Fuel table question (high load low kpa)
4 Attachment(s)
Hi,
I just used travisb's fuel table smoothing calculator. Its great. I noticed that when I run auto tune it keeps adding fuel in in the lowest kpa cells when the engine revs are falling (like slowing down slowly) or when changing gear. I presume I am missing something in my settings as the car drives great, hits its my target AFR's all the time. I just dont know why the engine wants big fuel table no.s when there is no load. Table attached. I have lowered these no.s manually but autotune will look for no.s around 100. Any suggestions? |
i cant imagine it drives great with that fuel table. just imagine how great it will feel when you actually fix your issue of that horrid table...

Those cells are hard to tune without a dyno. Put the car in 2nd and roll around at 50mph and tune them manually. VEAL has a hard time understanding what to do when transitioning to over-run.

things i noticed:
you have 265cc injectors but a req_fuel for 600-800cc injectors. youre using include AFRtarget your ignition table is very retarded |

I had the spark table tuned by a tuner on a dyno. He said it was knocking and I asked him to set it conservative. I could be wrong, but I thought the spark map is all relative to the ignition offset angle set in the trigger wizard. |

WUE numers also dont have a 100% value, i beleive this means u will always be in WUE with the last value u have (106%). Can someone smart confirm this please :).

That in my understanding is not a bad thing to do (as I said before) - you can change the AFR target table without big changes to the VEtable (because the AFR is included in the fueling calculation.
sure, but do it AFTER you tune the VE table. |
