SRT-4 swap and DEQ

patiofurnituregt · Post by **patiofurnituregt** » Mon Nov 24, 2008 4:19 am

So I was planning on finishing my SRT-4 swap this summer and get the engine and all the fixings (i.e. gauge cluster, pcm, key/ column). I was wondering how you get around the whole DEQ thing? Does it just not have to throw any codes and its cool? Because I was thinking the whole mismatched VIN on the dash and pcm VIN would not fly....I was hoping to be able to do the swap without having to register it outside of DEQ.

I know theres a handful of members that have down the swap, nitehawk, how do you get around DEQ?

Thanks

use the search function if everything is done up right then you wont thro codes unless you don't have abs but that doesn't matter. if you tell them they might check if you don't say anyhting they wont even know

What do you mean by "DEQ"?

oo ooo! I'll take a guess! Oregon Department of Environmental Quality.

If the PCM was flashed to the VIN and all the other crap to get the SKIM to function properly, the VIN should "match" as far as a scan tool is concerned. And for the external label the dealer should have relabeled it.

But the scan tool will read one vin number and the dash will have a different VIN, unless you can flash the PCM, key, etc so that it is the same as a 2000 neon...

If I'm understanding you correctly you want to know about how to deal with the SKIM by flashing in the correct VIN

Here are two methods of dealing with this

This post will show the the preferred method for reflashing a used Stage 1 PCM for use in another vehicle. This method is preferable, since it gives you two benefits. It programs your PCM with both your VIN and secret key data to your PCM. This is actually one step better than a Stage 1 programmed by Mopar, since it will not set a P0633(SKIM key mismatch) code. This means your PCM has YOUR VIN, not the other vehicles VIN. There's a bunch of tecnical data concerning this stuff. If algorithms and PKI type tech turn you on, let me know. We can discuss it.

Thanks to nastyblacksrt and his dealership techs for trying this and verifying that it works. Since then at least two, maybe three or more used Stage 1s have been reflashed this way.

These procedure are from the PL2000 Powertrain Service Manual.

NOTE: 2.4L Turbo Manual Transmission.
After replacing the PCM, you must program
pinion factor.

1. Turn the ignition on (transmission in park/
neutral).
2. Use the DRBIIIt and select THEFT ALARM,
SKIM then MISCELLANEOUS.
3. Select PCM REPLACED.
4. Enter secured access mode by entering the vehicle
four-digit PIN.
5. Press ENTER to transfer the secret key (the
SKIM will send the secret key to the PCM).

This concludes method one.

Please see the other sticky (Rekey Method)for the alternate method, for use when your dealership does not want to use this method.

Please instruct your dealer to follow the DCX procedures as found in the proper DCX manual, not these, these are intended strictly to show your dealer which procedure is to be used.

You MUST get the original owners VIN for this procedure to work. And before you can start the procedures below, your flashing/rekeying dealer MUST call DCX (Dodge) with that VIN and get the original owners vehicle PIN.

This instructions are from the PL2000 Powertrain Service Manual.
The PIN referred to is a four digit code contained within your keys.

Thanks to ATL-SRT and his tech for finding this method and ensuring it works.

1. Turn the ignition on (transmission in park/
neutral).

2. Use the DRBIIIt and select THEFT ALARM,
SKIM, then MISCELLANEOUS.

3. Select PROGRAM IGNITION KEYS.

4. Enter secured access mode by entering the vehicle
four-digit PIN.
NOTE: A maximum of eight keys can be
learned to each SKIM AT ONE TIME. Once a
key is learned to a SKIM it (the key) cannot be
transferred to another vehicle."

While these instructions might not make any sense to you, they will to your tech. If you want to understand more about the whole Sentry Key Immobilizer System (SKIS) feel free to ask

Please instruct your dealer to follow the DCX procedures as found in the proper DCX manual, not these, these are intended strictly to show your dealer which procedure is to be used.

All I get from that is the PIN is transferred.

I still don't see how the VIN was transferred, and not sure if a 2000 VIN would work. It may, if any pre 2003 VIN does.
The worst thing that can happen is your car would have to meet the model year emissions for the engine/PCM installed, which if everything is swapped, and there are no major mods it shouldn't be an issue. Going to a newer model year engine is perfectly legal/acceptable as long as that engine is used in that car model/platform, which it is. Those are EPA guidelines, which pretty much trumph State/local ones.

My concern was the fact that when I do the SRT swap to get everything to work it will have to be flashed to an SRT VIN. But if I go to DEQ and try to pass emissions and they plug in their scan tool and notice a discrepancy between my dash VIN # and the PCM VIN # then I'll be screwed right?. I Understand that as long as the engine is a newer engine, that was offered in your car the whole thing is legit. But when you do the swap you need a gauge cluster, and it will likely have less miles than mine and that is "No, no" right? lol So that would be considered illegal, atleast if you get caught....which is what I'm trying not to do.

no your neon vin thats in the dash will get programmed in the pcm. not the other way.

patiofurnituregt · Post by **patiofurnituregt** » Fri Nov 28, 2008 12:18 am

Like I was saying all the SRT stuff has to be the same VIN it is likely that I may not get all the parts from the same SRT....So they all have to be flashed to a common VIN, and if the dealer trys to flash it to my 2000 VIN it probably will not work.....I know the dont change the dash VIN to the PCM's.

krc21 · Post by **krc21** » Fri Nov 28, 2008 7:11 am

yes they do. They take the vin and skim from you car(on your dash) and they flash it into the pcm so everything will have your cars original vin.

Post by **occasional demons** » Fri Nov 28, 2008 3:33 pm

They will also flash the mileage from the 2000 pcm also. But the cluster mileage will not match, unless you get lucky enough to find one with the same miles.
