Keeping you all updated

For those that care or following my progress...

Installed the new clutch. Went with a Sach's "2.5" but Sam says it's not technically a "2.5." I can't remember what he called it but apparently the disk is a much more aggressive material, I believe.
Anyway, car drives like a dream! I ended up installing a new accumulator Vs the GT2 conversion because I've been reading threads about people regretting their decision to do so. Peddle pressure and such.
On to what you care about.
I've finally be able to get into it with all the mods installed and logged my first run. It doesn't look good. I'm running on the ragged edge of being dangerously lean.
Sam and I are going to try a few things and go from there. I have some deliveries happening this week.
I'll keep you all posted.

I attached a log. This is my 93oct tune. In its current state I don't dare try my 100oct tune

Ya a/f is sitting around 13 at full throttle. That's pretty lean. Most guys like to tune 11 to 11.5

Oh yeah 13 is flirting with disaster. Thankfully, the car hasn't started pulling timing. I'll be happy with high 11's.

Your injector duty cycle is 118% and you have leaned out your car real bad. Knock and pulling timing doesnt matter in this case and could have done damage. I would stop driving the car. Already there has been 2 blown engines last week on here.

Just because you dont pull timing doesnt mean you have not done damage to the engine.

Your short terms are way high at 1.24 which means its trying to add fuel but you ran out of fuel pump and injectors.

Your intake temps are really high too which means you need bigger intercoolers.

haha, The car is running leaner but hasnt "run lean." 13.0 doesnt mean damage has been done but prolonged exposure could get things really hot, fast.

My intake temps are registered in Fahrenheit, so I'm far from hot. Not to mention it only climbs 10 degrees with over 1.1 bar on stock K16's. They're doing their job

What is the temps outside there?

You could have done damage since you have been flooring it for awhile at 13.0afr. You will not know until the parts that got damage will get weaker and weaker.

Heck its 55 degrees out here and my intake temps at wot are in the 80 temps.

Nice talking with you yesterday Rich. Definitely think we need to give the fuel system some TLC especially considering that she was in the high 11s several months ago. Very good job monitoring your car and being on top of it! We will get it sorted.

Please stop, your posts grow tiring. Those are my IAT's. THATS WHAT THEY SAY! I POSTED THE DAMN LOG!!!!
The chart clearly states "F" and you can clearly see I'm at 100% throttle. What more do you want?
I'm not in Atlanta. I'm in Baltimore and the OAT was 29 degrees F Saturday morning. I'm running 4.5" intercoolers.

Read your first post. Why would you post knowing your car is in bad shape? Thats asking hey look at my logs is this bad? Stop working on your car and bring it to a shop. Your going to cost yourself 20k in a blown motor.
