Okay, I have taken three more logs. In the link there are three different logs, I suspect that the second two came out better than the first. If anyone could look at it and help me diagnose why I am missing boost andnif there is anything out of the ordinary on the log. I am running MHD Stage 2, I have VRSF Downpipes, Tial BOV with 8 lb spring, and DCI. Thank you

Dont spin it that high. It really is making best power at about 5500-5800, run it to 6200 and that will put it in the sweet spot in the next gear.

Boost is a little below target until about 5200. You might want to think about WG hoses and solenoids.

Okay, thank you so much. Do you think it would be smart to go stage 2 + after I get an intercooler or wait till I figure out the underboosting issue?
Also, does my fuel pump look healthy enough to handle ethanol? like an e40 mix?

I would do the IC and that will give you a chance to check all couplers.

I thought I saw it near 55.. prob needs a S2 pump..

My first log of my ST 6266 map 1 spring pressure should be 12 psi but holds 15psi. Checked all lines and everything is good. No kinks in pressure lines and correct routing but it’s steady and logs seem good. A few extra sets of eyes would be great before I try map 2 to see if it holds proper boost electronically with the mac.

What up Ecko. Can't tell much from this log. If you have these mods best to flash MHD STG 2+ for whatever octane you are running then take a log. Ideally you would get a custom tune or even a base map for those new hybrids because it won't run well without it.

Either way, floor it at 2500rpm (don't let it kick down) or so in third, then run it out and let it shift to 4th for a sec. Then post up and we'll take a look

Can anyone help me out with this? I took a short log here, during WOT I'm misfiring and then going into limp mode. So if you click on accelerator position and find where it's pegged to 100%, that should be the problem area. I've already got a HPFP replacement sitting in my living room from FCP Euro that I haven't installed yet, but I don't want to waste my time, because I'm not knowledgeable enough at reading logs to tell if that's the issue.

Honestly I think I could figure this out on my own given the "interpreting MHD datalogs" guide that I found, except everything seems different on my car/maybe because it's an N55. I don't even know which values correlate with the LPFP PSI, it mentions 2 banks each for fuel trims while my logs only offer "STFT 1%" and "LTFT 1%" and the same goes for the AFR which the guide mentions 2 banks, while my data only shows "lambda bank 1 afr." Am I missing something here?

Looks weird .. not sure what happens. What is the code? Just random cyl missfire? I dont see the LP value identified.

You might go to the MHD - FB page - they have a little more coverage - https://www.facebook.com/groups/1619...oup_browse_new

Not bad. Close to targets. It has a little retard on cyl 5 as you get mid pull. And IATs are on the way up quick. If you plan on going S2 maps you will need an IC for sure. And if you get a shift in there (from 3rd to 4th) the retards will prob be a little higher. Get ready to go with one colder a plug too..

Unrelated to your vibration, but your IAT looks like it's getting pretty hot, and causing a tiny bit of knock. Do you have an upgraded intercooler?

The vibration could be engine mounts or something.

Thanks, going to join that group and post on there! I did message MHD on Facebook directly and eventually they apparently looked at my log, and concluded that it was "perfectly normal" which I'm unsure how that's possible given that it went into limp mode in the middle of that log. Maybe they didn't look at it.

This morning the car started, sounded really rough, and then died on me. I had to give it gas just to keep it going, and then I drove to work without an issue.

So far it's just been misfire codes, I previously had seen some low fuel pressure injection cut codes.

Here is my most recent log. This was sitting at a stoplight and then pulling off in drive, not a very hard pull or anything. It does seem like I'm getting big timing corrections on all 6 cylinders:

No FMIC, got one ready to go on. Will fit that and do another log. Thanks for your input
