so i installed link and set it for sd for my first start. i have no previous map to go off of. my mod list is up to date and car has had the mechanical and base timing set and checked with a timing light.
The issue i am having is I can start the car and it will idle fine but if i give it gas as the rpm's drop it stalls instantly. when i restart it, the car will idle surge like crazy and die out if i don't give it gas. The air fuel is at 14.7 - 15.3 at idle and timing is at about 12 deg. This happens both when the car is cold or hot and the coolant temp sensor is new and is also being monitored by aftermarket gauge. I also verified the iac is working thru link and tested the unit in another car with no issues.
My question is should i be looking for a mechanical issue or is this something with the tune. sorry i cant post a log at this time as the idle surge is so bad it cannot stay running long enough to capture a log other than rapidly changing values.
