So i have a d16a6 still 5 speed transmission. I got a p28 d16 ecu. Now before you try to tell me it isnt a manual ecu it is. I opened it up and checked i can not convert it cause rp17 is empty nothing there. So i chipped the ecu have a chrome tune on it and i have a code 19 A/T lock-up control solenoid. Now if you can tell me how to fix it i would really appreciate it. I did try resetting the ecu re burning the chip. It runs ok its just that this code is not going away and im not sure how i can fix it. It is also a p28 A02 so i double tripled check please understand. It is not an auto!!. I am very confused and frustrated if anyone can help please let me know. i also bought the harness obd0 to obd1 off of ebay the one that is already wired up right and i connected my air/fuel to my 02. So any more questions let me know and please give me any suggestions ill take any any at all!!!? Thank you. Also almost forgot it is a 1991 honda civic si was originally p06.

 

What happens when you put the p06 back in?

 

well i cant cause i put 550cc injectors and new fuel pump so the car has way to fuel getting pushed into it. So i cant put it back in

 

As if your saying anyone with a stock 1.6 with p28 or 06 randomly goes and throws in nothing but 550’s it won’t work?

Is that true?

sames goes for the fp

 

It's turboed that's why?

have u seen this

 

You sure you are getting a 19 and not a 10 and a 9?

 

yes I am 100 percent sure trust me I have had other Honda guys look at my codes owning the same year and they all said it was a code 19. But arnt sure how to fix it.

 

Find the pin out for your ecu and find out which are relevant to the code 19

check out your conversion harness see if those wires are not present on the conversion harness maybe that’s it

 

Sound like the tune loaded might be a tune for an auto an expecting to see circuitry for auto.

 

ok well I used chrome how did I do an auto the or how do I change it to a manual tune?

 

t even tho it runs like **** with the chip out cause of the new injectors, and the cod didn't come up? Why is the chip causing this code? is there a reason for that?

 

To be honest, I have never used Chrome.
Just looking at the the error though - if you 100% have a manual ECU hardware then I'm making an assumption that software is saying it's auto.

 

how to change it does anyone know?
