GT2871R Log Discussion

**GarbatyA4** · 10-23-2008 06:59 AM

Hey All,

First time logging and posting a log. I could really use ur help.

I am on shitty mika tune still... 440cc bosch, FMIC 2.5"Piping, Full GT2871R, Neuspeed exhaust... Running 15psi.

Let me know what you guys think.
oh by the way, there are no correction factors at all with Mika Tune (never move from 0)

I think the A/F is too lean... my Primary fuel term is plus 25%

I think my injectors are maxing out?

What else am I supposed to log? What should I do?

My MAF is pooched right now

looks fine to me.

hmmm post actual logs with the link in signature so I can do some calculations.

Fix your MAF first. 25% correction is about the most the ECU is capable of.

Fixed the maf last night, my 032 values are within 5%

Sample rate was better, logging fewer blocks. Logged 031 and 003 also 115 (boost pressure)

Anyways, here's some 15psi logs.

I know i have boost leak issues hence look at the graph.

Anyone know how to save the excel graph's as higher res and bigger?

If someone could tell me how much timing I could push that would be great!

i don't think my tune has correction factors, So i'm just watching my knock sensor voltages, trying not to piss them off. I don't go over 20-22V

When under load, I'm reaching no more than 10 degrees of timing. Whats an agressive tune? 16-18 degrees of timing?

CAn you not access it?

Good that you fixed your MAF. Now fix your boost leak. Everything needs to be working correctly before you get into timing advance.

huh? no that does not work...

Go to the website

http://vagtuner.dynalias.org

Click browse, find the log on your computer and upload it.

It will then give you a link to post in this thread.

Be sure to only upload the full throttle section of the log.

Fixing the boost leaks tommorrow... Anyone have an idea on what RPM's the GT2871R should boost?

We cannot access your hard drive on your local machine. You'll need to upload the picture somewhere like photobucket and then add THAT link to your signature.

with your setup you should be seeing 15psi by 4000rpms in 3rd gear. 4th gear it will come on sooner, 5th gear even sooner. 9-12 btdc's is about normal for our off the shelf tunes. That is where I'm at. Aggressive would be upper teens to low 20's. I would not worry about knock voltages so much. I have been maxing mine out at 29V since 2005. How can your tune not have correction factors? I would not want to see BTDC's go below 5-6 at WOT in full boost.
