This sounds terrible.

Is there anything similar to HPT for Subarus? I?d love to tune the car myself instead of paying someone for a protune.

Why doesn?t HPT support the FA20 WRX? There?s STi support but nothing for the WRX? That?s lame.

I tuned my old GM car 15 years ago using HPT and it?s still running great today with 160,000 hard...

I swear, some 07's have a wacky computer-controlled boost limit that is unable to be tuned out. Mine never sees over stock max psi levels with a 3" pulley unless it's close to 0 degrees F ambient. If...

Hell yeah. I was wondering WTF was wrong with this thing.

Thanks!

That was my first guess as well.

Nice, thanks for the help. I didn't notice this thread was still alive, ha.

Here's my H.O. table now. A little ballsier than most, but meh.

The only time I've seen that light come on is when I powershifted my car from 2nd to 3rd on the highway (without the WOT box).

It doesn't listen to what you tell it to do. If it were my kid, I...

My dad's 02 Trailblazer is having an issue with it's a/c system. When switched on, the compressor clicks on and off continuously (and within 5 seconds of each other), and the vents blow hot air. When...

Do these cars take a certain amount of time to re-learn certain paramaters after reflashing the VCM several times?

I smoothed out a stock timing table, and when I loaded it and drove around, the...

This "stage II retune" from the repository looks pretty good as well, although I don't like how it has so much up top. Either way I have to make changes so maybe I'll start with that, seeing as how I...

Scratch that, I think this stock 07 timing table looks better.

Thoughts?

Thanks. I was certain that it should be smooth, that's why when I saw it I panicked. Smoothing it out (from what it was) has seemed to help during light/moderate throttle, but under heavy load it's...

Numbers-wise. I had my car re-flashed by a reputable tuner a few years ago, but have since then picked up HPT and began making changes to the car myself.

One thing I can't seem to get right is a...

I'm thinking about picking up a set of 80's and running E85 myself. There's a station 2 miles up the road from me that carries it, and a bunch of new stations are beginning to carry it as well.

Tune the MAF and then re-enable the VE if you're having drivability issues.

On my 07, 42# 3" M62-powered car, I am using a MAF-only tune and I couldn't be happier.

This is wack.

That is weird. What does your tune look like?

I looked at it and it looks fucked up. It shouldn't be bouncing all over like that with the car off, at least mine doesn't.

What wire did you tap into again?

You're not outputting narrowband readings, are you?

Still pretty dumb, IMO.

Better?

x2, lol. I am a complete noob to tuning, don't get me wrong, but some of the questions you have asked are starting to make me wonder if you should be tuning your car in the first place. No offense....

USE QUICK DISCONNECTS.

I don't understand why you would want to use a switch in the first place. It's more of a PITA to install and if it fails you won't know so you could end up with a tune based...

You can turn the fans off with the a/c settings in HPT.

Sounds legit. Thanks!

Does anyone leave this setting, found under engine -> airflow ->dynamic airflow ->high RPM disable, disabled throughout the entire RPM range?

I noticed during some logs tonight (I'm tuning my...
