OFT Tune Usefull Information and Tweaks

[Riftur]

My 2013 A/T is completely stock except a drop in K&N filter. I run 93 octane and am looking for a bit more 0-60 speed. Is it possible to safely do with the OFT or do I need to change the diff gears?

[guybo]

Is this a troll or real?

This rom code appears similarar to other late model 32 bit senso subaru ecu like forester XV ect

The tip in is an extra firing of injectors so its just a pulse width ( info in the table properties in romraider)
Yes you can populate those tables i added some extra tip in in 2000-3000 rpm area

Sometimes their are duplicated tables because all this stuff is reverse engineered and it appears that the code complier sometimes puts two or more copies of same table in rom like the closed loop fueling tables A and B.

But sometimes like cranking IPW tables the Ato G tables have different function in the cranking sequence, we rely on the skills of the romraider guys to reverse enginneer these table functions

it appears that those tip in coolant tables are same but no guarantees,, again read the disclaimer at the start of xml romtaider defs

hello,

i know im firing up an old thread, but how do you know where the 2k-3k rpm area is in the tip in table? sorry, im a noob!

Make sure your fueling and maf scaling is good


Id probably try adding a bit more retard in the transient ignition retard tables if you getting knock on throttle transients. try whats in the 2017 roms


the tip in tables had little effect on knock reduction for me


see below for transient retard tables

When using the OFT for tuning and on a dyno, what's the best procedure after loading a tune and before making a power pull?

Prime your fuel trims. Make several slow (as slow as you can without feeling unstable) climbs to 5500rpm. I usually do this in 3rd or 4th. Once your LTFT has stabilized, and if your IAM is still at 1, let 'er rip.

I have had trouble with mine to. The launch control does not work on the 2017 and it took so long to get my maps I got them off this sight before Shiv ever got back to me. Whats going on maybe I can help?

In my case, I'm currently running OFT Stage 2+ tune that I got from Shiv.

Some time after installing Perrin inlet hose, I noticed a dent in the tube on the stock intake box (#17701), and instead of getting it replaced for $90 I figure why not just get the Perrin cold air intake (the regular one, not the 3" big MAF) for $280. I don't mind spending the money, and I already have the Perrin inlet hose anyway.

But I want to ensure I don't have any loss. I know a lot of people saying "don't use CAI, its pointless, it sucks for daily - only good for track, stock box with dropin is better, CAI too restrictive, etc" - but if apparently if you tune it with the proper MAF scaling it can come out on top? That's what I would like to do. Plus it cleans the engine bay up a lot by removing the air resonator, snorkel, and probably also drops a couple grams of weight. So I gotta learn how to do MAF scaling, or else I gotta get a custom tune.

I'd check with @shiv. I had the Injen intake and I was told the Stage 2 91 should be fine with that intake. I believe they cover a few better known intakes if not the majority.

[Breadman]

dumb question but i that all of these are 91, is there a reason for that? it would be nice to have a 93 map

[guybo]

I run the Stage 2 93 Octane EL map with an Injen (1st Gen) intake. Fuel trims are great, AFR is great (maybe a bit fat, but I think the tune is conservative). I've modified the setup a little for better intake temps, and I am very happy with this. The 93 tune is solid, if you can find 93 in your area.

v3 are all 91 and id assume that the v4 would be the same
