I just chipped a p72 and I used an obd2b to obd1 harness adapter I had left over from my 99 civic si.

When I turn the key the fuel pump doesn't prime and it won't start.

I used uberdata and imported po6 maps.

Are some pins different on the CX? It works fine with the original ecu.

 

need more info on the p72. car, swap...ect.
p06 is a dx ecu.
did you chipped the ecu yourself? if yes, check all the solder joints.

Yes I chipped the ecu myself. I am going to cut J1 and see if it works like that.

The car is completly stock, so I figured the dx maps would be okay. But it doesn't even prime. The ecu worked in my 99 si but that was before I chipped it. I am going to double check the solder joints too.

 

okay, I cleaned up the solder and used rubbing alcohol on the board to get the flux off. I cut J1 and it now primes the pump and starts but dies - I assume that the stock gsr program is way to rich.

I reconnected J1 and it behaved as though it wasn't connected. I think it is because I could not get all of the solder out of one of the holes on J1 so I tried to surface mount the jumper.

I am going to get some more desoldering stuff friday and try again. And also burn a stock d16 bin. I hope that does it.

Any pointers on getting the solder out? I used desoldering wick and a suction pump, but it seems as though there is a air bubble in between so that the soldering iron only heats up one side. I guess I should try a smaller tip or something.

Thanks for any help.

 

when you cut the j1 jumper the ecu should run stock program. what ecu are you chipping p06? take your time on soldering. are you using any flux? flux would help out a lot on soldering. if you are do a lot of solder and desolder you might want to look at these.

I am chipping a p72.

Those look great, but a bit out of my range. I am using radio shack cheapo ones.

The p72 doesn't use the resistor at R54 right? It is not labled on the board and I read a thread on http://www.pgmfi.org that the p72 doesn't use it.
