So I took my car to LA to get smoged and the place couldn't complete the smog due to the ecu being hondata flashed. So I bought a stock 02-04 type s 6speed ecu and tried to plug but it didnt start. After a little research I found that I needed the stock injectors. I have ordered them and they are on the way but with further research, I found that in order to have a reflash done you need to send in your ecu, vehicle key and immobilizer. So I guess my question is do I need to get a stock immobilizer too? I purchased the vehicle last year and the tags were good till dec and I thought I had a guy that could pass it but I guess not. It's a stock motor with a turbonetics turbo, turbonetics wastegate, spearco intercooler, hks blow off valve, hks turbo timer, upgraded injectors (440cc), ktuned returnless fuel rail system and it's 3" straight piped. So my plan was to swap the ecu and just turn the boost all the way down (cause I have the boost knob mounted inside under the steering colum) and not over rev it when i drive it to the smog shop. If needed i was thinking of swapping the wastegate spring for a 1lb.

Any help and instruction would be greatly appreciated. Thank you in advance.

You don’t need a new immobilizer, you just need to have it matched to your ECU, but the stock ECU isn’t going to fix your problem. The turbo is going to have to come off as well.

So if I matched it to the stock one I would have to match it back to the chipped one. Not sure how much it would be but I was thinking that I should have all the parts needed that I swap when getting smog done and then swap back. So the turbo absolutely has to come off? So I would also need to get the stock exhaust manifold and downpipe? What if I get kpro would that make things easier at all?

Unless this turbo kit has a CARB EO number, it absolutely needs to come off, and yes you would need a stock header and cat. The turbo would have to come off strictly for the fact that it’s not legal. It’s a hefty emissions fine. Pretty sure state law also requires that you have at least 1 muffler.

As for Kpro, you should get it anyways. More power to be had. Are you sure you don’t have it already? Never heard of a reflash for a turbo

I'm not 100% but I'll send a picture of the ecu the only difference I see on the flashed ecu is there's some pin connectors that were soldered onto the board. As for the turbo the smog place is a pay to pass. So basically if I had a can that I know cant pass they will pass it for a hefty fee.

Your flashed ecu most likely has the immobilizer disabled as well as the secondary o2 sensor. What you really need to check is if your flashed ecus's vin number matches the body of the car vin number. You can do this with a simple obd2 scanner.

Also just curious as to the reason the turbo would have to come off?
Because of the smog test visual inspection. You will fail, just based on that. None of that equipment is state certified.

Ask around for a smog station that will certify you for a price. Ask Body shops, repair shops. They are only $200 some. Cheaper and faster and easier than any legal alternative

Well I know the immobilizer isn't disabled because I just had a key cut but I didnt get it programmed to the car and it wouldn't start.

If you mean "Pass or Don't Pay", that's not how it works.

It doesn't mean they will dishonestly pass you if you pay enough. It means, if you don't pass, there is no charge for test.

Or maybe they do have a "Pay to Pass" sign, I don't know ??

So I'm taking apart the steering column and there's a wire made into a ring around the immobilizer coming from under the dash.
