very VERY specific p05 ecu ?

[high c]

hey guys, like the title says i have a p05 ecu and i have a question about it...i have just chipped it to accept uber and also to be able to datalog with it by adding a serial port. My situation is when i plugged in the computer to try it for the first time, i think i smoked a couple of the resistors on the board. (A piece came lose that i didnt notice before i plugged it in.) I have since fixed the problem of the piece that came loose, but now i am just trying to tie up some loose ends, just basically trying to make sure they are ok. I have been to radioshack and stuff like that, trying to find the ohm level and tolerance of the resistors i fried...and they couldnt really give me a difinitive answer because i dont know if the colors are true bc of the heat and shit...

so my question is this, i need to find out what resistance and tolerance the resistors are on the p05 (92-95 civic 5 speed i believe), in pins R58 and R59. They are the same resistor, i just need to know what they are suppose to be in order to check/replace.

Please someone help me out here...any kinda advice is much appreciated!

pm midniteracerx, or accordr33....they should be able to help you.

I believe it is a resistor used for IACV operation and should be a 10K...but I'm not sure of the tolerance tho....can you make out the 4th color clearly?

[high c]

well the four colors i can actually make out are brown, black, brown, black...which makes no sence to me at all, because neither brown nor black are the tolerance colors lol.

So when i got home i was kinda wondering if my stock (91) accord computer had these resistors in them, so i open the bitch up and found a pair that are grouped together just like in the p05 ecu, and appear to be the same color bands. So assuming they are both the same resistor (which i am 95% confident in bc of color banding) i decided to test the resistance and maybe figure which were bad and then just swap them out from the stock ecu and put them into the p05.

here is what i came up with

PT3 ECU~ stock accord 91
~resistance tested @2000k~
-both tested '000' regardless of polarity (which side i put black probe to or red side)
-location is pin 'R4" and pin 'R5'

P05 ECU~ 92-95 civic 5 spd
~resistance tested @2000k~
-'294' both w/black (-) probe on connector side*
-'475' both w/red (+) probe on connector side*
-location is pins 'R58' and 'R59

*-"connector side" is the side of the ecu where the complete wiring harness plugs into ecu

So my question to you guys, is from this information, assuming they are the same resistor, one set has to be bad...is there anyway a couple of u could go out to either your PT3 ecu's, or your P05 ecu's and test the resistance of the resistors in the locations specified and post them for me, or pm me, or hit me on aim? It would be very much appreciated and i would be more then happy to owe anyone that helps me out a favor in the future...PLEASE PLEASE PLEASE PLEASE PLEASE help me out!!

I have my ECU taken apart and at my house. I will take a high-res. pic for you and post it up here later today. I'll PM you with the details as well.

I have one or two scrap ecu's i'll see if they have the part your looking for.

This may or may not help

couldn't find r58 or r59 tho

[bracersi]

Here you go buddy. With the color code on the resistor you should be able to figure it out.

Brown
Black
Gold
Red

They're both the same. I don't have a multimeter in front of me or I'd probe em for ya. It looks like a 1ohm if I'm reading the bands right but that doesn't seem right. Anyone more efficient at reading resistors?

[Gen4Acclude]

1ohm 20% tolerence my dad work for weyerhauser as a radio technician and this is all he does for a living for the last 35+years so i know it right hope it helps

[T3h HoT!!]

thats kewl, ima be studying electronics soon. hope it's easy... theres alot of shit u gotta study, but im alright at it so we'll see how it goes...
