fishbone Posted July 2, 2009 Author Share Posted July 2, 2009 Say, I am running stock spec NGK spark plugs which I replaced 10k miles ago. I'm being told that 1-step colder plugs fight knock and may do better. Do you guys think that may make a difference? Link to comment Share on other sites More sharing options...
qikslvr Posted July 2, 2009 Share Posted July 2, 2009 I got your mesage, but won't be able to make the trip... I'll call ya back later. As for the plugs; I put 1 step colder in when I/we put the 20g on and tuned for it. I didn't see any real differnce then. And now with the stock turbo back on for a minute; it appears to make no difference what so wver. My "allowable" timing curve is identical to that of the stock plugs and maybe even a half to a full degree less. Go figure:confused:. Let's kick this pig!

fishbone Posted August 3, 2009 Author Share Posted August 3, 2009 What the hell? Did Mr Knock find his way back into my tune again? I logged Seconds instead of Intake Temperature somehow ... These logs were taken in 94*F, intake temp was above 105*F Log 9 is 1-2-3 to redline I'm looking solely at dynamic advance which should be pegged at 8 all across, am I correct?datalog6.csvdatalog7.csvdatalog8.csvdatalog9.csvdatalog10.csv Link to comment Share on other sites More sharing options...
qikslvr Posted September 1, 2009 Share Posted September 1, 2009 Fish, a couple of those logs looked fairly good actually, but there are a couple with some knock too. Most of the knock in the first 2 or 3 logs is "shift knock" and we all get it even in the 5MT's. The last two had a little in gear knock, but that looks like it at points where you are overshooting boost targets and the ECU is pulling some WGDC to drop boost back within the requested range. I'm a little concerned about the long term fuel trims as they are basically pegged to the negative. This means that you are running pig rich throughout the WOT pulls. We really need to get together in the near future and do some logs with RR and maybe even let me pull the ROM off your car so I can look at it. Joeleodee got a copy of StreetTuner and we installed it a few weeks back, so we need to do some tuning on his ride too. I'll be putting the 20g back on shortly too, so I can give you the ride you didn't get the first time it was on. Joel is pretty busy at work, but I should be able to run down there anytime during the day or I should be able to talk the wife into visiting her G-ma/G-pa some evening when you and I could get together. I'll be in touch and we'll figure out a time when we can hook up. Try getting a couple more logs now that it has cooled off a little and we'll se what she has to say. Let's kick this pig!

fishbone Posted September 1, 2009 Author Share Posted September 1, 2009 Thanks for reviewing qikslvr. I think that I uncovered a case of user error. When Jarrad sent me the last revised map, he had me flash it realtime instead of a base reflash. My AP mainboard has failed (to the tune of $250) and had to send it in to Cobb for fixing. When it came back, the AP was still married but it was not aware of which maps were loaded onto the vehicle. About a month before this, I had a CEL due to the missing sensor in the UP and finally took the time to shove the resistor in there. Upon clearing the CEL, I also cleared the ECU and, you guessed it, took away my revised realtime map. So upon reflashing the BASE, I did some runs and I can't get the DA to NOT stay rock solid at 8, no matter the gear, no matter the revs. The only thing I'm not sure of is it dipping in negative numbers when not under load or when lifting off. I'm guessing it's normal. I've seen as much as over -4. I'll do some more datalogging sometime soon and see how she runs. Link to comment Share on other sites More sharing options...

fishbone Posted September 1, 2009 Author Share Posted September 1, 2009 I know and I agree, especially because I've had the thing sent in a total of 5 times now, I think. It was the first time out of warranty work and to be honest I wasn't expecting to have to pay for it, for some silly reason I thought the AP had lifetime warranty on it Next time it fails, I'm going opensource.

