So I've read that cobb/ecutek will invalidate CALID/CVN for smog purposes.

 

Hypothetically, would it be possible to flash an OEM tune at a dealership so that it doesn't trigger anything during a smog check? 

 

For example, would it be possible to swap in a set of 2020 nismo gt3 turbos, and flash a 2020 nismo factory tune and pass smog without incident?

CALID/CVN is a checksum. Flash the stock tune and the checksum will be the same as stock. So you will pass smog check if it's looking for that.

No, 2019-20 have different ECUs with larger memory, and their factory firmware cannot be flashed into an older model year ecu.

When you say flash a stock tune, do you mean a an OEM file at the dealership or a stock tune that's compatible with EcuTek/Cobb?

I, personally would flash back to stock to prevent any future problem that could arise i.e. emissions issues.

This...loading a stock tune does not mean the OEM tune per say.

But I dont know what CA is searching for...the dealer will/can know though

Wouldn't a Motec solve all these issues.

^ I see where you are going with that. Installed and tuned your probably talking $12-15k and how do you not get that fly steering wheel too for another $10k. I don’t know enough about Motec, but think the signed manufacturer tune is what’s actually needed. If it’s just pass ready monitors which aren’t actually ready or even present, ecutek does that.

Hi Droptopp

 

You've helped me in the past in discussions about Ecutek and emissions.  Let me be a bit more specific in my question now, so that others here can benefit from your Ecutek knowledge:

 

If a car has a Map on it...an encrypted Map (whether SD or MAF) as is usually done by major tuners...can the Ecutek device/software deal with things as you just said here WITHOUT creating another Map?

 

I.E., just buy it and hook it up, push some buttons, etc., or are there more complications, perhaps by requiring the making a new Ecutek Map?

If you changed the map/tune while at the dealership for emissions testing, none of your sensors will be in a ready state and allow you to pass. You'll fail on too many sensors being 'not ready'. You'll need to apply a map/tune and drive the car until all the required sensors go into a 'ready' state.
