HP Tuners recently released their software for the LSJ engines, and this will be opening the floodgates for performance improvements in the cars with these powerplants.

After spending several hours on the dyno with one yesterday, we were amazed with how ‘touchy’ the tune is on these cars, and how much opportunity exists. But with literally hundreds of parameters to adjust, this is not a task to be taken lightly. And right now, there are many parameters in the code with incorrect or misleading nomenclature, and some of the scanning functions give inaccurate feedback. So it’s going to take a tremendous amount knowledge, ability, time and effort to get these tunes dialed in correctly.

In 2005, we dyno tuned 92 cars, and programmed many hundreds of mail order PCM’s. We plan to lead the way with LSJ tuning as well, and for this reason we’re now offering five free INTENSE LSJ PCM/Dyno Tuning Sessions. Ideally, we’d like to get one ‘guinea pig’ for each of the following vehicles:

2004 Ion Redline LSJ
2005 Ion Redline LSJ – Mike Vanderhorst
2006 Ion Redline LSJ
2005 Cobalt SS LSJ
2006 Cobalt SS LSJ

The ideal candidate will have the GM Stage 1, GM Stage 2 or INTENSE Stage 3 kit, have 42.5 pound/hour fuel injectors already installed and still be running the factory airbox. Exhaust and other mods are optional.

If you’re interested, please email me directly at ScottC@INTENSE-Racing.com with your name, the year, make and model of your car, your complete mod list, how close you are to Plain City, Ohio and when you’d be available for a few hours of tuning.

 

sounds good. so what did u come to a conclusion with when u were tuning yesterday? did u see any gain results?

 

Yesterday Scott got my car to an amazing linear on the A/F ratio. There was 3+ gain in peak horsepower (only with tuning the air/fuel and not running it up to the 7000rpm. With just the tuning of the ratios he got a 45hp gain in the mid range though!!! Extremely noticeable and very helpful!!!

 

Nice. If I was up there I would do it, but I don't think I can get the time off to go up.

 

I can do it for the 2006 cobalt ss. I have the intense kit. I can come any time during the week so let me know If you need me. How much does it cost and do you dyno tune it?

 

WAAAIIIITTTTTTT a second. u gained 45 HP off of this? DAMN!!!!!

 

The test cars will be no charge for dyno or tuning.

 

The ideal candidate will have the GM Stage 1, GM Stage 2 or INTENSE Stage 3 kit, have 42.5 pound/hour fuel injectors already installed and still be running the factory airbox. Exhaust and other mods are optional. Would you be able to reinstall your factory airbox before you come out?

Yes, as I posted above, we're going to do the first five cars for free.


Yes, an 'INTENSE LSJ PCM/Dyno Tuning Session' includes a dyno session.


This was in the mid-range, which makes a MAJOR impact on the 'area under the curve'.

 

Very impressive. I can't wait to see what you guys can wring out of this motor.

 

I've got a 2005 SS S/C. I'm in the Cleveland area. I'm not staged yet but have been looking into it, unless I bring it down and have you guys install the Intense Stage 3, then do the tests.

Also...

How long would you need the test vehicle? Why don't you want one with an aftermarket intake? I've got the fujita on there right now. But I still have my stock one that can go on it.

 

I have an 04 redline with stage 1 but a Typhoon intake and there is no option for swapping it back to stock.

 

sounds interesting

 

PICK ME!!!!!!! i'm like an hour away TOPS!!!

E-mail sent!

 

How many timing advance for the last RPM's ? Did you mess with the timing ?

 

The first car we tested only had 92 octane, so we weren't able to increase the WOT ignition timing beyond stock. We'll be experimenting more with this in the near future.

 

SCOTT!

I fired of an e-mail to you

stage 1 car....air box can be made stock

 

Email sent!!

 

Thanks everyone for the tremendous support!

I'll be in touch with everyone over the next few days, as I try to catch up with my completely overwhelmed inbox.

p.s. - please understand that we're only planning to do five no charge dyno tunes initially. As much as we'd love to do a hundred for free, that's just not in the cards...

 

you get plenty then huh.... just wondering on how long till you think somthing will be out for sale

 

damn guys, wish i was at home to give you my car, you can have it for the next month and a half if you want...I'm in kuwait don't need it right now...gotta come to ohio when i get home anyway...hint hint...plus i'm gonna be paying you to install control arm bushings and the stage 3 and get tuned and...god knows what else...cmon you know you wanna car to work on...hehe

 

Here is the Dyno Chart For Mike's Dyno Session. Notice the HUGE gain in the mid-area and the flatness of the A/F Curve...

 

That a/f is crazy!!! The hp is crazy as well. Dude......I want a tune...How much will you be selling them after the 5 cars go? $400?

 

did you alredy make all your pics for who your gonna tune?

 

We just completed our first twelve hours of LSJ dyno tuning sessions, and we've learned a LOT! Rob Archer of Hoosier Performance and I worked together on the tuning, and with our combined experience we were able to make some great things happen. I was pretty pumped when I got home at 2:04 a.m., and I don't think Rob would have gotten home until almost five o-clock this morning.

The HP Tuners software is working quite well, and we're working with them to make it even better.

We'll be posting several dyno charts up over the next few days. You guys are going to be impressed by how nice we've gotten the air/fuel 'curve', and amazed with how much more area can be added under the horsepower and torque curves.

p.s. - we'd like to give special thanks to Mike Vanderhorst, Chris Kinzer, John Harbert and Dan Testa for donating their cars and time to this project, and for driving all the hours they did. Howard and Brian Turner of Dyno Tune Motorsports are always great to work with, so props to them too!

 

What a night!! I got home at 4:45am Only left the road a few times
