Hello.
Im running F1-C procharger and 90 mm tb so I changed 4349 to .0157 according to writeups here. Made the idle a lot better but now I am sometimes going into reduced power mode and once in while I get a tps error and still having idle issues when coming to a stop. Startup idle is much better though.
I ran a 4307 map to figure out what it wanted for air and added those numbers into the park neutral are. I am in open loop and not sure if those same numbers should be paste into the in gear area.
ETC F11 in iac bid 0-15% has a setting of 2
Because of the idle surging and stalling I started to monitor the iac and found at idle it states iac F10 0-127 giving me a 64. Throttle position is at 5.1 to 6.5 when cold and a steady 4.7 when warmed up at idle.
Idle cold gives 799 to 880 then when warm settles in to 827-880 rpm. iac bidirectional says it wants for 938 desired idle. My desired idle is set to 850.
I am not clear if I should be setting my idle at 938 and go from there and if 5% throttle position at idle along with 64 count is right also. I am thinking this may be my idle problem but do not want to change it till I undersatnd these numbers better and which way to go.
I included my tune and lg file if anyone cold elaborate.
Thank you in advance
