currently for the VB chassis, COBB is the only way to go. The car HAS to be emissions in tact meaning NO deletes like j pipe, egr, tgvs. I can get you an Accessport shipped direct to your door as Im...

Ok, great! I'll check this stuff out! Thanks for all of everyone's help!!

Ben

currently for the VA chassis with a FA20, you are limited to tuning using a tactrix cable and subaruedit. Ill warn you though, subaruedit is kind of a pita. It does the job, and has all the tables...

Ok, awesome. What would you rec. on the fuel tuning? Make maf only changes or maf changes, then disable maf and make vve changes, or is there a more preferred way to do it?

Thanks!
Ben

Thank you guys so much for all the help on this! This is the info I needed to know. One last question I have is do you all rec turning off ltft permanently or just for tuning the cruise range, then...

ok, that makes sense to me for sure. I agree that you def need more fine control in the part throttle/low load ranges. Good info!

Thanks again!
Ben

I wasnt thinking I was hitting the ecu airflow limits, but I was concerned about reaching the top end of the axis shown in the tables. I just didn't know if I should make changes to the airmass rows...

ok, so could it be that the maf scale where Im making changes to it are just changing the reported airmass that much? Yes, stock injectors for now. The car was completely stock, I added an air-aid...

Thank you! This is a great asset to look over! my main question I guess is, why is it necessary to rescale with just the small part changes i've made? Since I haven't changed injectors, pulley, fuel...

I suppose it was the way I was taught, that said, I'm new to GM ECU tuning all together and trying to get the best understanding I can. For example in COBB AP maps or opensource on a Subaru, the maps...

I didn't seem to find what I was looking for in the search, I may not have worded it correctly though so please forgive me. I have a 2015 V2 cts-v coupe automatic and I have installed a airaid...

Nice. Thanks for looking into it, im hopeful for the platform, just trying to be patient!

I second this! Maybe Evan can help here

If you have a tactrix cable tou can also log through romraider while using hpt for calibration if you don't like hpt vcn scanner.

I will come in third here on an update Evan! Id love to see the things I originally mentioned available in hpt.

Yea having them is def a plus!

I may be wrong, but I believe the pro feature set will only allow 5v inputs for logging, not as an actual ecu input for corrections and such like tgv or rear o2. Maybe Evan can assist in answering...

I second this!!!

I second this! I could add a bunch of stock files!

So how exactly does this apply in the map? I mean, I read the description but my question is why have it as most Subarus dont even use the rear o2 once tuned. Most everyone with a wrx or sti use the...

Evan,
I will try, my best to get the requested info for you! I really want to work with you (hptuners) to get the subaru mapping improved and stable across the board. I see alot of these for tuning...

So, if you enable the input fpr tgv left (or rear o2) and set the flex inj scalar to your scalar thatyou need, will it run? Also, you will need to set the ethanol content sensor scaling to 0 across...

Oh no, I understand what you were telling me, but the only way I can get the car to start no matter what I do is tell it to enable flexfuel via tgv left. That is the only thing I have to do to the...

Got it running! Let me explain this for the others in this post!

SO everyone read the following quote from Evan.s@hptuners

"It's definitely not trying to use the SD tables, it's still in MAF...
