lookforjoe Posted October 28, 2012 Author Report Share Posted October 28, 2012 I will be happier once I have VEMS installed. Then I can run some real boost I know you're working on getting me a copy of that VEMS config, Robbie, I appreciate it. With the current setup, I haven't been really concerned about the AFR's in the lower gears, since 4th is what I'm tuning for. I hadn't considered tuning for under 12.5, that was the range I have been shooting for in 4th. Robbie & JC, what rpm limit did you tune to? What timing did you see up top? I'm also not used to having so much timing up top, I haven't figured out how to properly adjust the WOT & fuel maps for it. I do know I'm on the edge of what the current injectors will handle - 88% just over 7K rpm in 4th. 3rd/4th short pulls today current maps Quote Link to comment Share on other sites More sharing options...
mdlimy Posted October 28, 2012 Report Share Posted October 28, 2012 I cant remember off the top of my head, its been way to long, ill see if i can find a config somewhere(again), but i think timing was relativly close to what you have, i think i had a bit more on the top but afrs where alot richer than you.

fischmama Posted October 29, 2012 Report Share Posted October 29, 2012 H, just an FYI. I just made 315WHP on the 3rd pull at 16PSI (didn't datalog since my laptop ran out of juice just as it got on the dyno) with MS3. That was a 10 min tuning session I did with Joe to dial in some of the fuel switching from greens to the 625cc siemens (now 4bar@725cc). Spark blowout as well as AFRs in the 10 above 5500rpm robbed a lot of power. As a comparison I'll post some maps tomorrow if you want.

Decent numbers for 16psi, sorry to hear about the issues, always something!!

Definitely getting itchy to try the VEMS , if you can locate the files it would appreciated! I do have to do some hardware swapping in preparation for the VEMs, so unfortunately I can't just swap ECUs back & forth :-( Quote Link to comment Share on other sites More sharing options...
fischmama Posted October 29, 2012 Report Share Posted October 29, 2012 Sure! Decent numbers for 16psi, sorry to hear about the issues, always something!! Yeah, but for me just getting it up and goin yesterday it did very well. The engine I have in right now only has about 6k miles on it and it is built (H-beam rods). Road tuning in 40 degree weather is tough...no traction even with the gripper. Quote Link to comment Share on other sites More sharing options...

I wasn't downplaying the fact that you worked it out to the extent you did in such short notice ! Quote Link to comment Share on other sites More sharing options...
JCviggen Posted October 29, 2012 Report Share Posted October 29, 2012 Road tuning in 40 degree weather is tough...no traction even with the gripper. You should be tuning in 3rd and 4th, traction would be allright there with decent tires ;) Quote Link to comment Share on other sites More sharing options...
fischmama Posted October 29, 2012 Report Share Posted October 29, 2012 You should be tuning in 3rd and 4th, traction would be allright there with decent tires Sure thing. I don't live in Germany anymore though. I talked to the dyno guys and they offer dyno time for a fairly good price so I may head back there for a few hours and get some tuning done the safe way.

EricF Posted October 29, 2012 Report Share Posted October 29, 2012 Hey Hussein, you should have the VEMS stuff in your dropbox. One note, I did have a weird breakup around 6100 RPM that the car would not power through, although it may be something hardware related as Karl (Buchka) never had the issue in his car. I only tweaked the fuel and spark maps, so it makes me think it is something specific to my car with VEMS. Worth a note though, in case you get my configuration files up and running and experience something similar. Excited to see what VEMS can do for your setup ;) Quote Link to comment Share on other sites More sharing options...
fischmama Posted October 29, 2012 Report Share Posted October 29, 2012 As promised. Again, around 6k the spark blow out started, its also were the map goes very rich apparently. It will give me a good base to start with. This was with WI on. triggering around 10PSI with a 10 GPH nozzle (630ml/min). Quote Link to comment Share on other sites More sharing options...
blkaplan Posted October 29, 2012 Report Share Posted October 29, 2012 I hope you stay dry through this hurricane. Ever think on installing pontoons on this thing to make it a true XC? Quote Link to comment Share on other sites More sharing options...
lookforjoe Posted November 1, 2012 Author Report Share Posted November 1, 2012 Hey Hussein, you should have the VEMS stuff in your dropbox. Excited to see what VEMS can do for your setup Got power back this morning. We were lucky this time, no flood or tree damage. Unfortunately VEMS does not recognize any of the files. I increased fueling in the top three columns, top three load ranges & increased the WOT values slightly as well. I'll go for a ride later & see what it looks like. I think I've resolved the Logworks errors in IAT (comp, IC & airbox) scaling, so I should be able to evaluate that also. EGT is just off, I have to move the logging probe to the crotch of the header, where I have the EBP port. I don't really need to log EBP at the moment, I know my EBR is very good, and I'm not going to be running more boost than the current 18-20psi range until the VEMS is organized.

lookforjoe Posted November 2, 2012 Author Report Share Posted November 2, 2012 added an extra inlet & outlet bung to my can so I can try a vacuum pump & not dump the outlet externally. Inside of an SAS pump I did a couple of pulls today with a vac/press gauge hooked to the crankcase breather outlet. Absolutely no pressure at at, even at 8K rpm. I may hook up a MAP so I can data log. Quote Link to comment Share on other sites More sharing options...

lookforjoe Posted November 3, 2012 Author Report Share Posted November 3, 2012 Did you tap the breather box for that or where do you tap in to measure? I have a vac port on the back top of the can (inlet side), and also a vac port on the copper pipe running along the block (main breather vent pipe). Today I was measuring from the breather pipe port. I've never recorded any pressure in the can, so I figured I'd better check it closer to the crankcase. I can "T" into the vent off the cam cover as well, just to see what that is doing. The problem with adding a pump, is the vent side could potentially pressurize the can, it pushes a decent volume. I'll just have to hook it up & see what happens. I'm also going to redo my IC plumbing in 3", except for the hotside over the motor. Looking at putting a larger butterfly in the throttle body as well.
