Any Electronic Gurus In Here?

Hey guys,

I have changed my throttle body and i need to set up a tps for it.

I have an rb20 engine and have changed my throttle body to an xf one

I have noticed that the xf tps ranges from 500 ohms to 4600 omhs, but the rb20 tps ranges from 2000 ohms to 10 000 ohms.

Is there any way that i can modify the out put of the xf tps to turn it into that range?

Maybe using resistors or something?

Thanks for any help

I dont think using resistors will fix that can you use the rb20 tps at all

[RB SANDY]

also what computer you using you might be able to use the xf one on a aftermarket ecu

Nah no aftermarket computer

I don't have the rb20 tps any more, it got sent out in the rubbish thanks to my brother

I have put power through the tps.

The idle voltage is 1.85 V and the fully open voltage is around 10 V

Is there anyway of changing it at all?

Like something where you can set the starting resistance at .5 V and set the end at 4V and it controls the in between from this information?

Thanks for any help

Not real sure on nissan computer signals but I think the computer will be monitoring the voltages and not the resistance.

Sounds like Xf TPS = 0 - 10 volt and Nissan = 0 - 5 Volt absolute readings.

Both are industry standard signals and you can get simple convertors for the task of scaling these voltages, even a 0 - 5V convertor will easily be adjusted to give you 0 - 4V if that's what you really need...

If your even a little handy with a soldering Iron I think you can buy a build it yourself kit from Jaycar or similar prolly from around $30...

Hope this helps.
