This is pretty much for anyone that is curious as to what ECU codes they will get after doing a 5spd conversion. This is from my personal experience. Almost all are related to the auto tranny. I think I read somewhere that getting a manual ecu will solve the ECU light coming on.

These are the codes I get (I would assume anyone else doing the conversion will get the same):

4-1 (Intake Air Temp Sensor, most likely just when I kept taking my intake in and out).

5-4 (Automatic Transmission Control Unit Signal to ECU)

11-1 (Inhibitor Switch) ?????I HAVE NO IDEA WHAT THIS IS??????

11-8 (Shift Solenoid Valve A (A/T))

12-1 (Shift Solenoid B (Automatic Transmission))

12-3 (Overrun clutch solenoid valve (Automatic Transmission))

12-4 (Torque Converter clutch solenoid valve (Automatic Transmission))

12-5 (Line Pressure Solenoid Valve (Automatic Transmission))

It took forever to get these damn codes out! (well maybe 10 mins)......

 

getting a 5 dp ECU makes sense, although I'm not sure if it works 100%

 

the code i got...

4-1
5-4
9-5
11-8
12-1
12-3
12-4
12-5

 

I hope the 5 speed ecu will fix the problem.
