Hello everyone,

If tuned properly can the L31 Vortec 350 fuel injection opperate without a crank position sensor & reluctor wheel behind the timing cover?

Essentially running the fuel injection off of the distributor trigger/cam position like the L98 TPI or aftermarket fuel injection set ups.

The computer is LS based running a 2002 G-Van 5.7L tune, I have HPTuners.

Can the comp tune even be written to delete crank position sensor?!

I know the LT1 guys are removing/deleting the CKP to run double rollers. I'm just not sure if the L31 uses the CKP only for missfire detection or to time injectors.


Thanks guys

No. The PCM needs the CKP sensor data to fire the ignition.

I can confirm that. When I had a crankshaft break between the timing gear and the balancer the reluctor got crooked and took out the CKP sensor. The engine would not run without it - everything else was fine.
