I didn't even think about it until I saw a post on LS1tech about an SS Cobalt HP Tuner. I have HP Tuner for the 1998 LS1 Z28 and for a 2001 V6 Firebird. I could add the HHR to it and have it tuned. The only thing, who would do the tune? Should I just contact a professional and see if they could build the Parameters I would want or have the guy that tuned the Z28 do it. Would it be the same concept?

First you need to download the latest HP software from your account on their site. Then visit their forum for some very good info on how to do a decent tune yourself. Before tunning, download your current stock tune and save a copy in case you have to reload it.

You could also visit Adm Performance and buy their stage 1 or stage 2 tune files and use your HP Tuner suite to load it to your car.

$199 for a tune isn't bad at all. The Stage 2 wont work with mine because we only have 91 oct in AZ. :(

That is if you send your ecm to us.

Send your stock read and I will get you going in the right direction for $100

Just wondering what you change and if the stage 2 will work on 91 oct. Yes AZ suck with fuel

Andy

I've sent you a few emails concerning the stage 2 tune you offer but I haven't heard back yet. Can I purchase it without sending the ecm to you or is the tune I already got all you offer for HP Tuner people?

(BTW - I like to talk to you about the base tune you sent when you have a few minutes. I've noticed something that might be of interest to you)

Call or pm me here.

Stage 2 will not work with 91 octane.

Stage 2 was developed after some extensive testing on the dyno and street.We are already working on a stage 3

:cool: Just installed the HPT with ADM's stage 2 tune last night. Makes my butt dyno all tingly. Serious tire torture for sure. This tune rocks. :thumb: Thanks again Andy. :one:

Yeah I knew you would,you can't describe in words enough what 50ft torque more is at 3k.



Andy

I wish you guys weren't so far away. I also wish the Stage 2 would work with 91 otc that we have out here.

Not far at all-Just an email away!

If you have Hp tuners,we can do business.

Sorry if this is a little off topic but I am going to be moving to Phoenix in the next few months. Are you serious?!?!?! You can't get anything higher than 91 octane in the entire state?

That's a big 10-4. Also true in CO and CA, as well as others.

:D Agreed :D , It's like a whole different car. Just awesome :bow:

Sorry if this is a little off topic but I am going to be moving to Phoenix in the next few months. Are you serious?!?!?! You can't get anything higher than 91 octane in the entire state? Correct. But, I don't see why the tune wouldn't work. Im running 11.5.1 compression on the LS1 and no pinging even with tuned for Nitrous. I think you might lose a tad HP but nothing that would cause it to ping. It's probably never been tested to find out.

You coming from Lackland AFB? Are you going to Luke AFB? I live close to Luke.

Also, do you have an SS? Cool to have a meet up at a car show.

Is your LS1 running 22+psi at 11.5-1???? That might make a difference:smile:

You can't compare knock characteristics between PFI and GDI engines. The design of the GDI engine provides for a much higher level of knock resistance in all engine modes. Under high driver desired torque conditions, homogenous knock mode is used during the transition between stratified lean and homogenous modes to keep knock events in check. No matter what, you can't exceed the knock characteristics of the fuel.

Then HP Tuners is going to have to create more parameters or anyone in the West will have no reason to mod there HHR's because codes will pop up.

Well what other ave's can we do?

It's not an HPT issue, but rather an engine design issue. The GDI engine operates much differently than a PFI engine. These design characteristics create the high levels of efficiency realized by this engine.

You can mod and tune as you please, but you must stay inside the operational parameters of physics, engine design, and fuel properties.

Im gunna have to go to plan B. 406LSX Block :lol:

I guess the best Idea is to have 2 tunes. One for race fuel and the other for 91oct. I know where to get 100oct but only for racing. I could do all the mods and keep a basic tune for the fuel we use here, then when Im in the mood to race, I can upload the race tune and use the higher oct fuel. Might be a pain sometimes but I could run better track times.

Get a fuel cell so you can carry both with you. :D

People do that but I would still have to change the program. 91oct and 3-4 gals of 100oct will bring it to the octane levels that is required. no big deal. :thumb:

...you must stay inside the operational parameters of physics, engine design, and fuel properties.

Stop all that crazy talk this instant! :D

Fuel properties? What if I add one of those five dollar bottles of octane booster? :lol:

Three cars ago with my Ranger, changing programs could be done with a toggle switch. One for good gas mileage on 87, one for a Friday night with a tank of 93. Sounds too simple, but the tune was worth 20whp on that V6. I wish there was a way to do that with the SS. Boost controller maybe? Someone smarter than me want to chime in on that?

I guess that depends upon where they store the flash program/data on the controller. If it is internal to the microcontroller chip then it won't be easy. On the other hand if it is all external on a separate flash chip then perhaps it could by done by using a toggle switch to select which flash chip is the active one.

It would entail pulling one of the computers apart and seeing what components are used and how it is all wired up.

Any one have pictures of the controller with the covers off?

IT COULD BE DONE VERY EASILY.EXTERNAL...........:nuts:

Well don't tease us. Spill the beans.

Get the message about the SSQV? Since you didn't get my message about my address, I wanna make sure you're getting them. How's the intercooler coming?
