about to chip my jdm p30 ecu, got a couple questions! ***PICS***
I started reading up on PGMFI.ORG's site about chipping the jdm p30 ecu here
http://www.pgmfi.org/twiki/bin...DMP30
but for some odd reason the J1, C49, C50, C92 all have capacitors like it was there factory, and the "74HC373" SMD chip is there as well.
Would I just need to de-solder the 28-pin ROM and replace it with a socket and a 29C256 EPROM with a bin?
heres the pic of my jdm p30

awesome news Jim!
btw, would it be possible to make a switch so that I can switch to the stock program and the chipped rom??

Yes you can make a switch!
Dude, be very careful taking the stock chip out and dump the rom and post it on pgmfi.org, evidently they love the stock reprogramed dumps, I'm going to send relic1 a link to this thread now,

Re: (T-RO)
i got a p08 box before that also came prechipped with the gold sticker stock, i couldn't get it to work with crome. it would work for a minute, then i'd get a solid CEL. hope yours doesn't do the same thing

the P30-010 is all ready dumped and documented. all though PGMFI.org says that the ECU isn't ready for a chip. Yours obviously is.
Could you please send me a copy of the bin in the OEM chip, so I can compair it to the one on PGMFI just to make sure there isn't multiple version out there.
(you can also post it up on PGMFI.org yourself - take credit for the work that way)
If you knew what the ECU was off of it would be helpful also.

That one is very interesting. 244 code should be a P29, and the G8 code is not currently known according to the wiki.

There are a lot of oddball JDM ECUs like this. Especially the reprogrammed ones. And this adds yet another reason why a dump from the prom is important.
Personally I have a feeling that when a custom order came in, Honda techs simply grabbed what ever ECU they had on the line at the moment and manually populated it to fit the order, then dropped in an external chip to match.
versatile, cost effective and best of all, available to the masses later in life.
