SpeedNeeder Posted November 7, 2006 Share Posted November 7, 2006 yeah, i would like to see never mind, i know tdc doesn't like logs of their maps floating around My other car is a 1993 Chevy S-10 Tahoe!

legacy_y_tu Posted December 11, 2006 Share Posted December 11, 2006 Well I finally got around to do some datalogging. I'll say it was easier than I thought it would be. Definitely due to all the writeups on here. Only thing is I recorded the A/F readings in Ma it appears. I' guess I'll have to redo them to get those. The logs look good to my inexperienced eye. I asked the tuner for a conservative tune that would work well on a road track and could still take into the mountains on a hot summer day with the car loaded with junk. With that background: Air flow is moving around 232 g/sec max. and boost peaking around 17. KC looks great too, nothing really lower than a 4 with lots of 8's and 9's. So unless I'm reading this wrong my car looks pretty happy. Anybody with more experience care to comment?log1.pdflog2.pdflog3.pdf Link to comment Share on other sites More sharing options...

edmundu Posted December 11, 2006 Share Posted December 11, 2006 Logs look great! Plenty of DA, so the ecu is happy, and has a lot of rope for if it needs to yank timing. Strong MAf (v), very typical of Stg1, in those air temps. Logging your AFR will be meaningless, as the factory O2 is nowhere near accurate below 12:1. All you can expect to see is it bottomed out at 11.04-11.12 Link to comment Share on other sites More sharing options...

I may log the AFR again in the correct units just to make sure it's not anything crazy. I'm assuming I grabbed the correct AFR column right. There was more than one to choose from if I remember correctly. Link to comment Share on other sites More sharing options...
CasopoliS Posted December 11, 2006 Share Posted December 11, 2006 So did anyone with the LGT ever try putting a WB AFR 0-5 output on the fuel tank sensor wire to log with ecuExplorer???? Apparently they did this but it was on a WRX I think. The fuel level sensor is like 0.3 - 4.8 volts.... so you can log that voltage. If you tap in the 0-5 V output of the WB AFR you can log it just the same. I looked in the LGT ECU pinout and I do not see anything about this wire though. I am looking for a cheap easy way to log WB AFR as a function of RPM. Link to comment Share on other sites More sharing options...

lgt_nube Posted December 17, 2006 Share Posted December 17, 2006 Sorry if this has been answered in this long thread (I read the first and last page). My question is, does the LGT (mine's an 05) limit turbo boost based on Manifold Relative Pressure or Manifold Absolute Pressure? The difference would be felt in driving at high elevations where the Atmospheric Pressure is lower than at sea level. If the limit is based on Manifold Relative Pressure, then the Manifold Absolute Pressure (and power) would decrease with altitude. If the limit is based on Manifold Absolute Pressure, then Manifold Absolute Pressure and power should stay the same (at max boost) with increasing elevation - except for hp loss from higher air temps from more air comression, and there would be more turbo lag.

MarcusDubya77 Posted January 15, 2007 Share Posted January 15, 2007 WTF...I have been trying to use the ECU explorer software...Which is up to date and properly installed..I have all my cables plugged in..I go to my car plug in the OBD cable , turn the key 2 clicks...NOTHING!!! I see that the ECU disconnected..and I get this in the lower left.. Prolific USB-to-Serial COM Port [COM2] Invalid Port COM0 WTF, can anyone help me??? :woowoo:check out the Diamond Gray Metallic Monster!!! Link to comment Share on other sites More sharing options...
mickeyd2005 Posted January 15, 2007 Share Posted January 15, 2007 Which cable and which software versions are you using? If you're using AP V1.0 cable, did you select the correct serial port? Link to comment Share on other sites More sharing options...
MarcusDubya77 Posted January 15, 2007 Share Posted January 15, 2007 see. I am lost I can't figure out how to selct serial ports on the ECU software..it has configure comms, but nothing that designates specific comms ports :woowoo:check out the Diamond Gray Metallic Monster!!!

mickeyd2005 Posted January 15, 2007 Share Posted January 15, 2007 Isn't there a window in the lower left quadrant with all the serial ports? I'm at work right now, but if someone isn't able to help you by tonight or tomorrow, I'll try to do a screen capture. I normally use my tactrix cable, but I do have a Cobb V1.0 somewhere in my garage. Link to comment Share on other sites More sharing options...
MarcusDubya77 Posted January 15, 2007 Share Posted January 15, 2007 finally got it to work!! its F-in sweet..now I just got to figure out how to record the data!! :woowoo:check out the Diamond Gray Metallic Monster!!! Link to comment Share on other sites More sharing options...
mickeyd2005 Posted January 15, 2007 Share Posted January 15, 2007 Set your save subdirectory. Then in the main variable window, right click and then choose to make your defrost button your start and stop button. This will allow you to easily start your datalog with your defrost instead of having to click on the laptop. Link to comment Share on other sites More sharing options...
The Don Posted January 30, 2007 Share Posted January 30, 2007 Is there a working link for the DL1 program..i cant find it on here..and the ecuexplorer isnt working for me either..im going back out to try it again edit-- it will not connect to the ecu Port Assigned to Port description COM1 SSM Diagnostics Communications port Link to comment Share on other sites More sharing options...
wheatleya Posted February 1, 2007 Share Posted February 1, 2007 I see peoples logs with AFR's on them. I can't figure out which box to check for AFR, there is about 7 of them. And why can't I record data? I will have to read more:) Link to comment Share on other sites More sharing options...

Then plug in your adapter. After the drivers are installed, plug in your AP 1.0 cable and then fire up ecuexplorer 3.0.25. In the lower left corner, you should see the COM port that represents your USB->Serial adapter. Right click it and then select it. Exit ecuexplorer and then restart ecuexplorer. Here is a screen shot of my ecuexplorer, my adapter is COM11. If your computer has no serial ports, it might very well be that your adapter has chosen COM1 as your USB->serial adapter.

The Don Posted February 1, 2007 Share Posted February 1, 2007 Thanks Ill try this when i get outta school today. Update..tried it still isnt connecting to the ecu.. ive uninstalled/deleted the program well over 7 times now. tried another program called enginuity that didnt work for me either...i dont really know what else to try at this point..

NSFW Posted February 2, 2007 Share Posted February 2, 2007 IIRC, Enginuity will only log when the rear defogger is turned on. Been a while since I played with it though. Link to comment Share on other sites More sharing options...

Just cut and paste the STI throttle duty cycle maps into your existing map, reflash and be done... Link to comment Share on other sites More sharing options...
edmundu Posted February 24, 2007 Share Posted February 24, 2007 Why mess with tip-in? Just cut and paste the STI throttle duty cycle maps into your existing map, reflash and be done... He's not looking for throttle pedal adjustment. But rather actual fuel tip in, for when larger or non stock injectors are being used.... Link to comment Share on other sites More sharing options...
