ye iv got 5volts across the tps and wired the output to the safc, thank for the info, id be lost without it!!

Which plug did you use. There's 2 plugs on the s13 TPS, one is a variable type and the other is an on/off type?

i used the variable one its on a flexable wire coming out of the sensor all wired in now need to sort the injectors out and an s13 clutch as mine has started to slip its only done 20k.

then off to someone like DP motorsports or rc devlopments for a mapping session
