Re: cant upload cal to ecu
We are investigating the issue. The problem is related to voltage and it would appear to be specific to the TSX . Honda's ECU programming procedure recommends attaching a battery charger. Increasing the battery voltage while programming helps reduce the incidence of the WEN error. Could we get an indication of the year of the TSX that this problem is occurring in?

Re: cant upload cal to ecu
I found few of your posts bout this error and that low voltage is the problem so I fully charged my battery and connected Ctek charger on top in a power supply mode. Cant imagine more stable voltage situation in my case, I even never start engine after charging battery but nothing changed, WEN error.
The only way i can flash my ecu - engine run for 10-15 mins, no matters idle or in a regular drive. Interior heater must be on, without it i cant flash even after 20 minutes of engine run.
Please exclude wiring problem out of your investigation, its 10000% not wiring problem.

Re: cant upload cal to ecu
Yesterday i had to flash multiple cals to make few datalogs. I run my car , then stopped to upload new cal to flashpro or ecu, again and again. I can clearly say now that its really voltage issue coz everything else was constant. Leaving car with headlights on or rear window heater on for few minutes with engine off is enough to drop battery voltage to get WEN error , then 3-4 minutes of idling with everything turned off is enough to bump voltage for flashing. I bet 5 bucks that its not a flashpro problem, it maybe some kind of ecu fw routine to check voltage before it let to flash. Maybe you can find that code and patch it , im not gonna flash my car anymore after i finish tune but now its really annoying.
Re: cant upload cal to ecu
This problem get worse and worse , today i wasnt able to flash my ecu after 30 min run. I also tried to flash with charger , checked voltage on battery pins - 14.4 volts , when i turn ignition on it drops to 11.9 - 12.2 and still WEN error. Hondata , please find why it happens with tsxers and solve this if possible.
Re: cant upload cal to ecu
It looks like a soldering issue :) that i had on my Pioneer, when after night in winter -25 Celsius i start a car and start my cd player it plays except left side speakers when aux input is enabled, if i switch to radio or cd than everything plays correctly. I warm a car, turn heater enable aux on pioneer and started to wait, that after 10-15 minutes when it is warm in a car, with a grinding sound left side speakers started to play and after one minute everything played great! I have checked an aux cable ten times everything seems was right, i have cut a part of it and re soldered it, then the problem dissapeared. :))
Re: cant upload cal to ecu
Any one tryed to heat ecu or flashpro with a hairdryer ?

Bard, do you experience just the same issue ?
if so, pls post your data
Re: cant upload cal to ecu
No cause i still using k-pro dual harness, i do not have an ability to flash ecu to my vin, here is no Acura or Honda dealer or some one else with scanner.

Re: cant upload cal to ecu
my ecu is in recovery mode and i cant upload calibration same error everytime the wen pin..the worst thing is i cant warm up my car because is in recovery mode..help pls
Re: cant upload cal to ecu
What is the FlashPro serial number? If possible take your ECU and install into another vehicle. That often works to get it out of recovery mode if the vehicle wiring gives a low WEN voltage.

Re: cant upload cal to ecu
I also occasionally the same error in my Euro Accord CL9 with TSX ECU and FP. Solutions up to now that worked for me (all together or just one in some cases):
1. Make sure the ECU ground is VERY good (originally on the intake manifold, I moved it on the valve cover).
2. CTek charger in power supply mode
3. Drive 5-10 minutes
