Enki's EFR Ordeal...

[Enki]

Have to post this... My prior attempts at soldering wound up being...well, abominations. They worked, but they didn't look like anything you'd want to be near.

This is the difference the right solder size and a good iron make; these are the two MOSFETs pictured earlier, now mounted to a board.

[littleloogy]

Its amazing how having the right equipment can make all the difference in your work. At work with high end irons, my work looks factory. At home... Well not so much.

I know it's been quite a while since my last real update; unfortunately, it's probably going to get more sparse from here on out.

While I was out testing the capacitor bank, my pops noticed something I had not.

My dipstick popped out just a little bit, spraying a little oil over the intake manifold and some of the radiator hoses. Nothing major, but considering I'm running stock PCV setup on the intake mani and the valve cover is vented to the intake, this doesn't really bode well; especially considering my AFRs frequently shift pretty rapidly when cruising between 14.2 and 14.9, steady state.

With as much abuse as my car has seen, I wouldn't be surprised if it failed a leakdown test on cylinder 3 due to ringland issues.

At some point in the near future, I'll look into doing compression and leakdown testing to see where it stands. Unfortunately, the last test I did wasn't really conclusive, so I'll probably have to borrow one from a local.

[Enki]

So some of you may know that there's been some testing going on with a potential fix for full E85 found by @littleloogy;; since his testing has gone rather well, I asked him to post up his findings so we can branch out the research/testing to other owners willing to participate. I have to admit, this prospect has me rather excited despite the fact that I can't really run full E85 and hope to hit stock boost levels.

That said, I went ahead and decided to test anyways. I picked up the last two bottles of this shit:

Sad Christmas. Pressure went in and out multiple times, including having only ITFP pressure upon cold start. I'll pull and clean the pump, but if it goes out again after that I'm afraid I'm done with the testing; hopefully others will have better luck and my car is simply cursed.

Logs and vdyno attached.

[littleloogy]

That's not what I wanted to hear. Yeah, clean the internals and see what happens. I am curious why your having pressure drop @ 50/50. Shit is working flawlessly for me.

I'm not on 50/50; 2 oz sauce to 1 gal e85 is what I have in the tank right now.

[PapaSmurf]

Possibly it only works with redline oil? Or atleast not what your currently using.

There might be some truth in that. I'm on RP oil, but other oils are going to be (or currently are being) tested.

[littleloogy]

What flavor E are you running? Do you think one brand can have a different effect on oil then another brand? I have not had sticky internals until I went on this road trip. Maybe my car got a STD form all the different pumps.

Shell pumps/store, Western Petroleum. Neighbor down the street says when he hydro tested (using the mix and shake cylinder tester thingy) one of the pumps I frequent (as early as 3 weeks ago) tested at 85% ethanol by volume.

Houghton or Sahuarita?

Just tapa it in.

[littleloogy]

This makes me curious also. The ingredients could be different, sugar can also be used to make E. I'm wondering if certain brands make E differently, and with chemicals that react to oil better/worse with certain oils. Might have to put my chemistry lab coat back on...

I am pretty sure there is a company in the US that does supply Sugarcane Ethanol. Most is said to be corn, but I have heard from people that sugarcane ethanol is also available in the US.

hard to find which companies distribute to what gas stations etc.

Yes. Pacific Ethanol, Madera, CA http://www.pacificethanol.net/

I think he got his last from Houghton, I got mine from Sahaurita. Pretty sure my pump is at least half the problem though.

OK so, some interesting news.

First off, the spill valve was sticky as fuck; no real surprise there. What was surprising, however, is that the sticky came off without having to be actually cleaned out; simply handling the disassembled parts ended the sticking of the spill valve. Even more interesting is that normally, cleaning sticky death off of shit (using rags/paper towels) usually leaves your hands/fingers sticky as well. Not this time.

I did wind up actually cleaning the button valve retainer (the part you take out after the spill valve) just to be safe, since the sticky didn't rub off of that. I'm assuming it's because I let it dry, whereas the other parts still had corn on them.

As a result, my current observations/hypothesis about the Redline fuel injector cleaner are as follows:

1. It actually does a quantifiable "thing" to improve conditions that lead to the formations of at least the sticky death (long term testing needed for black death on the internals)

2. Your testing results *may* be skewed if you already have a pump full of sticky, since it can't seem to actually remove the sticky coating but can lubricate/prevent sticky interference from taking place (helps with already sticky cars)

I have to note that points 1 and 2, while carrying my personal thumbs up, may not be entirely accurate. The simple fact of the matter is we need more test data to either support or debunk both claims.

As a side note, I also did the spill valve spring mod v2, and it gave me some interesting results...It partially stuck in a position that forced maximum pressure development between shifts initially:



Yes, it felt as strange as it looks; like I had a new rev limit of 4k. It didn't do this every time, btw.

[Enki]

Well shit. Go get fueled up for the monthly trip to Phoenix. No problem there.
Flash back to E26 map since I still don't fully trust full E85 in my car yet. So far so good.
Go to check tire pressure, get up to the driver's front tire and the area reeks of fuel. REEKS. Fuck.
Pop the hood, check things out, bottom of pump and hard line is covered in fuel diluted oil. COVERED. No clue what's up, but I'm sure it ain't good.

