How do I tell what revision my ECU is and what precautions do I take to prevent a fried board?

 

Open up your ecu and on the hondata board, it should say rev. X (X being the number) printed on the board.

 

I just bought a relay that has a diode built into the unit and installed it, works great so far. My wideband is running constant power and ignition power from the open spades on the fuse box under the dash, I assume these are connected to a fuse?

 

So what's the current status of being able to run this setup, assuming brand a new PRB ECU and K-Pro??? I have a customer that's switching from AEM to Hondata and is interested in this but I don't want to cook a $400 ECU. Hondata changed the adapter board pin locations? Thanks for the update.

 

I have the brand new one I just got 3 weeks ago. I verified all the pin location still the same. I'm going to attempt the project.

 

Please more info on re wiring the stock o2 harness...
Oh n btw, I have some not nice things to say about Hondata. This is me not saying them.

Totally Off subject question : why do ap1 calibrations have cam angle maps?

 

B/c it is an rsx ecu.

 

I did it! It worked great. I triple checked the wiring. Just some info the 02 sensor is

1 - 2
3 - 4

looking from wire side on female connector or looking from terminal side on male connector.

Just FYI, I have the newest Kpro as I just got it a month ago. I didn't check which revision I have. I just verified the pin out with my kpro on the race car. Didn't seem they changed the D connector pin out. Everything is as described on Justin C diagram.

I have a feeling ShadowPh0x situation is wiring issue. Like JustinC mentioned, Hondata made a mistake before. It's also possible ShadowPh0x made a mistake in wiring it up. After all we are all human.

 

Who can tell me how to convert my existing tuned map to a PRB map? The tuner made me a PRA map despite my specific request to have a PRB map, even though I explained why I wanted the PRB. I want to be sure I know what I am doing in terms of copying everything over so I do not miss anything!

 

You can copy the whole map over cell by cell

and then go have it retuned, or then datalog and change fueling
