2 Injectors, 1 Driver: E38 running 16 injectors bathched Does anyone have data or knowledge of the capability of the e38 computer to run 2 injectors per driver....wired in parallel or series? I am looking to put fuel above and below an old 6-71 blower so need these 16 injector for placement/location not flow.
My understanding is that the e38 can run them fine, with no impacts to timing events or such... but that the increased amps will cause the injector drivers themselves to burn up. Wiring in parallel will cause an increase from 1 to 2 amps per driver, while wiring in series will cause the injectors to get half voltage, which will impact both timing and flow, and MAY be able to compensate with tuning, but this is unproven.
Looking for some specs or engineering data on the drivers used in the e38....or some educated guesses that it will be able to handle the extra amps.
Thanks!

I've used aftermarket ecu's with 2 inj on one driver batch fire without issue. Cant comment on the OEM though. I would definitely not try and connect them in series though, and they absolutely would need to be high impedance injectors.
But if you did just run 2 inj of each driver, you would still be full sequential which is good..
Or just run big single injectors and a driver box ?
