STFT Banks 1 & 2 - What is normal ?

[alex@ABRhouston]

How is that fixed?

How is that fixed?

The original OP questioned how much of gap between the two banks is considered normal. With help I was able to reduce the gap between the two banks.

The other issue was maxed out trims, there is only soo much I can do with the scalar banks "based on what I know". I did mention there is a bit more touching up to do, but without having to raise my scalars to oblivion to reduce trims.

Also I noticed in couple of test logs, when the weather is cooler trims barely exceeded 20%. Its only when its hot out I would see trims almost maxing out in the begining.

More likely also I have more than E50 mix in my tank even though the math in galons are correct as the E85 has been tested to be actually E90+ at the Shell gass stations in my area

All this is taken into consideration of how far to take the scalars.

[alex@ABRhouston]

why not take a sample, and measure your E85 content?

It was a PITA .....

To everyone, it was a pleasure, and thank you for all the help and info. It served well and hopefully it will help others. The issue has been technically resolved. Might need a little bit more touch up but for now I am leaving it as since I will not be adding anymore power. I need to stay content or else Im gonna get myself in some serious trouble....lol..... http://datazap.me/u/buraq/beastmode-...-17&solo=11-12

Wow your LTFTs are solid. Mine are all over the place compared to yours.

Can you take some screen shots of your scalar tables and the spool table you mentioned and post them here for reference.

So...it sounds like you are over this...but my first reaction when I saw that log and read "The issue has been technically resolved" was

I try to stay out of the tuning side of things but I'm going to make a couple points because I don't want to see you over look them. I realize this can be a bit overwhelming, but in my opinion there are a couple things I would address if it were my car.

First....

I'd rather my AFRs were forced rich, than lean.... especially since you are doing drag strip runs.

Your trims are still pretty high...remember, these are Cobb logs...not JB4 logs...don't confuse the two.....

Second....

I've seen a couple of your logs now and they all had the same thing....multiple timing corrections.

In my opinion...you were concentrating on something rather trivial and overlooking other things that I'd consider more important.



So...with that said, I hope this helps a bit and doesn't just provide another source of frustration...if it does....I'd really recommend contacting PTF or somebody along those lines....JMO

I will post just the section of cells with the changes and explain what needs to be done with the entire table. I dont want to post the entire tables for mutual reasons. I have to be careful with it cause I have to take into account that E85 here is not always E85. Here is the latest log with some touch ups. I am making one more final adjustment. http://www.datazap.me/u/buraq/beastm...ata=2-13-14-15

Fist I appreciate all your help, and suggestions, it helped dramatically. Though there is nothing in my logs that I have "looked over" as I am very aware of the timing corrections and what is causing it.

This "was" my finally map http://www.datazap.me/u/buraq/overki...7-8-9-10-14-16 . Its the same as the current map I am working on with the exception the current map has now improved trims and significantly "increased WGDC Adder and WGDC Ceiling". To cure the current timing corrections as you pointed out it is to reduce the adder as it was previously. I am trying to find another way without having to reduce the adder. IDK what it is but I beleive it could be too much back preasure ? Not sure wont find out until when I remove the mid-cats.

Btw PTF have already tuned my car months ago, however, I just decided to do something on my own. This is what the PTF log looks like on my car http://datazap.me/u/buraq/ptf-e50-v4...2&zoom=110-327

I have settled to just run their tune "with meth" in the future. I am a picky customer and didnt want to annoy them so I just decided to do my own thing, plus I wanted my overboost feature back. Re-enabling the overboost feature requires much more work and calibration with various tables. Most tuners use a template as a starter which will be of no use when getting back into the IS overboost feature.

I know HFC downpipes are always a touchy subject, but with the boost and timing targets you are looking to hit on stock frames, I’d really consider pulling the HFCs. Keep the secondaries if you want, but the primaries are going to be creating a huge bottleneck to evacuating exhaust gasses. You are creating a ton of heat and pressure on the stock frames with that boost curve, I’d be looking to move it downstream as quickly as is possible. Wouldn’t surprise me if the “noise” you are seeing upstairs is related to that.

Just my 2C, you know what you are doing so please don’t take it the wrong way brotha!

Yup you hit it right on the nose, "noise" was the complaint about the timing corrections even with the PTF tune, not knock. I have my "theoritical" reasons why I am not going to go catless up front on these stock turbos.

If I have to back down off the adder even after removing the mid-cats then it will have to do till I get upgraded turbos

[Steve@Fuel-It!]

Sounds like you're all over it....

Your post-shift timing is flawless on this log.

How did you do that?......I am jealous

Its the DCT, all depends on the mood of the car, at times you will see no negative post shift timing drops also

http://datazap.me/u/buraq/beastmode-...0&data=2-13-17

For 335is owners with DCT and using the Cobb AP OTS maps, you have to revert back the Y-axis back to stock in order to see instant post shift timing recovery.
