d15b? ecu

Does anyone know if the d15b1 and d15b2 ecu's are interchangaable?
My 91 civic's b1 is about to croak (consumes 1qt of oil for every 200 miles - valve guide seals are shot, and the rings are beggining to give), and Im wondering if I can buy a b2 for a replacement and minimize the effort and time needed. Im not going for performance, but for a reliable car...

Thanks

i dont think it is i beleive the b1 was 8 vavle and the b2 is 16 vavles but dont quote me on this one.

Why dont you just get the d15b2 ecu, there about a bigillion of them in junkyards. If you need one i can get you one 10 bucks + shipping!

But otherwise the b1 ecu will work but not sure if it will work properly!
