Hey, been thinking about this for a while and i cant realy do a manual conversion atm so i need to find a way to make my car have a tps not on the carby, i played with a few tps's yesterday and yeah, got the following readings
THROTTLE TM/TN TP
0% 1.8 Ohms 1.6 Ohms
50% 3.3 Ohms 3.7 Ohms
100% 4.7 Ohms 6.4 Ohms

so i was thinking using the following resistors, make my own tps in a case similar to an afx controller that i could mount under the accelerator in the car to give a reading in around 6 stages 0, 10, 25, 50, 75, 100
0 =1.5
10 =2
25 =2.5
50 =3
75 =4
100 =7 or something similar to that,
as soon as i get my alternator ill be trying this out, so anyone wanting an auto + webber may have a cheap soloution to the tps problem soon
