I've got the Lifan ECU Flasher Software for all Lifan ECU Models!!!
 

It supports full tuning of the ignition and fuel curves, so I looked up a local Dyno Tuning Company that brings their Dyno Trailer by events at Deals Gap. I've got an Aluminum Intake and Slip-On Stainless Steel Exhaust, so whatever they create for a fuel map should be universally usable for most Lifan X-Pects. If anyone else wants to build and share their ECU Tunes it'd be cool to see what we come up with. Anyways, here's the Lifan ECU Manual with the Free ECU Flashing Software.

Also, here is the Lifan ECU Reflashing Software Guide along with the cables.

Thanks. :tup: I've downloaded the software. Now we in my world. I love tuning ECU's just to see how much power I can unleash. Now all I have to do is wait till my KPX250 arrives. :yay:

Holy crap!!! This is amazing! Thank you for sharing.

Now do Evinrude etec motors! Lol

Wonder if this will work with the Lifan 168cc EFI scooter engine? May try it one of these days.

If it uses the Lifan EFI 9 Euro 4 ECU then yes.

The only information I can find on my EFI is that is a HUNIER EFI 9.0 A200624. Google Hunier and you come up with nothing useful. I have ECU hacker and the interfaces required by have still to figure out how to use them. same with the Panlong bluetooth scanner. Does the Lifan EFI have a Lifan marking.

I do see where they added the 'Lifan EFI 9.0' xml to the newest version. Have you tried the newest version of hud ecu hacker? Which bike do you have?

I'm also wondering if you can change the mappings like you can with the MT05/05.2 ECU.

Teklock, that Hunier EFI is on my 2020 Lifan X-pect. I downloaded ECU hacker about a month or so ago so guess it is the newest version, I have hooked the bike up to ECU hacker and chose the Lifan ECU and I connected and saw some information there but have not recorded anything so far. I have not figured the program out yet and don't really want to leave the bike idling too long while I play.

How do you down load the ECU flashing program ?

It's towards the bottom of the page under Download and installation.

You may need a J2534 compatible adapter like the Tactrix OpenPort adapter (or clone of it). The author of 'HUD ECU Hacker' is a member here. His name is Raptorix. Look up his posts for threads with a lot of good info.

Teklock, I have the VAG KKL adaptor which works fine. It is just that I do not know the program and its operation so hope to pick up bits and pieces as these threads continue.

It does look like the x-pect has the 'Lifan EFI 9 Euro 4' as listed in hud ecu hacker. Can you select 'Download entire flash' and actually download it? I'm still a bit skeptical we can do this with this newer non-MT05 ecu.

Thanks G-Raptr! I am sure these are leaned out upon arrival to get by import standards, and having no access to these adjustments is the main reason to go analog (carb). Getting into this is nothing short of game changer :tup:

Hooked up my computer to the ECU and connected started recording a logfile and went for a short ride with the computer in a backpack. First of all a note came up saying that the ECU was primitive and only refreshed every second. When I look at the dashboard I can see movement in the engine speed, see the engine temp and all sorts of other useless information. Of particular interest is my altitude of 1533 meters when in actual fact I am not much more than about 20 meters above the chesapeake bay. Also the play logfile has me down as a Lifan CTS 125cc xml whatever that is. Still in the dark here can anyone add some light.

I'm not sure what you are trying to do. If your intention is tuning, you need to be able to download the complete flash. When you select 'Download entire flash' does it download a bin? If it does post it here.

I would advise reading all of the 'help' docs included with the app. It tells about the xml file and how to fix some of the "errors".

If this works like most programmers I've used, you download you stock file to your PC then edit that file to load back in the ECU. It's not a can tune like hand held tuners.

That's how I imagined it to work as well. I haven't seen a stock flash/bin for this Lifan ECU so hopefully it will download it but I'm not holding my breath.

FYI- The altimeter function may not be calibrated, but it will still respond to changes, which is all that is important. The refresh rate is slow, but the programmed enrichment curves respond to throttle position and rpm, which are continuous input (not reliant on the sensor refresh rate). Things like temperature and altitude are affected by refresh rate, but they change slowly anyway.

