looking 4 info. on omc mad efi

Yamaha had the o2 on the intake

I wonder if an o2 sensor along with computer, temp and baro sensor could work out the air density?

Funny - I never realized that. I actually bought a couple (pricey things) to use in the exhaust for an EFI project that never happened.

I was just re-reading this thread/trying to find info. On programmer as mines outta wack n not pulsing injectors so I got some values off-set in my programmer n ecm ain’t flowing injectors darn it/
apparently I’m gonna haft to talk midgets into getting they’re hands off they’re junk n reset my programmer.

The original manufacturer of MADEFI ECU components (Simple Digital Systems [SDS]) still sells and services the ECUs and programmers and they have really good customer service. Shoot them an email.

Will do/thanks guys/kinda anxious to see this thing finally go/ain’t gonna be quiet I’m sure.

Well the guys from sds were cool/but I guess fuel injection ain’t for me/I can flow injectors with 9v battery(each cyl.) n fire it runs great till burns through the primed fuel/anyway we walked through the programmer quite a bit n came to the same conclusion/unless there’s a lacerated or pinched wire in the ecm harness I’m not see’in and one that don’t communicate with the programmer it just ain’t working/so-JETTING for this beast-if I remember right I got 76-D’S for mains but with a 315 build I’m thinking need to bump them up to 80’s probably then 16 down mids n idles.

[bigbore]

Oh yea/ain’t see’in aluminum manifold air box cover bolts to or choke primmer/ain’t dug through everything yet but/neither ones out in the open-that’s for sure

[bigbore]

Found choke primmer n 3/8’s fuel line I had in there running Holley red/bypass vro but found bracket for vro and vacuume switch/levers missing outta choke primmer though/got most stuff I need to switch back to carbs but the right size jetting and the aluminum bracket air box mounts to ain’t turned up yet.
