*Edit* - All Software issues are fixed, please read below first graphs.

One thing to keep an eye out for, the coupler that goes from the intercooler to the throttle body failed. There is a factory rubber insert that popped during the calibration process. We removed the intercooler, removed the rubber insert, and put it back together - No issues since.

*EDIT*

With an updated version of software that has the definitions properly defined, we were able to get past every limitation we were hitting in the prior software. Being able to raise the boost and torque limitations, we were able to pick up another ~30ft/lbs of torque, horsepower generally stayed the same as boost was not able to hold past ~4800pm. We were able to pick up approximately 15whp between 2800rpm to 4500rpm.


Final Stage 1 - 223whp 304ft/lbs



EFI Stage 1 vs. Stock

+63whp @ 4000rpm
+107ft/lbs @ 3200rpm

Pretty interesting! How was spool up compared to the older LGT's?

A pretty cool solution on FHI's behalf there. Going to be interesting to modify

Smart design, hard to modify. Manufacturers will have to start from scratch to come up with new ways of mounting large turbochargers and intercoolers. I do like the design, this will dramatically help spool, although the right angle that the exhaust has to make to exit the rear of the car is nasty, I'm sure there are solutions that will make this car very fun to drive.

Correct, Primary and secondary 02 Sensors are about 8 inches apart, and are accessible from the top of the engine bay.

Chris is a bad ass tuner.... we've noticed exactly the same issues here at surgeline.


Chris,
Please see your email for a new program with torque control tables and new boost cut definitions. I'll send you my base files as well

Regards
Tim

Thanks Tim,

I have the car until about 3pm EST, so another 1.5 hours.. If you can get that to me before then, it would be fantastic. I have also posted my findings in the Cobb ProTuner section on the Cobb Forums.

Thanks,
Chris

This is sweet, definitely my next project, wish I could afford it now. Great work guys! Any more pics of the manifold and turbo would be great.

You might try seeing if anyone has all the definitions defined for romraider or ecuflash....

http://www.romraider.com/forum/forum8.html

Some of the boost limit tables are in Absolute Pressure in romraider.....maybe try upping the limits to target+14.7

The header piping, intake piping to the intercooler and the exhaust piping look pretty big.....maybe its just the pics. What size is the stock exhaust?

The last revision from Cobb had all the definitions I should need to finish this car today, the largest issue was overcoming the torque limitations that were not defined in the original version I had.

The primaries are large, after the cat seems to be about 65mm, maybe bigger, where the exhaust really closes up is at the "Y" intersection, then it looks to be about 35-38mm.

Thanks,

Chris

Your reading the graph wrong. Top bold red line is torque, lower thin red line is boost.

We have reached a finishing point with the Stage 1 tuning on this car. Thanks to Cobb Tuning and Tim Bailey @ Surgeline for getting us an updated software package that has the definitions needed to surpass the torque and boost limitations we were having.

Final Stage 1 - 223whp 304ft/lbs



EFI Stage 1 vs. Stock

+63whp @ 4000rpm
+107ft/lbs @ 3200rpm




Thanks,

Chris

How does this compare to the last gen LGT, both stock and Stage 1 tuned?

I've been very curious about the new turbo/manifold design, good to see some results. Thanks!

I was subtracting 14.7 (or so) thought maybe it was absolute pressure.


Ooops.

Seems like a front mount for this car would have pretty short piping.

Also, looks like only a 15 minutes downpipe swap. (assuming you have one)

Cool stuff, I wonder how big a snail you can fit in there

Just noticed the serpentine belt, interesting.

Undetermined at this time. We have not removed the turbo from the car.

Below are a few graphs comparing it to a 2008 Spec.B. This map was just an OTS Stage 1 map, so there was no custom mapping involved at all.

Cool. I'm sure getting around these limitations will only get harder in the future, but Cobb is on top of it. That looks like a lot more fun than stock.
