Has anyone noticed there lc-1 being slow to respond to afr changes, im not sure whats the issue.
I am Logging with the gps unit and previously havnt noticed a problem untill around the same time i upgraded injectors.
Now when lifting of the throttle or coming onto it after coasting there is a good 4-5 seconds before the expected reading appears.
for example after doing a pull and letting off the gas i continue to see an afr reading of 11.8 - 12.2 for aprox 5 seconds before the afr pegs due to the injectors being shut off on decel.
The same goes for applying the throttle after decel it gontinues to show afr of 50.1 for example before updating to 12.5 or whatever the true afr is at that time.

I am unsure if this is a result of the injector upgrade and subsequent scaling alterations or wether its an issue with the lc-1, it is approx 8months old and has had little use allthough recently it did throw an error 4?

Any ideas welcomed. Thanks

 

how are you logging?

 

sorry im not quite sure what you mean by how, if you mean how am i logging afr?? its by usb input from the lc-1 into the gps nav

 

so evoscan gps nav?

are you running the most recent version of the software?

I know evoscan 2.7 had an issue with the MTS programming...

 

so which evoscan should we use? 2.6?

 

yes im using evoscan gps nav, with the version it came with. Thing is i dont remember having this problem initially its only just developed around the time i replaced injectors which coincedently is also around the time it threw an error 4

 

just run the latest...

 

after the problems im having with my lc1 and evoscan (trying to get it to read properly for ~6 months now) im about to throw both out the window and go pay for a tune.

currently my reading sin evoscan are way off from what shows up in logworks.

for what its worth i put in a brand new sensor and response of the logged values seems to increase.

 

^ what version of evoscan?

 

currently running 2.7 (have a thread going in this forum if youd like to take a look so i dont clutter this one further)

 

upgrade to 2.8.0005 and I bet a lot of your problems will be solved...

LC1 is fickle, I had to put a delay-on circuit to stop the low voltage while cranking from resetting the damn thing...

 

in LM programmer there are sensor response properties, iirc 1/4 second, 1/2 second, 1 second and instant. make sure 'instant' is checked

 

thanks will check that and update

 

was there a known issue in 2.7?

and yes very fickle, if it hadnt come on the car when i bought i would be running something else.