fishbone Posted October 1, 2009 Author Share Posted October 1, 2009 This question has been nagging me lately and I know that I should just f/u with PDX but I can't right this very moment. Would there be a reason why he would not be able to bump up the target boost from 17.1 to 18? With the Perrin TMIC, I'd probably actually push over 19PSI of boost. Is that not safe? Mod list: Perrin TMIC Autospeed catless UP Gutted shorty DP with one cat left, all stock exhaust So I am basically on the stock exhaust except for the UP, with one cat left to avoid smell issues. What goes hand in hand with raising boost from a tuning perspective? We had to stay on the conservative side as far as timing/advance goes due to some knock issues.

scoobydoobie Posted October 1, 2009 Share Posted October 1, 2009 I dont see why not. My TA map has a target boost of 19 psi. And I have very similar mods as you (AVO TMIC, GS exh. manifold, GS UP, Cobb HFC DP, stock CBE) Link to comment Share on other sites More sharing options...
MM Legacy Posted October 5, 2009 Share Posted October 5, 2009 Looking for a little help. 2007 LGT-Auto Stock Turbo Headers Cat-less up & DP & full exhaust COBB AccessPort running stage 2 map I have the pro-tune software that allows me to create or edit any map. I have 21 passes with the stage 2 map (logged) for review. I messed with the COBB map by making small increases & decreases to any areas COBB changed versus the stock map. Loaded and seems to make more power and kick in at a lower RPM. I also raised the redline 400rpms to allows the headers to perform. The Stage 2 map from COBB is built for 93octane with stock intake, cattedDP and Cat-back. I am running a cat-less system with headers. Does anyone have a map they would care to share or suggestions on what to adjust to get out more power from the COBB stage 2 map? Thanks Chris Link to comment Share on other sites More sharing options...

qikslvr Posted October 7, 2009 Share Posted October 7, 2009 ^It's quite an involved process. I'd suggest opening a separate thread +1 this is Fishbone specific thread. Sorry:redface:. I think he just wants to stay on the conservative side with your tune since it went way off the deep end early on. There really isn't a reason not to if she's finally running clean and consistent. You have always boosted at least 1psi over target boost(and sometimes more). Also the VF40 starts pushing a lot more heat above 18.5psi. There is only so much you can get out of that stock turbo. In order to increase boost at this point in the tune you would pretty much just need to increase the target boost and the WGDC just a little to up the boost. You would then check for new knock and back timing down where needed if there were any. I also don't think there is much benefit to pushing this turbo that hard. Even on my setup with the Header/UP, TMIC, Intake, Inlet, BCS, Full 3" Exhaust and all the other parts; I won't push it any furhter than 18.5psi without my Meth kit installed. We just need to get together so I can use your AT-R to tune that beast and finally get it done right;). Let's kick this pig! Link to comment Share on other sites More sharing options...

fishbone Posted November 21, 2009 Author Share Posted November 21, 2009 Flashed Cobb OTS Stg2 91 this morning. Learning view and logs. IAM started at 0.88 right after I flashed it and then climbed to 1.0 and never went below. What is the DA set to on these maps?datalog1.csvdatalog2.csvdatalog3.csvdatalog4.csv Link to comment Share on other sites More sharing options...
iNVAR Posted November 22, 2009 Share Posted November 22, 2009 If you have romraider, you should be using that to log, not your AP. And log these: Engine Load (2-byte)** (g/rev) Engine Speed (rpm) IAM (4-byte)* (multiplier) Ignition Total Timing (degrees) Knock Sum* (count) Manifold Relative Pressure (4-byte)* (psi relative) Mass Airflow (g/s) Mass Airflow Sensor Voltage (V) Primary Wastegate Duty Cycle (%) Throttle Opening Angle (%) Some of these are "extended" parameters and they will not show up on the log list unless RR is connected to your car, so connect it first and THEN choose the parameters. And I personally like to log these, too, but have been told it's unnecessary and wastes bandwidth. Knock Correction Advance (degrees) Intake Air Temperature (F) You can also log these but again, the more parameters you log, the logger the interval between each row. Feedback Knock Correction Fine Learning Knock Correction Based on the logs you did though, I'm positive you're getting knock. I'll pullup the DA table in a sec and show you what it's supposed to look like. Link to comment Share on other sites More sharing options...

