The current circuit has no adjustability... it's fixed for regular 10 percent ethanol.... But It would def be possible.

 

It would be great with adjustability as further north temperature swing allot through the seasons and the mixture incase of E85 situations.

 

if your ok with e-mailing the schematics i could try building your emulator as i would love to avoid spending $600 on a replacement sensor.

 

me too,i have a 2000 b-3000 4x4 that was my sons,hes passed now but i'm tring to get it going and do not have $650.00 for a new ffv sensor,,my email is oldgun@att.net thanks wayne

 

Just wanted to let you guys know that Toehead had sent me the schematic a week or so ago and i built the circuit on a breadboard and tried it out. It seems to work fine. I dont have a scope, so i dont know exactly what the reading was , but the engine light is out and the truck runs fine. I tried to make a permanent board, and i need some help with my soldering skills. LOL Im gonna try again.

Thanks again. Always great when people can help each other out.

Could someone also please send me the schmatics??!?

If anybody feels gracious i could go for those schematics

My E-mail is MavericX45 at Mail.com

I'd appreciate it....allot.

 

Wow, thanks for all the kind responses! I just checked this board for the first time in a long while. If anybody still needs my circuit diagram, feel free to email me at ubchenelle AT gmail.com

Thanks guys!


If any mods are interested in perhaps posting this diagram somewhere, just shoot me an email.

Thanks for the offer. I sent you an email. If you send me back a copy of the diagram, I'll host it.

 

OK, here it is folks, compliments of Toehead: Ford Flex Fuel Sensor Emulator Schematic


Thanks Brendan!

 

Guys,
Today was the last major hurdle for the circuit. It has been installed since my first post, and has faced the new england weather without problems. Today I passed the Massachusetts obdII emissions test

 

Excellent!

 

bump for the searchers

If anybody has built the thing I'd love to hear how it went.

 

I was wondering if anyone in/near central Vermont has tried to put this emulator together, because I might want to buy one as a back-up to put in my truck because I have the 3.0L Flex fuel Ranger.

Thanks
Steve

 

If you can't find anybody else, I can whip one up once I have some time. Not sure how much it will cost... it's probably about 20-25$ in parts counting the epoxy and hobby box. (I built the circuit, tested it, and put it in a hobby box. Then I filled it with epoxy to make it waterproof. )

BTW, still working
