Hey, how does this look:

http://www.datazap.me/u/erttu123/sta...23-24-25-26-27

MHD stage2+ 95oct / xhp stage2
Running on ~E25
I ran out of road doing this pull, so rpm's didnt' quite get to 6000.
Will try to get a log done with higher rpm's,

Car is 2007 AT with 190k km's, basically stock except MHD Stage2+ 95oct and xHP Stage2. Getting timing corrections on some pulls, like -2.5 on two cylinders but not more than that simultaneously, usually on one or two cylinders. None on this log. Yeah I need to get an IC, however its quite cold in here soon as winter is coming and I dont do pulls that much, or I'd lose my licence. Ambient temps are usually around 50-70 F or less most of the year.. thanks

ST Trims a little high. After it gets on the rich side they stabilize. Try resetting fuel adaptions and see if its closer to single digits. If not, you might be adding too much fuel.

I would not worry about inlet temps much it does not sound like. I get the impression you rarely hammer it more than for 15seconds witho having to slow down...

Thanks, STFT's used to either go -34 or +34 on WOT, but I got it kind of "fixed" after I reset lambda sensors, octane, lambda regulation adaptations. So it was much worse before. Cant really do long pulls in here as max speed limit atm is 120 km/h and soon it is 100 km/h I was already going near 140 km/h on that log pull. Maybe the car is still adapting to the E25 mix..

Tell me about it, Finland sucks if you like cars, high taxes and everything .. If you already drive with e25 mix in the tank, why not try e25 map?

I tried E25 map but STFT's / LPFP were all over the place even tho I reset adaptations, also got more timing corrections, maybe not enough E85.. I calculated it by pump having actually E85, so might have to put in couple litres more and see again, need to get that E85 content test tube.. Might try it now again as STFTs are a lot better I did hit 19psi with E25 map also got overboost in one pull I think..

When I use E25 or my E30 custom tune, i fuel 20 litres of E85 and top up the rest with 98e5. works perfecly fine on both maps. Take a look.

Somthings defs wrong with my car i basically hit 15 psi on the e60 map and always 2 psi under target. Had a smoke test for leaks and came up fine, any way to tell if a BOV is leaking ? What do i look for in my logs to rule out things like boost solenoids ect ? Only dynoed 394whp best run on mhd e60. Thats aussie numbers though so probably like 500 american hp, just kidding.

Yeah, pretty good delta. There nice cool air where you are (ah, right down under). Have you done the vacuum line thing?> Id start with hot side first, and checking the one behind the OFH. I think the WGDC will show some stuff if vacuum to sels is not consistent (edit you do have a strange event with the DC at the top of the rpm - its tapering boost there but all of a sudden your DC drops quite a bit - see pic) . But you would like have to know what it had been normal to make sure. Logs can do a better job showing diverter issues bc they have to react to changes in manifold pressure and thats goes from +15 to -10 when throttle closes (such as a manual trans shift). A more drastic change.

Can you back down to a 93 map and see if the delta is as bad?

Car is stuttering badly during acceleration, originally thought it could be a boost leak but now I am not sure at all

Anyone else having problems with the Datazap site today?

I'm starting to get frustrated with my car and getting it to run correctly...

Here are my latest logs from today... The car feels like its breaking up/ misfiring at WOT but doesn't go into limp mode or throw misfire codes...
All my mods are listed in my signature, any help/advice would be great!

Not gonna work my friend. You need a custom tune if anybody does.

Your getting all kinds of over targets and closers.. do your WGs a favor and get an etune.

Even just looking after the shift to 3rd gear your got some really high boost targets considering the load. And the fact that your dont got any reading from your LF pressure sensor is a little strange..

Now that DataZap is running normally again, does anyone see anything in my datalog that sticks out?

Well, for one, you only got about 5 seconds of WFO.. I know DE is small but man.. we're gonna need a little more than that ;-)

http://datazap.me/u/wesley610/log2?l...zoom=1497-1535

Anyway, toward the end when you were in fourth it went back into spool so its kind of hard to tell what happend bc after that cyl 5 just starts pulling timing pretty bad. The others look ok. Most the other aspects look ok. Try to get something from say 3000 in 3rd to at least 5000 in 4th.. and not get jailed... Its not making a lot a boost but thats not surprising for the s1 map you got loaded. You are consistently hitting the load target so you should at least try an S1+ map. Thats when things get kinda crucial.

That's the thing, it's actually the 4th revision of a custom etune by a famous tuner who I'll leave a secret for now. 2nd gear I was obviously peddling the throttle because the tires were spinning, so 3rd gear is the one to look at. I can't do a 3rd gear roll from a low rpm or the clutch will slip sometimes. The 1st revision ran the best (pretty awesome actually) at 26-27 psi and didn't break up/misfire feeling, but I've been plagued with timing drops since day one. So I don't if something is wrong with the car or if it's just the tune...

Oh, and the Z4's don't have lpfp sensors

Haha much appreciated. I was mainly looking for sudden spikes just because the car has been misfiring so badly but still not giving me any codes. Trying new plugs tomorrow morning

[335e92tx]

theres no indication of a hardware issue. But, hitting the targets and when the DME does something drastic it can probably feel like someone just threw out a big anchor.

It's definitely doing something odd. Understandable on the driving, but it really doesn't help when looking at logs lol Pretty significant timing corrections in multiple cylinders on all the ones I glanced at. First map had some large bank-to-bank trim deviations and both were way negative. Bank 2 was full negative trim, but AFRs remained relatively constant at mid/low 12s. v4 trims are better, but AFRs are all over the place from 13s to 11s, presumably when it's breaking up. I've not messed with straight E85 or supplemental fueling, but if it's actually misfiring on TBI/PI, it's wise to be cautious.

1) If your clutch can't hold the torque, why tune it for 28+ psi when there are obvious issues in both running it and getting it to the tires right now? At least taper the boost/tq low to high to something your current clutch can handle through the mid-range. There is a lot of space between all and nothing. Get a solid, clean middle-ground tune and then dial it up to work through issues as they arise instead of throwing the kitchen sink at it. If you have enough pump, why not test a ~20psi E50-70 map with the PI turned off? You need to start eliminating potential causes one-by-one so you/your tuner knows what to focus on. First order of business should probably be to eliminate the PI until any misfires are cleared up though.

2) One of your log notes indicated a manifold o-ring blew out, you're sure none are torn and there are no boost leaks or other install glitches?

3) As far as misfires, spark plugs could be carbon or fuel fouled, too big a gap or wrong heat range. When was the last time you read them? You're sure all coils/wires are good, wires fully seated and appropriate settings are made for them in the map I assume.

4) Stock DMFW have been known to cause misfires on high HP cars IIRC. Not sure if that's potentially impacting you, but sounds like it's time for a clutch anyway, so might search a bit on that subject before you buy.

You've got a lot of stuff to make power, but it will take time to get everything playing together nicely and do that safely. Step back, take a breath and start slow. It's only v4, so a bit early in the process and if there's a hardware issue, your tuner won't be able to anything about it on their end either way, but if you're having doubts, there are plenty of high-caliber tuners out there. Don't be afraid to spend another couple hundred again somewhere else when it comes to the part that pulls everything together and either gets you 600+whp or puts the rods through the block. Hell, spend it 2 or 3 times if you feel the need. Tune is THE most important $$ you'll spend on it, particularly for relatively safe high power.
