M50B25 Turbo basemap?

Post by KevinC » Thu Jun 04, 2015 11:18 am

Hey Guys,

We are busy wiring up and finishing everything around the engine.
It concerns an M50B25 Turbo. Wiseco low compression pistons, ARP head, main and rodbolts, new bearings, Athena headgasket, Siemens 870cc injectors.
Is there a basemap for this type of engine or will it run without good map on the EMU Standalone ECU?

Thanks!
Kevin

It is too hard to send base map because nobody from here knows how the emu is wired to engine - outputs inputs sensors and etc ...

Hi Kevin!

You need to confiugure and make tables for your engine setup.
We can help you for sure to get engine start and running.

I wired up all the sensors, plugs and injectors.
then after three or four times of cranking, while adjusting the primary and cam trigger edges, the engine started and runs.
I used the very stock VE and IGN maps, with every cell the same value. VE was all 40, and IGN all 10.
So if your engine doesn't start, there has to be something wrong with your basic settings

This is wired as user manual - injector 1 on injector 1 and ignition 1 on ignition output 1 ......... the link you provide there are errors ignition 6 is written g14 but it is injector 5 in manual - please pay your attention when wiring anything on cars

Hi Guys,

Thanks for the replies so far.
My loom is made by Greg from RRR Engineering in the UK, he is also a EMU ECUMaster dealer.
He is kind enough to help my getting setup through teamviewer when we're so far (y)
