check what other people have in their logs. You are missing wgdc, rail pressure, lpfp, among other things. my advice would be to get rid of cobb for mhd. Those maps are nasty

your lpfp is holding pressure fine so i would add another gallon of e85 for sure and see if it improves.

Thank you for the help! Another thing I noticed was my boost not hitting target. Am I misinterpreting the graph or do I have a leak in you opinion?

Id say not quite enough E. I go 4/10 or 5/10 lately (this maxes my stock LPFP on 2+ though)! But my base fuel is crap ACN 91. So try 4 gal E85 / 10 gal 93. Also yea your below boost target all the way so maybe a leak but its not terrible.

Replace boost solenoids, check for brittle vaccuum hoses esp under engine cover, replace chargepipe O-rings from diverter valves, check all intercooler connections etc...

Change the opton for boost to boost mean Yes, there are no timing pulls but you are in third all the way. Shift into 4th for a bit and let it get a few secs in that gear. You arn't getting retards but the Ethanol isnt really helpig much since you are still on a 93 map. Its only got like 6 degrees of timing. A e30 map would kick that to 8 or 10 at least. Barometric pressure is 14.2 psi. Thats about 1000 feet elevation - as you move up in RPM the fuel trims wont be as close as it would be for an OTS map on a car thats at 14.7 psi (sea level). Custom tune is the fix for that. That in an of itself isnt a reason to go custom tune, its just one.. of some .. Your IATS go from from 72-73 degrees to 92 in about 6 secs. https://datazap.me/u/volfwaley/stage...-29&zoom=22-84 So what Intercooler is this? The wastegate DCs are up in the 70 percent range at the top of third.. You wont get much more out of it than that. the snails are moving as fast as they can.

Turn off boost P and D fact and turn on Short term fuel trims.

if you're driving the snails to 65-70 percent DC to get close to target boost you wont get much more. Here's my suggestion, dont try to use an OTS map to meet your needs. Bite the buttlit now and get a custom tune. Someone with some n54 specific info will keep you in the sweet spot as things change. For one, a little more fuel will help keep IATs down a bit. They can also do some predictive stuff that will keep you out of retards right after the shift (when throttle closures become an issue).

Can someone take a look at my log and give me their thoughts on why it's running so lean? I did a baseline data log of my car before putting a tune on. I noticed it's running a lot leaner than I expected (13.5-14 AFR) and I saw some timing corrections on all cylinders. I got new plugs and coils so maybe that will help with the timing but what about the AFR? Thanks |
