You better message pure turbo. They've done over 500whp on stock turbo. Mind blown.

on E50 or E85 +meth may be yes, i was thinking on pump gas. How many hp can get on pump gas (93octane/98Ron) & stock turbo???

Honestly probably whatever MHD Stage 2 OTS/BM3 Stage 2 OTS provides. Really can't do much on 93 only.

@Sµpreme that log looks good, right over target, interesting difference on the road, at most 0.5 PSI over, that is normal

Nice boost profile rising up top, until turbo runs out. Must to be close to the best you can do on stock. WGDC is smoother and does not peak up as as it did on the last one as well. I would be pretty happy with that.

wife used to run logs with me in my old car. now when i leave she panics because every time she assumes i'm doing 140+ on the highway

that log looks crazy. 25+ psi? I'd recommend less boost and more timing.

What will the timing do? Advance ignition? I saw sc_b58x had Meth detonation in their intake manifold, what actually caused that?

Since I had my misfire event on E70 a couple of weeks ago, I've seen this "Combustion period outside of tolerance" code a couple of times in the code history. Any insight into what this is and whether I should be concerned about it?

Timing will advance ignition, but you need more octane to go past a certain threshold. We seem to have no issues pulling 14°-16° on 93 octane, so I'd start there and then add boost until you run out of fuel. Going the opposite way (add more boost and less timing) tends to make less power.

The intake manifold issue was a fluke. Spraying meth + high psi caused the meth to ignite in the intake manifold. Kind of like how diesels ignite under compression. I wouldn't worry about it.

This is a shot int he dark, but you likely it hit the limit of our variable timing. You can only pull so much timing until you hit the physical limits of our cams. Did you log that E70 run? And is it still coming up now that you corrected the mix?

100% methanol autoignition point is at 700°F+. There is NO WAY it would ignite in intake manifold.

[baldeagleman]

Just got the NGK plugs in and gapped to 0.022" like everyone recommends. First log since

https://datazap.me/u/dparadis21/mhd-...data=5-6-19-44

Didn't have a great spot to do it so it's not perfect. Losing a bit of timing in the beginning, but it ends up evening out in the end. What do you guys think?

Well, I guess it happened by magic then.

Looks ok. A lot of us have lower timing on cyl 1, but it should catch up by redline. It may need some time to adapt.

35+ psi is no joke for a plastic mani. Some welded manifolds can crack open even at lower pressure.

Just playing to see what would be logged. Dinan Elite v1 93 Octane


Downpipe being installed and Dinan removed as we speak. I will then load MHD Stage 2 93 octane and post new logs

Any comments

I did log and post it when it happened on this thread, flip back a page or so.

I haven't run anything stronger than E70 since then but it looks like it's come up twice since then.

Edit: I don't know why but I can't find where I shared that now.

Australian 98ron is garbage apparently.
We are gradually turning it down to avoid timing corrections.
Looking forward to starting the ethanol map.

Fuel rail pressure drops between 2-3k rpm and 4.5-5.5k rpm

Minor timing corrections, cylinder 6 pulling the most.

it's easier for meth to ignite and cause the failure. Yeah it's a lot of pressure, but I've seen that (on other platforms) without issue on bigger turbo setups. Or he had a slightly weaker unit. But it shouldn't break under that kind of pressure.

Looks pretty good. MHD will target higher boost and run safer AFRs. Should be a nice upgrade.

yeah that's a strange one. everything looks perfect except rail pressure. it is a lot of timing really early though. I wonder if there's a software limit on how much advance can be added throughout the rev range? it's clearly something with timing. if it's just a soft code then maybe something you can ignore, or ask wedge if they have any ignition threshold parameters that can be raised to keep it from coming back.

Looks pretty good. I'm assuming from the log title you swapped to NGK plugs? Did you close the gap at all?

def add some ethanol to get that timing up. that's less than our 91oct maps

Good catch. I didn't even look at fuel pressure since it's an OTS map. Doesn't seem typical at all.

Gapped to 0.022". That was my first pull with them installed on that tune. It was also raining outside, so not really ideal conditions. Once they have a bit more time I'm hoping I can get those timing corrections down a bit.
