AtlantaZ Posted September 14, 2011 Author Share Posted September 14, 2011 (edited) I tuned the map a little and am now showing 12.0:1 AFR at WOT and 150kPa (7psi boost). But it still acts like it's flat, and I'm willing to be that the plug tips look white. I'll try running Dave's AFR map and using his VE as a starting point, and see if I can't get those plug tips to a nice tan color.

AtlantaZ Posted September 14, 2011 Author Share Posted September 14, 2011 I also failed to mention that my WBO2 sensor is about 24" downstream of the turbo, so I definitely need to rework the VE Analyze lambda table to get accurate tuning. Does anyone have guidance on configuring the lambda table in Tunerstudio? Quote Link to comment Share on other sites More sharing options...
cygnusx1 Posted September 15, 2011 Share Posted September 15, 2011 (edited) Checked out the Datalog finally. So far I do see you running too lean for MY taste. I would stop screwing around with 14.7 in cruise and try 13.7 as your leanest areas. Then see how that feels. Second of all, I saw your coolant temp was in the 180 degF or more range, but the log showed that the car was still running in warmup mode. !? You also have AE set to 100% TPSdot and a threshold of 1000 %/s, which may never give you any AE at all.

AtlantaZ Posted September 15, 2011 Author Share Posted September 15, 2011 I just noticed the warmup issue myself! I was double checking my startup and warmup curves, and somehow I have a warmup curve that is enriching even at normal operating temperatures. Not sure how that happened, but I will definitely pull that down to zero enrichment at CLT>=160*F. And yes, I have AE turned off so I can focus on the base VE table. So far the transitional throttle response hasn't been a problem - I've just kept my throttle pedal movements gentle. Quote Link to comment Share on other sites More sharing options...
cygnusx1 Posted September 15, 2011 Share Posted September 15, 2011 (edited) I think you need to reduce the table temperature range to 160F to get it to come out of warmup mode. Also make sure you are getting good strong voltage to the coils when it's running. Edited September 15, 2011 by cygnusx1 Quote Link to comment Share on other sites More sharing options...
AtlantaZ Posted September 15, 2011 Author Share Posted September 15, 2011 What's the best way to check voltage to the coils during running, besides cutting a hole in the plug boot and poking it with a coat hanger? Quote Link to comment Share on other sites More sharing options...
cygnusx1 Posted September 15, 2011 Share Posted September 15, 2011 Not the spark voltage, the 12volt supply that charges the coils. Quote Link to comment Share on other sites More sharing options...
AtlantaZ Posted September 15, 2011 Author Share Posted September 15, 2011 (edited) Will do a continuity check on the EDIS-to-coilpack wires tonight. I'm also going to inspect the injector wiring, as I think I saw some exposed solder that may be grounding out on the aluminum heat shielding. I think coil voltage is good... otherwise I would expect to see darker/wet spark plugs. But I'll be checking all of the wiring in the fuel and ignition system over the next few days.

cygnusx1 Posted September 15, 2011 Share Posted September 15, 2011 Weird numbers on your VE table.... Your VE ranges from 2 to 150 or so. That just seems strange to me. Quote Link to comment Share on other sites More sharing options...
AtlantaZ Posted September 15, 2011 Author Share Posted September 15, 2011 Ignore anything past 150kPa or 4500RPM - untuned areas. Plugged in raw numbers from a borrowed map. Quote Link to comment Share on other sites More sharing options...
