The bins are stock. Has the car had enough key cycles with the chip in to start learning trims?

hi galapogos ..

i have been busy with other work but have had some success getting timing changes ..

i maxed out the mbt tables (with 55s) and bumped the bdln knocks up heaps .. seems to give a decent result .. especially down the revs .. i also swapped around the tables so i had 55s in the bdln knock tables and got a slightly less consistant result ..(pulls timing more widely it seems) ...

i also modded the "#3 #4 dont use tables" with no negative results .. i did this out of desperation and at the same time as other other changes, so im not sure what impact it really had but things started working at that stage. .

but im still not getting any LTFT or lean cruise .. economy is not very good ..

Try from a stock bin again and use the latest def on the site v6 - Kendall worked out an issue with the labeling on the timing tables.

We're you getting trims with no chip?

Cheers,
Jason

How do you know there is no lean cruise? I monitored with a wideband... noticed with an 82deg thermostat it didn't engage lean cruise, so the min temp must be quite high (EL ECU).

On another note galapogos01, does the problem with the AC being permanently on still affect AU's?

Im assuming itll show in the scantool. Did you have your O2 connected when you tried or just the wideband?

True, if you can monitor LAMBSE or o2 Voltage (It should be 0V) in forscan.

Another thing- if you have a problem with the 02 sensor it wont cycle enough times to engage lean cruise, as you need a certain amount of cycles to enable it.

guys ...

i was running forscan looking at ob2 data on the std ecu for a while (with no j3 fitted) .. i have a wideband bung welded in separately to the the std o2 .. wide band was confirming the lean cruise ..

forscan reports closed/open loop and stft/ltft .. great software (major advantage over eseries' total lack of live data) ..

as for thermostat, it has not been changed and i def did see in lean cruise on the VCT ecu (ive also got a std non vct ecu i have been using but didnt monitor it much previously and am now running it with j3 - i dont see why it wouldnt perform the same) .. but interestingly the vct did not enter lean cruise all the time (or not as often as i expected) and yes the temp is on the low side ... i have some logs with the ECT and CHT but off the top of my head im not sure of temps it was running at (seem to remember it being around 82ish) ..

also i have the permanently on AC issue (compressor cycling and left fan on all the time) .. looking at modding the main on/off switch and relay circuit to get around it ..
