Is there a difference in power using richies module to do a 6 speed swap with a auto j32a2 vs a complete 6 speed motor/tranny/ecu swap ? Are there any disadvantages using the module?

 

Doing the swap, you will gain back lost power...The manual gets the power to the wheels more efficiently than the auto trans does...
So in the end, doing the swap will get more power down, but it does not have anything to do with the harness itself.

And as far as I know, richies harness will do no harm...I believe its purpose is to trick the ecu into thinking that there is an automatic transmission, therefore everything works properly and does not throw any codes.

 

There is no power difference between doing the complete swap with ecu and harness vs the modules. The module just makes life much easier.

 

Ok thanks gonna start collecting parts here in a couple of weeks.
