Is it possible to make a fuel controller?
Jesus, are you dense? You have no right to speak to any of us until you have shown us boobies.

Just route a huge pipe pre-turbine into your intake manifold. The EGR affect will make the car so effectively rich it'll be free tuning. If you blow it up tho remember. Your pipe wasn't big enough! Rebuild the engine & try again with a bigger pipe.

When I did it, before there was boost code, I did it right. I reregulated MAP sensor input to 3.1 volts and rescaled fuel and ignition mappings to reflect the rescaled MAP signal, which allowed me to correct the ludicrous ignition advance found in AFC and other fuckstick hackjob attempts at blowing up engines due to ignorance, which people think is okay because instead of ------- thinking about what is going on for one microsecond they can just say "but I didn't know" and that excuses their ------- around for hours on end hunting parts assembling circuit installing it and calibration and fiddle ------- around to no avail because thirty seconds of applied intellect is too strenuous.
My MAPhack required a chip burner to set fuel and ignition mappings where they needed to be, and if you have that in this day and age there is no excuse not to run boost code and throw the Radio Shack circuit in the garbage.
There are writeups, by me, on both MAPhack and AFC ignition advance on pgmfi.org and HT respectively - there is even a subforum for the MAPhack. Go use a search function and learn something covered in great detail five years ago, instead of wasting our time with this.
PS - you n00bs wouldn't get flamed if you didn't post this ---- in GD when it belongs in the engine management forum.

I was thinking of doing a simple open loop fuel injector controller, But that though was cut short when you reminded me about the old hacks and ignition problems. My idea above was just trashed from that reminder.
Lets say I wanted to make a plug and play for obd2 car piggy back for fuel only. One that you could hook directly up to the harness and then it would piggy back on the ecu with usb software to tune it. But its not worth it unless the ignition can be retarded otherwise people with boost dont have any use for it.
I'm rambling on, too much red bull for me. I'm guessing you dont have any messanger that I can BS with you on?
