i got dfco enabled now...

i have another question. i did some ve tuning, and had my ve looking good. afr error was in the 1-2% range... then i enabled the maf, and turned closed loop off. the ve...

i added lots of spark down low(13 degrees in some places) and holy crap the car is so much faster now.

anyways, what do you mean by closed throttle fueling? i dont understand what that is. do i...

also, i still have a surging idle problem. its quite annoying, and i dont really know what to do about it. rpms will drop to 500, then bounce up to 1500, then drop... rinse, repeat a couple times....

i turned it off, and now i would like to turn it back on. i have copied all the values from my stock tune, yet i can not get the car to enter dfco?

also, i can not get the air system to "be ready"...

car is still doing it... although not as frequent. now, sometimes it returns to idle perfectly, sometimes it hangs at about 1150rpms, and sometimes it drops down to 500. really driving me nuts. its...

i did a VE tune in open loop, and it took care of quite a few issues. the table was off. i did have trouble hitting all the spots on there though... i might be dynoing the car saturday, so if i do...

yes, i am using a plx wideband.

oh... i would not change the knock sensors sensitivity then. maybe a batch of bad gas? it could be so many things with no mods... you could also be running lean during PE... do you know your AFR?

but if i change the values by 2% to take away 2% of the maf value, it ends up being too lean. would it be safe to say the VE table is off at that point? im not even going to try to dial in the VE,...

mods? and maybe try removing a degree of timing and see what happens. i was getting random knock with my higher wot timing settings, dropped the problem areas down and knock is gone now. i did not...

also, if you are dialing in your MAF table, what would be the best guesstimate or however you want to say it, at how much in AFR does changing the maf table by say like 1 full gram equal...

like...

just wanted to give an update... i think i have fixed my clutch in rpm dipping issues. when i would be rolling and clutch in, rpms would drop to 450-700. my commanded idle is 875. anyways, the VE...

yes, i used russ k's idle config and copied those values into my raf table. i can do it again if needed, or i can post those logs when i get home.


also, i can not get the readiness tests to come...

throttle cracker is 0... disabled. follower airflow is also 0 for the entire time i scanned. its not that. it is doing it more often then not too.

ok, will report back later today. thanks for the tips

ok, i turned closed loop off on the highway, and dialed in the ve table. boy it was way off. anyways, i have it running "ok" in open loop only. its not perfect, but it really needs a dyno so i can...

ok, here is a drive scan from my way home from work. now, the stft's are all jacked up at first because i forgot to reset. i reset them on the highway, you can clearly see where. however, now they...

its a 2001 Z06, and i basically looked at 12secss's tune file for his fm13 and copied the timing tables, minus 2 degrees all over. i am sure i can use more timing in other places. not to mention,...

i am going to try to post a log, just have to figure out how to get it to this computer without my flash drive. fueling i think is ok, it could have too much. i have it running stoich at idle. i...

you will need a convertor box to run the low impedance injectors... you know about that right?

ok, well here is an update. i picked the car up from the shop, who fixed the active handling thing. i did some logging on the way home. and had my MAF RTT enabled and made some changes on the fly. it...

bill, i have not changed injectors. they are the stock Z06 injectors. i will start over and retune saturday. ill just make a day of it. ill start back at stock, and use your config. hopefully this...

i havent messed with the maf under 7000hz... i only change the maf for WOT the rest i just change the VE table. when i turned closed loop off via the VCM controls, my afr instantly went to like 18...

oh, ok... well i tried what 5 liter eater said about open loop only... that went horribly wrong. my idle at under 1500 went to about 19 and it ran like complete shit. i could barely get the car to...

how do i get my IAC position down to where it wants to be? it says 310, but the desired is 152... did a cold start idle until 198* and filled the numbers from the histogram into my RAF table. im...
