Hi Darek,
Nothing for pre-2019 GTs? Asking BC the 16-18s are coming off factory warrantys now and owners more motivated to tune non warranty cars. Also, any factory tunes available in a library so...
Is there a factory tune in a HPT library I could start looking at?
Thanks,
Thanks for the reply! Appreciate it. This gives me a starting path to walk. I did see the C63 supported and was hopeful.
Best,
I've recently acquired a 2017 AMG GT (C190). I'd like to begin tuning. I am an HPT user and got pretty good tuning LS(3) engines including FI builds.
For anyone understanding the HPT platform, and...
Yes, I should have mentioned MAP as I manipulated that too.
Pretty normal from my experience. I've done a lot of DLs and I have that table set very low to gain PE at the place/RPM I wanted based on where my boost was coming in.
From 4000 to 8000 I am set...
The ECM works from the HO table to the LO table based on knock retard events and the knock learn factor. This can be set/changed. Whoever tuned your setup might have modified that.
If the HO and...
If drifting is what you're trying to do, your torque management settings are preventing wheel spin. You have both spark and ETC controlling wheel spin.
torque management > general > Traction...
OK makes sense now. That table becomes a final timing in a torque event. Coincidentally, 14.5* is what I see too when the torque timing table obviously kicks in, then I can get saw-toothed timing...
Thinking about it some more, is spark min - tqmgt a spark adder or a final spark? The +14.5* then makes sense if it is a complete override and a final spark under a torque management event? Thanks
Interesting. I looked at Spark>advance>Spark limiters. etc. Question: Why did you bump the #s to a plus 14.5*? and not 0.0*? Aren't you now adding timing in a torque event?
Thanks!
Thanks - just took notes of that and will look at it.
I am further refining my tune - 09 Corvette, 6 spd manual, all stock except an A&A Si-trim kit putting out a max of 6 psi.
Most of my tune is completed and I am satisfied, I am now looking into...
I very much appreciate this GHuggins and want to say thanks.
I am considering long tubes on my 09 Corvette with an A&A Si trim. As a tuner student, I've anticipated there will be a timing issue...
Thanks for info 07GTS. Much appreciated. You've given me other things to consider, and this is going into my "database". Your comment about "boost up in an instant" is so true. I am still trying to...
Followed Ghuggins advice - did a number of iterations of tweaks and 10 or 12 more DLs Friday and today. I have very stable LTFTs now and consistently entering PE with -0.8% to -1.6% trims. I've been...
Thanks - I actually think I can do that!
Well, this is all coming together for me now. I think I've spent more hours over the last ten days and have read more about tuning with HP tuners than I did getting my Engineering Degree. and, my...
I wanted to open another topic, any opinions. Even though I am staying out of the PE/boosted range and focusing on getting the low RPM end tightened up now, I picked up some info on older threads...
So, good news. Just loaded the tune with the +12% Maf Freq adjustment across the table and LTFTs are now 0 to -2% throughout idle and cruise up to about 2500/3000. Now, if it stays there I can relax...
Yeah, thanks, I have been a little vague, but this is a story a few weeks old. I have 80lb injectors and the injector data is correct. This is a small A&A kit SI-Trim on a stock LS3, and I am using a...
No just the stock IAT in the MAF, and should be the same MAF as the FI tune used. I just tried it, and not working very well. Have both tunes open in separate editor launches. Clicking on the...
OK Thanks! I never did get the IAT sensor table copied from the FI tune. Tables didn't match and since this was before startup, you advised just leaving the stock IAT. Now I'd like it over since it...
OK, so I'm taking in this advice, thanks! Put timing back to to the target FI tune. Now I'm going to experiment with the MAF freq table in airflow. I took advice above and another post from Carson...
