check here for the history..
after pulley and pfc install with the learning time..
fd is idlin rough.. shes knockin and pingin.. she sounds like she has a bridgeport..
here are the L and T values from PFC..
hopin someone can diagnose as im still tryin to decipher the art of timing..

Key set to on
Leading: -25
Trailing: -25

Idle @ 1200rpm
Leading: 11
Trailing: 3
Vaccum: 18.5

Idle with defroster on @ 950rpm
Leading: 10
Trailing: 4
Vaccum: 17.5

Idle with defroster and fan on @ 950rpm
Leading: 4
Trailing: -6
Vaccum: 16

this is from a virgin pfc....

 

First of all, this should be in the APEXI PFC forum.



You may be in limp home mode. Caused by:
1) Map sensor not connected to UIM.
2) Settings - PIM VOLT not set at NORMAL. Options 1-4 do not work and cause limp home mode.
3) MOP not connected.
4) Hosed ??????

 

apologies.. mods please move..

map sensor connected
pim volt on normal..
mop.. not sure what that is..
hosed.. hope not..

 

? did you get an underdrive main pully?

 

nope..
just alt and water pump..

 

So you just installed the PFC now with the pulleys or you had the PFC working fine before, THEN installed the pulleys and now you have a bad idle?

If it's a fresh PFC installation, check that the proper pins have been pulled or wires removed from the PFC/harness.

 

pfc and pulleys were installed same time..
she ran perfect for the the first stages of learning..
about 10 minutes then she started the bridgeport idle with pingin..
sounds a lot like misfire..
install checks clean... its my second one..

had the second battery checked out afterwards...
she checked out bad.. it was a spare and had been sittin for over a year...
would this cause misfire and pingin... assumption that the injectors or coils are not gettin the proper voltage..

going to try and correct timing with the igt and igl correction test mode...
replacin the battery as well...

the values from the first post above was collected with the idle ig control enabled btw..

 

forgot to mention here the 1300cc install..
mentioned it on the post linked above...

 

injector volume and disabled o2 was the only thing changed...
