Are the computers the same?

[turbocoupe]

Ok im swaping a 5spd in my car and want to know if the auto and manuel CPU are the same or are they differ:eyebrows:

[inmyshadow]

Well, I've swapped between auto/5spd computers on my both my 90Shadow/91Shadow. Everything worked fine.

I know local kid running his 87 Shadow 5spd with an auto computer. He says the car runs like crap at idle. But works good every where else.

[turbocoupe]

why is that tho what makes it run like crap at idel

[turbovanman²]

They will work, but the best combo is 5spd cal in an auto, the otherway, it will idle funny, badly or not at all. You could play with the throttle plate opening to help I guess. I have done 5spd to auto but never the otherway so not sure what it does.
Why, the idle cals are different between auto and 5spd for obvious reasons, :thumb:

The idle messes up from the torque converter load , or lack thereof depending which way you've swapped . Also a stick cal will hold idle speed 1300-1500 when the vehicle is moving .

ya that what my van does 1100 till i stop then drops to 850 but for the rest seems to work fine. AL

I have an SMEC from a turbo/auto Caravan in my Omni GLH, which is still manual. It idles really high on cold startup, especially if it's cold outside. When it's warm it idles a little too low. It idles low with the car coasting too.

so just to get everything to function properly ima just get a 5spd cpu.

[iTurbo]

Yes, but it really isn't THAT bad. If an auto computer is all you got, run it. Personally I don't think it's worth finding/buying one. I have a 5sp SMEC from my old Shadow I was going to put in my Omni in place of the turbo Caravan SMEC I have but I haven't bothered.

I don't care I'll just go to my local junk yard i know the people their
