Sorry for the long delay, but here is an updated version with the latest information clarifying the Trailblazer ECM's that ScarabEpic22 has shared with us. The P12's were always 7x / 1x, the later V8's were E67's.
No worries... thanks for the update :cheers:
Not sure if this is still being updated, but just in case.
Under Vortec V6/V8 the 1996-2000 7.4/454 is referred to as the L19, when in fact it should be rpo L29, it uses the blackbox Vortec PCM 4x crank reluctor and 1x CMP sensor.
There is also an engine which uses the 16232148 and 16238212 LS1 PCM's. Using OS's 9354781T, 9369651T and 9384681T.
Here are 2 L21 equipped VIN's
1GDL7H1D0XJ514472
1GBMP37B2W3311219
The engine was used in 1998-2001 P30 vans, Kodiac/Workhorse
And use these specific parts Reluctor -12552480 crank sensor - 10456248. The reluctor is a 24x reluctor which actually fits under the front timing cover.
The L21 is an L29 with different cylinder head part numbers, CNP(Coil Near Plug) ignition and ETC(Electronic Throttle Control-ETC=DBW=Drive By Wire) whereas teh standard L29 Vortec 454 has cable throttle or DBC(Drive By Cable) and a single coil using a distributer. It was the 1st Chev BBC to get ETC and CNP. Instead of the distributer being used to give spark to each of 8 cylinders, the distributer is used to drive the oil pump and as a source for the 1x CMP signal. This engine is electronically an overgrown LS1. Its reluctor if sized for a smallblock Chev crank snout can be used as a basis for GEN 1/GEN 1E SBC CNP/ETC just as EFIConnections 24x reluctor does. Just need a 1996-2000 Vortec L31 350 front timing cover and the L21 CKP sensor.
Thread with some pics and some GM illustrations.
