Topic: Which ECU do I have?? (Read 16099 times)

funtimes · « **on:** October 28, 2009, 10:01:48 AM »

So I bought this ecu for my car and while looking at pictures I can't tell if it in fact is a P28 ECU. I am not near the ECU right now (this weekend I will be) but by looking at these pictures can you tell me if it is a P28.
What makes me think it isn't the P28 is that there is no R54 pin out under J1.
Here is some pictures.

Thanks for your help

Why don't you look at the sticker on the side of the ECU with the model?

92CXyD · « **Reply #2 on:** October 28, 2009, 10:06:51 AM »

What does the sticker say on the side of the casing?

What is the board ID #?

funtimes · « **Reply #3 on:** October 28, 2009, 10:10:36 AM »

The sticker is peeled off for some reason. And the ECU is NOT in my possession right now. I was thinking that if there isn't the R54 pin that means it is some different ECU.

yeah, hopefully for a P72?

I don't know what it is, but it's not a PR4.

Looks like a 02D01980-1500 board or a P75/P72?

you need a pic of the top of the board on the right side where the silkscreen labels the board instead of the bottom of the board right side where it was chipped. Stickers can be removed or swapped, look at the label on the board itself.

Do you remember if it had a daughter board? The P72's have a knock board i believe

Edit: I'd guess you have a non-vtec 02D01980-1500 like a p75 or something do to R115/R116 being unpopulated.

Thanks for your reply
Ill see if I could get my buddy to snap a pic of it for me. If it is in fact the non vtec ecu it will be worthless to me correct? I have a 1995 civic d series built motor.

d series means nothing some have vtec some don't

get a pic of the whole ecu so you can see if vtec is populated

I have a feeling it will be useless to you either way

Looks like a P75. Someone pulled the sticker because its modified. Get a pic of the other side to see if the VTEC components are installed.

Agreed, but does everybody forget about the sticker on the ECM connectors as well?

P75 ecus are the only ones i know of that dont have R54. Also P72 ecu will have the knock board witch this one doesnt. Did you also notice J1 isnt jumped so you will not be running whats burnt on that chip (if the chip is burnt at all). also C51 and 52 are not there. wonder if J12 is even cut???

Joseph Davis · « **Reply #12 on:** October 28, 2009, 01:23:07 PM »

Correct.

I will get pictures tonight of everything. I was told by someone that in the bottom left of that picture it shows the 4 pin connector and they said that is for the hondata to be plugged to. does this seem right?
Thanks

92CXyD · « **Reply #14 on:** October 28, 2009, 03:11:38 PM »

I do not know about Hondata but that is for data-logging.

Joseph Davis · « **Reply #15 on:** October 28, 2009, 04:23:53 PM »

We don't speak Hondata on this forum, sorry.

chris · « **Reply #16 on:** October 28, 2009, 04:56:07 PM »

c51/52 are not needed they are optional I have never used them and have chipped 100+ ecu's with no problems

Teg2boo · « **Reply #17 on:** October 28, 2009, 05:00:08 PM »

Litterature says it's better to put them

BangBusMaster · « **Reply #18 on:** October 28, 2009, 05:30:24 PM »

A 274 is a US P75

funtimes · « **Reply #19 on:** October 28, 2009, 05:37:08 PM »

shitty. Thanks for all the replies. So is this ECU not usable for me? (Sorry im new and trying to learn this shit).
I will do some reading about this ECU but is there anyone that can link me to a way i can make this work for my car or explain it?
Thanks

pgmfi.org is all you need. ;D

BTW where is your credentials I have not seen any pr0n or intro thread from you.

BangBusMaster · « **Reply #21 on:** October 28, 2009, 05:48:53 PM »

It just needs a few more things to be a P28. Need more pictures. That ECU can work for you.

chris · « **Reply #22 on:** October 28, 2009, 06:12:49 PM »

yup whoever did it left out j1 one too so it will currently run stock

There are numerous people here who can add the vtec conversion/j1 etc to make it work just like a p28

funtimes · « **Reply #23 on:** October 29, 2009, 11:52:56 AM »

Here is the model # in the top right

Ok here is the pictures of my ECU. So it looks like all I have to do is solder in my two capacitors to c51 and c52. Then jump J1.
I also bought C3 AMD AM29F040B chip so I could get a tune burned for me.
From my research I think i should be all set correct?
Thanks again for everyones help.

when I get back home ill post some up for you hahaha

Joseph Davis · « **Reply #24 on:** October 29, 2009, 01:05:36 PM »

J10. R67 missing, most likely other pieces. VTEC will not work.

FreshDA9 · « **Reply #25 on:** October 29, 2009, 01:08:17 PM »

Looks like you need to remove
J12
R136
R138

R136 & 8 being removed will help the wideband signal in data logging.

Add
A jumper to J1
C51 & C52

It also looks like Vtec hasnt been added so if you need to run this on a vtec motor buy a vtec kit for 1980 board.

funtimes · « **Reply #26 on:** October 29, 2009, 02:10:30 PM »

wow so i need that much more crap? Is it just easier to get a p28?

92CXyD · « **Reply #27 on:** October 29, 2009, 02:40:35 PM »

If you can get a p28 for <$30 yeah

If not just fix what you have.
