problem with kpro ecu not recognizing ingnition being on

[mprat1985]

first off my kpro board serial number is 05005156. its installed in a pnd ecu. it doesn't look counterfiet.

this ecu was working fine for me in my all motor ek hatch. well i took the car apart about a month ago and the ecu has been sitting ever since inside my house.

i have another prb kpro that i use in my rsx that works perfectly fine.

i tried to hook up the pnd kpro to my rsx and download the calibration from it. When i plug the usb cable into my laptop the d1 led on the kpro board flashes red and will not recognize the ingition being on. i also went and tried it in the hatch and same problem.

does anyone know what might be wrong with it? thanks~ Matt

Have you tried swapping the K-Pro baord from one ECU to the other?

no i haven't do you just unscrew the 2 screws and pop it out?

[Spunkster]

yes

[mprat1985]

ok i took the chip out of the pnd ecu and it worked fine in the prb ecu.
i took the chip out of the prb ecu and put it into the pnd ecu. now d2 lights up green and d1 flashes red but won't recognize the ignition being on.

What is the serial number of the ECU it was installed into originally?

[mprat1985]

37820-pnd-a06

[Spunkster]

that is a part number, the serial number is below that.

[mprat1985]

oops, 2062-603330 0D22

It sounds like the K-Pro is workign correctly, but it is the ECU that is damaged. THis is caused must likely by improper or faulty wiring. You need to resolve this before attempting to replace the ECU.

i just tried it again in my hatch and it connects and is able to upload and download calibrations. i wonder what caused that to happen. the only wiring in the hatch is a hybrid racing swap harness and its grounded properly. i don't see how that would be the problem. my rsx wiring is fine too.

Same problem:
civic ep3 (eudm)
ecu 37820-PRA-E12 318853-4719
Hondata K-pro-III 12799

in the first time the ecu work but after the datalogging is impossible, the ecu is impossible to change all, is impossible upload any calibration, the ecu is in error, at 4000rpm the engine stopped... in this time i have only remapped the ecu... the wires is STOCK, the engine modification is:
itb, cammes skunk2, all the head, all the exhaust and the aem wideband(don't interface to ecu)...

my cliente is very angry, have you any idea?

Who installed the K-Pro into the ECU?

[voodooo]

I don't know who is installed, but i have check(i'm a member of team pupazzor, in italy i have buy, install and tuning more s300 and more kpro in honda ecu, i buy to alientech italy) and is ok, the ecu when is arrive inside the car is perfect, when i must tuning to road about 2 hours later have the problem, but the ecu have work for 6 month! For you is a ecu problem or k-pro problem??

Remove the ECU form teh Case and post pictures that are high resolution and in focus of the top and bottom of the ECU with the K-Pro board pulled out.
