First steps with Tactrix OP2?

Hi hoiw are you?

RomRaider doesn't read ECU images from or write them to the car. You need to use EcuFlash for that.

IMO this is what I always do:

 

First step = save a copy of your stock ROM in at least 2 places just in case.

 

Second step = datalog a 3rd gear pull after checking IAM to see if it's at 1.000

 

Third step = Pull a learning view using the LV tool from http://www.romraider.com to check fuel trims and any stored knock events causing timing to be pulled.

 

If everything is good, (fuel trims +/- 5%, no stored knock in the LV, and IAM 1.000) I will start tuning and turning the wick up on the boost. I usually only go in 1 psi increments just in case I start to run into knock. Slow and steady is always the best approach to tuning. I usually flatten the knock correction advance table to 6 or 7 (while taking the corresponding amount of timing out of the base timing table) to make knock detection and tuning easier.

 

I also check to make sure target boost is being achieved. On almost every subaru I've tuned from stock, it was not hitting peak target boost in stock form. If not I make sure to adjust wgdc tables to hit stock boost targets and then turn up the wick from there. The stock tables usually have a slow ramp up to peak boost at about 3500-3800 rpm. I always aim for peak boost ASAP for the car to make the most power.
