This will be a great data point. Given the effectiveness of this on other fuel distributors, this could be very close to a providing the slam dunk decision maker to everyone considering converting every SC on the planet to a turbo (or supercharger).

This is extrapolated data from FastEddie's 924 tests

if we can get a few verified data points for each model head we can build an injector profile like the below for each one

we need:
- system pressure
- air plate position (mm down or up from rest) max designed throw is 37mm see post by Grupp-A
- FV if present should be disconnected from the lambda system and fed 12v
- cc/min for one injector

No I haven't made any progress with FrankenCIS. What I have done is recently split my fuel pumps into 2 circuits and tested the voltage available at the pumps. In stock configuration my red relays and associated fuses would get HOT after a 20 minute drive. Now the relays and fuses are simply warm.

I want to do more work on the wiring to the pumps as I'm currently seeing a 0.5V drop to the front pump and 1.5V (!!!) drop to the rear pump.

Once I minimize the voltage drops to the pumps then I'll move on to testing the FV.

Information received this morning regarding Euro non-lambda and US lambda fuel heads

measured maximum fuel flow appears identical between Euro and US heads when the Frequency Valve is driven to full rich on the US unit.

matching that data with the 924 info posted earlier
Frequency valve control range is around +/- 25% from centre

To clarify, you mean 930 fuel heads, correct?

flow data this morning was apparently from a 3.0 911 SC head (0-438-100-077)

The frequency valve control range is averaged between it and the previously collected 924 head data, but should apply to all lambda units

Crazy discussion on fuel head specifics going on at the moment too

I'm a bit bored and thinking about doing something crazy.
I'm adding drive by wire to my 928 with CIS-E for Idle/Cruise/Traction control etc.

As some of you may be aware, we have been working on a proper dedicated ECU for the FrankenCIS system for the last 12 months or so and I've hit a bit of a conceptual roadblock.

It would be fairly simple to continue with the usual aftermarket ECU tuning concepts such as VE and closed loop boost control etc. but I'm feeling that is too easy and not what we really want. As part of our research into what is available we keep running into articles and research that points to better ways of doing things such as http://www.enginelabs.com/news/aetc-2013-tuning-for-boost-and-airflow-topics-open-conference/

For example an aftermarket plug and play solution for a VW 1.8t or Porsche 997 (or *cough* Ford Coyote/Chev V8) allows tuning of fuel and spark beyond what the OEM ECU allows, but does away with the integrated nature of the factory engine modelling and strategies.
Reverting to Speed Density and Alpha-N tuning with milliseconds of fuel squirt or almost VE tables just seems to be a step backwards when a modern EFI engine has an aftermarket ECU installed. So if we are updating our engines with modern controls for normal EFI or FrankenCIS, why other than for cost reasons and universal applications should we be settling for decades old tuning methodologies. It all seems to me to be a hack for convenience only.

IF we were to do an ECU firmware that gave Bosch Motronic ME7 or better levels of intelligence and specifically suited our engines, would anyone be interested, and more importantly would the concepts be acceptable to the Tuning shops and enthusiasts out there.

I have to do this for my own project anyway, so thought I'd throw it out there to you all in case I'm not the only crazy one.

Another batch of FrankenCIS blocks is on it's way through manufacturing.
Thanks and congratulations to everyone who has installed the system so far !!

Status update for anyone waiting on backorders

I'm told the blocks are going through anodising in the next couple of days, so we should have stock available for orders and shipping by Monday
