ECM swap questions

I bought a used ecm off ebay and they told me it couldn't be flashed due to the old vin number being locked with the immobilizer. Has anyone had this happen to them? They said a used ecm can't be re written. Where do I go to get a new one?

 

Whomever told you this is lazy, a liar, and or uninformed.

 

They said they couldn't start the truck with the ecm. So they could try again if I got a new one. A brand new not used one. This is the Toyota dealership here

 

Try a different dealership. Don't mention what the previous dealership said.

 

I live on kaua'i in Hawaii I'll have to ship it out somewhere for a new dealer to flash it

 

So they come back and tell me they didn't clear the vin off the ecu before trying to write they're trying again

 

We only have one dealership out here lol it’s all the same company it’s a monopoly

 

Yeah bro we have 1 toyota dealer here on kaua'i next place would be oahu

 

And we only have one lol

 

Now in being told they need a code from a dealership in the mainland so they can clear the vin to write a new one

 

Vin doesn’t have to match .. but make sure you have the correct ECU model for your year .. this will work !

 

Umm .. are you trying to replace to ECU and having issues with the immobilizer ?

Or .. trying to load the TRD tune to another ECU ?

Either case .. the dealer is being lazy. You can load it yourself with a 2 day sub to techstream, but will need a mongoose cable.

 

Trying to load the TRD tune to a stock one..they say even with the code it can't reset the vin number attached to it. I need to get a brand new ecm is what they say

 

How do I do it by myself?

 

Techstream .. with mongoose cable.

 

I understand that part ha. What I mean is, do I download the software to a computer and then what? It has the trd tune in the tech stream? How much is said tech stream and a mongoose cable

 

The only time I swapped an ECU was in a GM car. Only needed a Tech II to reset the crank position sensor. Other than that, car started fine. Is it not this simple for Toyota's?

 

2 day subscription for techstream is $50. Mongoose cable can run you $200+ Used / $500 new.

Techstream will have the trd calibration file to load.

 

Post in : performance and tuning section.

Someone might be nice enough to load the tune for you. Obviously, you would have to mail them the ECU.

 

I searched on Amazon and found some for less than 100$?

Also found the techstream plus sale for less than 100$ too. Legit ?
