ok chipped my ecu, went to start the car and the CEL popped on. checked the code but the light just flashes constantly !.!.!.!.!.!.!.!.! i stopped counting at 140 my connections are all good, the car runs but i dont want to drive it till i can figure out what the CEL is...help!

i tried a stock chipped and same thing

JDMlyfestyle

know any one with a virgin p28? cause that might be your problem. might have put a resistor in the wrong spot which could give you your problem

looking for one now...i chipped it just like this:

2 caps in c51 c52, 1 res. in r54, and jumper on j1...that right? thanks

i have heard that if u chipped it at the wrong position, it will cause the cel light to be and it wont function correctly.

yeah, it seems to idle fine i just want to make sure before i drive it...damn CEL anyone have this problem????

one of my p28s has a resistor in R52 (virgin) and the other one doesnt(chipped one), whats the difference? thanks

Ya something has went wrong with the soldering. Or else its a bad chip those are the only 2 explanations i could give you

appreciate the reply...thats the only thing i can come up with also/ do you know why one of my p28s has a resistor in r52 and the other one doesnt (both virgins)? is there a difference/does it matter? thanks

JDMlyfestyle

the one with the R52 resistor i believe is a automatic. im not 100 sure but i believe it is.

its labeled P28-A00, according to this thread https://honda-tech.com/zerothread?id=681081 its a manual ecu/ but why the extra res.? losing my mind here i guess ill just take everything off the other p28 that i chipped and try it again :sigh: this sux...should i just chip the one with the xtra res. in it? thanks

JDMlyfestyle

hopefully this will help you. i see this one is a Manual p28 and it has a R52 resistor. maybe the one without the resistor is a Auto ECU.

1CiViC1

thanks for the pic, thats actually the one i followed. but i dont see a resi. in R52 in that pic. am i not seeing it or is it not there?

JDMlyfestyle

look right in between the red circle and the purple/yellow box the R52 resistor is right there.

1CiViC1

strange, the only res i see in that area is the one in R49, the one below it, R52, seems empty to me... here look at this pic:
see the R52 spot empty and the res above it is in R49? isnt it the same as the other pic?

JDMlyfestyle

ya ur right i was thinkin the whole spot right there was R52. so ya both have them in the R49 slot.

1CiViC1

ok cool. you think the year has anything to do with it? the one with the res in R52 is from a 92SI, the one without the res in R52 is from a 94EX. any ideas?

JDMlyfestyle

the year shouldnt have any thing to do with it. since they were for the exact same motor and no changes were made through that time span. my only explanation is its been tampered with or its a automatic ecu.

Since where on the subject of chipping and everything. To chip a ecu do you need a special soldering and desoldering gun or could you use a everyday normal one like the one you could get from Radio Shake?

check the solder traces on the under side of the ZIF socket.

going to do this tonight...only thing left to check...gotta be it :crossingfingers:

showtymers619

i got a problem like this also...if the cel blinks its a bad burn, but if its solid its a bad connection on a solder i suggest you desolder the zif socket and redo it
