E36 M42 Swap to E30 Sedan - Issues

[janithdg]

Hi All,
im a bit new to this,
i recently did an m42 swap to e30(316i m40),
engine was sourced from and 92 e36,
i was been able to make and adapter harness, from C101 to X20 to make things neat,
and today i found out the ECU is going really hot, to a level with i cant even touch it, any idea's where to look for?
and i also have an issue where if i apply the throttle in an gentle manner engine revs properly, if i rev it by hand, engine bogs and have intake back fires

any idea where to look out for
