Hi guys
Anyone have any experience of stand alone ECUs, and which one to use, thinking of putting of 48mm ITBs on my 996 3.4 with cable throttle. and need to sort MAF out which no longer has a home.
Thanks in advance
Alan

I'm building a very similar engine/car. Are you planning yours to be road or track? Will you be using any form of cold start facility? smile

Can I ask what you are doing and trying to achieve? Have you looked at airflow rates and decided if ITBs are actually needed? with stock redline the 3.4 doesn't ever run out of air as far as my info goes.
For the price of a ecu,wiring and ITBs you could probably fit a later 3.6 with x51 or build the 3.4 out. This would likely give larger returns for example but without knowing where you are coming from it's hard to really say too much.
I'm never one to discourage car mods that's for sure but there's not enough info there to really get into it with you.
If you want your car to be quicker then suspension and brake mods will yield more however if you only drive on the street then it very possible that this usual avenue of attack won't be as beneficial and indeed simply more power will be the only real path.

I thought very seriously about doing this...

There just doesn't seem that much info out there on a 3rd party ECU that can talk to the Porsche loom and instruments, engine sensors etc and that is where it gets very expensive.

I still think it will be A LOT cheaper than opening and upgrading the engine and I am sure there is power to be found, though cam timing may be worth having a look at as well at that point.

However, my car has all the fancy suspension bits etc so I was at a loss as to what to do next anyway...
