Ive done it successfully with a 173DME for a 89 325e/i hybrid. that would work better than attempting a mail-order tune on a irregular engine hybrid.



I didn't know TunerPro had the definition file for it, or even that they were branching out to the Bosch systems, but Miller Performance does essentially the same thing. Their WAR chip is an emulator that works with the OBDI BMW DME and gives the same tuning capability as a Moates Ostrich.

I recently embarked on a Ferrari project... I may have to check TunerPro for the Motronic 2.5 & 2.7 definitions from a Ferrari 348.

Look for "Wiring Harness/Misc. Electric" at the very end of the parts listing.

The definitions for the VW VR6 on the motoronic 2.7 are available, however I see no Ferrari listed, but that doesnt mean it doesnt exist, or cant be made.

how low would you dare to run the engine's oil pan from the ground

How tall is the engine? Seeing as how the firewall is angled and you want the least amount of angle on the CV shafts, I would think to run it as low as bottom of the cradle, lower if you make a skid shield. This would allow you to get it as far forward as possible.

the engine is 25 tall from the bottom of the oil pan to the top of the intake and it is 23 inches tall to the top of the timing belt covers . the engine bay is 24 inches from the top of the cradle to the top at the firewall and the cradle frame rail are 4 inches tall
engine man JUN 13, 06:28 AM
the first thing that will hit the firewall would be the timing belt covers. my plan is to run the engine oil pan 2 inches below the frame rails and maybe put an aluminum belly pan under it

Interesting swap choice.

If I can throw my two cents in, here is the way I would run it. I would use the Audi pcm and not use the cluster from the Audi, and eliminate the auto transmission, ABS, and Immo from the pcm programming. Use the throttle pedal from the Audi and trick the pcm into believing it is still in the Audi. You would need VAG-COM to be able to run the throttle adaptations, but when something breaks in the future, diagnosis will be easy.
I'd also advise to replace the timing belt, water pump and timing components regardless of engine mileage. You will need to buy all the tools to do it. Don't mark the pulleys and try to get around that....it never works. Baum Tools in Florida sells the tools needed. The cam sprockets need to be "popped" and dialed in or the engine doesn't run correctly and can set a check engine light for incorrect camshaft timing.
Use synthetic oil and buy a good oil filter: MANN, MAHLE....not FRAM
Good luck and I'm looking forward to seeing your progress.

Dave
