on a turbo b18c1, 10 lb's boost, 310's, vafc. tapped into #1 exhaust tube. when gauge was first installed it proceeded to work fine. now at normal driving speeds, it doesn't seem to work at all. only every once in a while, does it creep up. any suggestions? thanks BTW- the gauge ranges from 600 to 1600.

have you checked your connections,what temps where you getting?

11secdx

it is not reading anything. needle stays under 600. does it need to be cleaned ?

civictypenos

have you checked your connections,even at idle will be above 800,are you turbo?

at idle mine reads about 950 and cruising on the freeway I get about 1400, boosting in 3rd gear gets me to 1600 but thats as high as my gauge reads. Is that too high?

1600 is VERRRRRY lean

Wo-Nelly

On the dyno, the wideband reads 12.0 across the whole graph.

i am pretty sure the connections are good. i will be checking them here in a little while.

E-Rok

wow, especially since you said it pegs out on the guage

TORQUE MONSTER

yeah man u wnt to have that cheched out cause 1600 is way tooo high

TORQUE MONSTER

actually do this.. throw in a set of fresh plugs run it so it hits 1600 and stop the car immidiately and take out the plugs and see wat color the plugs are.. if its white and looks burnt.. its too lean.. if its all black ur cool u may have a faulty guage

Acutally what the gauge is showing you if you say it is tuned to a 12.0 AFR.

Is that the timing is to low, and you should add a little more advance to it, to bring those temps down... mine used to do the same thing, then i added some more timing and now i hit 1400-1450 under a hard third gear pull at 20lbs.
