WILL my dx ecu work on a b20 motor

 

[horny_devil]

u can make almost any honda ECU work on another. as long as u can sort out the ODB problems and the dizy issuse

more info on the b20, its a OBD? and its vtec or nonvtec?

 

[Green 91]

B20 is from a CRV it somes OBD2, but use a 90-91 LSdissy to make it OBD0,92-95 LSdissy to make it OBD1.

unless the ECU is chipped, it wont run very well

 

[TREBLE]

yes it will

Your fuel maps will not match very well so the performance will likely suck bad. read: very lean or rich

there is also a b20 in the older prelude, did ya'll know that?

 

[Toddnos]

yesh as long as its pgmfi not dpfi

 

[BoogiepopJDM]

you mean mpfi

I don't know if the dizzy off of those motors will work. I know they don't drop in like the rest of the b series

yea, i don't think they share very many things w/ the b16's and b18's...

IIRC; they are non-vtec...

yeah, but it sahres NOTHING with other B series, so some dont consider it a B series, theres a B21 also.

 

[mengy007]

The old b20s in the preludes are different from the newer B20b and b20z in the crvs. The latter of which are the ones that you want to be looking at.

 

[quick silver]

b20's are non-V-tech, it would be better to get a P28 and have it chipped to match the B20. alot less problems then anything.

 

[vtecduck]

b20's are non-V-tech

unless someone made it into a b20/vtec . Honda has VTEC, V-tech's are cordless phones :slap:

It wont run right all B series engines run a knock sensor something D series engines do not.

wrong not all B series run knock, one of the B20s from the CRV does not have a knock sensor. i dont belive B18a1s have themn either

 

[Belette]

I run stock B18B obd1 P75 Ecu on my moded y7, and no major issues at all. No check engine light, and I don't think it run knock sensor, Y7 doesn't have one anyway.

 

[hybridx]

you shouldn't need the knock sensor if you're nonVTEC .. I saw an article, saying that the dx ecu was fine, even though the b uses larger injectors .. honestly, I don't see how, with the cc differences in them. I'd use a b ecu.

B series use 240cc injectors the same as many D. Only 96-00 D16y7 use 190cc, you need to swap injectors.

well ill tell u from my expiereince i got a b20b jdm for my first swap i used the 99 b16 tranny and ls ingectors withe p75 piggyback june chip my idel was at 850 ran great love the torque but i would recomend the gsr tranny cuz myb20 went threw the b16 quick also treat it like a ls dont go reveing past 7500 or you will have valve problams and your valves start to float other than that its a great swap even after u swap the vtec head!
