Running MJ upside down and heat query

Post by Quicksilver »

Hi all,

I'm yet to test MJ (V4) in its intended home but I wondered whether either MJ or EDIS developed a significant amount of heat during normal operation? Following on from this, I was wondering if MJ would complain about being installed literally upside down within the standard MJ casing?

Any help much appreciated!

The MJLJ does not generate an appreciable mount of heat by itself. If installed, the hard rev limiter module will generate heat while rev-limiting is active.

There is no concern with regards to mounting orientation of the MJLJ. Out of curiosity, why do you want to mount the MJLJ board upside-down inside the case?

The EDIS module generates a modest amount of heat, but that heat is coupled to the body of the vehicle via the mounting bracket.

Thanks for the prompt reply, Brent.

I intend to use a stock ECU housing to house both the EDIS module and MJLJ unit. Due to the location of the MAP sensor nipple and a potentially suitable communications port location, MJLJ would sit ideally if "upside down" (keeping the original case incase of alternative applications in the future). I'd originally considered dismantling the EDIS module itself and mounting the PCB somewhere within the ECU, but the fragile nature (dismantled a spare EDIS module) of its PCB disuaded me somewhat! There should be a reasonable amount of room within the standard ECU housing but nil airflow..
