I just converted my 97 Geo Metro 1.3L to a standard transmission.
The part that is giving me headacks is the PCM.
1.3-AUTO-FED: The auto PCM with the 5 speed installed gets error codes for no speed sensor, no shift solenoids, and no neutral safty switch.
1.3-MT-CAL: The PCM I stripped from the junkyard was a california 5 speed car, and I get error codes for the fuel evaporative recovery system. Speed sensor is accurate.
1.3-MT-FED: So I broke down and got what I though was the right PCM from a dealer in Penn. on EBay. I am not getting any codes on this PCM but the speed sensor is reading about 62% to high with a diagnostic computer hooked up to the car.
What I need is for someone with a 97 1.3 5 speed federal car to pull down the glove box door and
get the right part number for me please.

I assume you mean the ECM or ECU--the computer?

This Russian page has pretty much every part number for all our cars--the American model (e3) is listed under Canada for some reason but the part I get for the fuel injection controller for a 4 cylinder MT car (number 34 on the diagram) is

33 920-52GN0

Check it out--it's freaking amazing.

Once you get the cars dialed-in (compression, leaks, bearings, alignment, brakes) swap in new rubber and glass, you've got something which should last for years!

Thanks for the lesson in terminology :D

Ebay listing below confirms 3392052GN0 is correct part no., read tag on PCM...

That is the unit I brought on Ebay.
It kinda works. The speed sensor reads 64% high.
I guess I need to get it reprogrammed.
So who do I send this PCM to? To get it reprogrammed?

the ecu gets its speed reading from the output of the speedometer. with everything youve done to the car i wouldnt be surprised if its the cluster thats not right now.


edit: my mistake. according to the wiring diagrams i have access to it comes from the VSS on the trans. i dont remember seeing an electrical VSS so ill have to double check this.

The cluster works fine with the california PCM 1.3-MT-CAL
But the other PCM 1.3-MT-FED reads about 64% higher then it should.
What I need is someone who can tune or reprogram the Fed PCM. The speed sensor, fuel enrichment, and the timing curve are off. The Fed PCM has only 25 degrees total timing, Long term fuel trim is about 5% to rich, and
again the speed sensor is reading to high. This until may have sat on a shelf to long, has lost it's memory, and is now running on defaults.
I have actually pulled the Fed PCM and have the Cal PCM installed. Mileage is better, speed sensor is right on the money, and the total timing is up to 40 degrees. But with the CAL PCM it is still throwing a code (P0450).
Evaporative Emissions Gas tank pressure improper. The CEL light is on.
To be sure it is not another problem I will be doing all the tests associated with this code.
There are only 2 electrical items to this system. A vacuum solenoid and the gas tank pressure sending unit.

try changing the purge valve, it connects the hose from the evap cansiter

Automatic VSS is in the transmission and is a 2 wire setup to PCM C3-2,14.
5 speed VSS is on the back of the speedometer, is a 1 wire setup to PCM C3-11.
There is also a connector under the dash to the main wiring harness near the glovebox number 205.
205 is mostly for the dash warning lights, but it also has the speedo VSS wire bundled too.

I tested all the electrical for the evaporative emissions system. Tomorrow I will check the vacuum valves for operation.
I replaced all the engine vacuum lines about 7 years ago. It may be time to replace them again.
