Hey everyone I'm new to the realm of stand alone computers so don't bash me to much! I have a 85 Rx7 GSL-SE with a stock s5 turbo II engine. I recently installed a Haltech ps1000 computer system with the 13b wiring harness provided from Haltech. Here are the mods that I have done to my car besides the swap; I have a new Aeromotive A1000 fuel pump and efi regulator set at 45psi base. A Racing Beat 3" downpipe without any exhaust so far. Other than that the engine is stock. Now my problem is that I am having trouble getting the car out of vacuum into boost. At any throttle position unless I feather the gas I cannot get my car to rev past 2500-3000 rpm with popping. The few times I tried to drive the car around my block the same symptoms occurred. The car idles smoothly and starts up very nicely but as soon as I get to zero load (vacuum) around 2500 rpm she will pop and fall on her face. Could not having any exhaust from the downpipe back be causing this problem? As I said I'm not experienced with stand alone computers so I don't plan on doing the fine tuning myself but I cannot even get the car drivable enough to depart on my way to the muffler shop or tuner. Any suggestions or help of any kind would be great!

 

Needs tuned. Simple as that.

 

Well I guess you answered my question... Thanks!
