i thought these had like disc capasitors or somthing.. this is a P72 obd 1 GSR ecu..

 

up cause im pissed

 

 

maybe thats why that mother bitch blew up... damnit ill have to talk to this dude.. see if i can get few dollars back

 

i dont have R54 on my p72 though.. whats that about?

 

The pic os of a P28, but I'm pretty sure you should have those capacitors/resistors that are circled.

 

i was thinking the same thing. wish the dude would have told me that.. he said plug it up and haul ***.... he neglected to say u will fry this mother bitch in 2 hrs.

 

dang, that's weak

 

I was looking at your other post about the resistor. I would replace it with the same value. Looks like thats the problem.

As for the caps, I haven't run them but I do run a P75. I DO NOT have a R54, yeah I was confused too. On the Hondata website they say they only used the caps on one occasion when emulation would not work right.

Remove J12, change that resistor and see how that goes. You can do it!!!

And that resistor that you have thats burnt, mine is gold gold green green also.

its gold gold blue green... look really close.. anyway that only fixed my check engine light.. didnt fix the power problem.. thanks though i ordered another fukinc p72.. another big chung of change out for the honda.... anyone want a 250 whp h23 lude at 7psi?

 

I have a P75 and I have all the stuff on there...2 caps, 1 resistor and the 20 pin DIP.

And of course you know I sell this stuff if you need a "chipping kit" or any of that good stuff.

 

Neither P72 nor P75 have an R54. It's a quirk of their motherboard.

 

According to the Hondata site though, he needs the C51 and C52 capacitors.

But this could be another isolated case. I doesn't hurt to try.

 

u think this is why im not getting power? should i go to radio shack and get some and try it?

 

Im have a question about the Hondata setup with OBD1 ECUs. Does the ECU have to be chipped? Why? And who can do it?

 

You do not need the capacitors, and it will not cause your ecu to fry. usually Fried ECU's are from shorted our wires. Look at the bottom of our ECU and see if there is anything burned up there. You may also just have bad wiring in the car.

 

agreed, these are just filter bypass caps for the power supply to the chips. you need not install them. i personally put them in anyway because they can't hurt. guaranteed, that is not the source of your problem.

 

yea i tried lookin at my ecu for the past 2 days. i found 1 resistor that was fried.. replaced it and that only fixed my CEL problem.. ordered anoher computer

 

ahh decoupling capacitors. welcome to my world.

 

to the top. need to watch this thread...
