GooseTuned Gen 3 - Baseline Dyno Runs vs Gen 2 Baseline!

[GooseTuned]

I literally got mine done a week ago with the stage 2 with the cobb intercooler and AFE intake. Makes a huge difference. The ECU takes 5 minutes to unistall. I have a e85 station around the corner. Thats next for me.

E85 (E50) is another HUGE increase in power

So, all that brings up long term planning questions for me. I see moving to the E50 tune in the near future and blending. I really don't have a problem with any of that effort. But then I think about a fuel pump and injectors... and an inline E sensor to prep for running E85. Does that pave to way for a true flex fuel capability? How many tunes would be resident to span the 91/E85 spectrum? Will the AccessPort be capable of that type of dynamic real time switching or will we be moving to a new platform?

Sorry, I had a 300ZX TT that was a perpetual 11 year project and was just about perfect with 528 rwhp when I sold it and started a new project. I know that doesn't sound like all that much HP today, but back in the day... Yes, I'm old.

That would be more of a question for COBB. The Accessport currently doesn't have 'flex fuel' so it would take some custom code (some meaning a TON) to get it working. And time of course

Oh wow that's cool!! Those cars are awesome

Tracking all and along the lines of what I was thinking. Lots of code and lots of tunes to allow for the dynamic nature of the fuel.

Thanks. It was a blast and likely the only car I have sold that I wish I still had!

As promised, I got the truck on the dyno and did some testing. (Note: 91 octane is the only 'premium' fuel in my area, so add +10whp to gains for expected 93oct results. That's typically what I see when tuning 91 vs 93oct, a +10-15hp increase.)

The COBB Stage 1 OTS 91oct map made 418whp 545wtq! (The Gen 2 COBB Stage 1 OTS 91oct map made 399whp as per my testing, so a nice bump over the older Gen 2 OTS maps! Great work, COBB!!)

My Custom Goosetuned Stage 1 91oct map made 444whp and 554wtq! That's +26whp over the COBB map, and +62whp over my best stock run (*382whp).

Then I was able to put the truck on E50! These trucks LOVE good fuel.

My Custom Goosetuned Stage 1 E50 map made 500whp and 581wtq!! That's +118whp over my best stock run (382whp).

These trucks are consistently stronger from the factory than the Gen 2. They make more boost and more power/torque from the factory. Tuned gains are about the same as Gen 2, which is what we expected.

Stock - *382whp 517wtq
COBB OTS S1 91 - 418whp 545wtq (+36hp over stock)
Goosetuned S1 91 - 444whp 554wtq (+62hp over stock)
Goosetuned S1 E50 - 500whp 581wtq (+118hp over stock)

I will be testing Stage 2 in the same way, over the next couple weeks. And I'll be providing the same data. If you guys have any other tests you'd like to see let me know!

*I could not find my 382whp baseline stock run file that I posted in the original post....I lost that run I guess. So I posted the 2nd run I did with the truck, stock. I will reference 382whp as the baseline even though the chart below shows 376whp*

Any Stage 2 updates?

Oh man, taking me back... I had one too, but not nearly as modified. Loved the z32, sweet ride man!

There is a bump in compression to 10.5:1 for the Gen3 3.5HO vs. 10:1 for the Gen2 3.5HO. Modeled compressor efficiency is also decently different on Gen3 vs. Gen2 - improved efficiency at higher pressure ratios and airmass vs. Gen2. Not a massive difference on the dyno, but I'd venture based on the changes in modeled behavior that there have been revisions to the turbos. High pressure fuel system now operates some ~600PSI higher than Gen2, DI injector flow rates at a given pressure are lower on Gen3 than Gen2, but that difference is offset by the higher pressure - total DI fueling capacity on Gen3 is slightly higher than Gen2. Port injectors on Gen3 seem to be a decent amount smaller than Gen2. Decreasing injector size is usually done to improve low-pulsewidth fueling accuracy, likely a key component of the change of Gen2 Raptor's emissions rating of Cali LEV-III ULEV125 ('17/'18) or Cali LEV-III ULEV70 ('19/'20) to the Gen3's Cali LEV-III ULEV50 rating. Hadn't done any testing with ethanol on our development truck, so I was curious whether E50 or E30 would be the point of diminishing returns. Great to see Goosetuned breaking the 500WHP barrier already!

With the higher operating pressure (~600PSI) of the Gen3 fuel system over the Gen2, will a high pressure fuel pump be required for E85?

taking my new gen3 to goose when it lands!

Any Stage 2 updates?

Actually yes.

I’ve been waiting to put out the video but I need to find my memory card! Smh

It made 15-18whp on both 91oct and e50 over stage 1.

Results were much more consistent though pull after pull

@GooseTuned looks like Cobb is saying auto start/stop is off by default in the access port and not user changeable. Any idea if you can re-activate it on your end?
