ECU can trim a bit also for its own needs and so fuel pump do not make its job. Relay with direct power from battery could also be a possibility depending on yout observation. It is visible on "mt05" bikes