fishbone Posted November 22, 2009 Author Share Posted November 22, 2009 I'd love to log with RR, I agree it is MUCH better than the AP which makes me feel I am flying blind, but the damn VAG-COM cable cuts in and out. Working towards a solution. In the meantime I'll just take it slow with the car. Link to comment Share on other sites More sharing options...
iNVAR Posted November 22, 2009 Share Posted November 22, 2009 wanna know something funny? that used to happen with me too when my ap was still married. i unmarried and went OS, and now it's stable as hell on RR. used to cut in and out sometimes with tye ap too under wot.

iNVAR Posted November 22, 2009 Share Posted November 22, 2009 i'd take it REALLY easy on the car. based on the table here's what i can see. you're pulling a crapload of timing starting from 4000 RPM. compare it to the figures in the table. you're actually seeing negative numbers in 5600+ range in some of your logs. your LV isn't going to be that useful from what i understand because (and i think you yourself noted this) the cobb maps have FLKC DISABLED at loads above 2.2. your ECU will NEVER learn to retard the timing at those loads and RPM ranges meaning your car is going to rely on FBKC and... i think ROUGH correction (by reducing your IAM/DAM) Link to comment Share on other sites More sharing options...
fishbone Posted November 22, 2009 Author Share Posted November 22, 2009 I'm wondering if I should have stuck with the PDX map for now and just taken it easy. Should I just flash to the Cobb ACN Stage 2 91 map for now? Seems that it's designed for crappy 91 which is the case for Nebraska too it seems. It's a more conservative tune.

iNVAR Posted November 22, 2009 Share Posted November 22, 2009 Hmm, I dunno what to tell you. I don't think it can hurt to flash the ACN map. Link to comment Share on other sites More sharing options...
fishbone Posted November 22, 2009 Author Share Posted November 22, 2009 I'm going to try to log with Accesstuner Race using the AP dongle. Link to comment Share on other sites More sharing options...
iNVAR Posted November 22, 2009 Share Posted November 22, 2009 It doesn't log the parameters I listed either. You need RR. I had an AP. Trust me. I know what it can and can't log. Link to comment Share on other sites More sharing options...
qikslvr Posted November 22, 2009 Share Posted November 22, 2009 After looking at the logs and the learning view that you sent me it is starting to look like there is just no hope in getting that tune to run clean. You and I just need to get together for a couple hours soon and I'll get your timing issues resolved and build you a clean map. I've started over so many times in the last two years; it only takes a few minutes to get things started with AT-R. After a few logging runs we'll nail the timing down and then see what she'll give us for power. We did Joeleodee's with ST in a matter of minutes and now I can make changes with ST-A and e-mail them to him. We would just need to migrate a copy of AT-R onto one of my computers so I could remotely edit the maps if need be. Your IAM/DAM should climb to 1.00 and stay there if the car is running well at all. You've seen my map collection. Not one of them EVER drops the IAM. Let's kick this pig! Link to comment Share on other sites More sharing options...
fishbone Posted November 22, 2009 Author Share Posted November 22, 2009 Mark I agree, there's been so many changes to the map I have been running all this time that I just don't see how it can be ironed out. When I switched to the Cobb OTS I was surprised to note that the difference was not THAT big and the Cobb map was actually smoother. I loaded up the ACN version of Cobb OTS Stage 2 91, it's supposed to be set-up for crappy 91-octane in Arizona, California and Nevada. Take a look at these logs. Also included a screenshot of the DA table for this map.datalog1.csvdatalog2.csvdatalog3.csvdatalog4.csv Link to comment Share on other sites More sharing options...
