Here is the other log I did just before the one posted above. They are very different, so I will be getting some more logs on the car in the next couple days for use in tuning.

 

ur getting some knock and the injectors usually go static at around 120%, seeing that you already changed your fuel pump u can probably get bigger injectors.

and lean out ur maps on top and richen up ~3000 to 4000 rpm and you will be on ur way.

not sure why u would need new injectors though i am pushing 25 psi @ peak and tapering to 22 @ redline on my IX and my IDCs are 95%, not sure if the JDMs carry bigger injectors? my injectors are scaled to 552cc/min.

 

so u are still getting lots of knock? what is your boost by 7k?

 

No, I am not getting that knock anymore. I think it was logging something wierd as the file was pretty jacked up.

I am just trying to get everything else dialed in now. I think that scaling my MAF will help get the IDC's back in check and also allow me to get more consistent AFR's as it is adding about 10% on the fuel trims.

 

good to hear bro, think it were the sparkplugs??

what are your IDC's up top? i am running 22psi at redline and my IDCs are 97%. i find this pretty high?

 

Mac -- I think your tune needs some serious work. Your timing is way off (@3K you should easily be able to run more than 3-4* and @7K you should be 13*+ on ~94 octane). My guess is your MIVEC map may also be off as well. You might want to compare your MIVEC first to some of the maps posted on evom and then add timing and then finalize your AFRs. Good luck

 

He's fine.. The map looks good. When youre building boost you will see high timing numbers till you reach the desired boost level.

 

My MIVEC map is based on the JDM map and the timing will slowly be bumped up until I see knock. Then I will drop it down 1-2 counts. The fuel maps are off right now, but I just got done freeing up the airflow, so I expected that. It doesn't help that the maf scaling is off either.

I will post up some logs and maps when I start getting things closer.

 

Okay, I have another question. What would be causing me to see such high IDC's with the minimal mods I have? I keep seeing where people are pushing the stock system much further and I really don't think I am anywhere near that point yet with only some porting, TBE, and open filter.

Boost leak maybe? MAF scaling shouldn't be it because that is only closed loop, but does it affect the IDC values I am seeing in EvoScan?

 

Some points to consider:

1. Your AFR is a bit too lean in the 3-4k area.
2. You should most definately be able to run more timing and boost on 94oct.
3. Evoscan does not log IDC correctly, I assume that is what you are using?
4. Check for boost leaks.
5. What boost control are you using, that can make a difference on if you are out of fuel. Judging by your JDM map you shouldn't be, and I assume only holding 17psi means you are using a MBC.
6. People have had similiar problems from Walbro's and it was due to misinstallation. There are a few how-to's on here I would dig up. Mostly just reuse the stock components on the Walbro.

 

i agree with dbsears. check your walbro installation.

or in fact re-install it.

use evoscan 2.5 it is better at giving accurate IDC's

 

1. I will smooth that out a bit
2. That was the plan, but have been doing baby steps since I had the issues early on (which are gone now).
3. Good to know, that my be the problem
4. Was definitely something I was going to do.
5. Hallman MBC
6. I think the problems are now gone and I basically pulled the pump out and put it back in the way I had it. Maybe it just didn't seat right on the first install in the housing but who knows. I did just re-use the stock stuff on the Walbro though.

 

2.5 is what I am using.
