Hi guys, looking for help. I have LQ4 with LS3 heads, I would like to install a supercharger but not sure what is needed to make it work, LQ4 has 24 relucter wheel while the LS3 supercharger will require 58. Car currently set up with LS1 pcm.
IS there adapter wiring harnesses or aftermarket ecu that should be used, this is outside of my knowledge of these engines.

 

The supercharger itself shouldn't be able to tell the difference. The tuner that comes with the kit is likely set up for the 58x signal. You will need a custom tune anyway.

 

its been suggested to use a Haltech 1000 ecu, value close to $2000. seems like alot of doe. Come on guys , whats the best way to do this conversion, it would take more than just a retune.

your confusing what you need. as long as the supercharger kit matches the alignment of the front accessories, it could care less what you are using to control the engine. I am running a 2004 GTO supercharger on a 2000 camaro ls1 in my 67. (the gto and ls1 camaro use the same FEAD -front end acc drive) The only reason you would care about the ECM, would be a pre packaged ture, and you should forget the canned tune an get a real one. The only other concern, would be if the injectors included with the s/c kit used the same conector as your harness, if not, adapters are avilble or just get a set of plugs and cut solder them to your harness, no big deal.

 

You will probably need a 2 BAR map if its not in the kit already.
