12200411 - A Few General Questions

[mecanicman]

Sounds like the VSS may be something I need to consider-
Does the clutch switch play any role with this idle strategy as well?
Thanks!
Elm

Yes, but it is easiar to tune around in my opinion.

What role does clutch signal play? Isn't it needed for Case Relearn? Or was that Parking Brake on manuals?

If the brake switch is solely for Case Re-Learn, I'd rather just wire a toggle switch vs wiring in the Emergency Brake-
Or are their TWO brake signals (one for the foot and one for the emergency brake)?

The biggest place you would notice it is when coasting down, high vacum situation where the tires are driving the engine. Stepping on the clutch pedal changes the airflow requirements, pcm compensates. Base running airflow and throttle cracker can cover this.

For the needs of your particular build, I think the EFIConnection timing cover would be your best choice. You can use that cover with EFIConnections double row timing set that has the CMP reluctor built into it. This cover would give you what you are looking for----Double row chain, CKP sensor, CMP sensor and not affect your stock distributor.

Jeff,
Where can I see this cover/timing set?
EFIConnection's web-site leaves a bit to be desired. They seem to offer many products that aren't listed. A catalog would be ideal.
I've seen their modified Vortec cover that fits GEN I SBCs but it looks like it's simply the Vortec cover with a GEN I flange grafted on?
From my understanding, it still doesn't support a double row timing chain- If it does, they should list that detail on their web-site and they'd get a TON of sales!
I also don't see where where they offer a double row timing chain / reluctor combo?
I will be utilizing the 4x crank reluctor, which I don't think EFIConnection has re-tooled for GEN I / double timing chain applications.
Can you clarify?
Thanks!

Elm,
There will soon be a SBC / BBC distributor (small cap point style) that has both the '0411 4x crank sensor and the cam sensor. It will Not have provisions for the mechanical tachometer. The above mentioned distributor is patented! Pricing has not been determined. The first production run is scheduled in early 2014. Production runs are currently being quoted.

The setup with the 1x cam signal on the front cover isn't available yet so not much detail. The picture does show double row timing gear sprockets.

You could use the LT1 kit for the double row timing chain. The water pump drive hole would have to be plugged.
