EricF Posted November 11, 2009 Report Share Posted November 11, 2009 Can you log throttle position? I find it difficult to believe that timing was retarded all the way to 0.1 degrees of advance... Have you verified the logging's values with a timing light? Quote Link to comment Share on other sites More sharing options...
EricF Posted November 11, 2009 Report Share Posted November 11, 2009 Also, I would be interested to see what happens to the logged ignition timing at 1.2 bar, 1,4 bar, etc. If you have more timing at lower boost levels, it is pulling it because of knock detection, whether it be erroneous detection or not.

ozzimark Posted November 11, 2009 Report Share Posted November 11, 2009 I see you're hitting 100% load. I personally have never seen 100% load, so I find that very interesting... :ph34r: Quote Link to comment Share on other sites More sharing options...
EricF Posted November 11, 2009 Report Share Posted November 11, 2009 I see you're hitting 100% load. I personally have never seen 100% load, so I find that very interesting... You have stock exhaust, boost, and turbo I am not surprised to see you never get to 100%. Quote Link to comment Share on other sites More sharing options...

But seriously, I meant that as, "I've never seen it myself, or seen anyone else hit 100%" Jan's post really sticks out in my mind right now for some reason ;) Quote Link to comment Share on other sites More sharing options...

Sorry to jab at you for the stock-ness, but with your knowledge you should at least have a damn boost controller on that thing If I ever see you and your car in real life, I'll sneak the windshield washer vacuum tee into the wastegate line for ya ;) Quote Link to comment Share on other sites More sharing options...
ozzimark Posted November 11, 2009 Report Share Posted November 11, 2009 Maybe I'll crank up the boost once I fix the mild pinging I'm hearing >12psi. At least my engine compartment isn't a TOTAL disaster, unlike some other people I know On a more technical note.. I really wish I knew how the ECU calculates load. It almost seems entirely based on airflow, and nothing else. As such, the 3" MAF will probably have a huge effect on load, especially since he probably had to do a bunch of scaling within TT to get it set up right. That doesn't change my opinion that Hussein shouldn't be seeing 100% load though :lol: Quote Link to comment Share on other sites More sharing options...
lookforjoe Posted November 12, 2009 Author Report Share Posted November 12, 2009 Can you log throttle position? I find it difficult to believe that timing was retarded all the way to 0.1 degrees of advance... Have you verified the logging's values with a timing light? I can log TPS - in fact, I was before I switched to "load". I assumed load would be more appropriate for gathering data for my TT ECU, since all the tables are expressed in a load %. TPS amounts to the same thing? I have no verified timing with a light. I can see if base idle timing is accurately read -that will at least LMK if the scaling is in fact off. Also, I would be interested to see what happens to the logged ignition timing at 1.2 bar, 1,4 bar, etc. If you have more timing at lower boost levels, it is pulling it because of knock detection, whether it be erroneous detection or not. I've been running 1.55bar on all these charts, except the extended pull to 7K+ in 2,3,4 which was @ 1.6bar, in which the AFR voltage scaling was off because I didn't use a reference ground on the AFR channel. That's fixed now. I'll be testing again @ 1.6bar, I now have a cam cover vent like a Volvo 140 - I vented an old filler cap using the breather line from a 740T & ran it into the catch can inlet. If that cures my oil leak/crankcase overpressure, I'll consider something more permanent (AN-10 lines & fittings, perhaps) Quote Link to comment Share on other sites More sharing options...
maciekb2002 Posted November 12, 2009 Report Share Posted November 12, 2009 take a picture of that , I love retro "fix stuff", I bet you that it will work fly less. I was always having the same problem with my car since I past 20 psi , on second turbo TO4E. Btw I never tried fixed that dump little oil issue by the cap.

dongle Posted November 12, 2009 Report Share Posted November 12, 2009 This is the schematic - I'll take a photo tomorrow I was actually thinking about this last night. Almost sent you a PM asking what you though of it as an option for an additional vent location. I also though about adding one to the blank oil cap location on the exhaust side. Either adding a nipple to the existing location or welding in some aluminum with a bung in it's place. Quote Link to comment Share on other sites More sharing options...
randomdude Posted November 12, 2009 Report Share Posted November 12, 2009 please let us know how this works! even though im not quite at your power level, i wouldnt mind an additional vent. im sorry if this has already been answered, but what was the purpose of T'ing the small line into the big line?

lookforjoe Posted November 12, 2009 Author Report Share Posted November 12, 2009 In initial tests, the vent works, as far as relieving crankcase pressure that was pushing oil out the cap seal over 1.6bar boost on my setup. This is what it looks like right now... 1/2" steel tube insert braised in place.. 1/2 copper plumbing, brass barbs silver-soldered in place.. .. which will be cleaned up, I jsut needed to confirm it would make a difference. I'm going to tap the CC & put a new (larger) port just for the cam cover vent. I'm going to make a solid manifold from breather to CC with a built in vacuum port to eliminate that multitude of connections. please let us know how this works! even though im not quite at your power level, i wouldnt mind an additional vent. im sorry if this has already been answered, but what was the purpose of T'ing the small line into the big line? The "T" is to draw vacuum @ idle at the point that would normally be under vacuum on the stock setup. Probably unnecessary, but I added it when I was trying to eliminate all potential causes of my oil smoke. Quote Link to comment Share on other sites More sharing options...
lookforjoe Posted November 14, 2009 Author Report Share Posted November 14, 2009 Started redoing the CC & lines.. brass fittings/barbs are silver soldered to the copper pipe. drilled & tapped the CC (1/4" NPT, 3/8 port, braised 1/2" barb for breather line) feed to breather is copper manifold with vacuum port, 3/8" barb on one end, 1/4" npt fitting on other vent from CC is 1/2" copper pipe& elbow, 3/8" barb for cc end using Volvo 949701 breather hose (700/900 turbo) it'll look like this in place braised a baffle inside filler cap to prevent large quantities of oil from leaving the head..hopefully it'll work Quote Link to comment Share on other sites More sharing options...
