I know that open source is more of a DIY solutions in terms of tuning. While I understand the basics and consider myself ''knowledgeable''. I don't feel 100% comfortable tuning the car myself w/ open source.
Any open source tuners out there?
Figured I'd ask here.
Trying to learn and figure out the cam timing tables. Any benefit from playing around with these on stock turbo?
I understand that typically the goal is to help spool bigger turbos...
Has anyone done an exhaust cutout to see if there are any measurable gains that could be had?
In order words, if by passing the OEM catback provided better spool and power gains with an aftermarket DP?
I've heard of a few IS20/IS38 guys doing exhaust cutouts and they mentioned gaining some...
For sure. Our gas is good.
But this also clearly shows that when both cars are using the same gas, not much of a difference between the EQT tune vs a custom ED tune (other than power up top)
Keep in mind that the EQT tune is for 93oct. The only thing the 94 is doing at this point is preventing...
True. It is better than US 93 and it usually contains anywhere from E09-E11.
(with a price to pay these days tho :oops:)
Still, you should see one of the OTS ED logs. It’s very basic…
It’s a starting file to improve upon.
Yes you would. The OTS ED files are pretty bad. Similar to the Cobb OTS files (maybe not as bad) but they lack refinement. Think of the ED OTS tune as a base file before you start doing revisions with an actual tuner.
I disagree. Even on pump gas there are some decent gains to be had from a...
Pretty much neck and neck. Wouldn’t say I clearly won tho.
Buddy of mine Joe. Also got help from various plp (such as Moose, Diggs, Railroader, etc.)
I did some fine tweaking after I understood the basics.
DSG (EQT TCU tuned)
Ran a buddies GTI stg2 EQT on pump (most recent 93oct file v2.52). Pretty close race which surprised me since the GTI is lighter than the A3.
We both did a log separately on the same road (so the conditions were the same). Here are Vdyno numbers just for fun (obviously take these with a grain...
Not saying it's not possible. Clearly your dyno sheet shows it! Unfortunately those numbers don't mean much without a baseline. Also, IS20 cars usually have peak TQ around 3500-3700rpm and then it starts dropping off.
How did you determine that the charge pipes / catback exhaust made a 20whp gain?
