Just changed before flashing. Maybe I need inlets to reduce it? Will it being high wear turbos faster?

Im definitely concerned about the MASSIVE post-shift timing corrections, as well as the car leaning out to over 20 AFR. Can anyone help me make sense of this? Has original O2 sensors, index 9 injectors, N55 plugs have 20k miles on them gapped to .020, original turbos, 85k miles Car is completely catless and has relocated inlets and was running near 43% ethanol.

Just trying to get an idea of turbo wear, mine ramps up to the 90+% initially which I believe is normal, and then drops to to about 40%?

Having misfires under light load on a brand new motor. It has been a while since Ive had a good log to compare this too but my gut feeling says injectors, tune, or HPFP. This log was taken with Test0 so I apologize that the axis are in the edibas value names.

Re log, I don't think anyone will be able to read this.

That is normal to see, for spool the WGDC% would be high then as you meet boost target it drops into something manageable to maintain the boost.

Saw this on another forum:

The DME attempts to target a particular boost level at any given point in time. With stock inlets, as revs increase, the compressor inlets have more and more of a vacuum present due to pressure drop in the stock inlets. The DME needs to close the wastegates (Apply higher WGDC) for the turbos to spin faster to make that target boost. Once upgraded inlets are fitted, there is less vacuum at the turbo inlet, allowing the turbo to make boost easier and make the target boost without needing as much WGDC applied from the DME.

Inlets will reduce WGDC, though you will need a custom tune if im not mistaken.
Turbos spinning faster to make boost target is never good.

Yes needs a custom tune to reduce base, otherwise ther will be throttle closures.
What you quoted up there, is the ratio pout/pin or pressure ratio of turbo, also called boost setpoint in the wgdc table. When the denominator increases (as a result of less vacuum at inlet) one can generate a higher pout (or boost) for the same wgdc setting...

Just installed the Fuel-it Stage 2 bucketless and want some opinions. The LPFP is hovering around 55 which I find kind of low and the AFRs hover around 11.8 which is kinda rich.
Mods are DCI, Stage 2 LPFP, FMIC on MHD Stage 1+ tune.

Here is a log of MHD STAGE 2+ , running 93 with 2 gallons of e85. I'll have a stage 2 bucket installed later this month

[dyllan12]

I'm about to go fbo and on E , stage 2 pump in and all ..... I'm going to install the monitor gauge .... Is there like a website that shows the the number range for each monitor if you understand what i'm saying ...

For instance

LPFP rang
hpfp range
oil level
and so on like what should be all the monitor ranges , because i want to make sure all my numbers are good just to keep an eye on it

You need it, LPFP pressure is in the 40's

Here's another pull but on Shell 93 with 2 gallons of e85! Is timing better or worse? If I plan to be on e30 later will I still need the additional 2 gallons of ethanol?

Can't comment on e30,

but the log you posted shows zero timing correction across all cylinders that's exactly what you want. Seems to be going beyond boost targets initially and then dropping about 2psi below at peak. Doesn't look drastically bad to me.

Thank you sir. A boost leak somewhere maybe? The vacuum lines are totally shredded lol

Pure600 Turbos, Helix 3X, Stock location inlets, stainless outlets, stock catback exhaust. VRSF DowPips.

Tuner is saying all is well. I keep wondering if it is problematic that the Target boost isnt being acquired? My tuner said that the target boost is a boost ceiling and not necessarily where it should be.

Car runs good, I just want to make sure i dont have boost leak.

Possibly, I'd replace all vacumn lines and check cannisters and Solenoids anyway.

[Pete’s335is]

Hey guys,

I got back into my car after not driving for a while and noticed some weird noises. I wanted to log to make sure everything was alright, and would really appreciate a more knowledgeable opinion.

The cars a 335is FBO with new PR coils, new plugs, new index 12 injectors.

I've been having a random misfire in cyl 3 but it never throws a code while driving, only shows up when I read codes with MHD. A few pulls were done beforehand and this was the cleanest log.

[Godzilx]

Decided to try out E85 today. Did a E30 mix on MHD Stage 1+

Was wondering if someone could view my log and tell me how the cars taking to e85.

Any thoughts greatly appreciated

Easy guys, can somebody have a quick look over this log & point out any nasty...
