Can anyone tell me what the side effects of fitting a delimiter and speedo converter to my jap import tt auto.

Will it adversely affect performance due to the speed information being different and affecting gear selection?

Any other info is greatley appreciated.

Anyone know if andyP's chips change the kph to mph on these or not?

Thanks

A chip will only remove the speed limiter in the ECU. If you have changed your speedo to a UK model and changed the chip then you no longer need the speedo converter box.

my experience with one of these is that it makes the autobox shift points all messed up, and the steering excessively light. I never really found out if they all do that or if mine is faulty or something. Would like to find out though.

my jap NA auto worked fine with a speed converter. The only thing that if may adversly affect is the speed related power steering. Theory is - the converter takes 3 pulses(km) and turns them to 2 pulses (mph) so if the speed sensitive power steering is only getting 2 pulses instead of three it thinks that you are travelling slower and therefore offers more assistance.

 

I'm now driving a manual NA with a speed converter and it feels just the same as the auto re weight of steering - so maybe the auto box takes its information pulses from somewhere in front of the convertor. Try cleaning the speed sensors on the rear driveshafts...

 

...there's logic in there somewhere...

 

Good luck
