FG Throttle Body on a BA/BF

[mondc95ba]

Before I go searching through I/O Diagrams for the FG/BF/BA Throttle Body and Part information has anyone converted a FG Throttle Body to work on a BA/BF ECU/PCM?

If so, can you post up a how-to and what is required additionally software side to calibrate for voltage ranges (if they change), stepper motor PWN changes, etc.

I've been told you can simply swap them. Though I've never done the swap and have never compared the two, so the information I was given might be wrong.

I bought a wiring adapter, and was going to install one one mine.... but never got around to it. so this is proberly not helpful

Made my own harness for next to nothing and can confirm it works.

Now to make the adapter plate with countersunk screws to have it reach the same thickness as a BA\BF throttle body anyway.🤦‍♂️

Yes can confirm the adaptor cable you can buy will work I'm running the FG Plenum and FG throttle body on a SY2 Territory adaptor cable plugs straight in and works no issues at all

did you change any settings? I'm about to put a fg throttle one mine and comparing things that seem vastly different are :

AUF0077 - Convert pedal position to des ETC angle

AUF0083 Desired throttle angle as per pedal position

AUF0084 b as above

 

couple of smaller things like throttle count wide open etc are marginally different

No changes here mate, plug and play really.
I haven't looked at these settings myself, but if the table axis are the same i'd assume you'd just have to copy the FG tables to the BA if you want the "feel" of an FG throttle.

Stepper motors are controlled very similarly, just the nature of how snappy and responsive they feel is different between models.

Happy to be corrected if I am wrong on this.

for notice,

I have a fg TB and FG intake on a bf motor.. I noticed if I let it idle it would start hunting (rev up and down) but i knew the alt was not charging so figured it might be related.

Last night was i able to get it to have some temp, iv started it numerous times cold no problem. Warm starts it would stall instantly. I noticed it was opening TB for start, then basically closing it.. commanding less than 1 percent blade angle. When holding the throttle down you could make it idle and the blade would be somewhere in the high 2, sometimes 3 degree mark.

AUF0082 - open loop feed forward throttle angle predictions. This table is vastly different BF/FG and with the FG setting the car started and idled spot on.

Ive just now noticed AUF1249 pressure drop table might also be worth having FG settings from.

 

so far most of the petal/throttle angle settings altho they look different, or are setup differently have verry close to same reactions. so just changing a b-series tb for a fg one may infact just work. perhaps the airmas tables change due to the intake manifold change.
