Whipple 132mm guys please

[Burkey]

I’m interested to understand the settings on the 132mm TB.
Mine simply cannot be adjusted to the specs that Whipple stipulate.

I can either get the static numbers to fall into spec, giving a “fully closed” reading of 0.327v (that’s the lowest possible value no matter how you adjust it)
OR
If I set the fully closed at anywhere inside the spec, it falls outside on the static setting.

The issue I’m having is that the throttle feels very disconnected from actual pedal input, taking the TB quite some time (about 0.7sec) to reach 85% when transitioning from cruise to WOT

I’m definitely NOT adjusting it wrong. It’s simply can’t be made to line up with the given specs.

Can the voltages affect the speed of the TB reaction?
I’m trying to build an idea of how it actually works.
I opted to keep the correct voltages when static, ignoring the fully shut voltage, given that the TB will never actually reach that position in the real world.

I would reach out to Whipple and see if they can help. I've heard them even do it for customers and send it out to them.

I had to adjust mine. They are extremely sensitive. Good luck lol

I wish that was an option. Being in Australia kind of rules it out.

I would give them a call anyway I'm sure they will try and help.

Yup, VERY sensitive. I spent hours getting it “just right” but it’s still wrong in one way or another.

Did you try driving yours whilst out of spec?

Yea that was how I found out it was out of spec. Kept having idle issues while data logging. Car drove good other than the idle. Sent a video of it to Lund and they sent me instructions on how to adjust it. Took me a good hour of pulling it off, moving the magnet slightly and then reinstalling. Testing. Repeat. I didn’t get it perfect but I got it as close as I could

I measured max closed position. Had my dad in the car reading the Ngauge while I closed the TB

Cool. As long as it doesn’t have to be “perfect” I’ll be giggling.
If the TB closed about 0.1 degrees less when pushed shut, I’d be dead-on.

So...you adjusted it on the car? Never pulled the throttlebody from the blower???

No need to remove it.

No need to remove it.

Thanks [MENTION=21513]Burkey[/MENTION]

You have enogh slack to have the harness plugged in so you can read open/closed TPS voltages then???

No need to unbolt the TB at all.
Just remove the air tube, place hand in TB, push blade backward to full closed.
Set Ngauge sleep time to max.
Place Ngauge in engine bay.
Commence cursing for the next hour or so as you proceed to miss the target voltages by increments that are immeasurable...:headbonk:

Whipple have since confirmed that they want the fully closed voltage between 0.40 - 0.45
They really don’t care what the other readings are. Not sure why they put them there.

For those playing at home:
The only reason I’m adjusting this is due to the TB not following the pedal accurately.
There are NO CODES.
Stabbing the pedal (WOT) sees the TB taking 0.7 seconds to catch up (85%)
Try and drive a car sideways with a throttle delay like that....it ain’t happening.

The tuner believes it to be caused by the voltages.
I’m not convinced.

I think it’s far more likely the result of an exaggerated “tip in” time and a jammed up torque table, but I’m NOT a tuner by any measure.
Will report back with findings.
