Dude if you figured this out and made something or posted how to fix this you would be THE MAN!! I have to pay a emission testing employee 200 a year plus tags to get my tags renewed. Keep us posted with anything you find.
Well have been working on cleaning up a few things, and am looking at a temporary fix (short of an ECU swap) to get rid of the codes that pop from the manual transmission swap. Can someone with an I4 Swap, and others who have also done the swap, verify/confirm the codes that are popped?
Here are the relevant codes that pop for me:
P0743 Torque Converter Clutch Circuit Electrical
P0753 Shift Solenoid A Electrical
P0758 Shift Solenoid B Electrical
P0763 Shift Solenoid C Electrical
P0768 Shift Solenoid D Electrical
I'm guessing that the ECU is just looking for a certain voltage range for the different circuits, and if we can just provide a steady voltage to each, then the ECU would act as if all is well.
So far, from the service manual, the Torque Converter Clutch Circuit, and apparently all the Shift Solenoid Circuits should have a reading between 2.6ohms and 3.5ohms.
All the wires appear to be on connector B-38:
Pin 3, Red, Under-Drive Solenoid Valve
Pin 4, Red-Yellow, Second Solenoid Valve
Pin 5, Blue, Overdrive Solenoid Valve
Pin 6, Red-White, Low/Reverse Solenoid Valve
Pin 7, Yellow-Red, Torque Converter Clutch Control Solenoid Valve
Underdrive Solenoid: Resistance between pins 3-9 should be at 2.7 - 3.4 ohms
Second Solenoid: Resistance between pins 4-9 should be at 2.7 - 3.4 ohms
Overdrive Solenoid: Resistance between pins 5-9 should be at 2.7 - 3.4 ohms
Low-Reverse Solenoid: Resistance between pins 6-10 should be at 2.7 - 3.4 ohms
Torque Converter Clutch Control Solenoid: Resistance between pins 7-10 should be at 2.7 - 3.4 ohms
Pins 9 and 10 appear to go to a power source.

Someone who is swapped needs to just start trying things to replicate signals.

those were exactly the codes i got after the swap
Len resisters should work... thats how people were getting rid of the CEL's when doing the ecu swap before you could use ecuflash.
you could always just try one and see forsure

try a resistor with those ohms -- i find it easier to use a potentiometer and play with the resistor settings till the code disappears.. try wiring to ground with those ohms and see if it dissappears

Just go to radioshack and pick up some 3 ohm resistors and solder them on there. That should do it, right?
aint gonna work... i set way too many fires in my engine bay with that resistor crap.

any extra modifications needed to swap a 2000 ecu into a 2002-2003?

:( damn...
there's gotta be some way to get this project to work while still being able to flash the ecu and no CELs....

Don't start with me... when i see smoke in my engine bay i drop and roll then get up and put out the fire. j/k
But trust me on the fact that you don't really want to screw around with those wires.. They go straight to the ecu and a wrong resistor combo can possible burn something out. I was always able to eliminate 4 out 5 codes. Every time i put in the 5th resistor it smoked. So stop being cheap and ignorant and buy an evo ecu or a 2000 auto ecu. Come to think of it… I’m now pretty sure that you can run an auto ecu with the patch from flashbluers to convert it to evo. At least on the 02+. As for 01 and up you’d need to change the reluctor still. So if anyone really wants to try let me know.

could you possibly get a conversion harness of some sort ie boomslang or something? this way at least when it comes time for inspection you can just swap the ecu out a day early or something drive the required miles and get the test done... after which you just swap in the flashed ecu
unfortunately you would have the ses light on. you could always have a pocket obd logger or something in the trunk though if you feel somethings wrong.
that's the next thing i was thinking of. i'm probably gonna save up to get the evo ecu cuz you're technically killing two birds with one stone (manual tranny ecu and extended maps for the turbo). I recall GOOSEY mentioned that some of the wires in the boomslang were incorrect (don't remember which pins were wrong).
GOOSEY: any links or additional info on that patch you were talking about?

so roman bc the 03 wont pass inspection with a 5 speed swap i need to use an 00 ecu. but cant flash it. but other than that just installing the 00 ecu and doing nothing else will cure the codes prob. Right? if so then screw the flash. just do the 00 ecu and tranny swap and then hold off for the evo motor then evo ecu. problem fixed.
no longer a g owner.....:(
Soon to get another.....:)
idk if this has been talked about, but wouldn't the 02-up Eclipse M/T ECU and harness work with no code?? I have an 00 so I wont have a problem with CEL's after the swap and Im going to run the EVO ECU when I turbo anyway, but I am really curious as to waht the fix could be for the 02+ CEL's after the five-speed swap.
Whatever happened to the 500 or so Galants that came from the factory with the Manual Transmission?
