Injector voltage and lag

[wurlycorner]

When an engine is running, there can be a supply over 13V due to the charging system

Yep, 14.4v is normal.

Only issue is i HAVE to use windows XP to adjust the greddy settings.

jk, hope you get it sorted.

Nice!

I have a question for you about the tuning on the emanage as I'll be in a similar position too;

What are you doing about managing the AFR's when on part throttle? Having done some reading on the emanage, you can trick the ecu into thinking it's in open loop beyond a certain throttle position so it stops fighting the EMU, but when you're in closed loop the AFR's are gonna be all over the shop as it's trying to correct what the emanage is doing. So the injector scaling will be out the window plus there will be some boost going into the cylinders with no additional fuel.

So, motorway cruising would be the big concern I guess...

Not trying to throw a spanner in the works, but we don't want any engine boom boom after all the work you've done to get it going

Im not even going to start understanding ECU tunning. I know what ECU means and thats about it.

I do know the yanks run them fine. Im aware you can change the thottle %age to when the correct A/F take place.
Im running the stock MAP sensor how it should be but i have another greddy map sensor so it can see boost and vacuum after the charger so the EMU will understand exactly whats going on.
Also the Greddy EMU takes direct control of the injectors meaning it completely overides what the ECU says.

It does in open loop but not closed loop which is where the part throttle issue could be. They sell the ecu with their turbo kit so it should work ok. May be worth asking thor what they do for part throttle tuning...
