Sorry that was a typo. Map 6.

Most recent logs, trying to dial my car (DSG Alltrack) in and the outside air temp is playing a huge factor on my timing. Peaking 16 psi at 4000 rpm and tapering to 11.5 psi at 7,000. Only modifications are an AFE drop in and CTS turbo inlet pipe, this is with 93 octane

Let me know what adjustments you guys recommend, thanks

Here are two more logs, both with the same settings, peaking at 17 psi and tapering to 11.5 psi, first log is done with 80* outside air temp and the second is with 58* outside air temp

Looks pretty good. Based on timing, IAt and knock, I think you are where you want to be. You can also cut out the vents in front of the airbox and hopefully you pulled out the snow grate when you did the drop in.

Engine is going to get built so if anyone has found stronger internals for them post away.

Log attached of when it let go.

Any updated news on what cause the motor pop

I'm guessing it was the 17 degrees advance combined with 24 psi at redline on an is38

Not really sure. At this point my opinion is the injector in cylinder 1 failed. The piston seems to have melted right through on the one side. The rest of the cylinders look perfect.

Stock or R injectors?

R, got a feeling a used set was fitted as well.

This isn't Chuck G's SW right? I saw he ran an 11.44 a few weeks ago.

Just curious why would you choose to build a 1.8T? You're going to spend a lot of money to wind up with an EA888 Gen 3 that will likely grenade again due to the crankshaft. It's a cast crank with 48mm bearings compared to the 2.0T's forged crank with 52mm bearings. Huge difference. Why not just swap in a junkyard 2.0T out of an A3 or something similar? I've seen them as low as $1,000.

Lack of valve lift on 1.8T will make it a challenge.
Easier to swop in another engine for under 1000 and down tune it a tad. There aren't readily available components to build the engine.

It's a logistical nightmare. Harnesses, modules, and dash cluster need to be swapped, and a lot of coding needs to be done. In fact, the process still isn't perfected. MUCH easier to swap a built 2.0 bottom end in with a 1.8 head.

Has anyone ever done a 2.0 block with a 1.8 head on an EA888 Gen 3? I would think that would be even more work due to the head to block specific differences.
