already tried using VPC to run lemmiwinks...no luck...usb to serial adapter used...decided to spend $300 on ebay for a decent pc laptop to make sure i could use lemmiwinks and vag-com
Speedy there as some good and bad news, the bad news is that we can't use Lemmiwinks on our cars, even disconnecting the intrument cluster fuse, well at least with my HEX-COM with USB adapter.
The good news is that we CAN change adaptation channels with VAG-COM but with some limits, log ENGINE -> ADAPTATION, the channels that AEB and AGU engines have are the same as those shown on Lemmiwinks screenshot, at least they look like them.
I adjusted start up fuel enrich to a lower value, warm up fuel enrich to smooth the idle on the morning, raised the speed limitir 30km/hr, lowered primary fuel tweek to match my fuel trims, lowered fuel tweak increasing loads to get a leaner mix up top and decreased timing offset by 10 points (don't know how much is it in degrees) so it's gonna be a trial and error procedure until we get this sorted out.
Looks like the car runs much smother now no VAG-COM logs yet though, give it a try and let me know [IMG]http://**********************/smile/emthup.gif[/IMG]

Thank you sir
Perhaps that should be at the top of the guide
Quote » Primary and Secondary fuel tweaks should only be used to bring your fuel trims back to 0.0 They do richen and lean the mixture but your ECU will try to adapt so they are truly only useful for bring trims back to 0 or adjusting the mixture and staying within the limits of plus or minus 10% .
Example, lets say you unplug your MAF and drive your car around for 50 minutes to let the ECU adapt out the richness. Lets say your trims end up at -9% and -18% (typical). You can use the primary fuel tweak to correct the off idle trim by lowering it 18% then resetting your ECU.
On the above example you could lower your secondary 9% to bring the idle trim down to 0 as well.
Interesting. were you able to tune enough to get a relatively flat and consistent A/F curve with Lemmiwinks?
has anyone ever tried to use this with a hard wired neuspeed chip? we tried it on my friends car and when trying to connect, it came up w/ the dialog "Har Har Har Har...", i figured it was because lemmiwinks cant communicate with it, what do you guys think, if this has been asked before, forgive me
Sometimes I get a "Hey... NAK NAK NAK" error message. If you try to connect again and it doesn't go, usually switching the igntion off and then on again will fix it. If this doesn't work then something you are trying to do is not compatible.

like when boost comes on.
i would agree... it would make sense that it's talking about the enrichment off the map sensor (in boost) instead of the MAF

oh, thats the message, it was a couple weeks ago.. my brain is failing me lol, he has the HEX-USB, and got the software port converter so its seen as a serial connection, ill tell him about the ignition on and then off again, he problem couldn't be with it being an actual 'chip' and not software flash? anyone know if neuspeed does something different so that those fields cant be accessed?
hmm I was testing lemmiwinks, Vtune and the old version of vagcom with the cheap obd2 cable I bought from egay, hmmm everything works, I can change stuffs in lemmiwinks & vtune, it sucks though with the vagcom, I think I'll buy the real thing, but for now it's looking great.
Hi, I was wondering for an exhaust that is backfiring when you leave off the throttle do you adjust " Ch03 : Fuel Tweak (Accel Pump); Decreasing Loads" up or down to minimize the backfiring? Example 115% or 85%???
I also checked block 032 and it shows +1 and -3.1. Does that mean that I use "Ch08 : Secondary Fuel Tweak" and put in the value of 101% and for "Ch10 : Primary Fuel Tweak" put in the value of -3.1% to even out the trims???
Thanks for any help.

It all depends on when the last time you reset your ECU or cleared codes. +1 and -3.1 is pretty good for long term fuel trim. Last I checked, mine wars -0.4% and +2.x%
