Thread: Check engine light coming on, again..

so i have no idea why its doing it this time, i've been driving the car for a few days on SA now, the first few it didnt come on, i've made changes to the tune but been using the same file basically..

i unchecked the IAT and MAP sensors in the setup because i cant get them to function right in SA, but i have the wideband checked so that i can log the AFR.. which works fine...

it seems to do it just after decelerating, but will stay on for a while when i resume cruising, i've tried pulling codes while the lights on while driving, and while stopped with engine off but ignition on, it says there isnt any.. im confused..

here's a couple logs, im positive one of them, i think the first, was recorded while the light was on, maybe someone can help me figure out whats going on??

OH, and i did make changes to the fuel map an accidently saved it, but other then that, the tcl is the same as i'm running..

I heard if the CEL flickers... it's something to do with the knock sensor.

dOH!

got a link to the thread homie? i think you owe me one???

Owe one for??

And John said it on Facebook A couple weeks ago

by googling i was able to read on their facebook page that it could be caused by the knock sensor, as far as i know my knock sensor works tho.. hmmm?

oh hahah nice timing :P

oh i was joking man, i think u were asking something somewhere and i gave you a link to what u needed, anyway no big :P thanks tho

I initially setup my aircon button as a switch from Set 1 to Set 2 maps, with maf on set 1 and map on set 2. Got the car running ok on Maf, then switched over and tuned it on map. I run map all the time now, just need to get around to removing the maf and redoing the tune for dual Map based sets, and also hooking up boost control!

Try disabling your knock sensor and see if the low load flicker and/or the CEL light goes away during cruise.

This is something we may have to look into as it seems more people are having issues with it, even with a factory knock sensor plugged in.

Also, what is your issue with the MAP feature?

Even if you enable the MAP sensor, you can use it just for logging and not use it for fuel/ignition until you have it right.

Im not sure what the deal with the map sensor is, I cant seem to get it to work right in Sa.. it appears to work fine in Rt tho..

Maybe when we both have time u can remote my laptop again an have a look

Shoot me over your current calibration and I will see what you have going on with it.

I have noticed that the OMNI sensors have been incredibly inconsistent (especially the 3 and 2.5 bar sensors), so as of a few days ago I have started only using the GM 3 and OMNI 4 bar sensors for customer vehicles.

what im currently running can be downloaded in post #1 of this thread thx
