    Re: Dyno Tuning tip list

    I have found out HPT Support is in the mode of denial on any issues. Bottom line is that HPT supports stock run of the mill, no frills cars like GMC trucks, Corvettes, mustangs etc. You get into the more technical forced induced cars and they lack the detailed stuff we needto complete the jub. SO in a nut shell They do support the STS-V by phisically connecting to the interface and talking to the computer. As for having all the functionality the V software has in it, they do not. I am not done with their support or sales. Their view is if HPT can modify the basic engine (No VVT) functions and the basic tranny functions that Stabilitrac, tq management, and TC should fall in line on their own. Which is where the are wrong.

    Re: Dyno Tuning tip list

    My question to them.
    "My big concern is these cars have 5 different driving options. (TC button)TC off, Comp mode, and TC and Stabilitrac off. Add in (grar shifter), automatic, sport stick mode and manual matic shift. each of these settings can be done in combination with each other as well. Each of these affect shift points andTC. And where do you begin???"

    Their answer
    "The modes do not effect the tune other than trans shiftpoints and trans shift TM."
    .
    .
    .

    The TUNE itself can change shift points If we program them. SOO how does the tune not affect the modes? They go hand in hand.

    Re: Dyno Tuning tip list

    well there isn't anything for the tc off, but for reg mode, sport mode, and tap mode, you can separately adjust the shift points and torque converter lock/unlock points. of course, the tune is the same for all trans modes, but that's the ecm, not hptuners.

    does that help at all?

    Re: Dyno Tuning tip list

    Ask yourself "what is my goal here?" TC and stabilitrac have no competition application, so if the idea is to generate big numbers, turn them off and concentrate on programing in that mode. If the idea is to fine tune it for better street and casual track day numbers (when having those electronic aids in the background can be helpful), then pick the combination most likely to suit your skill level and driving style.

    Re: Dyno Tuning tip list

    I started out going for big numbers and tried to turn off TC and Stabilitrac but that left the car in limp home mode when we tried to test on the street. So in short I will initially go for good numbers then tweek for street/track driveability. Hopefully finding a balance at the end of the day.

    So what can I expect to get out of HPT software at the end of the day? Just a decent engine tune and some trans adjustments?

    Re: Dyno Tuning tip list

    yes, a good standard tune through the timing tables and other spark adj that we spoke of, as well as eliminating trans torque man, which in itself is worth the $, and if you want to, some wot fuel tuning...the same as any other tuning box or software out there...no magic. of course there are a million other things to touch if you wanted to, or changed components, but prob not necessary. as far as your wideband bung...the only thing you are tuning is wot, not really everyday driving situations.

    Re: Dyno Tuning tip list

    Scheduling another session next week. With some of the tips I and the tuner picked up since the last tune we sould be able to get her dialed in this time. I have decided to leave TQ management alone until we get the engine tune just right. Then if there is time we will tackle the trans and TQ.

    Re: Dyno Tuning tip list

    My tuner is a reseller of EFILive. BUT we are going to use HPT first then we will take a look with the EFI to see if there is any difference or extra bits that may get us more. It should only cost $100 to use the EFI. The reason I am still going with HPT as my primary tool is because I get to keep all the tuned files on MY laptop for further use.
