Without proper explanation from Grimaldy, i think all of those warnings are just a matter of a bad feeling or extra precaution.
Did they really go into this matter, did they research the complete circuitry and did the measure the internals of the pedalpot?
If they did, i would be glad to learn where i made a mistake in my conclusions of course.
The two potentiometers inside the housing are simply interupting when worn. (The resistortracks wear and resistormaterial is scratched slowly from the isolating layer.)
IMPORTANT: An interupted signal does NOT cause full throttle, but NO throttle, or limp mode!
Two parallel potentiometers (after the soldering mod) that would interupt at exactly the same (worn) spot of the resistortracks (chance is 1 on a million?) wil cause NO throttle, NOT FULL THROTTLE!
Therefore, the warning above is unnescesairy, because NO throttle is exactly what is going to happen with a worn UNMODIFIED pedal potentiometer in the first place.
Please let someone tell me what the problem of the mod IS then!?!
If BOTH tracks inside a modified pot are wearing further and further, even the two parallel resistortracks will get out of range, causing CEL and LIMPMODE just as an original one, forcing you to exchange the pedalpot finally.
Things would be totally different of course, if an interupted reading would cause FULL throttle, but that is NOT the case.
In that case the warning of Grimaldy would be wise and very relevant, but i would not ever have advised to do so in the first place!
Still: Exchanging the Pedalpot would be the best thing to do, that is where i would agree with Grimaldy.
