Speed six throttle switches

[philburch]

Hi all.has anyone fitted the upgraded throttle switches that Motaclan sell if so do you think the car performs better . Don't mind spending the money if it makes a difference

If you mean the TP sensors then it is more a case that one of them has been discontinued and only NOS (if you can find them) or used versions are the option to repair. So the 'upgrade' is the only option if you have a failed sensor.

Had a problem with the car six months ago replaced the grey sensor all was well but the problem has returned so i thinking it is the sensor again.going in for a service soon so i will see what they think .

As they have both the original TPS in stock ( the black one I think is the obsolete one which I assume they have had remanufactured) then there is the option to replace with 'factory stock'.

That said, it would be sensible to track down why the same fault has returned and, assuming there is a fault other than a dodgy sensor, fix it. No point spending any money if the new sensor is going to fail again in a short time.

If it is a faulty sensor hopefully be replaced under warranty but is it going to be an ongoing problem because of there poor quality.My thinking is if the upgraded parts improve the cars running that is £160.(for two sensors ) towards the £500 for the better quality ones that will work out cheaper in the long run,will get the garage to check it out as you say could be something else going on

The comments in this topic https://www.pistonheads.com/gassing/topic.asp?h=0&... also point towards the quality of replacement blue throttle potentiometers.
