bmx045 Posted March 30, 2012 Share Posted March 30, 2012 that last log looks good, 3.7 loads are similar to my 20g/tmic setup Link to comment Share on other sites More sharing options...
Strizzy Posted March 30, 2012 Author Share Posted March 30, 2012 Whoops. That last one wasn't a WOT run. I replaced it with the intended one. My bad luck build Link to comment Share on other sites More sharing options...
bmx045 Posted March 30, 2012 Share Posted March 30, 2012 still that last one looks good but you might be maxing your maf out soon? Link to comment Share on other sites More sharing options...
Strizzy Posted March 30, 2012 Author Share Posted March 30, 2012 (edited) Which is why the first three are with my new larger intake. I should probably mention that my rev limit is set at 7500 and I haven't been able to get a log up to it. That last log just so happen to cut out after 6200 RPMs, even though I ran to at least 7k.

Strizzy Posted March 30, 2012 Author Share Posted March 30, 2012 I might try hardwiring my tactrix to the OBD today and try that, just to take a possible bad connection out of the equation. Someone also recommend I try using a power inverter and plug my laptop into it while logging, as that's the only way they are able to log their STI.

drkknight99 Posted March 30, 2012 Share Posted March 30, 2012 Meth may be in my future. But I already have the upgraded fueling parts available to me for cheap. If I can find gas stations in the area that have unleaded 100 (or higher) I would actually consider DDing on race gas. A speedway a few blocks from me has 114 for 4.99/gal but it's leaded (they don't know the price is set wrong )   It was low voltage going to the chassis and the ECU should be protected from that kind of stuff. And there would be other problems too.   I wasn't having any other issues before, so I have a hard time believing my map is the issue. Especially since I'll get a random full log. Just some dumb suggestions to check from me that's all, after seeing your car at the shop, and what the guys there were telling me Link to comment Share on other sites More sharing options...
Strizzy Posted March 30, 2012 Author Share Posted March 30, 2012 I sort of remember have some minor logging issues while I was stage 2, but not as bad as it is now. That was way before anything was really modified. I'm pretty sure it's some crazy electrical interference/noise, and I just need to figure out a way to figure it out. It looks like I may be able to make something to block out the interference when logging though. I'll have to do a little more research before building it and plugging it in.

Mega Users seabass07 Posted March 30, 2012 Mega Users Share Posted March 30, 2012 I was hoping you had it fixed. I had some hope for my logging issues, which are identical to yours. That shit's driving me crazy! Link to comment Share on other sites More sharing options...
Strizzy Posted March 30, 2012 Author Share Posted March 30, 2012 From doing a LOT of reading, it seems Subaru didn't quite follow the OBD pinout specifications. Pin4, of the OBD port/Data Link Connector is supposed to be a chassis ground, and Pin5 should be a SIGNAL ground. From what I've read, Subaru has Pin4 and 5 both grounded to the chassis. I'm assuming the signal ground is supposed from the ECU? My bad luck build Link to comment Share on other sites More sharing options...
WhiskeyTango Posted March 30, 2012 Share Posted March 30, 2012 Someone also recommend I try using a power inverter and plug my laptop into it while logging, as that's the only way they are able to log their STI. I have one if you need it. Link to comment Share on other sites More sharing options...
Mega Users seabass07 Posted March 30, 2012 Mega Users Share Posted March 30, 2012 I have a cig lighter plug for my laptop. I haven't tried logging with it plugged in. I don't see how it could fix it, but it's worth a shot. Link to comment Share on other sites More sharing options...
Strizzy Posted March 30, 2012 Author Share Posted March 30, 2012 I have one if you need it. Thanks. I'll let you know if I can't find mine. I saw it a couple weeks ago, but I forget where  I have a cig lighter plug for my laptop. I haven't tried logging with it plugged in. I don't see how it could fix it, but it's worth a shot. Take the laptop battery out when it's plugged in. Apparently it help reduce electrical noise by making sure the laptop is grounded with the car.

Strizzy Posted March 30, 2012 Author Share Posted March 30, 2012 I'm also thinking of using a connecting a small capacitor between Pin7 and Pin5. Pin7 is the SSM signal (K-line), and Pin5 should be the SSM signal ground, as required for OBD. Hopefully this will reduce/remove any unwanted high frequency noise. I just need to figure out what size capacitor to use. It's been a while since my EET classes. My bad luck build Link to comment Share on other sites More sharing options...
Strizzy Posted March 31, 2012 Author Share Posted March 31, 2012 I added a 0.1μF capacitor between OBD pin5 and pin7. I can now log my first full after plugging in the Tactrix and starting RR. My second pull cuts out. But this time, my second logs shows timing being pulled. It almost seems as if before FBKC goes back to 0, the logger cuts. Also, on my last log, it shows me as not being 100% on the throttle, but I'm pretty damn sure I didn't let off at all. New logs attached.romraiderlog_20120330_192856.csvromraiderlog_20120330_193036.csvromraiderlog_20120330_195228.csvromraiderlog_20120330_195520.csv My bad luck build Link to comment Share on other sites More sharing options...
bmx045 Posted March 31, 2012 Share Posted March 31, 2012 im finding the same throttle thing happening to hicksta, it reads less than 100% throttle but takes a while to read 100.....even when wot Link to comment Share on other sites More sharing options...

fahr_side Posted April 2, 2012 Share Posted April 2, 2012 Have you guys tried different cables? This. I was having intermittent problems and then went to a new cable with a choke on it. No problems at all logging now, zero.

Strizzy Posted April 2, 2012 Author Share Posted April 2, 2012 I tried 6 different OP2, 4 laptops, multiple USB cables, and pretty much anything else you can think of. My current USB cable even has 5 chokes. My bad luck build Link to comment Share on other sites More sharing options...
