Crank Position Sensor
Ok
Differences between BETA I and BETA II
The crank positioning sensor hole is slightly different in the way its angled...
The Sensors are swappable (physically)
BUT... will they work the same?
If so... can the new sensor work with the old ECU?
Does it still return the same values?
If it still returns the same values it should be ok...

I spoke to the guy who is probably THE expert in Beta engine setups.
He is now using a Digital CPS from the newer Betas in place of the analog CPS from the older Betas. He says that setting up the E6K as Hall Effects / falling setup does the job of cleaning up 90% of the signal. The rest is cleared from a clean ground and a good 12+ V source.
I recently blew up... Could it be since the angle is different... is the sensor is off? Could it be reading wrong?He is now using a Digital CPS from the newer Betas in place of the analog CPS from the older Betas.

The two sensors are electrically non-interchangeable on the stock wiring. If you plugged an "old" sensor into a "new" ECU (or vice versa) it would just completely fail to read OR might even damage the ECU or sensor.
However...
I know that not ALL the BETA II blocks came with the updated crank sensor, because some of the 2002 Elantras still use the passive part -- well, at least according to Webtech.
If the angle is different in the block but the sensor is electrically the same, then it's very possible that all the electronically timed systems are off by a few degrees. This would include fuel injector timing, ignition timing, misfire detection reporting, etc...
On the Haltech it would be very easy to adjust for the angle change. But on a stock ECU, saying that the angle change actually did impact the timing of the motronic wheel teeth being picked up by the sensor, there'd be no way to adjust for it.
That would suck... frown

Great...
This is probably why i blew up....
I have a 2k1 block... so im guessing i still have the old sensor
Dam... i wonder if there would be anyway to tell if its readings are off
Hmmmm
A data logger should be able to read it right?
Then again... why risk loosing about 800 dollars on a setup that might not work
****!

JAWS, check with a timing light, at idle it should be like it's specified on your emission label
and you could also plug in a obd-2 scan tool with lap top in your car, hold the rpm at a steedy speed and compare what the ECM wnats and what you read with your timing light...

Dennis has it right. Plug in the OBD2 laptop and break out the timing gun. The computer by itself will not be able to "see" the descrepancy, because it's entire timing system is relative to the position of that sensor.
Thus, the computer assumes everything is correct based on that sensor. If it's out of whack, there's no way to tell from the computer side alone.

i dont know im not sure if i want to risk blowing up again....
The next motor will be bullet proof... i dont wanna risk it
Ill think about it.... if something goes wrong, i could just always go haltech
But i dont think im at that stage of insanity yet...

I'm not entirely convinced that the crank trigger is what caused you to blow up... I'm not going to rule it out either, but there are several other things that I would diagnose before wondering about the crank trigger.