Regarding the tune file, yes, I am sure that you load a modified tune file, just like I did for my Turbo diesel VW. So what you need is a tune file to load into the ECU. Either get one from someone, or if you can (like Jerry sez), edit your file on a computer and then reload it.

Well hopefully once we all start tuning someone will have a tune developed that they can share with everyone. I know i will for the KPX 250.

I agree, this is going to be awesome if it comes to be.

ps I had a KPR shipped out via RL carriers from the LA area and was scheduled to be delivered on Friday. Well today the tracking was updated and it's out for delivery so you may be getting yours early as well!

If you look at post #1 and the ECU hacker dashboard you will also see his altitude at 1533 Meters so something does not pass the smell test. At present I am trying to figure out how the system works before I try to tune anything. Has anyone taken a look at their Lifan X-pects ECU and seen if it is the same as my Hunier Hunier ECU, The ECU hacker dashboard has a list of ECU's one of which is a Lifan for some 125cc bike so how do we know that it is correctly reading the parrameters of the actual Hunier on the x-pect.

To add another thought, if the ECU was computing fuel ratio at sea level how would that change at 5000 ft would it be richer or leaner. I would guess that there would be less air and then less fuel to keep the O2 sensor in its range.

Until the logfile xml file is adjusted (in the logs folder) to your exact bike I would expect some of the prems to be incorrect. The important part is being able to download the entire flash to a local bin file that you can edit.

Well coneected again this afternoon, altitude now showed 5 meters which is more like it. Tried to down load the the flash memory and it came up with " this feature is only for the MT 05" by the way my ECU hacker is the 4.6 version.
I am trying to find out how to change the XML files.

Thats what I was afraid of. Unfortunately, we won't be able to tune these newer non-MTO5 Lifan ECUs.

I am sure sooner or later the information on these Hunier ECU's will get added, although at this stage maybe gettin a good carb fitted to the X-pect could be an option.

Didn't realize the Hunier and Lifan ECUs were different, we still have some options.
 

While it's not as tunable as a full ECU Re-Flash. If anyone else just wants Air/Fuel Ratio control after modifying their EFI Lifans. Then you can easily use a EFI-Enhancer that modifies the alternating voltage of the O2 Sensor within 12.7-16.7 before it goes into limp mode and thinks the O2 Sensor is dead. Anything more will require an Openport 2.0 Re-flash of more aggressive fuel maps. If you want to modify the Ignition advance without causing interference with the vacuum advance system then you'd have to modify the Intake Air Temp Sensor alongside the vacuum advance system which can rest at -8 Degrees before TDC at idle and climb to +17 Degrees After TDC at 9000RPMs. Since it's fuel injected and the ECU runs the ignition advance curve, you can't just put a performance CDI on it to keep the ignition advance from flattening out at 5000Rpms. For that you'd need a Magnum Dyno-Boost Module to manipulate the ignition advance alongside the vacuum advance to keep it from flattening out and of course EFI-Enhancement for Air/Fuel Ratio Control.

So for under 50 DAI you can get a good EFI-Enhancer.

Though a Magnum Performance Chip will cost you 300 DAI, though the reviews are great.

Either way, you'll have full Air/Fuel Ratio Control within Limp Mode Limits.

I’m interested in being able to tune my Vitacci clash 168cc efi scooter. Can anyone help me out?

Pretty awesome if it does what it claims, others try this? I might...

This is awesome. Anyone know where the OBD plug is located on the KPX250?

how has this been working to get more power or is the program is good like it is. ???

Jerry you've been a great resource since I bought my first China bike and found this forum, THANK YOU! You wouldn't happen to know if the KPM200 works on that ECU or not would you?

Kpv 150
 

Hi, is it worked on lifan kpv 150
https://ibb.co/52jfBj0

In theory this could be used to program the KPX250? I'm interested in doing some basic mods like a new exhaust to get a little more power out of the bike. Aside from the popping on decel and weak idle, my only complaint about the bike is the RPMs run just a bit too high for my liking at highway speed. The buzzing at 6500 is a bit gnarly, and I don't like cruising for long periods at 90% of redline. I understand the stock bike might not handle a sprocket change very well, but I'm thinking if some performance mods could squeak bit more power out of the bike then that along with a new sprocket could have it cruising at 65-70mph at 6000-6500 RPM instead of the 6500-7000 it's doing now.
