Title: How can I tame knock? Post by: dokalanyi on November 21, 2016, 05:46:24 AM Been following the 1.8T community tune, however, correction factors don't make me feel safe continuing.
I'm getting knock when I've barely increased LDRXN -- Actually, I had to increase LDRXNZK, it's not following LDRXN. - I've tried using the best fuel I could find (Shell V-Power), for a week, to clear out any "old" fuel. And also cleared errors to reset trims - My suspicion is maybe intake air temperatures are high? - I tried waaay running rich at one point I've attached the latest log I did. Ambient was around 19C/66.2F EDIT: I also have these 2 error messages, almost always. I never disconnect my battery, and I've replaced the vehicle speed sensor on the gearbox. No ABS errors 18010 - Power Supply Terminal 30 P1602 - 35-10 - Voltage too Low - Intermittent 16885 - Vehicle Speed Sensor P0501 - 35-00 - Implausible Signal Title: Re: How can I tame knock?

TABGBTS is set to 1050C IAT aren't great, but timing curve needs some work. Too advanced by 4,000rpm. It's stock timing, that's why I thought I shouldn't touch it Title: Re: How can I tame knock?

Your IAT is too hot, thats all i tell you. Title: Re: How can I tame knock? Post by: dokalanyi on November 21, 2016, 12:18:21 PM How do I drop IATs? I'm in a tropical country, temperatures are 22-30C all year, almost all the time.
FMIC: - Expensive to ship -- more than the cost of buying the front mount intercooler itself - Waters/Meth: easier to ship, just worried about water consumption. What's your take as a hack for this?

Title: Re: How can I tame knock? Post by: dokalanyi on November 22, 2016, 01:52:26 AM Are you running spec coolant? if you or a previous owner didnt run proper g12, g12+ or g12++ coolant then you likely have excessive buildup, rust and or/deterioration somewhere within your coolant loop. and if this is the case your pump could have gotten clogged therefore your cooling system can no longer dissipate the heat produced by your engine. I'm definitely not running spec coolant. But the coolant temperature is actually always around 90C (even in the log, not just the cluster). I'll try to flash the system with spec coolant to get that outta the wayFirst things first can you hear your radiator fans functioning at all? you should have 2. a large one and a secondary. In your tune you can change the threshold temp your fans will kick on at. Check that and make sure you dont have it set too high. Lower it and make it come on at a lower temp. The fans work. The second one mainly comes when I turn on the AC, and when I start the car, then goes off.Title: Re: How can I tame knock?

Stop making shit up :P Title: Re: How can I tame knock? Post by: adam- on November 22, 2016, 02:36:17 AM Coolant temp didn't budge from 90 (+-1 deg). That won't change AITs.
Don't trim logs either. Title: Re: How can I tame knock? Post by: IamwhoIam on November 22, 2016, 03:19:40 AM jeeeeeeeeeeez
Title: Re: How can I tame knock? Post by: aef on November 22, 2016, 05:31:25 AM Start with a Mercedes Benz Sprinter Intercooler if this is a option for you.
Title: Re: How can I tame knock? Post by: dokalanyi on November 22, 2016, 09:19:12 AM Start with a Mercedes Benz Sprinter Intercooler if this is a option for you. Good suggestion actually -- seeing as we get all our spare parts by importing old cars used cars that have been "cut". So only OEM parts are available locally. The Benz intercooler looks front mount, fabricating that piping won't be trivial, unless sprinter pipes can be adapted. |
