i got an h22a bb4 p13 ecu here sitting on my desk..

i have no idea what its for or worth..

it has markings on it that say "h22A BB4" and the bar code on the side on a label with the numbers:

37820-P13-900
551-104545

as well as the code "4W" which is printed sideways..

i searched found that people put this ecu into accords and preludes but i would like to know what its best for

would it be good for an h23 w/h22a vtec head on a 4th gen.. ? whats the "4W" mean.. and how do i know if this is jdm/usdm and if its for auto or manual ?

please let me know! thanks

 

if its manual or auto it will say either 5mt or 4at on it somewhere....sometimes they say J-5MT or something like that...the jdm one has the j of course

you can look up the part number in the future for stuff like this....slhonda didnt find the part number, so its probably jdm....the us p13 part # is 37820-P13-A11

 

that is weird....i recently bought a P13 ECU off this site from someone.....they said it was a jdm p13.....on mine it doenst have a "J".....but the number is 37820-P13-A10. Do you think that A-11 could be US and A10 be Jdm?....i just wanna make sure the one I have is actually the JDM p13...

pretty sure the one you liated is a usdm model. i think thats the same number i have in my 94 vtec..

 

i think the 4w means 4ws and 2w is for 2ws

 

I just went to Majestic Honda and typed in the Part #.....and they didnt have a part listed for A-11 but A-10 did come up as the ECU.....so I am guessing i Do have the jdm p13......and yes 4w is for 4ws and 2w is 2ws

 

guys i dont think there is any correlation in the 2 and the 4....

i personally cant say for sure, but my local engine importer has evidence otherwise, in cross refernencing their computers and the cars they came out of, some 4s came out of 2ws cars....

 

did the jdm vtec ludes come with 4ws? cause i know the usdm ones didnt..... I actually have a jdm and a usdm h22 ecu at home, il will look at them when i get home.

so the a11 is usdm and a10 is jdm then hmm

 

a10 and a11 are USDM

i have a bb4 without 4ws it has just the LSD transmission (SI VTEC LSD)

 

there was a 4ws option on jdm vtec ludes...i know that much....both 4th and 5th gen
