This Thread is started to to bring together the overall engine management system knowledge and , options for after market ecu ,injector ignition off the shelf or custom system over lays.

I started with this one from Stan which I hope every here enjoys to
see again
Patent number: 5293857
attached

Note
Particular interest is the gas mixing chamber and ambient air
in to gas processor with gate (throttle body which is connected to ecu for
accelerator position) and figure 3

Several companies can offer pcs, omnitek is great one.

Other patents which help the common knowledge of ecm operation
with hydrogen injections on vehicles

OK I HAVE A SMALL CACHE OF LPG GUYS STARTING

I WILL POINT THEM TO THIS THREAD

PLEASE DO SAME for poeple form installer industry

SO THEY DON"T MIX INFO for installing  experiences and ideas

WITH PURE REBUILD INFORMATION IN OTHER THREAD LIKE INJECTOR ETC  

HERE CAN BE MAP< ECU SOLENOID , bypass reprogramming  
and AND TECH KNOW HOW FROM LPG ?CNG INSTALLERS ETC

Look forward to Opening it up  for

development from this industry experiences to date alot has happen since 1985

Some kits on the market are amazingly simply  to adjust in software and config.
not to mention well made and cost effective.

DANIEL

 

FYI for comparing and adapting with YOUR current LPG KNowledge etc

re post as relevant from tony another forum

Ok after thinking and looking at the locations of VEE and thinking about it from a cars electronics point of view, I've come up with what VEE is. VEE is a 12v supply voltage. If you know anything about a cars electronics, its the ignition switch. On a cars ignition switch you have ACC and then the "Start" position. ACC will turn on the circuit and all other electronic accessories. When the ignition is in the "Start" position this will energize the ignition coil and engage the starter. As far as VEE, when the cars ignition is in the "Start" position, this will turn on the VEE locations allowing the circuit to start producing hydrogen. This also acts as a safety feature so that for example is you have your cars ignition switched to ACC to listen to your radio, you want be producing hydrogen. Pretty simple explanation huh?  


I think
Vdd 5v
Vcc 12v or 5v ?
Vee 12v

Yea VDD = 5V,  VCC & VEE = 12v

Thanks - this helps clarify the voltage sources for the circuits greatly!

NOw the guys above used defaults and technics which are standard
they just basically reprogrammed using simialr tchnics and software which is
standard already.

What is important is the thinking here and how is is possible now to do this.

INfo you need to learn.

Fuel injectors  
adapt LPG GUys

now a O2 sensor, small micro controller ( Arduino) and short program and you can control the air to fuel ratio.

New
Version

of ECU and EMS

I have put together the fitting and plumbing
I have a manufacture for quenching tube it is a special mould process
from ptfe, so I am trying to match he solenoids to tube size at this time
to trail that part of it

HI I am Making Massive Info Advances

I will start to post injection and Ecu training Advances
which are now available on my site

11 cell
vic
and Queching tube are key parts to getting Stan
 tech for hydrogen on demand over the line!!!

please help complete it and get it into a file that can be cad machined or
reproduced asap.

rest will happen very fast as I start to post

See attached for sensor emulation.

Dear Member I have added alot of ECu info o my Website.

I have also added this video ref here suggest you watch it carefully and look the the educational info on my site in ecu ,aircraft and efi kit sections.

it simplifies the ems , to be off the 2013  shelf fuel injection
