His sig says stock but shouldn't he still be able to boost higher with HPT and 2 (2.5?) bar sensors?

 

I think the stockers are good to 25psi. Isn't there a write up on ramping up the boost or adjust waste gate via hptuners?

 

I think the ECU will read them until about 21.5psi then lose control but a lot of people tune with the stock ones and it seems to work. He has an '08 so the anolog pillar gauge should read fine. I do believe that he should be able to get to 25 pretty easily but I have the 3 bar sensors so not sure. Just sent him some tunes to compare with including a BYT/Term one that's for E47 but is still very informative to study.

 

I adjusted the DAL and MALT without going crazy and used the DCC from a guy who was drag racing his Solstice thatt I've since modded. I'm sure there's a thread on HPT forum somewhere but the search engine there (and here, I think it's the generic template the hosts use) stink.

 

I'm on 2 bar. 21psi is pretty easy to get. If you try for anything higher, you need to do it with a good balance between MALT and DAL as well as starting to disable some of the nanny controls. I'd rather have a well balanced 20psi tune than one that spikes to 25 and trails off. Anyway, I don't want to get in between folks with more experience than me, just thought I'd share.

 

yes stock.. And i have yet to load a new tune comparing yours to mine, been busy. but we will see what happens

 

Just ordered my HPTuners Suite (sorry rally, you won't be able to give me h3ll for much longer ). Now, for you guys that write your own files, what tips do you have for me for getting started?

I have been reading the HPTuner LNF threads religiously, but real world tips from you guys/gals on this board are like gold.

 

My friend and i just used the Tuning guides they have and it was pretty straight forward. Didnt do the cam timing though.

 

While I'm not as experienced as some others here, here's some feedback based on my experience:

• Learn how to log on stock before you change anything. You can make big mistakes if you change things based on an improper configuration.
• Learn how to tune the MAF first. I didn't do this because I went in the order of the guide I used. It just caused me extra grief since changes didn't do what I expected them to. For example, I lost boost for one key cycle because of fuel trims being too far off.
• Make small changes and log the result. Don't go straight to the numbers in a guide. Just because you found it in a guide online doesn't make it the only way or the right way.
• Don't remove any nanny controls until you are comfortable with your tuning ability.
• Do your tunes as versions instead of overwriting the same file. That way, if you aren't happy with how your tune is shaping up, or if you make a mistake, you can revert to an earlier version.
• I preferred to be conservative at the top of the Desired Air Load table and use the Max Air Load Torque table to shape how the car responds up top and in the transition to higher power. I felt like it gave me better control on how the boost comes on and stays on without dinking with the wastegate tables.

 

Thanks Breadfan. Exactly the type of information I was looking for from you guys. I am really excited (and a bit apprehensive) about getting this started, so y'all might see some more questions from me.
