Havent Logged In Ages

[A4ringedONE8T]

Havent logged the car in over a month so figured I should make sure everything was still in check. Just with my luck, blow an IC hose off while doing so

24psi, T6, 12.1-12.2 on the wideband



Also saw this on my way to work, first one Ive seen in person. You can also see the lovely outskirts of Hurricane Ike

ever figure out why it was going lean?

Fuel pump

[IronAudi]

what is that in teh pics, ive never seen that before i dont think

[dougyfresh]

Fuel pump

Did you put a new one in yet?

[notob6]

its the new skyline.

[absolutegtr]

Im still not liking the looks of the GTR....

[A4ringedONE8T]

Did you put a new one in yet?

Nope

[Don Supreme]

Logs say the engine is happy (less lean condition), but as per usual the timing is anemic.

[edwardabodnar]

Yeah I am not in love with the look of them either compared to the R32 and older ones. I aw one pulling outta BK the other day for my first sighting. From what I understand though they are one of the fine breeds to drive

Definitely can run more timing with this turbo, especially on lower boost. I'm trying to figure out what Im going to do with the fuel system, need to get back to my daily 27-28psi!!!

[A4ringedONE8T]

And Ive got too much fuel but not enough ... explain that one

[mike-2ptzero]

And Ive got too much fuel but not enough ... explain that one

The pump is just moving more fuel now so thats why the ecu is trying to pull so much fuel back at part throttle. Your tune is set to run at 12.1-12.2 so the ecu is going to adjust the injector pulse to hit that, so the extra flow of fuel isn't going to effect that at all.


If you add more timing you should see the part throttle fuel trim reading drop a little, you can also pull back the main fuel to reduce it more if you want. At WOT you should still hit the same 12.1-12.2 since thats what the tune is programmed to hit and only way to change that is to have the tuner increase the target AFR at wot.

[A4ringedONE8T]

Well if my lamda is at -25, I dont see why the car is going lean above 23-24psi. Do I need a fuel pump or not? I thought we had concluded that I needed a new pump. WTF is up with my car if not

oh, for some reason I thought you had a upgrade pump. LOL


Since you are still running the stock pump, your high fuel trim readings are caused by a bad tune and your lean issue at high boost is caused by a lack of fuel supply at WOT and not allowing it to hit its target AFR. You can pull the fueling back and add timing to help with the fuel trim readings at idle/PT, but you are still going to have a fuel supply issue at higher boost levels till you upgrade the pump.



BTW, why are you blowing off hoses?

[Silence]

Why are you logging block 032 ltft? That's an adjustment over time, and really does nothing to log it during a pull. Just something that you want to check periodically. Timing on the other hand, needs to be bumped up. I'd bump it until you're pull 5 degrees or so in a cylinder. Try timing 7 and then 8 next. If neither seem to make a difference, add about 3 degrees in lemmiwinks and see what happens.

[A4 TSCHUSS]

for some reason Shawn cant run dick for timing when running over 20psi range. I was always able to run timing 9 on my car while boosting 21psi with the gtrs and that was while using the ecode front mount intercooler too which is much smaller than his (both of us using meth injection though).

[Silence]

Do you guys have the same kit, and nozzle size? That could make a huge reason.

[A4 TSCHUSS]

Yes both have Snow Performance and both run the 375cc nozzle and it doesnt matter if I run 4 bottles of HEET with water mixed or just -25F washer fluid from wallmart or the old RainX orange washer fluid that we all used to run I can run T9 on anything.

[Silence]

Weird. Have you ever tried using something like a vp m1 and mixing with water?

[A4 TSCHUSS]

no, I was told recently to use straight Denatured Alcohol though, supposibly it works awesome allowing more timing.

[Silence]

ya, they sell that at hardware stores.

uhhhh not to be a dick, but no shit. Dont you think I know that ...

[dirtybrd]

Iv'e been wanting to run an alcohol/washer fluid mix, to keep the flammability down.

[Silence]

uhhhh not to be a dick, but no shit. Dont you think I know that ...

Uhh I would think you do, but then again, it wouldn't be the first time you learned something. 400whp with a 3071r ring a bell?

It was merely a suggestion, no need to be a dick. The fact that block 032 is in the log is questionable alone.

Now, moving on, the reason I suggested lemmi is I haven't heard of you ever trying to bump up timing using that instead of the sps3. There's no reason your timing shouldn't look better, runiing lower boost and meth with 93 octane. If you have tried lemmi and logged before I apologize, but never seen you post about it.

Reason for the 032 in the log, I had it on 31, bumped it up as I was leaving my neighborhood this morning to check the lamda and forgot to put it back to 31 before I jumped on the highway and hit start (less than a mile from my house). The timing shown is limited by the T6 its set on. Its not going to run more just because it can without being on a higher timing setting. Even T9 only runs 11-12 degrees in boost FYI

[A4ringedONE8T]

And 400whp with the 3071R is possible, just with other shit and big octane

Ok, makes sense then. I know it won't run higher without being on a higher setting. (Remember, I was the first person with revo BT software other than Sarabi)

I've seen you change the timing with sps in previous logs, and it not make much difference. What I am suggesting is to trying adjusting your timing with lemmiwinks instead. It changes it across the board, so maybe just try using timing 6 and bumping it 3 or 4.5 degrees and see what happens. Just a thought. Figured it's worth a shot.

It only runs 11-12 with zero CF readings or is that with readings of 6?


Just seems like you need to just add more timing with the lemmiwinks on any of the SPS timing settings.


BTW how much timing CF are you getting when the car starts to lean out up top while running more timing or more boost?

[Silence]

Ya, I know that. Pump gas was the discussion we had in the past, and I suggested the 3076 to you. Hell, I even wanted you to get that 3040r in the classifieds a while back.

[mike-2ptzero]

The 30/40(aka 3082r) isn't nearly as good of a turbo as the GT30r. Its almost as bad as the GT2876r(aka 25/40).

[Silence]

I agree for this motor. Although there was a guy running it on vortex, on his built 1.8 making good power out of it. His name was Ian IIRC, but this was a couple years ago.

It goes up a degree or two with each SPS timing increase up to 11-12 on T9

Way back when (with the GTRS) when I ran a 93/100 50/50 mix, on T9 there were 0 CF's and 11-12's for timing

25psi, 13.1-13.2 on the wideband, T6

You are not running any real timing post 5k rpm... (After torque peak)...

Hence, no HP.

If Revo really tunes for 12.1, its no wonder they can't run any real timing on pump gas.

Out of fuel. If T9 doesn't give you enough timing then you need to add more using lemmiwinks, greg does it all the time.

Higher T setting doesn't always mean more adv timing, each setting has a different timing curve. This means you need to find the best T setting for your setup and then add more timing using lemmiwinks, do this till you get some low readings on a 1 gear pull and then see how high they get when going thru 2-3 gears. After that you can add more to max them out during a 3-4 gear pull while still having low readings during a 1 gear pull.

Odd that log doesn't even hit 5k. It wasn't like he was running straight pump gas, for anything more then pump gas most people have to end up adding more timing using lemmiwinks. Even that VW guy had to add 5+ degs of adv timing for his Uni file while running W/M injection. When greg runs high octane unleaded race fuel he ends up adding more timing with the lemmiwinks on top of his SPS setting.

[Don Supreme]

I have also added timing via lemmi - BIG POWA!

[dougyfresh]

I had to take some timing out via Lemmi because my timing curve was just a bit too aggressive on 93octane, 100degF ambient temps and 2.0L (file was written for a 1.8L).
