Thanks Ænema,
I just confirmed what you said from the data from my last run. I should've thought about my question a little more before asking; of course load is mostly due to boost! Interestingly, to your comment re: actual load calculation, it looks like MAP must be the most heavily weighted factor, just based on eyeball inspection of this graph. MAP and load are almost identical, and they follow the curve of boost. As for my TPS closure, I'm assuming I need to get into ATR and add a little wastegate early on in the RPM range? Re: my Cyl 4 -4 correction, I'm not going to do anything, since it's based on a single WOT run--I think I need to see if this is consistent. Thanks. |

Doing this you may run into boost oscillations(surges.) If you do that means you're close enough for the PID tables to try and correct it on their own(but can't) so just keep at it and you'll get there.

Just a grab a 3rd gear log from ~2500rpms to ~6500rpms and post that up.

I've known "rader1" for a little while through the other forum and we're working together on an update using ATR to help fix some of the more common issues(boost overshoots, adjusting timing/boost curves.) I know he's waiting on the vargas stage 2 turbos before we go to deep into it because he wants to focus on the WGDC tables and hybrid turbos are probably going to take quite a bit of adjustment so it should make a pretty in depth DIY.

Put in 5 gallons of E85 along with 9.5 gallons of 93 (had about a gallon or so left in the tank also) and flashed the OTS E30 map. Wow. Pretty nice. It was maintaining the 12 degrees of timing up past 5000rpm and going to 13.5 degrees by 6000. Didn't have room to datalog but I did have some good half gear pulls and such on the way home, and it is pulling noticeably stronger than on the Stg2+FMIC map, which was only carrying 4-6 degrees of timing through to 6000rpm.
Very nice! |

4-6 deg. timing seems a little low for S2+, I think you would have seen ~9*. I know on S1+ I see 8.25 deg. through 6k.

I have noticed some new findings after 1 week of installing the Cobb AP.
First, I used to have a ton of soot on the back of my AW bumper even after a good washing on the 1st or 2nd day. After 3 days, I noticed there is atleast 50% less soot on the back bumper. It is much better than before. The car must be running less rich at idle and low band which would explain why the pickup is much better. Secondly, I feel like the engine noise has slightly changed. Does anyone know if the Cobb AP increases the water pump pressure or low/high fuel pump pressures for Stage 1 -Drive? |

Here's the stage 1 sport timing table: You can pick out where you are on the table and your advance makes sense given that. You had 7-8 degrees of advance @ ~12psi boost. I had 12.75 degrees of advance @ 17psi boost. The timing and boost added together somehow makes up that "actual load" number. If you figure out what your actual load is, you can figure out where you should be on that ignition advance table. |

here is part of my log with my Pro E Tune E50, default log list. Pretty Sweet Huh... S1+ E50. No DPs so boost tapers down, mid range at 19 psi @ ~11.XX timing. Hits 12.75 at 18 psi, timing is held.

Yeppp -- Plenty of people running the MT, AT & DCT trans. With the tune, intake & downpipes you'll be running the Stage 2 OTS Maps. If you can budget it, I'd actually recommend you get an FMIC before the DPs to ensure consistent power numbers & not falling subject to heatsoak/reduced performance.

As far as bolt-ons are consideresd you're fine. However, the Procede meth kit requires the Procede as a controller. You're better off using the HFS-3, hardware wise it's the same thing as the Procede but has it's own controller.

Like Ænema said, you're better off with the Aquamist HFS systems (something that independently manages meth) & a trunk mounted meth tank (too many 135/335s have gone up in flames because of leaky windshield washer necks -- a trunk tank can avoid that problem). |
