Default Reflash questions from a newb...

Hey guys...i'm new to the Subaru scene, (haven't picked one up yet actually) but it'll be an 04 or 05 WRX and coming from the Volkswagen world where reflashes are common amongst 1.8T owners...I figured it would be just the same or similar to flashing a program to a Subaru ECU.

But after reading as many posts as I could...it seems as if I get the ECU flashed by a specific vendor...and then create my own fuel/timing maps via the COM port and essentially tune it myself? Please let me know if i'm a bit off of my hinges...thats my interpretation so far anyway.

I'm basically going to be looking for a one time reflash...i'm very good with the hardware aspect of cars and have built many motors in my time, but haven't gotten into engine management tuning too much so i'd rather just load a program and go with it. Any suggestions or links? Thanks!

For the VW's I have seen you have to send the ECU off or go to a shop that does the flash for you, but it's pretty much the same, just with different hardware.

You can get opensource maps for your applications and flash them using a cable from Tactrix and a few pieces of software, namely, ECUFlash. There are several programs for altering the maps, Enginuity is the most common.

I would start out at http://www.openecu.org/index.php?title=Main_Page and http://www.enginuity.org/.

Most of the time, someone in your area will already have the stuff to flash your ECU. I flash cars quite often for people in my area.

Hey dude...thanks for the reply! In the VW world, MK3's (93-99) you would send out the ecu to have the chip physically placed in the ecu...but on the 99.5+ 1.8t's etc...you would have to physically drive the car to an APR, Revo etc.. dealer and they would plug your car into their computer and flash their program onto the ecu.

Correct me if i'm wrong, but the companies such as Cobb Tuning or Vishnu do not have dealers set up to perform these reflash upgrades? Or is your method the way of getting around paying for the specific vendors software program? But you have to buy a specific cable such as the Tactrix cable that interfaces with the OBD port and a laptop?

Cobb has "ProTuners" but you need the $700 AccessPort to begin with. There are normally shops in your area that will do OpenECU or even Ecutek that you do not need another peice of hardware for. I myself recomend OpenECU using Enginuity and ECU Flash. that way you can be tuned by a pro-tuner or you can tune it yourself.

I really would love to tune the car myself...but like i said...i'm not too good with computer programing and get frustrated rather easily with that sort of thing. I guess i would have to meet a local on here and hopefully they would have the capability to write a map to the ecu for a bit more performance. I won't spend the $700 for this piece of hardware you mention from Cobb...so i guess this is going to be my only route.

Is there a sticky or anything like that in this particular forum for people to collaborate and perform flashes on the local level?

Thanks a lot guys for the informative responses!

first thing you should do is hit the local forums on this site. and fill out your Chapter/Reigon in your profile. so we know where your from and what kind of car you have.
