Gena Posted February 13, 2008 Share Posted February 13, 2008 Hello, I am considering purchasing an Apexi Neo piggy back computer to control the air fuel ratio. I noticed my MPG rate has decreased significantly in the past three weeks that I have owned it. Has anyone installed a piggy back on the GS before? How were the results?

SKperformance Posted February 14, 2008 Share Posted February 14, 2008 It has been poorly tuned and it keeping power settings without being set for WOT. Get a shop to run it on a dyno for proper alignment. Quote Link to comment Share on other sites More sharing options...
fodogsfo Posted July 29, 2008 Share Posted July 29, 2008 It has been poorly tuned and it keeping power settings without being set for WOT. Get a shop to run it on a dyno for proper alignment. I think you'd be diggin yourself into a deeper hole with Apex'i's AF controller ...I hardly trust the company's R&D dept. to make something suitible for a GS400...they specialize in Honda's don't they? I believe their controller is not suited well for vvt-i either....only vtech. Quote Link to comment Share on other sites More sharing options...
SKperformance Posted July 29, 2008 Share Posted July 29, 2008 The neo is not a engine management system it is a piggy back controller . It only intercepts data streams from the MAP and throttle. It has nothing to do with vvti vtec Honda/ toyota or the rest of it. It works the same on any car , it needs to be programmed to be Abel to work. Apex-i doesn't specialise in any car. Your comments sound very illogical and do not seem to represent facts fodogsfo ? Quote Link to comment Share on other sites More sharing options...

VERY high standards........buddy of mine has their controller in his supra and works FLAWLESSLY on the vvt-i! i used to have their ball bearing turbo kit for my sohc d16z6 it was impeccable! they don't make parts for just Honda's they do all car's and are a well respected shop in Japan as well as America! brian Quote Link to comment Share on other sites More sharing options...
