Who is running this. Im getting ready to start building my 02 wrx. I already have megasquirt II v2. so its pretty simple on nissans. But im starting out with this subaru just wondering if anyone is running one. maybe can help me out with a base map. to start off and just get it started. here is the setup i will be running.

02 wrx:
ej205
wiseco pistons

Why not just go open source? The stock ECU on these are pretty sophisticated...

I doubt you'll get much help. Very few people run megasquirts in the Subaru world. Open source is normally the way to go and if that's not enough most opt for an AEM or Hydra standalone.

Megasquirt is awesome. It can be extremely powerful and take in an amazing amount of data.
For your setup the cost of adapting Megasquirt would be several times the cost of buying a cable, assuming you have a laptop, which is all you need to start OS tuning yourself. More importantly, the ECU will provide you with all the data needed to tune a basic setup. You'll also have access to a lot more support from the community, which isn't huge, as most people just get an accessport.


OT, I see you've got an S14... I had a black on black leather 95 SE for a long time, great car.

i used to have a rb25 240 ended up having to sell for the kid and the only reason i dont see going open source is because i dont completely understand the system like i do with megasquirt with megasquirt i can go with a 2 step lauch antilag run all my extra outputs tune real time and so much more. there system is very understandable and it tells you exactly what everything in settings does thru there manual and how you would get your calculation.

But if anyone will help me learn open source i am not putting it out of the way I wouldnt mind learning it i have already downloaded the programs and have a vagcom cable also.

my setup is pretty simple id say
1000cc injectors
tdo5-20g
wiseco pistons

For an 02 WRX ECU (16-bit), if you only plan on these mods (and mods are addictive), Cobb accessport is about the same price range as a PNP Microsquirt (so DIYtune.com says) but Cobb has more support behind it. I've been using open-source for a while now, and it's okay, but not as option-rich and friendly as i've seen in Megasquirt or even Cobb. True, the Subaru ECU is pretty complex, but preference would go to Cobb if I wasn't so cheap

If plan on doing exotic like closed-loop WB tuning with flex fuel in the future, you might want to lean towards Hydra ($$$) or Megasquirt.

The bottom line is if you understand terms like VE, MAP, MAF, and Alpha-N in Megasquirt, then stick to what you know and welcome to NASIOC!

Just my two cents

Just exactly what options do you NOT have with open source, that you get with an Accessport? A pretty screen that shows you a useless amount of data? You still can't do anything with your log data without a computer.

map switching is the only real advantage to the AP. I wasnt asking about the MS. AP doesnt offer anti-lag, nor (that I'm aware of... certainly not for the 02-07 crowd) does it directly support flex fuel.

AP does not support Anti-lag. It has a fuel cut launch control... two COMPLETELY different things, and you have that option with OS too.
