Topic: New to HP Tuners World!

[MyBigToy]

Well, I finally found a deal on HPT. I just bought Loggie's from TOS. Now the fun begins! I have a feeling I'll be pestering a couple of members around here while I'm learning. (cough, Main One, cough KYBob)

[bluedevil]

I saw the thread and thought about you but didnt see your name on the list of items sold.


Good for you Joe,...have fun

I've thought about it also but with Monte getting my fans running through the Predator, I've shelved the idea for now.  Good luck with it.

I've had some hard thoughts on this too.  It really POes me that DS doesn't support uprades a little cheaper......

OBB, did you let him tune you up yet??    Sorry!

I would really like to log with HPT and see what the Av is really doing.....

[Main One]

Do a log and look at a histogram of LTFTs against MAP and RPM.  I think one comes as an example, if Loggie didn't redefine it, it would be #3.

I look to get mine between +0.5 and -4.5.

Good luck with learning HPT!!  As we talked yesterday, I'll see how long I can go with the Service Engine Soon light on!!  Thanks again for hooking up your Predator and reading my error code (crank shaft relearn)

   Thanks Joe!!!!

I just bought the software on Saturday morning and doubt Loggie has shipped it yet. I'll also have to buy a new laptop since the ones we have are so old they don't even have curent USB ports on them. We've been looking for an excuse to buy a new laptop since before Christmas.

LOL I've got the opposite laptop problem.  My HPTuners interface is so old that it doesn't have a USB port - it has a serial port which the newer laptops often don't have any more.  I have to run it through a port replicator.

Got an interesting story regarding a serial cable going bad and disabling Murman's AV along a Kentucky highway during his going away gtg........

It seems that I remember something about that, like the hour we spend on the side of the road rewriting his computer. 

OK, maybe it wasn't an hour but it was a while.

Bob, I think it was more like 2 hours.  Of course at first it was just me and Murman.......

I was trying to downplay the issue.

Yeah, until we got that other serial cable and got the truck running again, Tammy was not a happy camper.

That's the problem with trying to do things when you're miles away from home. I've been reluctant to flash my Predator when anywhere except in the driveway. I've never had an issue with it but there' s always the first time.

I agree...ME TOO!  I have a predator flashing checklist I go through!!

Now why would you two want to be "flashing" your predators? They don't have eyes to see anything  


Just had to do that.

I was just trying to scare it into submission so that it didn't lock up when it was uploading the updates!

Hurry and get real good at it so you can help me go over mine again.

I'm up & running!

I licensed the Av last night and flashed the entire Predator-modified tune into HPTuners. I spent about 3 hours looking around at all of the tables, graphs, etc. Man, is there a lot to learn. Now I have to start learning how to log and start the VE tuning. I really prefer to have someone with me the first time for moral support if for no other reason. I did a bunch of reading @ the HPTuners forum and on PT.net last night as well. I guess I'll keep reading until I think I'm comfortable enough to start the logging process.

Tonight I returned the Predator back to stock, then flashed the Predator-modified tune from HPTuners to the Av. I need to modify the tune to change the torque converter lockup, to completely eliminate the speed limiter, and to completely eliminate torque control. I've looked Main One's tables over and may start there to see how I like the changes.

[MyBigToy]

It looks like I've got some work to do.

I changed the torque converter lock points, shift points/rpms, and totally eliminated torque management. The torque converter is still not locking where I want it to and it's very quick to downshift with little throttle input.

I bumped the shift rpms & speeds up a little so it appears I may now have to pin my crank pulley. Between the higher shift rpms and the total elimination of torque management I believe I heard the pulley slipping just before shifting. And I haven't even switched to the 3.25" pulley yet! This is going to get interesting and maybe even fun.

[INresponse]

3 things:
Good luck.
Enjoy.
If you make a change and things don't seem right go back to the previous tune and look things over again.   

[Main One]

Sorry for the delay, but you've got mail!

