Title: Timing Map Tuning - Summer time or wait? Post by: AudiMan85 on August 06, 2014, 12:40:05 AM Hey, ok so I wanna make some changes to my tune. I'm happy with it but it's a dog right now in the summer heat. My intake temps are crazy right now when not moving and when at WOT.
So my new investment is a w/m kit new week and I need input on tuning my timing maps. I have added the switching maps phila_dot has provided and have setup 2 map sets. Stock and Stage 2++. Now should I wait to do my timing tuning or any tuning til after the summer? I plan on 3 map sets stock, Stage 2++ (NVR's) and 3rd the meth tuned timing maps. So this would all yield better in the colder days for more base power. Should I just wait and let the ecu pull timing in the summer based on IAT? Title: Re: Timing Map Tuning - Summer time or wait?

If you are not moving, no cooling air from the cars velocity is present, allowing the temperature to increase in any way it pleases. ;) Title: Re: Timing Map Tuning - Summer time or wait?

Load reduction does that count in these terms then Title: Re: Timing Map Tuning - Summer time or wait? Post by: phila_dot on August 06, 2014, 07:04:50 AM KFZWWLNM
Look at function ZWWL, dzwwl offsets zwgru for zwbas. Title: Re: Timing Map Tuning - Summer time or wait?

I thought that was knock based enrichment .. not as the op was describing ie timing pull because of higher iats. Title: Re: Timing Map Tuning - Summer time or wait?

It has nothing to do with knock or enrichment. It offsets ignition angle for iat and coolant temp. Title: Re: Timing Map Tuning - Summer time or wait? Post by: AudiMan85 on August 06, 2014, 12:17:03 PM Ok, just wanted to make sure I wasn't going to waste my time tuning in the summer. I know the air temps at idle are gonna rise. I have been doing stuff like this for awhile now, these ecu's are just alittle different to tune and also my setup is different also. My last car has a FMIC bigger then I think the front of most of the A6's would be able to handle and stage 3 devils own progressive kit and I tuned in the normal temp months. I just love watching old logs of intake temps of 80* and now I can't even start the car with anything less, with in 10mins of driving I'm at 120 while driving and upto 200 while under load/boost. Then while standing still the heat soaking is killing me til I get driving for a good 10 mins or more.
Just had to ask, I still have timing retard set to 15* I should keep it there correct? And also I kept enrich maps where they were prior too. Thanks for the input guys! |
