oem wiring and pcm or holley set up?

[71maroesteban]

Okay so I have the original harness that came with my vortec l92 should I rework the harness and use the original pcm or go with the holley kit that includes the wiring and pcm and from what I understand a lot easier to tune by yourself? Any input is great thanks

I have the holley hp. It's pretty nice setup. The tuning I am still learning, It gives you base tunes and the only thing that is somewhat self tuning is the fuel map table.

If you are new to tuning the Holley is much easier than the factory pwm. Lmk if you have any questions regarding the Holley Efi systems

I looked at Holley myself, but my desire to stay with DBW made it unattractive. The HP system doesn't support DBW so the kit won't work and the Dominator setup is much more expensive.

I decided to stay with the OEM ECM which I had and get a custom harness built. I'll buy HPTuners later on and still be way ahead in my opinion.

Kerry really? Looking over the overview on the website it doesn't say that on the ls3 harness I'd like to keep my dbw but if it's not supported than that's a deal breaker

The HP does not have the capability to control DBW throttle bodies, or transmission control. It's less than $800 to upgrade to the dominator ecu.
