Re: V12 M73 to Audi trans, with Proteus in Lamborghini Replicas

No doubt that's better and more flexible, I was just thinking about what knobs could be turned today not suggesting it was anything beyond a possibly functional solution for this very specific case where an idle/low power mismatch is occuring.

Re: V12 M73 to Audi trans, with Proteus in Lamborghini Replicas

Looks great! Idea. On the bank that is rich, change the TB closed position to tell the ECU 0% TPS is actually just a little open on the TB so it will never close quite as far. You can balance the idle mixtures this way and the error should go away as the TB opens so I think between this adjustment a...

Re: Classic Mini 5 port injection (siamese ports)

There should be no problem at all connecting one injector to two drivers so it is pulsed twice as long as you stick below about 45% duty per pulse (90% total) simply for reasons of burning out the injectors windings with too much on time. Something I doubt you will be able to do anyway. I think you...

Re: Classic Mini 5 port injection (siamese ports)

On a Siamese port setup the big issue is the ONLY way to know the fuel you're injecting is going to the cylinder you meant is to only inject when 1 and only 1 intake valve is open, Due to wall wetting effects and such, this isn't how it works. Don't bother trying to trim individual cylinders on a s...

He didn't drill another hole, just put a sensor in the spark plug hole to test at cranking speed.
which I'm pretty sure gave him a number that is a few degrees before actual TDC...but as long as he's setting adjusting timing on the dyno it will all work out.

I'm sure the addition of the second plug adds power - I don't doubt that. I doubt whether staggering the firing does anything useful for power.
Yes, I was agreeing with you in a long winded way and suggesting a rewire to remove that feature and make it direct fire of both plugs together

I bet the staggered firing is an emissions thing.

There is no reason in the world to do that if you have 12 fuel and spark outputs in 1 ecu. That's not what I mean - I just mean having two map/maf/tps and doing independent per-bank fueling on a split-manifold engine. There are two interesting cases, N=1 and N>1, and once it's N>1, N=2 and N=4 are ...
