Here's the reference for the air metering part, I don't have the reference for the fuel distributor in handy as I'm away from home.



I guess Bentleys or RR are quite similar to latest Mercedes.
This one was quite interesting price wise and original engine being huge, I hope won't starve the 930...

IIRC Steve estimated a Merc V8 CIS-e unit capable of over 500 HP.

So...I have a Merc V8 lambda fuel head and Merc V8 CIS-E fuel head. From what I've discerned, the CIS-E unit is the one to use. I already have the full dkubus kit with FrankenCIS WUR. So I just delete the WUR? Or do is still use the stock/FrankenCIS WUR?

Delete it, No WUR exists in the CIS-E arrangement so the FrankenCIS eWUR does not apply to CIS-E installs

you will require the FrankenCIS DPR interface though to properly control the DPR/EHA valve on the side of the CIS-E fuel head
Code:
VW/Audi call it a DPR - Differential Pressure Regulator
Mercedes refers to it as an EHA - Electro Hydraulic Actuator
VW units are grey and Mercedes are black, the electrical connections
are also different, VW use a standard Bosch EV1 style injector plug 
and Mercedes have a two round pin keyed connector 
The valve is basically a metal plate inside an electro-magnet and driven by a variable current rather than the usual injector pulses. The internal preload is offset to require between 10mA and 30mA of positive drive at idle. The DPR/EHA valve reverses current to close against the internal spring preload and system fuel pressure when commanded to lean out the mixture and/or go into fuel cut.

Yes! mechanical/hydraulic constant flow injection can be managed by a modern EMS

Is the FrankenCIS DPR interface hardware or software? I'll have to look online for a DPR, assuming it isn't something already attached to the fuel head.

the DPR/EHA itself is the plastic block on the side of the fuel head

The FrankenCIS DPR interface connect between the Bosch Valve and the MicroSquirt and does the control translation from pulses on INJ1 and INJ2 to current and polarity at the DPR

also be aware that CIS-E is much closer to EFI in implementation and many more parameters in the control system have a direct impact on starting and running an engine properly

The end result is awesome, but the road to happiness is longer.

The road to happiness is CIS with EFI Fidelity. I'm on the right path.

I have not bought yet the microsquirt ecu.
I read somewhere that there is a project with AEM device.
I have the necessity to control my low impedance Lpg injectors too and this could be a good solution.
How much time is necessary to develop this project?

The V3 MicroSquirt® fuel injector drivers will clamp the current flow at 5 amps each, enough to drive one low-impedance injector, or up to 4 high-impedance injectors, per bank. Or for low-impedance injectors you can use resistors (see below). For up to 4 high-impedance injectors per bank, the driver will be fine, and high impedance injectors don't require current limiting (their internal resistance, i.e. 'impedance' resistance is high enough to limit the current to safe levels).

As far as your question about implementation time, not sure what you mean. If you are talking about getting it installed, running, and basic tune it took me months to learn a lot of lessons. I could do it in a weekend from start to finish now including all the mounting etc.

He's talking about the AEM Infinity work to get FrankenCIS operational. AEM is bad ass.

Yes this is what I mean. I would to install Frankencis system but I've also an LPG plant with low impedance injectors and his own UCU that now I can't tune.
Aem infinity 506 has the possibility to control Low imp. inj. without external driver.

But no problem, I will go with MS for the moment.

Thank you guys!

P.s. My road to happiness seems to be veeeery long...........

The AEM Infinity project is still moving forward, but very very very slowly
EngineLab is the company that designed the original system and they then licensed that platform to AEM, if you go to their website https://enginelab.net/faqs/ the software and samples can be downloaded, and if you purchase either one of their ECUs or an AEM Infinity, you can register the product and obtain blank firmware that you can build your own logic system on.

I would strongly suggest nobody spends any money UNLESS they are certain they can devise their own model from a blank base


I'm recording thoughts and progress here FrankenCIS - FrankenCIS Community Forum - FrankenCIS Development

my 928 specific page Project Outline and ToDo - FrankenCIS - FrankenCIS Community

There is a huge amount of work still to do, and no estimated completion date.
In most if not all cases, for the work involved to get the AEM to operate on our engines, it is preferable to simply convert to proper EFI, especially in a dual fuel scenario such as LPG.

Do you intend to convert to Frankencis?
I hope..

Yes, I intend to complete the AEM project

I recently removed the MicroSquirt ECU from my car to encourage me
to drive it on the road again I must have the AEM functioning
No AEM == No happiness
