Rocket Man's 02 Denali Build Thread AKA "THE BEAST"

[Dantheman1540]

I’m thinking I’ll be buying HP Tuners and starting to do my own tuning. I just need to know if I can do some slight mods to my existing tunes instead of starting from stock since I’m not ready for that. That way I can look at data myself and command shifts. Frank @Performabuilt says he’d like me to disable the 3-2 shift solenoid since he says it’s not needed with their builds and can cause limp mode. I have wanted to start doing my own tuning, maybe it’s time. I’m out of patience with Justin and his 2 week wait for an answer. They’re ok for getting your tunes but for any technical help like this not so much.

Self-sufficiency is the way!

Last I looked into this, they don't interface and there is no third party interface/translator. You have to manually copy the tune in each table/box/option. Also, some tables are oriented differently. For example, (using random items) with EFIL, the MAF scale might be on the X axis and the IDC on the Y axis, but it's opposite with HPT. Supposedly, you can rotate and/or flip them to make them easier to compare and copy.

Is this a recent change one of them did? I have a file labeled "BBP tune" but it's in HPT config and I can open and mod it as I please with HPT. It was what I pulled off my Silverado when I switch from BBP to HPT. Of course, you can't take an EFI Configed tune and read it with HPT but if you load it to the ECU with EFI then copy it from the ECU with HPT then the MPVI should translate it to HPT config and you should be able to work it.

Now this experience I'm talking from is circa Jan 2017 so maybe stuff has changed but I don't see why it would have.

I don't need to interface it as in take the tune from an EFI Live file and work on it, but to download it from the vehicle and then work on it. So, like Dan was saying it should work. Frank @ Performabuilt just told me HPT will modify any tune as long as it's not password locked and if it is I'll get the password from Justin. He will no longer hold me hostage! I was shopping for the Mpvi2+and found it plus 2 credits for $344 from Hinson Motorsports on Amazon which is $55 off plus they send 2 t-shirts yay. I can always use a couple work-on-the truck shirts. Plus as far as the harness is concerned there's 2 options depending on the pressure switch in the trans and the only way to know which one you have is to look at it according to Frank. I'm not dropping the pan yet so Frank gave me an Amazon link to the whole kit that has a harness, pressure switch and all AC Delco solenoids for about $150 so I ordered that and another gallon of Dexron VI. This $525 better fix my problem or else.

Fingers crossed man....

IDK if the MPVI2+ has an option to plug the wideband signal straight to the device or not but that is why I bought the MPVI2 PRO, if not you will have to do some kinda sketchy wiring with the EGR port or AC pressure sensor, and it's a PITA IMO.

I don’t need to do that though do I? Can’t I do like BB does and just look at data logs and use that to tune? I don’t plan on doing anything with the engine tune anyway tbh. It runs great and I’m not planning on doing anything else to the motor. The Pro is another $300 as you know.

If you don't plan on touching fuel or spark then you don't need it. I guess they have been tuning your truck using the narrow bands which is kinda sketchy.

 

[pwtr02ss]

Id buy the pro if you're going to buy one. That way you don't look back and say "I should've"

I mean, I bought the pro and still don't know how to tune so maybe I'm doing it wrong...

Well crap now you got me thinking. Maybe I should cancel that order and buy the Pro. I mean I have the wideband cable routed to the console already…

I did that the first time and as soon as the V2 came out I grabbed a pro so I could data log with the AC on.

Not saying BBP doesn't do a great job but its very possible theres some power on the table or even some spots that could use cleaning up for max efficency

Knowing how smart you are and how methodical you are on all your stuff you will quickly be digging into things you shouldn't and want to know if your fueling is worth a damn or not.

Jesus now you sound like a salesman, calling me smart and methodical and sh*t lol. Fine, you guys are right and it’s not time to worry about a few hundred bucks. I put in a cancellation request on that one, as soon as it’s approved I’ll order the Pro. The same company has it for $595 including 2 credits so it’s $250 more.

That's what I'm talking about! We might need a thread dedicated to HPT.

Well...Someday I'm gonna stop dicing around so, great idea!

 

[Rocket Man]

Of course the tuner already shipped minutes after I tried to cancel it so I'm stuck with it. Kidding, I'll just return it when it gets here, it just means it ties that money up until i ship it back and wait for a refund. I went ahead and ordered the Pro.

 

[pwtr02ss]

Tool will be there Thursday supposedly. Lmk if you don't get it

 

[Rocket Man]

It’s going into limp mode pretty much immediately now and constantly throwing P0785 3-2 shift solenoid. It seems like it got worse right after I disconnected the harness and inspected the connector.

Hopefully the harness is your answer
