Data Logs! Post them here.

You already paid him,how much.. More than 350 usd i guess? say him you pretend him to. Reduce PI because you don t want an opening timePI of 16ms, and to scale the maf bettwr because you see a correction of 10% and that obvious he didnt spend time to scale it
That to start with.. And then see how the logs are

[steve99]

Arrh missed the cl loop correction % yoah looks like rr10 closed loop

If



its deliceous they are probably using hybrid speed density and they manipulate a lot of pi\di its very difficult to diagnose thier logs unless you have accesx to tune tables and settings


Somthing weird going on with fuel system though

[tomm.brz]

Well with those values they could just tune. Normally with maf and reduce PI.. Logs look so stupud and they think every thing is normal......

I don’t think they use maf calibrations as much as map. Sorry, my tuning knowledge is very limited, but that is what I have heard.

[tomm.brz]

If those are the results with their hybrid SD tuning... Oh god.

It looks like they could easily go away with normal maf tuning, they could get better results. And still the fact they underuse DI and overuse PI to the point that overpass 15ms of PI opening... Lets me think about their "work"
Good luck with them

Its possible he has some sort of fuel restriction ie partislly blocked filter or low fuel pressure from in tak pump, this low pressure is not monitored by ecu it only jas info about hogh pressurs fuel pump.


However i had a guy few monts ago with blocked fuel filter and it caused some very weird fuel issues as the ecu attempted to compensate for low fuel pressure

At first I was asked if I had upgraded the fuel pump because he was concerned that I didn’t seal the pump well. I looked that up and it was a common problem with the O rings, but I hadn’t changed the pump, nor do I know what in the data gave him that impression.

[Irace86.2.0]

FWIW, via email I talked to Zach, and it is clear they have gone far to consider the potential negatives of overusing the DIs. I decided to get 700cc injectors n a fuel pump upgrade, and I will be inspecting my DIs for any signs of damage to the seals.

I’m curious about the Edelbrock kit and how they manage to use a 3.25” pulley (82.5mm) without issues, but then again, hasn’t there been issues with their CARB tune and doesn’t DT sell a dbox fix or something? Either way, while the car and tune feel good 80-90% of the time, there feels like there is an issue and the data shows there is an issue, even on the 95mm pulley, so hopefully I can figure it out when I upgrade each componet.

[Irace86.2.0]

Update: on the 700cc injectors and im running the 11-12psi pulley without issues. There is probably still DI seal issues but overall everything feels great. Just tip in below 3k the AFR is lean. Going to do a check on those eventually.

Running Chevron 92 Octane from WA state.

OFT v4.02 Stage 2+

No idea what I'm looking at...any insight would be appreciated.

Thanks!

If you are asking why there is a boost reading it is probably reading boost/vacuum, and at WOT you should be at 0 and off throttle you dropped to 12 psi of vacuum.

https://datazap.me/u/transport3r/way...og=1&data=1-12

Running @Wayno Wayne roms 93 octane map at default maf scales.
Stock intake, drop-in filter, JDL UEL header/over/frontpipe.

logged with OFT so AFR numbers read 0.2 high.
Despite that I'm not sure if this is technically borderline too lean, it hits 12 (so 11.8 really) at some points. Depending on where I read about it it's either a problem or not.
In 4th gear (2nd link), there seems to be some knock, showing FLKC activity, but IAM never drops below 1 so I guess it's minor?

The car feels good, especially up top in 2nd and 3rd. When overlaying my old OTS 4.03 logs from last week in virtual dyno it makes more power past 6000RPM than before, but did lose a bit of mid-range, both of which corroborate my initial butt-dyno impressions. Running significantly leaner than on V4.03 as well (11.9 now vs 11.6).

Any suggestions? Thanks for looking!

[tomm.brz]

from my experience with 3 OFT, it s just the command afr that it s offset in the logs, so if the real afr hits 12... it's 12.
you should use the vgi maf scaling tool of kodename to scale the maf a bit better, there is a huge rich spot around 3500-4000 rpm and it would make your afr a bit richer after that, probably correcting a bit the flkc you are getting
but probably to eliminate a -1.5 flkc you also need to reduce a bit of ign timing after 6400 rpm

Thanks so much!

Wayne's website claims it's both AFR numbers that get skewed, but I can log with my obd reader to compare and make sure.

I did notice the rich spot as well. I'll give the MAF scale tool a shot!
