Help with datalog need a few pointers
What gear did you do this pull in? Looks like second gear by the quantity of samples.. Third gear pulls are usually what I use to analyze data..
Ok.. assuming second gear pull, with average humidity and at sea level.. that pull should be around 262whp and 243 wheel torque.. Compared to a stock Evo, thats about a 30whp gain..
I used Data Log Lab, 2nd gear pull, #2 smoothing, No correction (Standard Sea Level/Humidity), 300lbs ballast and stock sized wheels and tires.
So far these numbers have been fairly accurate..

Yeah it was second gear. I didn't really have a place I was comfortable to drive in 3rd to redline. I have been playing around with the maps and noticed a pretty good gain over stock with just fuel. I definitly need a WB. I might borrow one soon so I can tune it and get a good fuel map. Those graphs are prtty nice. What program did you use for it. I have tried graphing a bigboogiemans UCC but I can figure it out.(and i haven't tried very hard)
Those powor gains seem ok I wish it was more but what can you do
It is probably a little less since I am up here in SLC, UT.
I will finish my map and most likely send it to you so you can check it out.

Ahh, Higher altitude, probably pick up about 10-15whp with correction, however correction #'s aren't always accurate for turbocharged vehicles at altitude...
I used a program called Data Log Lab www.dataloglab.com Probably one of the nicest analysis applications out there for the money.
For one reason or another, your log didn't "digest" 100% on DLL, I lost the MAF and IGN columns (stock) but it does work with raw logs..

Hey Jack do you think you could run my log through DLL and see what numbers it comes out with? This is a 3rd gear pull with 93 octane.
Thanks

Not sure if your data was "Tweaked" to exclude fuel/timing and afr's (The data was altered) but here's your plots..
Smoothing was inadvertantly left at 5.. The graph should actually be a little higher in peak hp, 300lbs ballast and stock wheels/tires and no correction for weather/altitude..
Your power curve CLOSELY mimics mine.. Nice aggressive timing with no knock, comfortable fuel curve (by the injector duty cycle assuming stock injectors, it appears about 11.6 at higher RPM)
Anyway, 292whp and 278 wtq (with smoothing set to 3)
I want to point something out, if you look at the injector % curve, see how it looks compared to the RPM curve? The spacing is pretty even? Thats how I can tell a good fuel curve that is consistent for the demand of the engine.
Please tell me that you've had the car at the dyno and these numbers are close?
Also notice the anomolous MAF reading, looks like an aftermarket MAF pipe..
Ya know, this looks oddly like the kind of fuel and timing curve that I'd see in a reflash..

Its hard to guestimate AFR's like this because it has alot of factors.. Aftermarket fuel pump would make it richer.. What is interesting is this does look like the data I'd see in a reflash, but it also looks alot like the fuel/timing curve that my car had stock when I ran 21psi boost through redline..
What boost are your running, and what mods do you currently have?

Good call on the reflash Jack. Im doing this on top of a Dynoflash. I dont have the A/F ratio in there because I logged it onto my palm pilot. I was surprised the Dynoflash was closer to the target A/F ratio then I thought it would be. It was around the low 11's high 10's so I just leaned it out a little more trying to stay around 11.5 or lower. One question I have about fueling. I added about 5% to idle to smooth it out and when I first start the car it is smooth at around 13:1 but then it always gets back up to 14:1 or higher. Is there a way to keep it below 14:1 to keep my idle smooth?
I dont have any dyno numbers yet as there is no 4 wheel dyno anywhere close to me.
Here are my mods:
UR 3" turbo-back exhaust (no cat)
Intake filter
HKS 272 I/E cams
Fidanza cam gears set at -1/-4
Walbro fuel pump
Stock injectors
Boost set at 21-22psi falling to 19-20psi

Nah, Open loop fueling only lasts until the coolant temp rises, at that point it will "learn" and hover around 14.7-15.3 when it goes back to closed loop.. the open loop corrections really are only for the cold weather when you need the "Choke function"
You can reduce cam overlap and improve idle, or raise the idle speed by adjusting the IAC Solenoid on the throttle body (I think its a small alan key adjustment on it) You can adjust the ignition timing a little to smooth it out, however once it goes back into closed loop it'll run like it is now.. GOod news is it will get better as the ECU learns its trims.
The only way to completely get rid of the lopey idle is to reduce your cam overlap, -4/-1 will put 3 degrees additional time between the cams and reduce the overlap slightly, it should improve your vacuum at idle and smooth it out.. However that will also lower your peak HP # RPM by a few hundred RPM

Ok I was doing some datalogs from me going up a canyon. I was hiting the top of second and coming off the throttle for a turn. The it feels like I hit boost creep(i felt this in a sti but that is the closest thing i could think of to it). The whole car shook and lost power. No cel no knock. I put an arrow at the section I think caused the problem. Do you guys see anything weird here. I also think this could be caused by my VTA BOV. Thanks for any help.

It was a sudden jump in timing.. when your off the throttle, the ECU advances timing, when you got back onto it, it suddenly applied 8.5 degrees of timing from 31.4..
I don't recall seeing a decel-timing compensation feature on the UTEC where it would either use stock timing in that circumstance, or average the timing instead of jumping directly to your timing in the cells..
However It does look like you got a bit of compressor surge, so you might have to adjust your BOV a little..

Dang that could be very dangerous. If I was hard into the corner and that happened it is posible that the tires could break loose and send you off into a ditch. dang maybe i should make a canyon map that is all ecu timing.
Also what does LCM in the boost mean. The utec is not controlling my boost so it doesn't affect anything. But it is bugging me.

Not sure what LCM stands for.. I haven't focused on that deceleration type of stuff, but I think if you look at the Load site, and RPM, you'll see that the portion of the map its in is set to ECU, as soon as you get on it, it goes up to the next few cells, jumping back into the set timing..
Yeah i noticed that. I the car wanted to advance timing alot more than my map did. There was a jump in timing right there. Not very smooth. That is what i believe to be the cause of the stumble. I will have to turn that map back on and do some more adjusting.
