Ryan Simmons Posted March 17, 2010 Report Share Posted March 17, 2010 Hi, i own a Linkplus g3 and am using it on a 2.139 stroked 4-cyl 3s-gte turbocharged engine. I am having some quite bad issues at the moment during cold start / warm up. Basically, when firing the engine up from cold, literally after a few minute the plugs have become so thick with black soot from too much fuel that they start to misfire quite bad and does not improve when the engine reaches operating temp. Also i cannot get the idle to stay steady, its always bouncing around from 800 ~ 1200 rpm (idle is set at 1000rpm roughly). I do not know that much about actually tuning ecu's but if there is any information/data you wish me to supply, i am sure i can help. I am running 1200cc injectors, 35psi base idle FP and a Link 7bar map sensor. Cyl compression is good and consistent throughout all cyls. Then when we tried leaning out the warm-up enrichment the idle got much worse and the engine cut out. I also noticed that my TPS reading was jumping from 0~15% every now and then, perhaps this could be the cause? I disassembled the TPS to find it was full of water and muck, so i cleaned it out and it appears to be working better now, however i still have the misfiring. Can anyone help?!
