Porsche 911 stand alone ecu and throttle body set up.

[wildoliver]

I'm looking for a bit of help.

The time has come for me to start playing with the 911. (3.6 964)

I am looking at fitting throttle bodies which don't concern me.

The injectors also don't concern me.

The ecu side of things I need some help with.

What I want is a system that doesn't rely on a MAF sensor, I want little or nothing in the airflow down the TB's.

So I'm looking at a system that will use a crank position sensor and whatever else is needed to do the job this is the point I don't really know where I am, I'm going to be doing the job myself, except mapping I would like the maps to be done by someone with experience so I get the most out of the car.

What systems are available? Megajolt look cheap can they be used? I want to keep costs down, I don't want the electronic side of the job to exceed 1K really, if it can be done for less great, I imagine one prob I will come across is most of these kits seem aimed at 4 cyl cars with 1 distributor, mine is a 6 cyl with 2 dizzys and 12 plugs.

Anyone with any advice?

Hmmm i know the motec set up and to be honest I really can't justify the cost.

Are Omex good? Never actually heard of them before?

[wildoliver]

how would you set the distributor/coils up to trigger though? is there an output on the ecu to do this and I assume you would just have to split this off?

[wildoliver]

Sorry didn't explain myself very well, Old cars had points, obviously mine is pointless, so on a car that you took the points off and put electronic inition on you would put a small control box on, which I imagine is replaced on my car by the engine ecu, so does an aftermarket ecu have an output to trigger the coils?

[wildoliver]

You know when you don't know the answer to a question and in answering it someone makes you feel like an idiot for not knowing the answer in the first place?

[wildoliver]

Thanks thats actually a handy looking book.

I did know that ecu's control timing and fuel, my original question if you look up was regarding splitting the signal from ecu to coil/distributor as there are two on my engine, I assume that is the way around the problem?

[wildoliver]

Brilliant thats been a big help I'll let you know when I'm on the next step!

[wildoliver]

The main attraction is to lose the poor inlet system, without going down the route of PMO's.

[wildoliver]

where abouts are you nick, would be good to see an installation even if on a 968 just to see how it all goes together.

Ok if I'm down there anytime soon I'll email you cheers mate.
