East bethel,
Minnesota
Just bought a 1998 GSX manual that has an ECM link V3 HX35 1200cc injectors FPR not sure about the fuel pump but it was upgraded i think since it made 400 wheel on the dyno. The story so far is the car has been sitting in a garage for 5 years and i bought it from this girl who owned it that doesnt really know what her EX Boyfriend did to it.. I have dyno papers of it but im pretty sure that it was tuned on MAF not SD by DB performance in Minnesota. Iv watched many videos on these cars and ECM link and SD im just trying find someone to kind of get me set up where the car will just idle before i bring it in for getting it tuned i also bought this car to learn how to tune it but finding out SD tuning is harder over MAF. So i took apart the AFR and TRU boost Guages to find out the AFR guage is the older one that connets to ciggerete lighter and the other plug goes into my drivers seat plug that i think is the rear o2 plug? I think i will need a new AFR X series guage to connent to my ECU so i can read wideband info on my logs? Im pretty sure my connections for SD work fine in ECM link. I have made a log of the car starting cold my FPR shows like 48 on the guage and my SD map is super red ive never seen other maps look like that but i don't know what to really change since im not sure if everything is reading correctly. Reading my AFR guage when the car starts and warms up it starts at 12 and keeps going up and starting stumbling after 15 AFR and maxes out after it starts running bad. Old gas has been flushed out and plugs are new. I will make a video tomorrow of the car starting and show AFR gauge to make it easier to see what it does. it has no codes
