wrong. You need a different ecu. Check engine light will come on, and when your check engine comes on maps change. You can convert a auto to a manual very easily.
this. it also changes the characteristics of the car.
you have it backwards. They were not at all pointing you in the right direction whatsoever. Paden and Dlo are trying to help you, but you are only wanting to read what you want to read. Which, is the cheap way out which may harm you in the long run. I actually am quite perplexed as to why you are asking if you need a new ecu. You may have gotten a bad ecu, or it was an ecu to the wrong OBD. Im not sure of your problems, but when i had an obd1 ecu automatic on my manual i had idle problems as well. My car was not converted, i just wanted to run a single o2. This gave me idle issues. You should upgrade injectors, you probably should upgrade internals as well. As paden explained. I would try another manual ecu first.
You asked if you needed internals. you shuold buy a new ecu
i try to stay out of the DA forums and FI forums. lol.
have fun at TI or Honda Tech!