Probably time to get a new pump and hard line after all, but tomorrow will tell for sure.

The only thing I can think of that would allow that much oil to pass would be the primary O-ring that slips into the valve cover. Those tiny little quad rings barely qualify as a barrier to oil. Hopefully that's all it is, sorry to hear the shitty news.

You mean around the valve cover itself? I don't think that's it as there's no oil above the bottom of the pump; there's a ton going down/on the hard line and a pool under the pump that I'll try to get pictures of tomorrow morning during some diagnostics.

I think he may have been talking about this o-ring. It's the first thing I thought of:

I have new and used hardlines if you end up wanting one.

[Chimmike]

hey stEnki. Why don't you have a check valve in the factory PCV system? That's why your crankcase is getting pressurized dude. Stock PCV can't handle the type of boost you're running, it's destroyed it.

[Enki]

Hey gingerbike, 20 psi is a lot? That's news to me, considering I was running that stock turbo (/sarcasm). I know what I need to fix that, but I don't want to spend the money or time to do it anytime soon.

On topic: Turns out it was the hardline nut (again). Torqued the fuck out of it and the area around the pump was dry after I got to phoenix; no new oil/residue or anything. Last time I tightened it, I was pretty sure I went too far and now I'm about a half turn past that. Gonna see how long it holds up though.

Oh and btw, this is what it looked like at 8 AM this morning:

Make sure the fuel does not splash on your BT, that would be no good. I'm glad you caught it! You could have had a bad time.

I'll be the first to admit that I'm complete shit when it comes to straight line racing, but I went out and did some spur of the moment today anyways.

Met up with a non-NATOR MS6 (Utah plates) belonging to a stepson of one of the SRT4 guys (former MS3 owner) that I've met since I started doing the whole car meet thing several years ago. Anywho, I gave him some basic advice on drag racing so he didn't break shit (he's almost completely stock, sans SRI and TIP) and he improved very rapidly. My second and fourth time slips have him in the right lane, for those that care; I'm left lane in every slip.

I've got logs and videos of the first three runs, but forgot to do the fourth as I was in a bit of a hurry. My goal was to get > 105 MPH and that's what I did; there's still a fair amount left in the car as far as power goes, and I'm confident that a *good* driver ( @udntknw; ) could easily abuse my car into the high 12s; though I'm not sure if that will ultimately require WMI (which I still need to finish installing).

At any rate, the car is running well, and even though drag strip shit ain't really my bag, it was entertaining.

Sorry, Enki can't hear you over the sound of his 400whp daily driver and soon-to-be 1200+ whp weekend car.

Should have the WMI install finished/wired and tested this upcoming week. Here's some pics of the BPV dissection from today; basically waiting for the RTV to set before I do anything else.

Nozzle will be mounted on the black blockoff plate in the first picture, which I'm aware isn't ideal but it will be sleeper with the stock BPV hiding it. I'll eventually get some hose on the outlet and probably finish the wiring before long.

I *do* need one of those vac blocks, though Full-Race wants $50 + another 30 ish in shipping so I'll probably see what I can get from Edge or another source.

[Enki]

Chatted with @Ziggo; last night regarding load tuning, figured I'd give it another shot.

Didn't go so well.

The only thing I can think of is the .95 injector phasing that's set on this map that isn't elsewhere; if this test doesn't go well then I'm probably just going to go back to boost tuning.

[Enki]

Made the change, tested it, still running low 14s AFR.

Compared MAF tables and realized that the load tune one was calibrated rich, likely to try to curb some of the leanness...replaced with MAFCAL from the destro tune, and tripled my boost overrun WGDC comp (underrun still zeroed).

Gonna give this one last shot...

[Enki]

Little better...Going to try dropping load target to 1.5 and see how it responds/runs. Not sure if I'll have time to flash and run today or tomorrow; might have to be Friday.

I know that high bats are killing my ability to hit my 2.0 load target, so I may not be able to without the meth spraying.

[Enki]

Think I have this figured out. I converted all load targets to 1.5, including dropping the Calc Load Max A and B to the same; issue got worse, and peak load dropped to 1.23 @ 20 PSI/almost 4 volts and 320 g/s flow @ 5k rpm...way, way off from what it should be.

I then loaded up the boost map and it ran like a champ; no issues.
Started comparing tables and came across the max load table which I guess I didn't comprehend fully what it was for and realized I was setting my own personal load cap, nor did I realize that this is what the result would be from setting that table too low.
I've got it set the same as my boost tune now (5.0 load max) so that should take care of it if I'm not totally retarded. Still not sure why it won't go over 1.23 load when everything else is set for 1.5 though.

Hopefully I'll have a chance tomorrow to test it out.

I'm still retarded, but this fixed it. Some more tweaking and I should be good to go.

[rtabagaboy]

Good stuff. I just started trying to load tune and everything is looking similar to my boost tune. Except I am not on E85 and things are heating up these days!
