I want to check the base setting of the TPS on my cosworth 4x4 L8 but dont know which value is best to use.

Here on the board I read that the base setting should be 70 Ohms, but in the Ford manual it says 40 Ohms.

The reason I ask is that when pulling away with my car it feels like its short of fuel when setting the CO at the required 2.7%. When turning it up to about 8% it pulls nicely away.

I think a wrong base adjustment can also cause this.

Its on greens, 3 bar map sensor and chip. Hope someone can explain it to me.
