Alright, so after removing all the SAFC tuning, and several good pulls at WOT and many cold starts, I have come to the following: KCONST - 209 Latency - 600 I discovered that I needed to increase the K constant if it was going too lean at WOT (or decrease K it if went rich), from there just adjusted...

So I've continued to fiddle with the K and Latency time values and have gotten to KCONST: 182 TS14V: 720 Now when I get into boost under load it stays in the 14.7 range and doesn't go lean or rich. Is there a specific direction to go in either of the two values above instead of adjusting the fuel lo...

Adjusting the After Start Enrich, Cold Enrich did not seem to do what I wanted, so I just spent the last two hours trying to retune my idle with the SAFC set to zero. Starting with KCONST: 288 TS14V: 750 Experimenting with SAFC at zero KCONST: 206 TS14V: 680 I experimented with a few other combos 72...

I know they are for sure JECS, not Nismo, and think they may be modified (included a pic below). I had taken them to my injector guy to install them in the rail and pressure test the whole thing, he also confirmed the data on the birthsheet to be true. IIRC they were sold to me as Hybrids. Seank rem...

First post here, so bear with me - for the last four years I been running a JDM VG30DETT, dual Z32 MAF's going through an SAFC II controller to the stock ECU. I dyno tuned the SAFC for top end and had some adjustments at idle. I went on a trip for a few weeks and saw it as the perfect time to send m...
