Here is a log of a 2nd and 3rd gear pull i just did.

http://www.skidmore.edu/~a_blaker/Logs/Run%201/

In this directory you will find an EvoScan Log and also a zeitronx zt2 log.
There is also a full 3rd gear log in the directory also

For your reference my boost is spiking to about 21, and then creeping up to 22 before it settles down to around 18-19 at redline.

My fuel maps are totally maxed out after 6000 rpm, and I also have a walbro but can not seem to get enough fuel. (stock turbo and injectors)

Please let me know what you think, I have lots more logs if there is something else you want to see.

Here is my power graph

Why do you think it's not getting enough fuel? Can you post a jpg or something of the A/F for the run? It's not knocking up top but it is knocking around 3500. I would either pull some timing from 3k-4k, add some fuel, or both.

The timing on the top end looks pretty conservative relative to what I'm running on my 05 VIII with crappy gas. I looks like you only had 14-15 degrees near 7k; on my car at least, I'm running about 17 and even that's really low. I think some guys are running around 19 with 93 octane or so.

Oh yeah.... it's really freakin cold where ever you are!

9's run much less timing up top than 8's.

Couple things.

You are running 122.03% Duty Cycle at 7000rpm. You are either out of injector, something is wrong with your car, your tune is off, or you are out of injector.

Your load curve is odd, probably because of your creep. Why are you boost creeping with your stock turbo? Upgrade actuator?

You are running 111.59% Duty Cycle at 5812rpm. You are either out of injector, something is wrong with your car, your tune is off, or you are out of injector.

What are your mods?

I get creep because of the ebay 02 housing. I could be out of injector but I have a IX with basic bolt ons, I have asked around and many people with my mods have plenty of fuel left with stock injectors. I think something must be wrong with my fuel but I don't really know what.

I have exhaust, 02 housing, FMIC, intake, MBC. Thats it - could i really be out of injector. Running 12.0 AFR to me up top seems a little lean, what do you think.

Also, I am getting knock around boost spike area, but my afr is 10.8 and my timing is 3 or 4 degrees, seems like I really should not be knocking there with that AFR and timing.

There already is a pic of the zeitronx log which has boost in it also. I also posted the zeitronx log file, if you download their free software you can view the log.

I think you have a bad fuel pump. I have read about some instances where the Evo 9 pump is not up to the task. I think that is why your IDCs are @ 122%. Install a Walbro and see if that helps.

I have a Walbro pump, and running about 11.2:1 at about 6000 RPM (by choice). Then when the IDC hits about 94% the injectors appear to go static and the AFR just dips into the high 10s. This is at 22 PSI at 6000, about 20 at red line. If I run a bit more boost the IDC is at 100% and the AFR stays just leaner than 11, but I can't run the timing if I run more boost on equivalent to 93 PON.

IX JDM/UK, 3" catless exhaust with stock O2 housing, Walbro, HKS panel filter/airbox lid mod, HKS hard pipes as standard on FQ models.

I gather it is common knowledge that even with a Walbro on a IX with an exhaust and induction mods you will max out the stock injectors at the top by running the turbo to a frisky but sensible 20-22 PSI at the top (or run near enough that they go static as my case even without a 100% IDC - ie a DC signal going to them), but not running 12:1 AFR.

Check fuel pressure at the top end under load?

I have a walbro pump (and 3" exhaust w/ HFC) and am seeing 98% IDC at 7400 RPM in third gear WOT but no knock....Load is reported (Mitsulogger) as 213 and timing 15*.....I believe boost @ 7400 is ~19psi (at redline it is > 20psi)....

I too have wondered if I need more injectors, but seem OK at the top end and need to still richen (or pull timing) just a tad between 3 - 4K as I get 1 - 2 counts of knock....

This is very interesting. It seems that the 9 runs out of injectors sooner than the Evo 8 does. My TBE Evo with Walbro logs a max IDC of 88-89%. I do not recall ever logging higher than that.

According to what I have read a lean AFR would lower your IDC and a rich AFR does the opposite. For those who are running high IDCs and do not want to cross the 100% mark, try leaning up the AFR a bit to lower your IDC.

Edit: corrected my mistake

jcsbanks

A rich AFR would increase your IDC and a lean AFR would reduce it.

What boost do you run at 6000 - 7000 RPM nj1266? The compressor housing is larger on the IX.

What is the cheapest way for me to view my fuel pressure at redline?

SophieSleeps

iTrader: (19)

My map is much leaner and my AF ratios are much richer than yours.

Running at 120% duty cycle with a walbro seems kind of weird if you're running nearly a 12 AF ratio.

Is your wideband calibrated correctly?
If it weren't, that could seriously explain why your logs look the way they do.

I think the max duty cycle I've hit was 90...I have an intake and a testpipe and I shoot for 11.5 AF across the board. Stock fuel pump.

Borrow a friendly mechanic's gauge and run it in through an open window.

It should run 3 bar plus whatever boost you're running.

dudical26

Yea i suspect something is wrong with the pump or fpr or something. The wideband is accurate as I have confirmed the reading with two different widebands.

I don't really know any friendly mechanics, maybe there is a friendly board member with a gauge.

I was looking at fuel pressure gauges, where do they hook in, seems like it would need to go between the FPR and the fuel rail, but they are bolted to each other.
