Any Gen 3 Hemi experience....
 

Anybody done a late model Hemi in a project?
Curious who's harness you used and why. Any issues you might have run into?


Jeff-

We have done a few of these projects if you want to give me a call

HotwireAuto is about the only company i've found that has been doing it a while.

I used Street & Performance in Arkansas for two LS harnesses. I know they do HEMI harnesses also. They were very helpful both times every step of the way. Hope it helps you out.

Thanks Mike! Waiting for my day off, otherwise I'll catch a call the second you say hello....

Thanks Dale, that is one of the companies I'm looking at along with BPE http://www.bpeusa.com/G3Electronics.asp

The company Dale referenced is also in the same small town in Arkansas... probably a co-ink-a-dink.

We've done quite a few. We used to make our own harness by pairing down the stocker, but as of this year, we simply use the Holley EFI computer and harness. I like the Holley setup as you can always upgrade your engine with just a few key strokes.

Bouchillon (BPE) uses Hotwire Auto. They might get you a better deal than going direct though! Randy over at BPE is a great guy.

Very good info Dale. Price is definitely important but Hotwire is a lot closer to me if I got into some trouble with my first Hemi transplant.

All the Mopar shops are using Hotwire harnesses. I'm working with Affordable Fuel Injection in Michigan to build harnesses that work with HP tuners and the stock PCM.

Holley now offers plug-n-play harness and ECU kits for GenIII hemies.

Thanks !!

Doing a Gen 3 Hemi using Holley's ECU and Harness. they'r enice for plug and play, require a few add-ons such as coil drivers but well worth the control. No VVT control native to the system yet but there are work arounds.

Thanks for the info!
The Holley stuff looked like a bargain at first glance but once you put together all the components needed and the ecu, it's pretty pricey (or did I miss something?). Definitely the best choice if you plan to do a lot of high hp mods to the engine. I would like to use the VVT and only plan to add headers. I'm leaning toward using the factory stuff as much as possible.

The factory stuff definitely has it's place. I typically deal with power adder and conversions which is where the Holley tends to be a bit more user friendly. A Diablosport tuner can open up a lot of control and tuning options if you decide on the factory stuff and would like to do some tweaking.

Thanks again Dennis! I recently saw the Diablosport guys on one of those car shows tuning a hemi. Its good to know that more companies are working with these Gen IIIs.
