Auto to 5 speed swap wiring questions!

[Caution]

when doing this swap, #1 advice is to pull the motor out to doit, it makes your life easier! Trust me!

[Davids92Accord]

yea it might be easier to do the swap while the motor is out but i dont have all the tools to do that

[Caution]

u got an engine hoist?

[Davids92Accord]

u got an engine hoist?

naw i dont thats why i cant do it that way

[Smokinspeeds]

dude, just rent an engine hoist. You will need one to do the swap.

For the other Q about the second *box* the ecu doesn't matter auto or standard, the second computer is the TCU controller and won't be on standard cars in the first place. Btw remove the tcu when you do a 5sp swap. Hopin to do mine soon as well.

Why would you want to mess with removing the engine? It wasnt that hard with the engine in place imo.

[defjamon22z]

wow.. remove the engine. rent a hoist.. how much u got it for?

yea ill rent one when i do the h22 swap but for the tranny swap all i need is to floor jacks

hey so your saying we can still use the ecu we have and just take out the TCU next to it

[Caution]

Yes, you can use the automatic ecu. YOu will just makke sure you hook up the wires at the shifter assembly correctly to make the computer think your in neutral or park!

[Davids92Accord]

oh alright i thought that you had to get a MT ecu because if you use the auto ECU it will run like shit

[Caution]

I ran my auto ecu on my 90lude when I did auto to manual swap, no cel ran ok, but let me double check this one in the repair manual! ill get back to ya

[Caution]

if it dont work and you get a code, it might be a flash 30 and 31, wich i believe are the 2 shift solenoids onthe transmission. But i also believe, if you got the computer wire in for the park or neutral mode, then that should not go about throwing the cel, Ok, but if it does, then you dont have the car in park or neutral!

There is no such thing as an auto ecu or a standard ecu. The ecu's only differ when there is a different car/engine model in play. That is why there is a separate tcu. The tcu has nothing to do with fuel maps, only when your transmission decides to shift. Hence with you shifting a standard you don't need a computer to decide when to shift. make sense now? Any if you guys are looking for performance, look into a chipped ecu setup. MRX is another member on this board and if you look in the regular section on technichal performance he has stickies on chipping, and he also sells chipped ecus. Which should also work with manual or auto (I'm auto and I have one I can run that was used in a manual before I got it.)

[Davids92Accord]

well the only reason i thought that we needed another ecu was because its on the 5 speed swap list and i was just following the instructions so i guess i was wrong but theanks for pointing that out man

AT and MT ECUs did in fact differ, not sure of the effects of the differences but one i know is that the AT ecu will keep the radiator fans running up to 15 minutes after the car is off, an MT wont. converting an AT ECU to MT is as easy as pulling out a couple transistors, but for details youll have to look it up. either ECU will work with either tranny, but of course for an AT youll need the TCU as well.
