I Need Help With My MS 1

[smoke187]

keep it red

[vabreaker20011]

yea i think i will do that!!!!

[therieldeal]

well idk ive seen guys run 19:1 17:1 is ok once your warmed up but durring warmup you need to be closer to 15:1

at idle? i'd like to see you get a BP to idle at those kind of AFR's...

even warmed up mine needs to be in the high 13's/low 14's to idle smoothly.

when cold you should be in the low 13's at idle.. really cold (winter) you could dip into the 12's

ok yea i satrted the car yesterday and it was around 7.90 but it was not getting any richer with the ve/fuel adjusted so im not 100% sure my wideband is working right? how could i test it? (wideband)

[therieldeal]

7.9 is rediculously rich, you need to lean it out

i thought it was running too lean?

[vabreaker20011]

the intake tube came off when i dataloged it so im guessing that had something to do with it. but thats why i need to make sure the wideband is working right

[vabreaker20011]

im not sure if my wideband is working right??? whats the best way to lean out the engine?

if you pull the wideband out of the manifold and take a lighter to it
DO NOT light it just let the gas flow into the o2 sensor it should go rich
then blow on it and itll go lean ..

Also do not i mean DO NOT hold it with your hand itll get ****ing hot and give you a blister

before you do that though.. check this stuff
open mtcfg if you dont have a icon in the start menu its in the folder with megatune
C:\Program Files\MegaSquirt\MegaTune2.25\
go to your car defualt is car1
expand it
goto settings
then settings
then lamba sensor
choose innovate lc1 defualt on the right drop down box

close and save settings

open megatune while connected to car
basic settings
exhuast gas settings

choose wideband
switch point should be 2.49
leave the rest of the settings
burn and close

I have done this but the switch point is 2.47 dose that matter?

at idle mine fluctuates between 14-15 warm
cold 12-13

winter it was 11-12 cold

[vabreaker20011]

well i guess the wideband isnt working.....it isnt even heating up and it still reads 7.4 no matter what i do even the lighter trick? man this is killing me got any idea's? its an Lc-1 whats the wiring for this thing? i cant find my diagram ofcorse........ thanks................well i should have it runing good by the end of the summer

[therieldeal]

did you follow the setup and calibration instructions for the LC1? you cant just hook it up and go... it only takes a few mins.

[vabreaker20011]

i hooded it up and i let it set in the open air for like 5 min then i put it into the downpipe... is there something else i should of done?


NVERMIND I FOUND OUT HOW TO DO IT

[therieldeal]

yeah you have to ground out the calibration wire or something... idk i havent done it since last fall

[smoke187]

i didn't have to do a calibration on my aem unit its already done when you get in
