Obscure application here. I'm doing a 3D ignition system on my 3.4 twin plug motor. I need to acquire load data for the 3D map. TPS is my first choice as its straightforward and doesn't require a rats nest of vacuum lines.

However, I'm running PMO 50mm carbs. All of the carb shaft TPS sensor kits are based on fitting Weber DCOE/IDF carbs. I know that the PMO jets and other parts are IDF based.

So my question to the collective is: Are DCOE/IDF throttle shafts the same dimensionally as the PMO ?

Thanks!
