If I am planning on taking my car to get tuned the only thing that I need to have is a chipped obd1 ecu correct?

 

more like a socketed obd1 ecu. see moates.net for their kit , i think this is what i used for my p28:

then download crome and use this to burn the programs to the chip:

that last part is optional if you are going to let your tuner do the chip burning.

this also assumes your car is already obd1, otherwise you might have to get like an obd2-->obd1 conversion harness. search rywire for that.

edit: an adjustable fuel pressure regulator and fuel pressure guage are helpful as well.

 

1. Make sure you have the proper sized injectors & fuel pump along with regulator etc.
2. Make sure your vehicle is not throwing any major codes such as tdc/iat etc...
3. Get your self an engine management system such as a chipped obd1 ecu on crome, hondata, ectune, neptune etc.
4. Contact your tuner for his requirement list.
