I tried searching for this and didnt see anything directly answering my question, so I apologize if i missed something (it may have been buried in all the other throttle body threads).

I have a 2005 350z w/APS TT, built motor and Haltech EMS. The Haltech was installed and tuned years ago by a tuner I lost contact with, so idk the exact system. The car has run great for years with me doing normal routine maintenance, but lately I've been having some rough/low idle issues and want to clean my throttle body.

Here is my question: If i clean my throttle body (dont worry, ill disconnect the battery first), do i do the normal reset/relearn procedures even though I have a Haltech EMS?

 

Yeah, the standard procedure - unless your Haltech is the standalone model, which if it was purchase and installed a while back than it's the piggyback.

I'm not saying that you're TB isnt the root of your problem but you may want to get back in the shop and get a re-tune.

 

Thanks for the quick response! If it did happen to be the standalone one, would the standard procedure hurt anything? Or would it just not be successful?

 

I don't know enough about the standalone but I'd think the Haltech would override the relearn...
