[carmageddon]

hi


if anyone need to rework pcb the component are the same of FG v53.


here is the list and pics of mine




KT 200




U13-U14 : L9613 / E-L9637D


U20 : HEF4011BT


U2 : LPC 2119FBD64


Q11 : ZVP2106 (look for the mounting position because the china copy are wrong)


Q12 : ZVN2106 (look for the mounting position because the china copy are wrong)


U18-U22 : ST 485B - MAX485


U19-U21 : LM393


U3-U5 : LM1117


U17 : PCA82C250 for 0-12v obd (PCA82C251 for 0-24V obd)


U10-U12-U16 : 74HC14D


U15-U23 : 74HCT125D

Why rework? It works like a charm...

[carmageddon]

is a china clone…many errors and poor quality in each component…

[Thomas Smith]

Where did you buy it?

[carmageddon]

various seller of this tool have european site but this tool are made only in china…i buyed by ecuhelp

[SoftDev]

OK, but how does this affect the work of the KT200? Have you found any problems or just find that some elements can be replaced with others? We all want to drive Michelin tires, but most drive Chinese tires, and there's nothing wrong with that.

[Aladinnu]

what a cheap looking board....u can tell by looking at soldering...its hard to trust a clone like that on a expensive ECU. i wonder if foxflash is same quality...

[halofane]

what about firmware for mcu KT200

[carmageddon]

@ Aladinnu : fw is the same but foxflash have not encryption module then maybe can be read…kt200 and other same tools use encryption module…i tried to read with usb to uart but have no comm

[halofane]

if not a level crp3 you can read mcu

[carmageddon]

as i wrote, no communication with classic connection uart, maybe foxflash can be readed...kt200 have encryption module...i think not so simple

[halofane]

so you have to find a foxflash to read the firmware

[carmageddon]

yes, or maybe a good boy that work in yellow town and want to share it

@carmageddon (https://www.digital-kaos.co.uk/forums/member.php/150846-carmageddon) with this rework did your kt200 obd read/write improve? i can read/write ecu's that use k line with obd protocol, but not a single ecu that uses CAN with obd protocol.
On the bench no problem with k line or CAN, read and write perfect.
i dont know if it is an hardware problem or a software problem.

i have no problem with can via obd, i did many cars

I had a problem with this microcircuit, it got warm and BENCH did not work
