My mates brother has got a spare Audi TT ecu for the BAM engine been offered it really cheap, just wondering if it would fit a vRS engine without blowing the engine to pieces.

Any help greatly appreciated!

Thanks

Cant see it working as the BAM has extra sensors to the AUQ so will be looking for signals the car doesnt have. Plus it wil be programmed to run a K04 turbo.

Unfortunately it's not a quick and cheap upgrade to a 225hp engine.

oh bugger, he has the K04 with all hoses, oil feeds etc as well due to a big power upgrade.

What a bitch, what are the main differences aside from the ecu and turbo and the sensors that have been mentioned, might be easier just to swap the friggin engine over!

Yes, swapping the engines would be the best way of going about it!

I too would be interested in the ACTUAL reasons why it won't swap - ie sensors etc. does BAM have variable valve timing actuator for example - I can't imagine the sensor set is much different otherwise?

Is there any chance you can have the lid off the ECU and note down some reference numbers from the Flash chip (ie is it AM29F400B or AM29F800B?) and the circuit board itself ( ie is the reference number on the copper layer of the board 1 268 318 734-9 ?) What is the VAG reference on the ECU label? (ie something like "8N0 906 018 xx" or "06A 906 032 xx" ?)

I have been investigating the cross compatibility of the 1.8T 20V ECU hardware across the range too just out of plain curiosity...

One other significant aspect to not lose sight of, is the issues of needing to match the ECU to dashboard/immobiliser on your car. It will most certainly not run "out of the box" as the immobiliser will get in the way.

Seem to remember an ibiza cupra did this upgrade, KV04 and ECU from a KV03. Worth doing a search on seatcupra.net.

you could get a BAM engine and run it off of a vRS ecu as the extra sensors wouldn't do anything but the other way round it would be looking for certain readings and not getting them so throwing up error codes all the time.

What extra sensors are on BAM compared to AUQ?

Ok then aside from the ECU would fitting a K04 Turbo give me any more noticeable power (with a custom remap carried out afterwards of course)?

Exhaust temperature sensors are two I can think of off the top of my head.

I can see no logical reason why it would not be possible....

doing the K04 upgrade with all needed parts and software should see around 250-260bhp

Dropping the engine in would be a nice little upgrade

Can't see it would ever be worth you changing to a BAM engine as it's mechanically very similar, save for the turbo, although I've been told that stock, they are stronger if you are running silly power. My Elise engine is a BAM job, mainly used for the K04.

Best bet is to source a 2nd hand turbo (I've been told Impreza?) and uprate injectors & you'll be moving nearer the 300bhp mark with appropriately upgraded exhaust, intercooler and ecu re-map.

I'd have thought more in a VRS? My Elise is running 262bhp (conservative rollers at Emerald) and you can imagine how rubbish airflow is compared to something mounted in the front of your car.

Wek when you consider an Audi TT usually remaps to 270 bhp it aint going to be anymore than that.

the BAM engine has stringer rods, better pistons and a better flowing head not to mention the bigger turbo/bigger injectors/better exhaust manifold etc

very few miles on this BAM and driver is not a loon.

edit again:BAM is the engine code

Crank failure maybe?

Have seen a few go. Also had two less than 2000 mile Audi TT's with the BAM engine drop valves.

that's a mutual friends from scn . apparently oil feeds to the crank get/got blocked,and stop spraying the crank= exit stage left

I had heard about the crank oil feeds not sure what causes that. Poor manufacture or poor servicing.

Are you sure about the better flowing head as I know Wayne from Pro Alloy and he uses an engine from the 150bhp Golf and apparently, that flows better than the BAM coded engines? He also has it revving to 7800 with a different turbo, which I wouldn't mind!!

It might have better pistons, but all 1.8t's are forged anyway. Don't know about the exhaust manifold as mine has a custom Jabbasport one, which I guess is needed for the Elise install.

270-280bhp is quite realistic for that engine with better airflow and an uprated intercooler. That's what my mate saw in his Mk2 Golf.

I've certainly never heard that before, so I think it must be a small problem. Biggest, of course, is coil packs!!!

I know people that race with them too and bear in mind they have more stress than FWD installs in a RWD car & there have been absolutely no reliability issues.

i bet mine gets more stress than yours

4WD and 14 tonne driven like a **** :P
