Hey all you MS gurus!
Had a friend affiliated with a group of well-known MS tuners here in the NW work with me on tuning my 2L 16V ITB Golf. All has worked pretty well (Thanks Guys!) - however, I'm having quite large issues with higher altitude sputtering, bucking and running super lean - as in making no power to go up the mountain roads. I've looked at the tune and added EGO corrections for Control Step size (2) and Controller Authorization (12%). Previously these were "0" on both - oops. I know I can turn EGO correction on in the Lambda settings (Lambda Sensor targets), and then use the VE Table for the AFR Target table. However, I wasn't clear on editing this table so tried a bit with the default AFR table, but with no change, I turned that setting off again.
The problem I'm seeing is at anything over 2000ft, the map will not read above 54kph and the fueling on my AFR (AEM UEGO) is literally off-the-gauge, lean when trying to put any throttle beyond about halfway. I was running the laptop while driving yesterday so I could run a few Datalogs of the issue. I even tried adding a few more bits of fuel to the VE Table in that RPM area - around 2500-3000 - but no change.
Are there any suggestions or anything I can do to get the car running better over the mountain? I can't be stuck to just sea-level driving!
I have the datalogs and all the deets, if any of the gurus are interested. Thanks all!
