TorqueHead vs Opti

Do not understand NHRA’s reasoning but that is the rule.

It is a nice bolt on system and ECU easy to tune.
Our B-Body clubs like them.
Especially the Boosted crowd.
Agree single Coil is enough.

Until this weekend was fine using TunerCat for ODB1 PCM.
Been a 15 year labor of love learning most of the Files.
Excellent ECU. Opti is reliable.
Just discovered it’s limits.

Thanks for the help.

Dan,

With all due respect, in lieu of trying to reinvent the wheel. Listen to the guys that are running the Opti-Spark system. On the long run, it will be more reliable, better performance and cost effective.

I am !!!!!!!!!!!!!!!!!!!!!!!!!!!
Having a fight with Pat Cvengros over this RIGHT NOW !

Dan
Where did you get that information from?
I disagree since it clearly has a distributor with a single coil.

My response !!!!!
Found out mine is considered a Distributorless System
So a Crank Trigger is fine..

Previous Conversation;
No, crank trigger ignition systems are only permitted on distributorless ignition systems.
If you switched to Super Stock you could run a crank trigger with the Opti spark distributor.

Pat thinks the Opti s not a Distributorless system !
So I am confused.

Needs some help here !!

Follow up EMAIL from Pat !!

Dan,

Unless you have documentation from Chevrolet stating it is a distributorless system it’s not; so a crank trigger would not be legal.

1. Distributor: a device in a gasoline engine for passing electric current to each spark plug in turn.
Pretty clear to me you don’t have a distributorless system.


========================
SO I am confused

Just sent Pat KRATLIF's response.
Pat's response is below.

Dan
Thanks for the heads up, we will have to look this weekend at Pomona.
As I mentioned previously, unless you have documentation from Chevrolet stating it is a distributorless system it is not.

Then sent GUMPS response...

Pat Responded
You can believe who ever you want,
I’ve answered your question based on how NHRA officials interpret the rulebook.

Crank triggers are not a legal option for the Opti Spark.

So what you are saying is that you just rocked a boat that was on calm seas....

If enforced under this interpretation, this would park pretty much every LT car running Stock Eliminator! I'm pretty sure that Holley doesn't have a harness. I don't know about the other systems.

Keep being AWSOME Dan!!

Hard to put the worms back in the can after it's opened. Good going Dan !

Not even close Dan. all you have done is start a conversation that doesn't need to be had.
Where does the OEM optispark pick up it's signal? From the crankshaft? Then it's a "crank trigger" system.
IMHO, (and I'll probably catch some heat for this) any OEM ignition system that uses a crank sensor and a cam sensor to sort out the timing events should be able to use an aftermarket type crank trigger system.

[Drunken DragPak]

A crank trigger is nothing more than a crank sensor, the LT1 came factory with a crank sensor and nowhere in the rulebook says you cant use aftermarket sensors.

Billy and DDP;
Then you better have that conversation with Pat Cvengros!
What we say does not count if he believes otherwise.

These are not our rules !
Pat is the arbiter not us !
Read the exchange….

I ran into the limits of the OBD1 PCM.
Sought advice from people more experienced than I.
The 8.3 rule was confusing comparing available products out there.
So contacted a Technical Director.

The feedback from CR is in conflict with what Pat said.
So before proceeding over the rulings cliff.
I want clarification !
Wouldn’t you?
