I just ordered 3 P06 ecu's from a member on this site but when they arrived i got 2 P05's and 1 P06. What are the differences between them and also how can i tell the difference between auto and manual.

 

If you are going to chip them, it doesn't matter. If you are going to use the P05 as a stock ecu in a DX/LX then it does. Pgmfi lists the P05 as using a 1 wire o2 sensor. I'm not sure about that, my d15b8 swap had a 4 wire o2. Anyone confirm this?

 

The only difference between a P05 and P06, is the O2 heater transistor.

 

and the stock map/ mcu.
So I just did some reading at pgmfi and some p05 ecus had 1 wire 02 and some had 4 wire o2.
Check if you have Q30 and if not, add the q30 transistor in then your ecu is ready to use the heated o2 sensor.

 

Damn. I order 3 Manual P06's and i get two manual P05's and one auto P06. They dont have Q30 but i guess its an easy fix. Can i just buy a transistor and radio shack?

 

It's a C144 transistor that you need.

The auto to manual conversion is really easy:

USDM Auto to Manual:
* remove RP17 and RP18
* replace RP18 with a jumper wire

 

What exactly are you planning on using these 3 ECUs for?

I have a hard time believing you would buy them and sell them but not really know what you are doing with them

The Q30 transistor is the same as the Q26 NPN transistor...

 

I dont really get what your saying. I bought them. Im not planning on selling them. And i do know what im doing with them...im chipping them. Now i just have to do a few extra things to them that i didnt expect but its not a big deal. What did you mean?
