[Diy_efi] Microcontroller based Auto Related Projects

Fri Nov 16 01:35:02 UTC 2012

no no no...I'm not into that sort of crap either. In fact I don't even like
when someone talks to me about the color of paint on their cars for eg.
I've been on the list on and off never posted before reading and seeing
what comes up. But lately have got a lot of time due to no projects going
on at work. I'm a mobile comms engineer btw. I've done some 1/4  mile
racing with my (now sold) 1988 toyota corsa (2 door pop-up lights type)
1.5l turbo/IC car. Did a lot of mechanical mods and basic EFI 'fool' mods
to increase boost etc. Did win a couple of races, lost most others! lol

I've found the idea of building a single injector controller a good place
to start especially when what I do feels like a walk in the park too easy
is RF optimization, lot of protocols to study though in mobile comms. So I
thought what better way to use my time now that racing is off too.

Once I grasp some injector control theory, I'll make a flow chart. I'm not
concentrating on any thing else at the moment.

Escorts are great cars among 240z and chargers that I like very much. But
never had the pleasure....

Anyways, I was reading and simply ask the question never thought of any
thing else.

Regards.
