Syncronising ews/dme with inpa/gt1

[MrChrysler]

I got a DME from a same model, with the same transmission variant.
Now I need to sync the dmw with ews, someone told me to use inpa/gt1. I dont know how to do it, and what is gt1?

[GSXRliterbikz]

You need to have the dme wiped. Can't just sync it.
Pm dima (dumdd). He can do it for a reasonable price and he's a supporting vendor here.

Yea, what he said

[setconstr]

Yep , DUDMD is the man, $200.00 is what he charged me to virginize the used DME I purchased on Ebay and I used Progman to sync it works perfect I couldn't get Inpa to work for me.

[MrChrysler]

He told me that if it's 96-98 it's just a matter of sync.
Can someone tell me how to use inpa to do it?

[setconstr]

I found this but for me i could not get INPA to sync my EWS and DME ( INPA can easily syncronize the DDE/DME with the EWS. First get the ISN from the DDE/DME from the coding section of the control board by pressing F3 (atleast by my program). write off the ISN then go to the 'activate' part of the EWS. Press F1 (Writing ISN) and simply type the characters you read off the DDE/DME. Press OK and voila!! the EWS and the DDE/DME are synced ) Good Luck ....

Interesting...so basically you're saying that the EWS control module's ISN can be overwritten...using a different/new ISN from a used DME? If so, I didn't know that...I was under the assumption that it was a write once only thing.

And then I'm still confused because in order for the car to start...the ISN in the key's transponder, EWS control module, and DME/ECU all must match. If you put in a used DME and you can actually overwrite the original ISN of the EWS-CM with the ISN of the used DME...how do you get around the ISN in the key's EWS transponder which is still the original ISN that matched the old DME's ISN?

I'm sooooo confused when it comes to installing used DMEs & EWS control modules.

Then if you have an older e38 that has EWS 2...you also have the transmitter receiver module (which was later incorporated into the EWS-CM when EWS 3.2 debuted)

I dont understand where to find "activate" part of the EWS. Everything is on "engine"?

[MrChrysler]

Anyone?

[daytonatrbo]

INPA can re-sync the EWS3.3 rolling code table between the EWS and the DME. I'm not sure that it can do anything beyond that, and I have no experience with anything older than 01 when it comes to that stuff.

I don't think INPA can change the ISN, you'll need something a little more heavy duty for that.

INPA can talk directly to the EWS module. I assume that's where setconstr is talking about the ACTIVATE option.

[MrChrysler]

So it cannot be done with inpa? So which program would make it work... DIS? any other?

[setconstr]

I did it with " Progman "
Using the GT1 Diagnostics Tool

1. Connect a battery charger to the battery of the car and set it to 13.5 Volts. (This is important
   because the voltage cannot drop below 12 Volts during the synchronization.)
2. Use the Round connector of the GT1 and connect it to the car. (Do not use the OBII Port for
   this procedure.)
3. Turn the car’s key to the ON position. (Do NOT start the c ar.)
4. Wait until all the LED lights on the GT1 are solid.
5. On the main screen of the DIS click on “Coding/Program”. (If “Coding/Program” is not
   available, use the Progman and follow the instructions below .)
6. Then click on “Alignment EWS -DME”
7. Follow the instructions given by the DIS

While the DIS synchronizes the DME with your car, you will need to wait a few minutes for thisprocess to be completed. Also , you might need to turn the car’s key to the ON and OFF position, butremember to NEVER start the car until the process is finished.
Using Progman to synchronize the DME to the car:



Follow steps 1 -4 of the previous procedure.
Open the Progman application.
Choose your car and chassis.
Wait a few minutes for the Progman to collect the ZCS values.When it asks for retrofits select NO.
Select EWS Calibration
Click YES to start the calibration
Turn the car’s key to the OFF position and click continueWait 25 se conds.
Turn the car’s key to the ON position and click continueClick Finish
Start the car

Not 100% sure on that, but it sounds to me like its beyond INPA.

[Qsilver7]

Is everyone on the same page in this thread? I ask because it starts out with the PO wanting to install a DME from a totally different car. As mentioned in the 2nd post...the DME/ECU needs to be wiped (not just resynced) because it has a different ISN and the car won't start when the EWS control module and DME have different ISN's asssigned to them.

The last few posts are about synching EWS...which is about resynching the EWS control module & DME/ECU that already have the same matching ISN. Again, the OP is asking about installing a used DME/ECU that has a totally different ISN written to it...you can't sync a DME & EWS-CM that have 2 different ISN's written to them.

Or am I the one that is confused? :

[setconstr]

Read what He said we Told Him to get it virginiized and He said DUDMD told him that He could sync the used DME He has so we are just telling Him how to do it so maybe you are confused or maybe we are all confused. I had to have my used DME virginized by DUDMD and then used Progman to sync it i couldn't do it with INPA.

Thank you...I consider myself confused...I misunderstood the post where dudmd responded to the PO....I didn't know who the "he" was...I read it as it being the person that sold him the DME told him that...not dudmd.

He told me that if it's 96-98 it's just a matter of sync.
Can someone tell me how to use inpa to do it?

[setconstr]

You are right I'm confused . I'm with you I don't think it can be done and He could mean the guy He bought it from not DUDMD......

[daytonatrbo]

The service that DUDMD provides is for blanking the rolling code table in the DME so that a different EWS 3.3 module can burn it's own rolling code.

Since OP's car is pre 3.3, that is not necessary. Only the ISN re-write is necessary, I just don't think anyone that has successfully done that has appeared in this thread to advise.

[Mayorchuck]

Towed to Diag forum.

[legoman67]

EWS 2 can be completely resynced with a totally different DME. No virginizing.

EWS 3.3 cannot be. In the 3 series, 97 (e36) was still EWS2. EWS3.3 didnt start till the E46. Not sure when it changed for the 7's.

[bubbafett]

Interesting...so basically you're saying that the EWS control module's ISN can be overwritten...using a different/new ISN from a used DME?

Someone correct me if I'm wrong here, but I believe that is true, something about how the modules talk to one another, which one goes first, then the other one syncs. I thought and have read several places that all that is needed to sync the EWS & a used DME was to use INPA or DIS (with no wiping of the ECU). Can an expert chime it.

how do you get around the ISN in the key's EWS transponder which is still the original ISN that matched the old DME's ISN?

The key transponder and the EWS are paired for life from the factory, there is no rolling code between them. But you can buy a new virgin EWS and be synced to any ECU. Because the ECU communicates first to the EWS and gives it the rolling code. To my understanding this is the same process for a used ECU.

Below is an EWS chart and when the various changes occured (from EWS I to EWS III D):

[MrChrysler]

Ok, so I just sync my DME with EWS... The car starts, however after few minutes of idling something weird happens, and the engine works on 5cyl. 5.6.7 are not firing.

I think that after 2000 british pounds invested into the car, it is ready for a scrap yard.

This type of problem can be indicative of a defective cam or crank position sensor. Electronic components like these, and coils usually start to break down after they get warm. Having a V8 is an advantage in this instance as at least your troubleshooting only needs to involve controls for one bank of cylinders.
