Input variables where Inj_out is dependant of...

As my car will be running on Vapourised LPG injection my Inj_output timing will be dependant of Fuelpressure and Fueltemperature. I already have a sensor mounted that's able to collect these values.

Connect the signal to free ADC inputs - mcp3208. Check the shop text for free inputs. Apparently

When the plan is ready, we'll add to the firmware and make it possible to enable it in config.


He're a link to a forum I'm member of. The problem is also stated there: http://www.e30tech.com/forum/viewtopic.php?p=218272#218272

A few questions I have after reading your reply:

I want to run fully sequential injection and ignition with and Hall sensor as secondary trigger. The secondary Trigger is onboard and from what I understand in your reply this leaves EC18pin12 available.

From what I understand from your answer. I can use EC18pin6 as an input channel because I have an onboard MAP sensor and this input is therefore free.

software:

From what I understand you need 4 look-up tables:

-Fuel_temp : Vsens_out

-Fuel_pressure : Vsens_out

-Fuel_temp : Desity

-Fuel_pressure : Density

I can configure these tables in excel if you want. The values will be between: 0.25V and 4.85V.

For the Fuel_pressure Vsens_out can also be configured with a code being: Vout=(c1*Pabs+C0)*Us. Or must this be in a table?
