Ram Jet 502 MEFI 4 Crank Position Sensor?

[dave w]

If it has the l31 crank reluctor why cant you use an 0411? there is a van l31/4l80 file in the repository that is 12212156 o/s I believe.

The '0411 is a good option! For the moment, the plan is to keep to a minimal budget. I'm sure once the "Black Box" has things running OK, upgrading to the '0411 will likely happen.

My marine guy got back to me and here is a 502 marine engine with part numbers and prices.

And the reluctor for the crank(#40) and the cam gear CMP sensor(#39). By the cam gear it looks like it is a 1x signal, in that case the CKP sensor will use a 24x reluctor.

The CKP sensor you pictured since being used on a 4x reluctor, it will work with a Blackbox PCM.

The truck is a 1996, not good news PCM wise. I've not looked lately, is there a tuning software available for the 1996 black box?

I have TunerCat. I'm wondering if there is data logging software similar to HP Tuners or EFI Live for the 96 / 97 Black Box. I'm thinking not, but maybe there is something available now.

I'm in a no start situation with the 502, no crank shaft position sensor input. Does anyone have a part number for the Ram Jet 502 crank position sensor, with a 4x trigger wheel?

Thanks,

These ones look close.

Used 97-99 on l29 l30 l31 l35 engines.

I can check other years engine combo.
It will definitely be a oem production crank sensor. Do you know when this mefi is released first.
