BSOD2600 Posted October 24, 2006 Share Posted October 24, 2006 I'm using Vikash's great program to monitor my ECU metrics. Since I'm unfamiliar with the various ranges of the parameters, would someone look them over and give some feedback? Unfortunately since I'm using a old rump roast laptop, the battery is dead so I can't drive around and monitor values. I did drive around town to get the car warmed up, then sat in the driveway idling. Idling: RPM 625-700 Coolant 192-203F Ignition Timing 15 Airflow 1.04-0.98v Load 39-42 Throttle PS 4.68 Injector PW 2.4-2.6ms IAC duty 0.365 O2 0.04-0.8v Fuel trim -1.56-2.56% Timing correction 0 Boost control 1.56% Bar pressure 663.75 torr Boost/Vac -18 inHg Reving: & holding to around 3-3.5K RPM Coolant Ignition Timing 47 Airflow 1.9v Load Throttle PS 4.2 Injector PW 2.1-2.3ms IAC duty 32.50% O2 Fuel trim 3.12% Timing correction Boost control 93% Bar pressure Boost/Vac 1) Is the O2 sensor ok? Seems kind of low, or would that change more while driving? 2) The barometric pressure was reading at 663.75 torr, which is 12.82 PSI. I'm at ~4300 ft. This limits by boost range a lot before the fuel cut could kick in, right? 3) How are the other values? Quote Link to comment Share on other sites More sharing options...
nipper Posted October 24, 2006 Share Posted October 24, 2006 everything looks fine. Revving doesnt really tell you anything, you really need to be under load. nipper Quote Link to comment Share on other sites More sharing options...
Virrdog Posted October 24, 2006 Share Posted October 24, 2006 There is a giant thread on the BC Legacy BBS that has all the correct ranges for the values and Vikash commenting on them. Quote Link to comment Share on other sites More sharing options...
Shep2112 Posted October 25, 2006 Share Posted October 25, 2006 You could probably pick up a power inverter for $25 or so, that will run your laptop just fine. It's useful for other stuff too, but it's an easy way to test out your car under load and all.. -Eric Quote Link to comment Share on other sites More sharing options...

Something about the sine wave not working with the transformer...I dunno...all I know is it doesn't work, I was dissapointed... Quote Link to comment Share on other sites More sharing options...

Ive been using an APC PNOTEAC75 for 4 weeks now that runs and charges my laptop. nipper Quote Link to comment Share on other sites More sharing options...
Shep2112 Posted November 3, 2006 Share Posted November 3, 2006 I don't know the APC unit. But at places like CompUSA, you can get adapters that will convert the 12VDC to whatever your laptop needs, without going to AC and then back to DC.. (perhaps that one does this?) That might make a smoother sine wave, generates less heat, etc.. Quote Link to comment Share on other sites More sharing options...
dome24 Posted November 3, 2006 Share Posted November 3, 2006 OTS but can i use this homemade scanner on my 97 Impreza? If not is there another one that i can? Thanks, id love to be able to look at my ecu without having to shell out $5k for a snap on scanner. Pete Quote Link to comment Share on other sites More sharing options...

Vikash's scanner only works with OBDI as I recall and cars after 95 are OBDII. Quote Link to comment Share on other sites More sharing options...
