Thread: HPTuners newb

where or how did all u guys learn to use HPTuners? Sites, books? Im a newb to tuning and would like to learn how to do all the tuning myself to best fit my needs.

I have HPTuners standard version but am planning on uprading to Pro version but before doing so i need to learn what everything means, does and how to do it? I have tried to do searching on the HPTuners site but its all foreign to me.

Please dont bash, all im asking for is help. All information on tuning will be greatly appreciated!

Thanks,
Colin

There is a GM V6 section of the HPT forum that was very helpful to me when I started tuning. And, somewhere on here and some of the other forums are some how-to's on where to get started. I can't remember where everything is, but plan on spending about 20+ hours just reading and re-reading information before you attempt to start tuning. It's easy to get started, but also easy to mess things up. Get familiar with the scanner software before you even bother to open up the editor.

When the time comes to start making adjustments, move in small steps. Every time you go through and make changes, save a new file. Don't just overwrite the old one. It's easier to step back if you mess up that way. Also, the number display resolution is adjustable. The default is whole numbers. I have mine set to show hundredths (x.xx instead of just x). Changes made can be more precise and are easier to smooth.

how do u guys know what settings should be at? like 02s at WOT?

o2's arent going to be the main thing youre looking at anyway. you want to watch these values mainly and a few others if need be:

boost
IPW
LTFT
STFT
KR
timing
o2 mV



start by lowering your timing down to about 12* at WOT and start with the pulley you want to run. start with fueling. make sure your fuel trims are close to zero and stay there all the time. then slowly increase timing until you get the car to get some KR, then back it off a little. your o2 values are only good as a reference to yourself to know if the car is running rich or lean, there are no exact sciences about the o2 readings (usually people shoot for .940 mV on a conservative tune, but .940 on one car could be .880 on another).

fueling > timing > boost

You did not adjust the VE table, or the MAF frequency?

Bio248 gives solid advice. To build on it, be aware that too much fuel is bad too. Running too rich causes a different set of problems, but it is a better start than too lean. The rule of thumb that I have seen is .930-.940 for a "standard" tune...that is to say no cam/intercooler/meth, etc. that would have the desire to pull fuel.

bah, forgot about that. yeah, do a VE and MAF tune before all that nonsense.

Anyone know the exact link for the Eddie's Table Modifier Thingy? I know it is somewhere on The Blattners Family Home Page, but cannot find it.

well, actually, i take my statement back. dialing in your fuel trims is VE and MAF tuning.

im in the same boat here ordering my tuner in a week I hope As it will tune my crown vic aswell as my gtp

The stuff is all foriegn but shouldnt be that hard after some serious reading

Table Modifier - The Scan Data Thingy

**** VE tuning. It takes a while to learn everything, just get comfortable taking scans and reading them. Then sit down and read all the tuner guides. It's easier if you have someone else locally that has hptuners to go through all the basic motions with you. You'll get comfortable after a year or so.

So your saying ... forget the VE? I didnt do it anyway

VE tuning will just allow your car to run well without a MAF. makes me wonder if anyone has ever switched to a speed density setup on our cars.

Speed density is a tempting concept, but I don't think we have everything available to make it work well.

i have more faith in a few of you than that. im sure we can make it work if we wanted to.

Maybe if I ever get everything in my car working properly at the same time, I'll be willing to try it.

I ran speed density for a quite a while last summer while doing my tuning.. also ran the remainder of the season in Open loop mode.. car was running great...

Having a wideband 02 is KEY when tuning!

If you have serious mods, don't cheap out, get a wideband, get a tuner.. do it yourself

Thanks for all the great info people. I will be sure to scan and scan and scan before i tackle the editor part of the program. I just need to figure out where things should be parameter wise so i know what i should be looking for. I just need to upgrade to the pro version so i can record and save my scans and see all the parameters that i cant see in the standard version

You are confused...the pro version does not change what parameters you can see.
