SD Blending, LC/FFS, & CEL Flashing: 05 USDM STI A2ZJB11J

I'm getting ready to try this out on my system, just had a couple of questions.

1) The engine displacement table claims to be in units of cc, yet the default value is 2.46. Should I be entering 2500cc or 2.5L in this table? My guess is the units are actually L and the value should be more or less left alone.
2) What is the difference between the NSFW "Fuel Cut (Redline)" and the OEM "Rev Limit (Fuel Cut)" tables?
3) What is the Speed Density Constant used for?

Thanks

cc is a typo, should read in liters.. will get that fixed in the next revision.

The OEM rev limiter is non-functional in these patches, LC limiters override them. Enjoy!

Perfect, thanks

Jesus Christ on roller skates...

One iteration...ONE...and it's already running smoother and more consistent at cruise, spool, and WOT than it ever did on the 86mm blow-through MAF. It's not like it was running bad on the MAF either, perfectly driveable, just a bit lean at heavy throttle and low RPM due to throttle position-dependent MAF error. It's a little lean at idle on SD, but I'm sure that'll be taken care of in the second iteration of the tune.

This is nuts...why did we ever use MAFs again?

You can expect quite the donation in the coming weeks as I get this dialed in. Keep up the good work.

Glad to hear it's working out!

I will be rolling out some more patches soon including definition updates for released roms. The update includes the "engine load smoothing" factor which can help pure SD idle/CL driveability.

great job guys
very impressive.
I'll definitely donate a generous amount for my appreciation of your hard work if I ever put this to use

Question for MERP or anyone else who knows:

04 USDM STi: Can I purchase and use the CEL flashing mod w/o going to SD?

Will probably eventually go to SD; just not ready yet....

CEL Flashing roms all include Speed Density, but you can simply leave it disabled and run on MAF if you like.

04 STi is in the works.

I just wanted to thank you for your work! My car has never felt smoother.
I hope my contribution goes to some good beer's.
Thanks again!

Would you be able to add the flashing CEL patch to a different ROM ID? I run the same ROM ID as NSFW, A2WC522N.

Will the "Engine Load Comensation (MP)" that I already have mapped out on my current (MAF) ROM affect the SD/volumetric efficiency values if I copy and paste it over?

Is this patch compatable with the A2ZJB10J 05 sti ecu? If not, any plans for supporting it?

Thanks!

Just upgrade to B11J and copy your table values over. You can flash a B11J ROM on an ECU currently running B10J without a problem.

Sorry it took a bit longer than I said, other things came up and frankly I forgot...(the 05 is not my daily)

I hope my donation is enough to keep you motivated to continue your contributions in this area. Your efforts are not being ignored.
