Van Aaken Fuel Computer Manual TFC1

[TurboCinqy1250]

Hello,

I'm New Here. I'm from holland.

I have a Question about a Van Aaken TFC1 Fuel
computer.

I have a Fiat Cinquecento with turbo (at the moment still busy with an engine conversion)
I did fount the unint for my extra injector.

When i'm done with this conversion I Need to Adjust this unit but I dont have a manual of this.

Van Aaken doesn't have it either.

Can someone help me?

There ya go... http://www.aquamist.co.uk/cp/mf2manual.zip it's for the aquamist system but it uses the MF2 to drive the injector, it's the same device you have for fuelling

*takes a bow*

Rich... Isnt the TFC1 slightly different to the MF2?

 

[MrDerv]

Dunno, it looks identical

I't's not 100% the same.

Mine has a build in Map Sensor with a line to my Vacuum/boost system (inlet Manifold)

 

[MrDerv]

oh well, the MF2 is what Vanaaken use, thought it might be of help

Now I know wich side (clockwise) to turn the potentiometers for more fueling at RPM

I wil take a new picture of it instead of this ones. So you can read the txt on the print.

Oke I Did it True A Magnifying glass

Nobody more info?

Function of: Threshold, Span and Cal (Calibrate)

No idea at all Im afraid, but the numbers above the RED leds would imply to me that theyre part of a tachometer circuit

Have a read of the MF2 manual Brickfoot posted up - seems like it's very similar, should give you a few pointers even if it's not identical.

Re: Van Aaken Fuel Computer TFC1 Adjust

What is the meaning of Span on this module?

And the old one sucks. There are to many problem area's.

I'm Busy with adjusting my fuel injection at boost but it won't work. Or my Air fuel ratio is to high or much to low or normaly but is slowly falling down till it's goes to another Rev. level. It's bumping like Hell.

Maybe i'm thinking to buy a fully piggy back fuel computer or Apexi S-AFR fuel computer.
