Check around the breakers for one of the same GEMS/Bosch model. Once installed you will have to have the security codes relearned/synched.

This is the first I've heard of a engine ecu giving such problems...
I would be investigating the possibility of damaged/shaffing wires

If you swap the Ecu, might need to get the key fobs and ignition/ lock cylinders too.

The engine ECU has nothing to do with locks or ignition. Those codes are stored in the BeCM. If the ECU is swapped he will only need to go through a resynch/learn of security codes. however he SHOULD have the adptive values reset as they would be trimmed for the previous engine.

I have the ECU that you need for a couple of hundred bucks on my website. I know that my competitors sells it for
450-500 bucks which is crazy IMO anyway it can go out in the AM if your interested. If not a simple search on Google
showed a company that rebuilds them.

The three numbers you quote are for early, mid and later GEMS cars but not whether or not they use oxygen sensors, that would be market dictated. You need to find someone with a copy of Microcat so you can enter your VIN number and it will then show what was fitted to your car. Unless you have removed the oxygen sensors and want a replacement ECU for one that doesn't use them.

That's a ridiculous price for a secondhand ECU which would be no good to andro anyway as they will have come from a US car with 4 Oxygen sensors and he wants one for a car without any. I wouldn't pay more that £50 for a secondhand ECU.

Would the engine even run if the ECU was "burnt out". What diagnostics has been done ?

UK ECU will work with just two O2 sensors, but vehicle might not comply with US regulations, because the post-cat sensors will always read zero on diagnostics. GEMS Market setting os factory set, so you definitely cannot change it with Nanocom. Not sure if other diagnostic can change this, but ECU Chip specialist might be able to.

Plenty of UK GEMS on eBay for £25 or less. All you need is Syncmate or Nanocom to make it work with existing BECM.

andro is in Russia so US specs are irrelevant, If UAE spec had no O2 sensors, then an ECU from a UAE (or other country that doesn't use O2 sensors) spec car is what is needed.

oops. just looked at original thread dates, realised it was a resurrected thread.

Andro,
Maybe best answer is to check with an ECU specialist to see if they can reprogram the GEMS factory settings to disable the O2 requirement ? Then any ECU could be used.
