Do you not understand that an injector receiving a 100% DC, and a "120%" DC are receiving the exact same electrical signal? To an injector that is the exact same thing.

Send me a log of one of your 120% DC runs, and I will replicate it in test mode. I need Pulse Width, and RPM.

18psi

iTrader: (76)

yes, I 120% understand that.

I will look for it. and the logs before and after showing decreased and increased commanded VE and the resulting leaner and fatter AFR's

its on my laptop somewhere.

it was with MS3-pro and latest TS version too

Well im really disappointed and a little bit confused. Compressor consistently surges at 14.5 psi. not 20, not 22.

Im sick of talking about it, and running it through my head, so im just going to leave these here and let you guys bicker about it and poke fun at me and another fail.6.....


I think it will make a little more if i get a dyno plot without crazy comp surge in it... still, shitty, shitty numbers









Saw this abortion today

definitely something wrong then. rebuilt turbo?

hi_im_sean

yes, see post 1 i think

What's going on with your AFRs in this graph? Do your logs look like that as well? I was having an issue where I was going lean at higher RPM and it turned out to be my fuel filter was pretty clogged up with some lacquered fuel from the off season.

hi_im_sean

Thats from the comp surge and fluctuating map. The "some of it" 10psi tune works great and is smooth. My highest IDC is 71% on the "14psi" tune.

Fuel filter has about 300 miles on it. Wix.

U sure its not miAresfiring?

hi_im_sean

iTrader: (3)

Im going to gap down to double check. But d585s bruh

18psi

iTrader: (76)

doesnt matter. unless you are 4,000% duty cycle sure it's not misfiring, I dont think its turbo. At least I never seen it do that. really weird

aidandj

I agree the misfire suggestion. Plugs were gapped to stock so like .04".

I also suggested blocking off the BOV just in case its fluttering or something.

hi_im_sean

iTrader: (3)

It just feels nothing like any misfire ive ever felt. This feels like someone is just opening and closing the waste gate at about 2hz


Got a log


Ill gap down and report back. Any other suggestions?

18psi

iTrader: (76)

try an mbc?

Is pulse width a function of MAP? It also looks like something is going on with your TPS signal as well. Although it doesn't correspond with any fluctuation in the MAP/PW. Does it do it at all when running only wastegate pressure?

hi_im_sean

iTrader: (3)

I think the TPS might have been me. not sure, but ive never had any TPS signal issues before. And i would guess the 2 spike on the lower left are AE spikes. Ill see if i can get some cleaner logs.

hi_im_sean

iTrader: (3)

yea, just looked at the log, those are AE for sure. Havnt tried WG, but doent have any issues with 10psi tune

aidandj

iTrader: (5)

Post actual log too plz

hi_im_sean

iTrader: (3)

sure thing, sweetheart