[MyBigToy]

I've got it and have spent a few minutes scanning things. 

You've also got mail.

[ROBS6T8]

   Sorry guys.  I didn't want to sart a new thread... just thought I would throw it here.  I did a lot of research on here regarding the different programmers and decided to go with the Predator.  I thought the HPT would have been to much for my lil' brain to handle.  I just installed the predator and what a difference it made.  I just did the 87 octane tune and WOW!  I didn't need much more HP or torque with the 8.1.  I just needed a little work with the tranny from shifting so much with the large tires.  It worked.  Now I can play with other parameters... maybe?

If you want to start changing other parameters you should take a look at the Diablosport forum; I suspect you already have. There are some pretty easy to understand threads on changing the injector slope and timing. It's pretty difficult to get yourself in serious trouble only messing with shift times/mph. I believe MonteSS is the one that posted the threads I'm referring to; he's posted in this thread also.

I've got it and have spent a few minutes scanning things.

I saw a few things of note:

1.  The changes to where it is trying to balance the STFT dithering at higher o2 sensor levels even at fairly low airflow should give you a richer than stock AFR.  Don't know that is needed at low airflow levels, even with a blower.  FlaBouy has talked to me about going leaner in airflow levels representing cruising conditions to improve fuel economy.  I haven't tried that yet, but I may be experimenting with that soon.

2.  #1 is offset at higher throttle levels where Power Enrichment kicks in by not commanding as rich a condition in Power Enrichment compared to a stock tune.

3.  I noticed that your normal shift speeds are fairly close to where I have mine.  My cruise control shift speeds are the same as my normal, but your cruise control shift speeds are quite different from your normal.

4.  I noticed in your Force Current table that in the column for 100% commanded line pressure, you have it set for 0 current, which should provide maximum pressure.  I thought that I had read somewhere that it's a good idea to put the values in this column to max current, I believe 1254 mA.  The stock tune puts high values like this in this column, as did Hypertech when set to firm up shifts.

Saw numerous other things that were different from stock or the direction that I have gone, but these above were the ones that I found somewhat surprising.

I haven't messed with any of this yet so what you are seeing is based on the Magnacharger tune. I've got a lot to learn and I haven't attempted a log yet, much less working on a VE table. And from what I've read, that's the first thing I need to attempt before messing with anything else.

2.  #1 is offset at higher throttle levels where Power Enrichment kicks in by not commanding as rich a condition in Power Enrichment compared to a stock tune. Again, this is coming from the stock Magnacharger tune as I haven't messed with anything.

3.  I noticed that your normal shift speeds are fairly close to where I have mine.  My cruise control shift speeds are the same as my normal, but your cruise control shift speeds are quite different from your normal.I changed these for the normal shift speeds but just haven't copied it over to the cruise table yet. I don't get a chance to use cruise that much so I wasn't in a hurry to get it copied over.

4.  I noticed in your Force Current table that in the column for 100% commanded line pressure, you have it set for 0 current, which should provide maximum pressure.  I thought that I had read somewhere that it's a good idea to put the values in this column to max current, I believe 1254 mA.  The stock tune puts high values like this in this column, as did Hypertech when set to firm up shifts. This is something I guess I need to take a look at right away. Again, I have't changed anything here.

Saw numerous other things that were different from stock or the direction that I have gone, but these above were the ones that I found somewhat surprising.

Thanks for the feedback.

correct  

yeah, do some data logging and get your average LTFT's dialed in so that they're between 0 to -2.  You adjust your injector slope in order to do this.  Doing so will gain you even better throttle response, acceleration, stronger/harder pull, and better mileage...

here's the info on how to do it:  http://diablosport.com/index.php?name=PNphpBB2&file=viewtopic&t=917


and, you'll get even better power if you use 91/93 octane gas and the diablo performance tune 

[ROBS6T8]

Thanks BigToy and Monte.  I've seen Monte's posts over there a lot.     I actually have the Diablosport forum open in another window... I'm outta here.
