Pro 16 going on an Aston V12 from a DB7.
From factory (like every V12) these are dual ECU. Each plenum has its own throttle body and is completely separate air from left to right banks.
The software supports 2 banks in the VE section, but I don’t see any other bank separation in parameters.
I feel like I should have 2 IAT sensors that correct separately, close loop O2 the same and because this engine’s plenums aren’t joined at all, 2 map sensors.
Can anyone shed some light on how this is intended to work?
I was looking at this as oem ecus got wet and they not good anymore .
i would assume and run this as common plenum there should be much ve differenced between banks and IAT differences too…
what are you planning to do with coils ? run 12 active coils ? is there space under intakes for it .
are you planning to retain misfire detection system ? im planning to do more research how is actually working .what signal system checks.
There is no direct support for dual plenum engine configuration.
We want to do it, but it’s a big task with low demand, so it has to wait for now.
There are some custom things you can do.
Add a second MAP as a custom sensor and use it for the axis in the second VE.
Make corrections based on the difference between MAP/IAT sensors.
Remember, you can put any channel on any axis in any table, including custom functions and math, so if you really need it, you can do a lot.
Yeah this was what I was leaning to, but it will probably require more of the calibrator.
You mean like a number channel that chooses the greater of the two IAT sensors for the ignition correction?
It will have 2 lambdas so should be able to see if its getting too far off. It’s also a stock engine, so I’m not that worried about tuning margin as it wont be a 10/10 stressed car.
One of my selling points with the Pro16 on this engine is that its so flexible. I can try multiple different methods and see what’s giving the best result, budget allowing of course.
@greg its already got 12 of the 3 pin coils, so yeah lol running sequential ignition and injection. We’ll use two knock sensors and calibrate as needed.
The factory ECU’s do have a communication of some kind to keep the banks ‘synchronized’. I’m not 100% on whats done with that data but I know its there for a reason.
You can use per-cylinder correction tables.
For bank one cylinders, add IAT 1 as the axis.
For bank two cylinders, add IAT 2 as the axis.
You can now make independent corrections to fuel and ignition.
The only downside is that you have to copy the table for each cylinder.
You can save the table to a file from right click and import for other cylinders.
