Like I said, Will an Auto ECU work with a manual tranny?? Im asking because If I decide to swap, or sell it, Its an Auto tranny an most likly will be swaping towards an manual tranny.. SO Will I need a Manual Ecu?? Im kinda lost, an im asking is because I seemed to have found a good deal on one..

Oh and my buddie said he wasnt sure, but said that for mazdas ( the cars he works on) the only dif he knows of is the auto one has a brain for the auto tranny an thats it.. but i have no clue.

yes, you need a manual ecu for a manual car.

i dont think so

the ecu will just send out signals for nothing

so long as u wire up the speed wire properly, you shouldnt have a problem

I am not an expert but have been advised that you can use the auto ECU if you do a manual tranny swap. You can't go the other way though.

i know your trying to do the right thing for your motor, but this is one of those times where you should just trust the guys who have had their swaps for a while and have done a ton of research into this.

You can use the AUTO ecu but it may leave you with a constant CEL...

that's a bad thing.

i believe the write up on toyotacelicaonline.com mentions a way you can do it without triggering a light.

good thread, i've always wondered if this would work or not.

My car has been swapped to a 5-speed. It still uses a auto ecu. There has been a CEL (From a bad O2 sensor tho). The only thing the auto causes is the OD light to flash after 60ish miles or so.
