Has anyone done a DME EWS delete on their cars?

I’m considering it so I don’t run into issues later. The DME is basically fried... chicken

Thanks!

I'm pretty sure I haven't done this, but could you elaborate? What is EWS?

It's the electronic lock out system for the keys

A new ECU will run $1800, something I'm not willing to pay.

Refurbished ECUs can be found for around $200. Is there something special about the ZHP ecu?

Also do we have an MS43 or MS45 ECU?

Nothing special. I don't know what year your car is but the later years are MS45.1. You should be able to tell from the label on the DME

Could you find one out of a junkyard and have it coded to your car? Is that even possible?

Just looked into it. ZHPs have an MS45.1 DME which is not as easy to "hack" as the MS43 DMEs.

I've found a handful of people who can work with it, and it looks like it'll be $500+ to get it fixed.

No fun.

Ews delete will not do you any good if you do it to your existing DME and then it takes a shit. As soon as you put another DME in there it's going to be locked with the ews again. deleting ews in an existing DME just means that you can take that DME and put it in another car with no issues on starting it.

No clue, which has me a bit worried about sticking a new one in.

This guy will clone an old DME to a new one and has a bunch of nice addons. Hopefully he does it right. I will be reporting back in due time. I don't think I want to do the EWS delete for $350. The Euro-Tune for the secondary O2 sensor and secondary air is tempting, but if the communists bring emissions testing to my city, i'll have to have the DME reflashed which is stupid.

I’d like to give a quick shoutout to kasselperformance; The clonsed DME worked. Didn’t have to do an EWS delete, he transferred everything from the old DME to the new one.

.... And it's dead

My worries about the underlying cause of the fried DME might not be solved.
I have no clue what would cause a DME to fail -_-

My first instinct is a low battery voltage. The battery has needed replacing for a while, but this shouldn't cause the ECU to fail.... no?

I would think it's more like water getting in somewhere it shouldn't be getting into, causing a short. Or perhaps a bad ground or something...
Do you see any physical evidence of the DME being affected by external elements? Water stains, corroded wiring, etc.?
