Rb20e To Rb20det

[aphid]

Hey guys,

In the not to distant future i'll be converting my rb20e to det by slapping on an rb20det head. The car is an a31 cefiro and automatic with a view to convert it to manual in the long term, but for the moment I'd like to keep it automatic.

The cefiro uses an older style ecu, however the pinouts with the newer style r32 ecu are much the same. I've already got a 32 ecu kicking around, which I'll be using in the conversion along with an r32 loom spliced accordingly.

The question is to run the auto ecu what would I be better doing, figuring out which wires the original ecu needs to control the automatic box and splicing them in appropriatly (I think the ecu needs to retard the engine ignition on gear shifts, so shifts would be rough if this option was taken) OR take the 32 manual ecu and flash the firmware from an automatic r32 on there? I'm not sure if the gearboxes are the same electronically so could somebody confirm if this would actually work or not?

Anyway, any input would be greatly appreciated,

Thanks for your time,

Mark
