i got the black box and the keyspan in the mail... i don't have any software or anything.. i haven't even plugged it into the computer.. whats the first step man? that thread told me nothin..

If you have the latest version of vista (or in my case the 64 bit) DHP will not load onto the computer, or you will have a hell of a time figuring it out because i know i couldn't do it. I just put it on a laptop with XP and the installation process was much simpler.

When you order, you get a couple of cables and a black box sent to you. There's a sheet of paper with some instructions, but no install disk (batteries not included, lol).

You then have to sign up at DHP's online support forum, where you can search to find the beginner's how-to thread. Here is where you download the actual software + all of the support software if you need it. A PDF manual is also available.

You're going to tell me that helped you with NOTHING? Thanks for your appreciation of the information I wrote down 3 years ago. Sorry I can't fly to MN to hold your hand with this. DHP software isn't easy to use. If your local members are willing to do it for you, great. Why waste everybody's time here?

Maybe i should have been more clear man.. I was getting REALLY aggravated with this damn tuner... I was basically only looking for a link to the installation file... i got a disc from someone.. and installed it.. as easy as that.. i have been scanning for the last 20 minutes.. what a fun tool....

Thanks for the help though.. if i have any other questions i always post here before going anywhere else..

Yep, that's always a good idea. If you don't tell us exactly what is wrong or what you need, you're not going to get the help you need.

Vista has been known to be a PITA for some DHP users, while others have had no problem. DHP "never" sold a tuner under the guise of being Vista friendly, exactly the opposite. Glad to hear you're up and running now.

Hmmm shoulda kept going past 2nd, cant really tell if thats false shift KR or not, although 4* is quite high for it to be false. If youre getting those kind of KR numbers in 1st, i would say youre running too small of a pulley unless you wanna throw all kinds of fuel at it. KR should show up in 2nd at the earliest IMO. You still have the 1.9/SSAC/3.15 setup? Did you put the GenV on?

gen v is not on yet
your correct on my mod list

Hmm do u have a 3.3 or 3.2 lying around? They might yield some better numbers until you can get the Gen V on. Again it would be more beneficial to see a scan all the way through 2nd and into 3rd as that's where the more serious KR occurs.

ya i have a 3.4 BUT i stripped the bolts on the hub so the 3.15 is stuck on there

Well i would be very careful on the throttle until you can get the Gen V on because 4* in 1st is pretty bad. I cant really say the best way to solve the KR in this case, but the safest thing would be to pull the timing so that the PCM doesnt have to work so hard to keep the pistons in tact. Otherwise you could try to pour some fuel in there to cool it down but its still iffy. I would be very cautious until the new blower goes on.

word
i have been doing WOT 10 times a day on this exact tune...
I still don't know how to "add fuel" or take a

http://www.scandepot.net/viewscan.php?pk=4776

Why after my 1-2 shift did it command 14.7:1 A/F when its set to command 11.2

Your LTFT's look like you're still running lean, since they should be 0 at WOT (and ideally all the time). On your first scan your O2s were in the 700s, way lower than than the 900s they should be in. Were you running E85?

your O2's are way too low at ~700.
i dont know much about tuning, but i would try adding in a lot more fuel, but i doubt that would help much.
You are close to maxing out your maf, so i assume you are going lq4 with the gen V?
next time you scan try getting a longer run in. the point isnt to just go wot from a stop. roll into the throttle and scan to at least 100mph (provided its a safe road).
mark at least these parameters: KR,rpm,O2,LTFT,mph,mafhz &TP%

No need to scan ign volts, but thottle % would be nice. Your scans will be higher res with fewer parameters scanned. STFT is sometimes needed, but probably not here. Boost can probably go away.

I agree, I've never seen 700 O2 values, and if I did I would be concerned. Is there E85 in the mix? Maybe could explain. Also LTFT should lock at 0 at WOT. Why are we not seeing as much KR in the 2nd scan? Did you change something? It's too bad there is no O2 here to look at.

No i was not using E85... I will do another scan tonight after work... with O2 one from 10-100mph

I just got some Nitto extreme street legal drag radials

Please post your full mod list.
Please scan for IPW in addition to what you already have. (it's in your first scan)
Please scan for MAP instead of "boost".
Please scan for TP%
Try to scan in 3rd gear or 2nd to 3rd. There is not enough load in 1st gear to make it count.

Your timing fluctuates quite a bit in that 2nd scan. I would like to see tp%.

O2s look better than before but ideally should be in the 900s (meaning you're still running lean) This can also be seen because your LTFTs are still above 0. What exactly have you been changing?
