Turbocoupe drivetrain into 87 4 banger, wiring how hard?

one last question, you say I can use either ecu with a 5speed but for an auto I must have an auto ecu. why is this?

if I decide to convert my setup to stickshift (since it's automatic) will this cause it to run richer.

Also, I will probably down the road do what you suggested and convert to the 87-88 ecu and what not. however, for now, cost dictates to me that I must stay with the 86 setup (if it indeed is an 86 or earlier).
 
The A4LD is computer controlled...OD won't work without an auto computer.

Why would it run richer? I already said you can run either computer with a 5 speed.

You can pick up an 87-88 auto computer (LB3, 8AU, etc.) for like 30 bucks. Big vam is 35...ACT is free at a JY (or not use one for now). So for less than 70 bucks you could convert from 155hp to 195hp.

in your area of town they might be that cheap but I called around earlier and they certainly are a little more expensive here in atlanta.

anyway, the reason I wonder if it would run rich is how would the ecu react when there is no automatic transmission to control??
