KGreb Posted December 23, 2005 Share Posted December 23, 2005 There are some alpha stage programs available for the Tactrix cable that support flashing of the older '02-'05 2.0L WRX ecus. Check out openecu.org for more info. The 2.5L STI/FXT/LGT ecus are planned for future development. Link to comment Share on other sites More sharing options...

lookslikeanevo Posted January 5, 2006 Share Posted January 5, 2006 so is the 1.2 a direct obdII to usb? and man it would really be sick if Current:MY05 SWP wagon - 253/290 UP, AEM CAI, Invidia Q300, tuned@yimisport OLD: MY06 GRP - 274/314 Link to comment Share on other sites More sharing options...
KGreb Posted January 5, 2006 Share Posted January 5, 2006 The openport cables have an OBD-2 hood on one side and a USB plug on the other. Very compact compared to some other solutions. Link to comment Share on other sites More sharing options...

KGreb Posted January 10, 2006 Share Posted January 10, 2006 Dynamic advance multiplier and engine load are under the "User-Defined Data Items" section in the left pane. Once you select them, they will appear with the other items in the main pane. BTW, you probably want to look at manifold relative pressure (ie boost), not absolute pressure (boost+atmospheric pressure). Link to comment Share on other sites More sharing options...

KGreb Posted January 10, 2006 Share Posted January 10, 2006 What do all the various engine load #s give you when you select them? Or can anyone point me to the engine load documentation? Load is apparently calculated in grams of air per cylinder. It is used as one of the axis in many tuning/remapping programs. Load can also be used to estimate torque, just as MAF can be used to estimate horsepower. PDX posted a good example with charts and logs when they tried an 18G turbo on the LGT.

scans007 Posted January 11, 2006 Share Posted January 11, 2006 I do, I have cobb's WRX one with a perrin sleeve (Closest to stock air flow you can get). But it was tuned for it....so the neg knock that hight shouldn't be there...... correct?

Try putting the stock intake back on and taking a log, that will tell you if that's the cause. Double Award Winning Legacy GT Wagon Link to comment Share on other sites More sharing options...

You were not at WOT, as shown by the throttle opening values of 21%-12%. In fact you were letting off the throttle, so under light throttle and certainly when you let off, you should expect to see major advanced timing in the 30's-40's, along with negative KC values! Without showing us some WOT pulls, you honestly cannot accurately ascertain the current state of your tune. So show us some more logs! Or if you don't want to post them, you can pm me.

scans007 Posted January 12, 2006 Share Posted January 12, 2006 Yeah I know, but still -7 is nothing to be happy about....even if I was off the acc. I know it's way less dangerous by talk'n to the tuner........I didn't wanna post the whole log due to the fact that it's really giving away his trade secrets and stuff, just be'n respectful to his wishes...if he allows me to post them at somepoint I will.....

LEGGTLTD Posted January 19, 2006 Share Posted January 19, 2006 For ECU Explorer do you configuer the Comm settings once you connect it to the car? I just download it last night and it doesn't seem that you can change the Comm settings. So I'm assuming once I connect it to the car it will either simply establish the connection or I will then be able to change the settings. I'll be using a USB to Serial cable if that matters.

KGreb Posted January 19, 2006 Share Posted January 19, 2006 LEGGTLTD, with the current version I can change the comm settings (timings) while disconnected from a vehicle. It's under Options->Configure Comm Settings. If you are referrring to changing a specific COM port to be used, that is autodetected on startup. Just select the correct COM port listed in the bottom left hand pane. Link to comment Share on other sites More sharing options...

In the lower left hand pane it only listed one and it displayed nto available or some similar message.

Hopefully it will allow me to change it once I actually connect it to the car Some USB->serial adapters don't actually show up as a COM port to Windows until a USB device is plugged in. Try doing this before starting the program so that it can autodetect COMs properly on startup. Link to comment Share on other sites More sharing options...
