99 GSX. Ecmlink, Help with initial tune before dyno time is schedule
Hello I recently posted on the ECM forums and have received a decent amount of help. But I wanted to start a thread on tuners, since this is my main dsm forum to post in. So....
Long story short. I found out my ecu was damaged and causing the injectors to over fuel the motor when cranking. I have a new ecu and v3 chipped installed, with all fresh fluids. The car is running. Now that your caught up. Here is what i am trying to accomplish with this thread. I want to get the idle and initial part of the tune setup better. Once I have that down it will be going to the tuner for the final touches.
Car Specs: (I bought this car in April, and im still learning ecmlink)
-1999 Eclipse GSX
-5 Speed
-Chassis Mileage 87k
-Built 7 Bolt Block (Arias Pistons, Manley I-Beam Rods, ARP Hardware, Stock Crank, ACL bearings, etc)
-7 Bolt Head (Kelford 272 Cams, AEM Cam Gears, 3G Lifters, Supertech Valvetrain etc)(one thing that's interesting it has a 1g CAS on it that functional
-Bolt on’s (Magnus Street Manifold, 1G Throttle Body, FP 4” Intake, ExtremeMotorsports FMIC kit, DNP exhaust manifold, DNP manifold PTE6262 BB T3 .82A/R, Apexi exhaust etc)
-Tuning (ECM Tuning, AEM IAT, AEM Map 3.5 bar I believe)
-Fuel (Jay Racing 343 Kit, STM rewire, FIC 1450’s)
