Hi Eric,
I have purchased a Typhoon where the previous owner had a known issue that the truck was running super rich at Idle.
Since purchasing I have completed a number of jobs to try and get the truck up to speed however I'm stumped at this issue.
The TT chip is 15542 for 60lb injectors and 3bar 93 fuel with a AEM WB.
I have double checked the vac lines and have replaced as required., confirmed 60lb injectors are installed and fuel pressure at 42psi (lines removed), checked the coolant sensors are providing resistances as expected. There is a 3 bar fitted but appears to be a cheap item so not sure if this is causing a problem. The ignition timing has been set with the tan wire removed so believe that to be good (haven't checked balancer has spun though). I have replaced the fuel pump for a new unit along with the filter so confident that the fuel system is in good condition.
I have the same setup in my Syclone and was a simple plug and play and was able to trim the AFR to 14.7 ish with the pot on the board and has behaved perfectly since installation.
Here I have the trim all the way down but doesn't appear to be pulling enough fuel?
I have attached the below log from a cold start and let it run for nearly 10 minutes. Can you please kindly have a look through and let me know your thoughts?
Regards
Marcus
