[HOWTO: Full independent VCT cam control in BA 6 cyl]

I got the f6 catch code from a forum in here a while ago, and it’s loaded onto the laptop and it’s only got 5 gears in the gear scaler as well. Is there any reason why it doesn’t show the 6th gear or is there another catch code 

My factory t56 ba mk2 also only has 5 gears defined but compared to a 5 speed manual strategy the 5th gear min/max was a bit bigger so cruise control thinks gear 5/6 is just in gear 5

Not sure if you previously emailed us about this but I'll answer here anyway.

Basically you need frequency counter -> analog output voltage converter such as the innovate or zeitronix kit. You then need to step the voltage down to suit the analog input using a voltage divider. BF is 0.1-1.66v FG Mk2 (maybe some late Mk1s as well) are ~0-3.8v

You can't just average the frequency output with analog electronics as the sensor varies the frequency based on fuel temperature, then varies the pulse width based on ethanol %. Unless your fuel was a constant temperature it would not provide reliable results.

edit: Here are the specs of the sensor

50 Hertz indicates 0% ethanol, and
150 Hertz indicates 100% ethanol.
The pulse width indicates the fuel temperature. The normal pulse width is between 1 and 5 milliseconds:
1 millisecond indicates -40°C (-40°F), and
5 milliseconds indicates 125°C (257°F).

Hi,

What voltage divider would be used for a BA to use with the boost sensor input?

 

Thanks

Hey @Roland@pcmtec, I’m wanting to get a wideband o2 gauge for my xr6t but want to be able to datalog it too. Would you happen to have any preferences on what one to get?

Thanks.
