I say just go with Trifecta, or hit up 'ol man river Joe Rutledge (BennyHHR) and have him HP Tuners tune you.

 

interesting....my car is mostly stock, ive got an aero turbine exhaust on it and short air intake, thats about it...if i were to tune this car would it even make a difference?

 

It makes a difference, but obviously not to the extent of tuning a factory turbo car. More important than just the peak HP gains, we saw average HP gains of over 6whp and torque gains of over 7ft lbs at the wheels. It might not sound like a lot, but for a car that's in the 140s WHP range, it's pretty noticeable.

The Psykosteve 30 ft lb torque gain was on a RWD LE5, and the stock torque numbers were way lower than they should have been for some reason. Plus they were not peak numbers, they were the numbers at 3000 RPM.

 

you forget I am an 08 different ECU

 

Oh yeeeahhhh......dur dur dur........my bad, lol.

Oh by the way.....go check the North East Regional section. I posted up the flyer for the 2009 College Park Tuning show

 

awesome its that time of year again!?!?!

 

HP Tuners FTW! Been there done that..tuned 2.4 for a long time now..car is back to stock now except intake and catback..keep it my DD, should be getting z 04 z06 or decent priced c6 vette

 

Why don't you 08's try to call around and get some support?

If you vote with your $$ that you're looking for a tuning solution, it will appear. How different can the cars be?

 

Rumour has it, that HP Tuners may support the E37 ECM late summer. I have no idea how accurate that statement is.

08 (E37 ECM) tuners are currently, LS2 Edit, Trifecta, Vector, & Westers(I think)

 

I am going to have to talk to those LS2 Edit guys and see if that will work, truly, on the 08s cause if it does then that is my path.

 

The only trick with LS2 Edit is that ECM is locked "to" the programmer. If you buy LS2 Edit, and have a tuner use your program on your laptop, then your O'K. If you go to a tuner who uses LS2 Edit, on their laptoip, then you always have to go back to that tuner to revise your tune. You cannot adjust it yourself. If you want to return to the stock tune, you still have to return to the original tuner. Also with HP Tuners, you can use anybody's tune on your engine.

There is a statement on the LS2 Edit website that may help to explain this. copied and pasted:

A word of warning: Please only program your E/TCM using an LS2 file that was read from your specific E/TCM. Do not try to program your E/TCM with an LS2 file from a different E/TCM. To minimize programming time, we do not completely reprogram the E/TCM, only the data segments. If you use a different LS2 file, the data in the LS2 file may not match the code already stored in the E/TCM. If you attempt this, you may end up with a E/TCM that is non-operational.

 

yeah I bought a laptop just for tuning so that isn't an issue and I would keep a baseline file untouched so I could always go back.

 

The trick with something like HP tuners, is that you can share files, and obviously, compare results. With LS2 Edit, you cannot share files.

One other item I have no idea about, is what are the differences in the tables between HP Tuners and LS2 Edit. Is one more detailled, or more customizable than the other? Is this even important? (This could open up a whole other can or worms. LoL.)

 

I wouldn't really want to share tables anyways, now comparing is just a screen shot away. But the customizing is something to look deeper into.

 

Well, I am really intrigued. The big problem from my standpoint, is that in southern Ontario, Canada, (my turf,) there are only a few tuners who use LS2 Edit, and they specialize in V-8 gas, diesel and turbo diesel Trucks. Where as there are a number tuners proficient with HP Tuners, since the SC and early 2.4's have been supported for years.

So do I go for LS2 Edit, and the long learning curve, or wait for HP Tuners, and lots of local help?

 

but everyone is on a learning curve with tuning and every car is different. And I don't want to wait to the possibility of HPTuners thinking about making one for my car.

 

HP Tuners will w/o a be doubt making a tuning program for the '08 model LE5's.........its just a matter of when. But yeah, I suppose I don't blame ya for wanting to wait.

 

Yeah I am emailing back and forth with the guy right now. And from what I have seen in the user manual and screen shots it looks pretty straight forward.

 

Word, good deal.

 

I still need to get a wideband installed before I start tuning anything.

 

I suppose. I don't have a wideband and Joe has no problems tuning mine.

 

I am looking at getting the DashHawk to go along with this software so I can keep and eye on everything while I test drive the tunes.



P.S. to the OP

sorry for the half way thread jack

 

Gotcha. Yeah, I suppose that was the beauty of having someone else tune mine. All I had to do was drive. He did the rest. He data logged some normal driving, data logged some aggressive driving.........took a break.....reviwed the data on his laptop....made some adjustments........rinse and repeat until the sun went down and the car was running smoothly.

 

lol yeah I am going to be an info ***** on tuning, and I really don't want to leave it up to someone else.

 

I diddddd b/c I know zilch about tuning. But Joe took good care of me. He even gave me a folder with all the paperwork telling me all the changes he made and put his name behind everything. Also gave me a CD with my stock tune file on it.
