I have been very sick (hopitalized) and have not played with cars for a time, but now i slowly started up again.
I the last few month i have run the VEMS as a measuring system in my car, and collected parts to use for injection. I had a complete intake from a 91' with injectors, fuel lines, idle valve, and pressure regulator. So now i need to fabricate some adapters to mount the intake.
I made some testing on the desktop, with all injector's and Idle valve connected, and using mstxx mspxx commands and megatune.
So far i found some issues that need to be solved before vems is controlling my car.
- The idle solenoide PWM frequency has to go down to around 100Hz, since right now vems is frying the valve.
- The temperature range has to go higher than the 101°C that it supports now. But i'm not clear about what to do with all the config parameters if i just change numbers in in the termfactor.c what/where to change. And I like to use Celcius + 100 as temp bins giving a -100 to 155 range.
- I'm still not sure about my trigger setup, so far the rpm meter's signal has seem ok, but i still consider 36-1 at crank, and thinking about how to implement the 2.trigger for fully sequential injection.
- Stil unsure about ignition. I have not had success to test the Ignition output from vems with the LED connected to +12 and IGN_xx from vems, it flickers very uneven making me questioning my trigger signal. I may have to take a timing light apart to make a test light.
