I have a 408 with TFs 225, FAST 92, Tick cam 239X253,114 LS, It was running and I swapped to a Holley Dominator, and used the LS-1- 4l60E drive by cable tune! That's when things went bad for me! Gone threw 2 sets of plugs, PIG Rich, I double check my wiring Its OK and it goes to the batt. Also checked my parameters, any help on what to do next would be appreciated, THANKS! OH Any body in north Louisiana have one of these ECMs Thanks Again.

Thats just a start up tune basically, it could easily be no where close for your setup. Did you make changes to that base file? I can build you a tune thats alot closer and get you going in the right direction if you would like. Call or email me if you want more details and pricing. Email me what you have and I'll look at it for free, be sure to include the whole tune. Email is in sig below.

Do you have the self-tune enabled? Can you confirm that your power and ground wires for the Dominator are both run to the battery?

Yes sir, all power and grounds wires going to Batt. Thanks

I would load the ls2 fuel and spark map to your tune. This should get it up and running and the closed loop can take over from there.

Call Holley tech also they should be able to walk you thru some settings.

The base tunes have been close enough on the 4 systems I have installed.

Thanks for the tip, I will try the LS-2 tune tomorrow! AM I used the LS-1 tune because I have the 4l-65E with cable TB, Thanks again

Wouldn't the LS2 be drive by wire and the wrong reluctor signal??

I have a similar setup, and am in the same boat. I transfer the fuel learn tables over to the base map, but it still runs so-so and pig rich...

I think gto ls2 reluctor is 24x

That is a stand up thing right there!

To the op, do you have the wideband o2 sensor hooked up?

Please note that this thread started nearly a year ago and the OP sadly never posted an option.

ILLINTENT: Please start a new thread if you like.

I will leave the thread open in case the OP would like to post an update, but lets otherwise consider it closed so that members don't waste time responding to a dead thread.

I should have let everybody know, The problem was a miss fire due to not using shielded wire on the cam sensor ext, Car runs great now, I should have read ALL the small print, Thanks to everybody for the help.
