This topic has started as request assistance with buy to choose all options correctly.
However I will need probably more assistance so would like also share gained information with others to help with further installations.
Goal: Fit VEMS to control BMW M62B44(no Vanos) modified engine but still natural aspirated.
Is this page for "Dominik" ?
Cool. minor note: when installing, make it separate page for each project (to avoid disambiguaty)

Dominik's Mercedes V8 engine (if this page is not for Dominik, this section will move) : ECU fits our requirements, but 1 topic must be solved ;
- can we implement 8 high current [ignition drivers] => those would be able to control 2 ignition coils each.
- can we add 8 further ignition drivers to to the 8 ignition outputs (2 parallel on each output)?
yes, Either
- order with 0 IGBT (8 logiclevel), and order comment: "please add 3 clamping plates, and 1 insulatorsheet (3 lines)"
- this allows using an external heatsink to mount 16 IGBTs in 3 lines
OR
- order with 8 IGBT , and order comment: "please wire the 8 internal LOGICLEVEL IGBT gate-drives to endplate flying loom EC10 connector, and add 2 clamping plates, and 1 insulatorsheet (2 lines)"
- this allows using an external heatsink to mount 8 IGBTs in 2 lines
Fitting all 16 IGBT-s inside ECU (although theoretically possible, of course, mechanically could fit) does not sound a good idea. Assembly would be more difficult, errorprone, and cooling might be insufficient (depends on current of course).
The clamping plates are free of charge (if mentioned in the order comment when ordering ... not in email after).

Modified M62 parameters:
Displacement changed to 4734cc
Injectors 257 cc/min 12ohm (Stock S62)
Firing order 1-5-4-8-6-3-7-2
Modified ECU parameters:
I have decide to change case as there was lot of components connected by flying looms.
