Thank you guys for all the work and effort you have put in to make it possible for beginners to understand the working of the mt05 ecu.
I have a MT05 ecu in my 50cc scooter from Riya motorcycles. What i noticed is that the ECU in my scooter is a Rongmao MT05 ECU instead of a Delphi MT05... The software for the Delphi works on the Rongmao MT05 as well. Maybe it's a clone or a rebrand. My scooter has a ECU limited speed (25 km/h) and i am trying to bring it up to 34 km/h. Unfortunately the manufacturer does not answer on my emails so i am trying to tweak it but as of now, i have no idea where to start... I used the PCHUD software and managed to increase the IDLE rpm speed using slew outputs. > Is there a way to find the ID of the max RPM speed so i can use it in a slew element to increase this max? > Is there a way to store this slew element in the memory of the scooter as well (flashing/remapping)? I will be glad to keep you up to date about this project :) |

Hi tere
Is there anyone know where to find the “Short term fuel trim” and “Long term Fuel trim” on this PCHUD program ??? Is there any place where I can find the following figers from PCHUD explained??? Engine Speed - Engine Speed Battery Voltage- Actual battery Voltage Coolant temp – Actual Coolant Temperature measured in thermostat housing Intake Air TEMP- Intake air temperature measured by MAP sensor Pump Duty Cycle – measured in percent Spark Dwell time – length in time of spark IPACV- ??? Exhaust temp - I gees measured by 02 sensor Air Fuel Ratio – Air Fuel Ratio 14,71 / 1 in perfect world Target A/F ratio - ECU is making this Target for Air Fuel Ratio BLM LEARN VALUE 1- ??? CLC INT LEARN V 1- ??? Fuel Pulse Width 1 – how long time the injector is injecting fuel DESIRED IGN TIMING- ??? CCE1 - ??? CLC CORR COEFF1 - ??? BLM CELL NUMBER- ??? DYNAMIC SA- ??? Fuel Pulse Width 1 – how long time the injector is injecting fuel DESIRED MOTOR STEPS – location of the valve from 0 – 132 IDLE VOL LEARN VAL - ??? Desired idle rpm – ECU is trying to achieve this given value Idle RPM error – difference between ; Desired idle rpm and actual idle rpm 23 ERROR counter- ??? Atmospheric pressure- actual Atmospheric pressure Current fault code - Current fault code which has occurred Historic fault code - Historic fault code stored in ECU Measured MAP – pressure in kpa measured by MAP sensor in throttle body but not sure way is so low EXPECTED MAP- EXPECTED pressure measured by MAP sensor O2- Voltage – voltage which passing by O2 sensor depend on amounts of oxygen in exhaust gases Throttle Position- actual Throttle Position Throttle Value- not sure Thank You |

Re configure your PCHUD to use
k_FLAP.hud dated 10/1/2016 K_FLAP.par dated 16/01/2002 These I believe were the last hud & par files I did. Below is an image showing the layout of PCHUD in this configuration and a corresponding explanatory list. the list is the best I could do at the time and I think it should answer some of your questions. (the image & list can also be found on post # 107) Attachment 14597 Code:

Thanks katflap
Thank You for You help You always representing the World class No 1 in servicing Zongshen RX-3 We definitely will mist You from this Community :-) Good luck with you new bike :-) Sorry I haven’t seen you post No 107 |
benelli RFS 150i remap
Hi all,
Im currently on a project to remap my bike ECU, tried to download PCHUD but failed to run the program on my laptop. Ecu harness also hard to find Anyone can help? |
Quote:
I can supply the cable as well - unsure if it’s cool or not to share Katflaps files? I do have those but it’s not my work |
upload files again please.

Could I upload the files again, the link does not work or, otherwise, my email is dani.mazabuel@gmail.com? Thanks again. |
AJP PR7 idle issue
Hi,
I have an AJP PR7 motorbike that has the exact identical MT05 ECU and uses PCHUD for diagnostics. As I live in an area without a dealer less than 5h drive away I am trying to troubleshoot an issue myself. Could someone shed some light why my bike idles inconsistently and also dies at idle speed ocasionally? Here's a video (I am having difficulties running the PCHUD program, it keeps disconnecting, I can only have it connected for a few seconds and then all values disappear and COM port times out. I have to switch to a different USB port and another COM port then it starts working again for a few seconds. Could it be a poor electrical connection somewhere? Bad cable?) https://photos.app.goo.gl/2BZ3CuCVduGWG8Yz5 Things I have done already: 1. replaced the O2 sensor with brand new 2. cleaned the throttle body along with the IACV motor 3. tested fuel pump pressure 4. tested and cleaned injector 5. replaced fuel and air filters The bike only has 4000km and is not even a year old. An additional symptom is that the bike does not run nicely when riding at constant speed, let's say 4th gear, 3500 rpm, it feels as if it looses powercycles occasionally. When full throttle, bike goes fine and really strong. |

Exhaust temp is not measured. The bike only has the O2 sensor in the exhaust. |
Yep data looks fine but so did my bikes and map solved the issue
Same poor running cond below 6000rpm as you |
@ spuzvica,
Just passing through & read your post. I noticed in your video you have the 'IACV lost step' illuminated, this should not be. see post #168 for some reference. Try resetting the ECU to clear this One idea I've read is that this can happen if your battery is not so good & is low on voltage (below 10v) during cranking or perhaps a slightly intermittent power supply or 'earth' to your ECU or stepper motor. intermittent ECU power/earth could also explain your bad connection to PCHUD via the diagnostic port. Regards :) |

I will investigate the grounds on my bike and let you know! Thanks for the tip! |

Have you found a solution yet to adjust the ecu from rongmao? I have the same problem. |
Hi guys. Am using Scomadi TT125i with Delphi MT05 ecu. The problem now is my engine temp is quite high, the idling is not stable (sometimes below 2000rpm n sometimes it could goes up to 2600rpm), frequently dies during idling and sometimes while riding the bike. I was thinking of remapping since it got so much problem.
