Basically it's a module that allow the driver to adjust what's called... the "Throttle-Curve"

It alters the values between the actual-throttle-position and the ECU-throttle-position.

Therefore, when the gas pedal is 50% depress and ECU might thought it's at 60% or 70%.

By reading its diagram, the adjustment is most effective through the mid-range.

I am not sure how much it can improve/correct the problem that Mr.kenchan is experience since he is complaining the initial throttle-response.

Which...the pedalbox has the minimum effect on that position.

My opinion, this module is more suitable for track use since the driver can:

1) Adjust the throttle-response according to different track lay-out.

2) weather condition (dry/high traction surface more responsive vs wet/low traction less responsive)

On top of that, I am wondering the adjustment will lose its "effectiveness", not from the device itself, but the driver itself will get used to responsiveness of the throttle.

alcheng's conclusion: Save the $499.

CAD$0.02

Great post!

Usually the retailer will fill the whole big box with tons of foam and bubble wraps and stuffs like that, I am pretty sure the HU is in good shape...

mr. alcheng- yah, i left work early today

and checked out my HU... the outer shipping carton and the gift box was damaged but the foam inside was still intact and from wat i could see, everything looked fine. yep, ordered yesterday, delivered today.

Thoughts? Comments?

hummmm... i dont have a lurch, the throttle response is slow and wanted to get rid of that.

did you replace your helper spring yet? that helps quite a bit on the take-off. i think LMB still sells them?

thanks, mr.alcheng. yah, it's really similar to how i compared it to my software piano latency. the initial latency is still there, how the throttle input quickly ramps up is just different. and so yah, not buying it.
