Cobb is taking so long, if the 1 month part is really true, I'm flying out to LONG ISLAND for you to tune it

Good looking logs. Hoping this means we are closer to Stage 2 and ATP/ATR then I originally thought after reading this.

NO need, with ATR members can help each other and get it right without the need for anyone to fly and fix something.

lol ok, but i am simply saying once ATR is out and explained, the purpose will be for the end user to know what to change. You just need basic understanding of what does what. But yea, I will try to help anyone who needs it. I am sure many guys on here are willing to help.

I'm looking forward to ATR giving us more insight into the DME. the boost on this log looks slightly higher than other FBO logs i've seen. With upgraded turbos should be lower if it's hitting the same "actual" load. What are the IATs?

well, ok, i give up, its my car and i can't believe how good these logs are...i was so excited and the first guy i sent the logs was none other but clap, my pcv enemy #1

with all the commotion on the forums about cobb/atr/atp and mainly just seeing the sick ass AFRs and timing logs over the past few weeks I've been intrigued how/if the car would run at all on this tune...everyone said don't try it, its meant for a stock car but I just had to give it a shot...

loaded up v2.0.1 initially, had throttle closure, loaded 2.0.2 standard calibration still throttle closure...just loaded the "V2" version of the 2.0.2 93 octane map as the car's a 6MT and I couldn't believe my eyes lol

There are many reasons why this is a shocker, main one being that this is meant to be a stg 1 tune meant for a stock car with no other mods...mine is fully bolted with RB turbos that flow quite a bit more than the stockers at the same PSI...shows what the ECU can do to adapt to free flowing mods...it literally took 2 pulls for the car to adjust and on the second pull things started looking great!

i still have my V5 procede for high boost fun but knowing/seeing these logs now, damn!!!

no meth on any of these runs but they're on Canadian Sunoco 94 pump gas (good stuff)

i have runs on meth as well and haven't noticed much of a difference but I'd bet it helps with heat soak as usual and improves run-to-run consistency but it naturally won't just add power as load targets are "SET"!

dzenno,

Are you seeing any AFR disbalance between the two wide-bands? Cause if you don't with COBB and you do with Proceed, then "Bwahahahah - Piggybacks!"

Getting the 2nd wideband put in right this moment procede still doesn't have end user custom tuning software so I don't have any control over any parameters other than peak boost on an already pre-set boost curve...after 3 years of constant tinkering with the N54 I think I'd have enough knowledge to get my own map going the way I want provided I had a tool for it...

which will come out first, ATR or procede end user tuning software? both have been promised for a while now...

Question shouldnt be who will be first to release end user tuning, but who will have the right hardware to control a car properly.

Glad it worked out for you Dzenno, have you matched up your wideband to the reading cobb spits out? Accurate?

Most importantly how does the car feel when you rowing through the gears?

Overall looks fine, but hard to relate to...

Any chance you could should show the Load graph?

So you're running $1500+ worth of tunes right now then? :

Are you gonna stay with the COBB or make up your mind later?

I have no interest in dynoing with Cobb on stage 1 maps...i'll do it when higher boost maps are released or when I get my hands on ATR..

my point in getting Cobb was to satisfy hungry curiosity and see if the car would run like shit with the stg 1 map with all my mods on it including turbos...everyone except almighty clap lol said the car would probably not like it with all the mods and I thought so too but it turned out to be a real shocker for a few people me especially!

Main things I've come to learn are:

1) My car has no "hardware" issue(s) meeting AFR targets quickly at part throttle or post shift

2) When adjusting AFR through a flash vs. wideband biasing like its done on a piggyback, AFRs can be hit almost instantaneously..With piggys its a bit of a game always...sometimes they hit the exact AFRs I think they will (based on previous logs) then all of a sudden on a different occasion they look a bit different everywhere...so AFR consistency is what I'm really talking about here...

3) Piggys have an upper hand in boost control...

4) After a whole bunch of tuning out misfires at high RPMs I'm just tired of CPS offsetting and I really don't want to use it. I'd like to be able to use it in only for meth safety integration and maybe use a standalone box for that but that's it. Not for timing control of any kind...

Disclaimer: These are all just my own personal opinions/thoughts/experiences based on tons of datalogs/runs over the last while and I'm not looking to debate/argue them on this or any other forum so please keep me out of it
