Greetings,

I've been studying the Simos18 manual to get an idea of whether this is possible.  I know APR has a 980cc injection kit that they have developed

Quote
While the system is essentially plug-and-play with the included mounting hardware and wiring harnesses, the factory ECU is incapable of controlling the new setup without significant modification. APR’s Calibration Experts spent months fully recalibrating the factory engine management system to operate with both MPI and GDI injectors. New sensors were added to the system to provide the ECU with accurate closed-loop control, rather than resorting to risky tricks or external controllers. The end result is simple. More fueling headroom and more power!

I assume because it is coming with a fuel rail and a host of other components that the US/North American version did not come with any form of Port Injection.  The model in question that I am interested in is a Euro model that came with the very tiny 118cc +- port injectors.  I would like to use the same 980cc injectors APR is using as geometrically they fit perfectly.

I've studied the CBMD, FMSP, INJR and LASP modules to get an idea of how:

1. I would manipulate the ECU into using MPI-DI mode for the Homogenous Mode (Manipulation of Inhibits and DI/MPI/DI+MPI modes using the ID_IDX_CMB_MOD_INJ_etc plus other tables)
2. I would scale in 980cc Injectors (So far I've found the dead time / fuel mass / pressure / temp tables)
3. I would apportion the fuel calculation more towards the MPI (LOST HERE!) to take advantage of the greater fuelling capacity

So far I've found absolutely no resources at all, I can only assume that this is because of the commercial viability of this platform, which makes sense.

Any assistance will be greatly appreciated.  I'm losing my mind trying to scan through these modules and make sense of exactly how the fuelling is apportioned between MPI and HPDI
when in the combined DI + MPI combustion modes.  Potentially useful maps I've found in this regard are:

For enabling lambda control for MPI as well as DI

lc_fmsp_mpi_hpdi_mod_ena
lc_mff_hom_sp_split_up_cor_ena
lc_mff_add_lam_ad_out_split_ena

c_fac_mff_mpl_inj_hom_man[ID]

Some pertinent RAM variables:

fac_mff_mpi  - Fuel Mass Flow for MPI
fac_mff_mpl_split_cor[0][X]

If anyone is interested in collaborating to help figure it out, please contact me.  

Regards from the UK,

Hello, I too am currently working on my golf 7r 2017 310hp. I put 400hp RS3 injector without setting my STFT and LTFT are between 0 and 5% so good. While I think I have a lot of correction but not at all I think the Injo of 7r 310hp = Rs3 8v 400CV.   What do you want as a setup?  Moi stage2 decat, admission VWracing, HPFP kit vis stage1, injector rs3 390CV to sp98. I wish to ride at E85 is have 420CV and 550nm in this config

Is there much difference in the size of the RS3 injectors over the 7R injectors? I would think they may be very similar, considering the similar cylinder volume.

Yes they are similar.  What's your project?

It sounds like the thread originator is trying to add high flow rate port injectors like the APR, UM, and Eurodyne software available in the US support and they are trying to find out how to scale the MPI/DI split as well as the MPI injector constants to work. These injectors have 4x+ the flow of the R/RS injectors so fuel trims won't work like they did for you.

I want to do the same on my car.
MPI completly turns off as soon as you make a bit of power.
It only idles on MPI injectors.
As soon as i have time to work on it i will post results.

If you guys want to create a chat group on whatsapp or facebook I have all the maps to switching split , scaling different size port injectors , how to control during certain torque and enabling on USA cars and much more.

That would be an awesome Idea, I've been emailing with Mike about this but I am sure he(we) would be very interested in having your knowledge on this one.

Good idea to us all we could do something clean

Would be a great idea. My personal car is Golf Mk7R that came with the tiny factory port injection. I'm going to try and get the port injection working at full load and then from there try and upgrade them to bigger units. If anyone wants me to test some ideas and report back, I'd be happy to do so.

Does anyone know if there's any factory injectors that have the same form as the mk7 but with higher flow? I ask because the APR kit is very pricy in my country

For injector looks in the USA (nostrum Energy) very high flow
~ 1200cc Special ea888.

Tomorrow I'm testing the injector calibration to drive ethanol. I have to locate map that I will test (including 1 map one would say KRKATE Bosch to follow) if I happen to have STFT and Ltft good

What's the point to fit bigger DI injectors for E85 when you can just fit bigger port injectors, which is much much cheaper.
You can buy the needed components and it's all bolt on.
