Stuttering at WOT 5100-5600 rpms.

I cannot figure out what is going on, ive checked fuel pressure, timing on the plug and disabled all traction control. Also if anyone has any tuning suggestions let me know and thanks in advance. weird event.hpl9.22trying stuff.hpt8.26.cfg

why is your commanded AFR 25? (larger injectors?)

whats all done to the car?

Tune is whacked yo. Lol. AFR is 25ish yes, and your VE table is waaaaaay different from a stock E40 tune, as well as your MAF tables being ridiculously high. Like 1lb/min in the 1000hz cell. Also idle airflow is huge. Timing tables are 7* higher in both tables in some places. TB scalar is gigantic. I see in PE your desired AFR is ~13, which tells me you hopefully aren't boosted.

^tune has the maf failed...

Yes inj are 65 lbs so I half ed them and did everything necessary for it to run on that, the commanded afr is that way Bc of the 65 lbs, and it's a speed density tune of coarse it isn't going to look like a stock e 40 ve table. It's a ls7 with a 248 256 cam and 285 cc heads, nick Williams TB. Only reason it still has the MAF is because of the IAT.

My apologies, I was under the influence of some strong sleep aid when I looked at this tune lol. I noticed in the log your AFR in the specified RPM was 13.7 whereas it was 12.3-12.5 prior to that RPM.

that wideband read ~1point higher than what was on the gauge, so really WOT was 11.3-11.5 then went up to 12.7. But I just got a new wideband gauge (other was my friends) and I found it was way richer than that even I seen 10.8 at times so I feel that this is my problem.

Thanks Though You Guys

so after further review this did not fix my problem
