RomRaider

So I recently got a wrx with an unknown tune and chased every issue it had replaced with what I wanted an now I’m on to open source. definitely a noob I have no idea what I’m doing so I’m looking to have some one map it for me mods are and forgive me if I miss something
415 fuel pump 1000cc injectors full 3” catless cai I do have a turbo smart boost controller coming but it’s on back order still waiting on the OpenPort 2.0 cable but just wanna get my ducks more in a row

You're also going to need a wideband o2 sensor and a little more details about the injectors you've bought. Most will come with a flow sheet/latency info (if it didnt come as a print out with them check with the supplier it could be on their website somewhere).

Also what actual car/ecu do you have, pretty much anything that left the factory turbocharged has a fairly decent boost control setup from the factory - just add a 3port solenoid instead of an external boost controller and let the ECU sort out boost in the tune.

I have a aem wideband injectors are deatchwerks 1000cc I did get get a flow sheet

Will need the rom file from the vehicle for a start. And any modifications that have been don ro the vehicle to create a base map.

The openport2.0 cable should be in tomorrow I believe I have the appropriate files on my laptop to get a base map I’ll keep this updated as best I can

Ok so I feel like I got the car running pretty decent but now I’m wondering about tuning for octane cause I only have 91 around here
Appropriate maf scaling exhaust tuning and for when I get my 3 power boost controller. I just ned the just of everything and I can continue to play with it I would upload a log but Java has an issue with RomRaider

I don't see any mentioning of EGT.... it is a turbo setup, right?

On the original rom egt is disabled

Ok so you'll have to play with timing and AFR to make sure your car runs knock free on the lower quality fuel.


If you have an aftermarket maf tube then yes, log things like final fuel base AFR vs wideband AFR and adjust MAF scale until the 2 match up.


Start with a low value like 30% max duty, do a pull - see what you get and then start to increase duty on subsequent pulls. Adding the duty like this allows you to populate the entire wastegate duty table to hit your targets as you add throttle.


usual cause for this is you have 64bit java installed and romraider needs 32bit java to run properly.
