Th3Franz Posted July 13, 2012 Share Posted July 13, 2012 So I wanted to post my plans to run Speed Density on the stock ECU using NSFW's patch. I have an Omni 4 BAR MAP sensor on the way along with a "fast responding" IAT sensor that I will wire into the MAF harness. I will make it plug and play so that if I want to run the stock IAT sensor I can just switch the plugs. I have an aluminum bung that will be tig welded onto the FMIC charge pipe to place the new IAT just before the throttle body. Is anyone else now running the speed density patch for Open Source (or Cobb for that matter)? I know some STI folks have been. I have been reading up on the subject a fair amount and will be testing out the new sensors with the MAF setup as I read more about the theory and application of speed density. I'm hoping to eventually learn how to apply my own patches to my ROM. For example, I would really like to integrate an accurate oil pressure sensor to tie directly into a spare input on the ECU (my TGV's are gone for example) to drop the IAM and flash the CEL if the pressure drops too low. Maybe that's getting too far into standalone territory though. -Franz The end of a Legacy http://www.youtube.com/th3franz Link to comment Share on other sites More sharing options...
