Ews

What does EWS disable?

[StereoInstaller1]

In the '95 E36 M3 I just did remote start on EWS disabled crank.

Oddly enough, if you had the key within range of the antenna when the car was initially cranked, you would still be able to crank it for about 3 minutes (not continuously, duh, but repeatedly restart the car) after removing the key from the antenna.

What we did, since there are no transponder boxes available fro that car (not even listed) is we used a spare key, unwrapped the antenna coil from the ignition switch, wrapped it around a former and put the key in it, inside the dash.

Kind of a "hack" way to deal, but the guy was on a budget. I am gonna get hold of an EWS module and find out what signal the ECU sees...find some way to bypass that crap 100%.

So it doesn't disable fuel at all, just starter?

Shit, I don't know! I bet it does cut fuel, but cannot for certain answer.

I think it does disable fuel. When I was having EWS issues with my euro s50b32 (EWS II) it would fire up but die immediately. I think the EWS was cutting fuel.

This is just my experience. If anybody has other info, feel free to comment.

EWS in an e30 cannot disable your starter.

[StereoInstaller1]

So if the thing disables fuel and starter, why couldn't you just add a fuel relay, leave the EWS tripped all the time?

[matt]

It disables the spark and injector drivers in the ECU.

Ah ha, so basically a global disable.

What signal does the ECU want to see from the EWS box, is it digital or analog?

[matt]

Hell if I know. It's almost certainly digital.

[StereoInstaller1]

Hell if I know. It's almost certainly digital.

Just what I was thinking too...bastards.

All of the transponder bypass kits require a key for operation, so you might as well use the stock key in the stock antenna.

I am pulling an EWS module sometime in the next 3 weeks, gonna analyze the hell out of it!

[matt]

Don't bother, EWS is too easy to bypass already. All it takes is a chip and wirecutters.

[StereoInstaller1]

Matt, do all of your chips require premium gas?

[matt]

All the chips have 91 octane options, mostly for CA people. There is not a whole lot of point to an 87 octane chip... 2hp is not worth it to most people, I don't think.

What is 93, $5 a tank? Less? It's worth it to me...
