Soooo, yeah.... Is it an absolute must have for anybody modifying our engines? I would love to spend the 500-700 bucks on something else. Do performance shops typically have set ups where they can dyno & modify your settings all at once, thereby eliminating the need for this pricey little computer? Or will additional tuning be required even after a good tune in? I'm sure it certainly helps with trouble shooting.....hmmm...

Yeah, I guess I totally just answered my own question...damn it....

Well I'm still pretty much fully stock now.....so here's my other question, I'm going to buy this HPtuners module and at first I'm not going to feel like I'm getting much out of it until later down the road when I add a FMS and/or turbo, but....can you do fun things right off the bat with these things on a stock engine?


I like cold women and hot beer....errrr wait

Some places that dyno have hptuners and can tune your car for you but thats only good as long as you dont modify things again. Hptuners gives you full control of your ecu pretty much. You can adjust all kinds of things, like the temps your fans go on, shift points, trans line pressures, check/delete trouble codes, etc

if you like performance its a necessity STOCK. tuning that is... not necessarily hp tuners per say.

Well, yeah that all sounds pretty good actually.... actually I just need to get my radiator fan to work period! lol Somehow it made it through the summer only going slightly over temp, but as you know the fan not kicking on is a common problem with the early 2000 j cars. It runs when I turn on the A/C so I spent most of my summer with that on...which was fine.

Okay...so on the adjusting trans line pressure.......does this enhance or replace the auto trans or B&M shift kit?

What kind of stock and N/A settings are some of you guys modifying to pull a little more pep outta your LS6/LN2's? (is it LS6? idk I don't have one, just an LN2).

Is it applicable to adjust AFR in n/a set ups? and on stock fuel injectors? What about after adding new injectors and a FMS? Can you get some power gains by adjusting AFR in n/a set ups?


I like cold women and hot beer....errrr wait

On the stock tune the cooling fan doesn't turn till 224 degrees so its fairly common for it not to turn on all the time. And HP tuners is not for everyone. If you dont have any clue what your doing you can screw things up in a hurry. I have read page after page on this site, HP tuners site, erotic forum etc also bought a book from Greg banish and still don't know everything about it. So its not for your everyday person by no means. But research first before you buy and start changing stuff for sure.

Wow major typo lol. Ment ecotec forum not erotic lol. Damn auto correct on my phone powned me.

That damned auto correct is an evil bastard

erotic! lol....I didn't even realize you meant ecotec when I read that first post. I was like....ugh...I'm at work, maybe I shouldn't be exploring that site just now....lol

Yeah, I'm not a total idiot and I'm not looking to make drastic adjustment, so I should be able to operate an HPtuner module lol. I'm mechanically and technically incline enough to do well, plus I'm a spounge when it comes to information, and I've got an insatiable hunger to learn and read more about tuning. Plus..I always have the help of my buddy whos a level 4 cummins diesel mechanic on hand!!

For me it's not so much the not know how or what to tune, I can learn more and gain competancy with a tuning module. It was the cost that's really set me back. But since I'll be installing turbo support in phases I'll have to tune new components in every 5 or 6 months, it just makes sense to have it I've decided. I'll have the car professionally tuned once I start boosting though.


I like cold women and hot beer....errrr wait

It takes a bit of a learning curve but isnt so bad when once you get used to it. To adjust your AFR via the VE tables in hptuners you will need to learn how to data log with a wideband and histograms which means you will need to drop the cash for a wideband too. Thats just for AFR though, there are many other features. Adjusting the AFR helps boosted or N/A, the factory tunes for emissions not power.

yeah I get ya, I've been reading the HPtuners sticky about logging data from the wideband and histograms. I've got all the parts I need to do my exhaust next. I'm going from a set of weapon-r headers, flange from 2-1/4" there to 2.5" through a high flow cat, 21" resonator and back to my Kool Vue 2.5" muffler. Then in the spring I'l pick up the HPtuner module and wideband, and do my FMS in the summer. That should give me enough to play with I'm welding the exhaust together next weekend. weeeeeee. I can't wait this is going to be fun!


I like cold women and hot beer....errrr wait

concerning brands of widebands, are there any that people would suggest, I'm putting together a spreadsheet for parts, and I've found this place "innovative motorsports" they look ledgit. Any other suggestions?


I like cold women and hot beer....errrr wait

Innovate is really the best wideband you can buy in the "cheap segment" much better than the AEM. Sure the AEM is easier to setup when you first get it but literally the innovate takes 5 extra minutes for calibrating the sensor. AND if you ever need to replace your actual sensor you can actually do it with the innovate, with AEM it wont be accurate if you replace just the sensor (only the factory can calibrate an AEM wideband controller).

I have an innovate but if I could do it again id get an aem. They are supposedly easier to work with and don't have voltage offset issues with hptuners.

sweet, good to know. Now these things don't plug right directly into where the O2 sensor goes or do they? Do the analog AEM widebands interface with the PCM or is it simply a visual interface that reflects to the user what effect the changes are having that he sets with HPtuners?


I like cold women and hot beer....errrr wait

You should retain the stock narrow band o2 sensor. The Wideband should optimally be put 18" from the head. You can either run the output into the hp tuners pro interface or if you dont like spending money you dont have to you can run the wideband signal in on the a/c pressure line and write a custom pid so that hp tuners can understand that signal is the wideband. Oh course if you do it this way you can't run your a/c when you're logging.

Don't like spending money? you mean the HPtuners pro interface? Yeah I'm all in on that one, the hell with the money. lol

Actually Thats what the resistor on the aem unit is for. All you have to do is swap sensors now.

Yeah but when you change sensors that required value for that resistor should change.
