Sard Ecu won't work

Guys i just got a SARD Ecu A/T for my supra matched all the numbers and it was correct to my stock one but when i put it in my car i just get black smoke erratic idle ,floods the engine and cut off. Try starting it up and the it's just flooded all i can smell inside and outside is petrol.

After a while starts up and keep misfiring dies but as soon i stick the stock Ecu back in it's all working again without any probs ?? I do have a HKS boost-cut which i set to 12 as that will let through the signal and my car is a TT A/T Bpu anyone can help with this prob??

Not technically minded but i can sure help with the grammar lol

May have been setup for a single or heavily modified car?

it's only supposed to be doing these as it's not remappable

It may be that ECU needs a few miles of driving to set itself up properly. It's the same as if you disconnect the battery on your car and the ECU is reset, when started again it'll run lumpy and not idle properly until the cars driven a couple of miles or so.

If you can get it to actually run try a drive and see if it improves.

mate it floods the car in about 1 min and won't start again + it was pouring out black smoke

yer doesnt sound good but i havent a cluw hows these work... Hav u e-mailed the person/company u got it from?

Whatever's up with it I would suggest you stop using / trying it as bore wash will be the result. I'd send it back and give the engine an oil and filter change.

Have you got a friend locally who could also test it on their car?

Have you looked closely at the ECU to see if any of the pins are broken off/missing?

When it's started is it running on all cylinders? Running on less than 6 cylinders would cause the symptoms you describe.

I presume it was running fine before, is it just the ECU you've swapped, nothing else messed with?

Have you tried putting the old ECU back on to see if it starts and runs okay?

You could also try checking for fault codes, although if it's hardly run it's may not have logged any.

You might be right think i will have to send it back and yes the old ecu works fine. no fault code at all there is no engine light that comes on

I had the EXACT same symptoms with a stock ECU in a TT a few months back, and the only fix was a new (used) ecu swap.

Ok cheers guys i will send it back as faulty then seems to be the general response

thx for all the help
