Hondata

sn is 12395, software was 4.5.5.0, now it has new update, 4.5.6.0, i will do this update, but for now i can't check anything, because my engine blow up :(
i will try with stock engine when it's ready

i am using ngk laser iridium, it says it is resistor spark plug, and grams 550cc injectors, it was all fine, before last two updates...
after update, i had to reupload map, and that was ok, but when engine started, then the problems start

after last 2 updates i can't connect ecu with laptop, when car is running, when car is off, sometimes i can connect, but mostly no...
i am from europe, use eu model ecu, pra-e13, hondata kpro v3, usb drivers are ok, kmanager is online, but it won't connect, usb error...
before updates, it was ...

hi, i have similar problem, i can't connect my laptop when car is running

hi,
can i remove hondata kpro v3 from k20a2 ecu and instal to other ecu, also k20a2?

ok, thank you very much for the info and your time to help me

uf no good :(
can i reuse this kpro in other ecu?

what do you mean ''at this point''? i dont understand? hondata made this ecu junk now?

i was using it like this 1 year, maybe more, without key code, it was working fine, before i installed hondata in it... it still works fine, but this errore code and cel bothers me.

I figured that this might be a problem, to bad, i will drive it like this till i get new ecu...
if i install stock map in this ecu and then remove hondata from it, will it work like before? like a normal ecu?

i dont know what that is... i think it is replacement for that one little resistor that comes with hondata, but i did not get it, it was lost in package, so we put this bigger with same value.

key code chip, that reads from immobilizer, it was removed from ecu before i had hondata, i could not ...

can the problem be that the key code is removed from the ecu before hondata was installed?

is this ok? or do i need the photo other side?

i have erased ecu, and put the new calibration for PRA ecu, and this code is still there, i will try again, maybe it is ecu damaged, how can i know that? car runs great, everything works ok, except this error code is all the time here, and CEL is on...

i know, but i have tried all ecu calibrations and this error code keeps poping up :(
current calibration is for pra ecu, still not good, maybe the problem is that the battery is too far away? can that be the problem? to weak battery or wires?

hi, did not see you reply, sorry, i use z4 trans, and i have ktund vss converter, now it is fine, it works, thank you
