Hi
I have stock B18C4 with P9K ecu in my Honda civic EJ6 96. Problem is when I swap motor I must bypass immo. I bought DocTronic IMMO bypass and solder it in ECU. When motor was completely in my car ECU not give spark but fuel pump starts. With some other ECU from my mechanic motor works. I think that problem is with immo. I tryed desolder DocTronic immo, solder my stock immo from D16 ECU and soler it to B18 ECU. Not worked. I tryed join J20 and RP23 (from underside ECU) and desolder RP24 rezistor. Not work. ECU still not giving spark. Have you ever had same problem ?
Thanks

 

You may have damaged your ECU during the soldering/resoldering.

 

Today I resoldered DocTronic immo bypass and test it. When I plugged key with immo to the ignition, immo light on dash didn´t blink. When I plugged blank key, immo light start blinking. So DocTronic bypass is working. I don´t think that I damaged ECU because I soldered only in immo area and immo is working.
But I still have problem with that spark.
Btw my distributor working but it not showing rpms on tachometer (tachometer is good). It can´t cause that problem ? With my mechanic ECU motor starts but he has plugged in P28 programable ECU and I have stock P9K ECU with bypass immo.

 

^Rules out distributor problem. Your ECU may be toast.

 

Thanks for help. My car is working. 2 weeks ago I bought P28 ECU and everyting is fine.
