Wrapped up a 05 Stg 1+ EVO today.

Brown run was from a few months back. It was custom tuned with an XFlash (270whp) on 91 oct.

Purple run was from today. A test-pipe was installed. As was an XEDE. The XFlash was changed to an XEDEFlash. It made 286whp on 91oct

Red run was as above but tuned on 100oct. Boost was kept conservative. Car had a stock BOV It made 320whp.

Thanks Shiv, the car runs great dont think ill want to take it off the race gas map. Am I going need to do anything to my tune when I put in the new blow off valve?

 

Hi Joe-- glad you like it. Stg 1+s on race gas are a blast. When you install your new BOV, just monitor boost. Make sure it doesn't go up too much on either the race gas or pump gas map. At most, peak boost should only go up 1psi. If it goes up more than that, the boost table will have to be adjusted downwards a few points.

[QUOTE=shiv@vishnu]Hi Joe-- glad you like it. Stg 1+s on race gas are a blast.


I agree but Stage 3s on race gas are better than Sex! Well not really, just cheaper. Hookers cost more than race gas.

 

Hi Shiv,

I was wondering if you have a Stage 0 100 Octane base map that can be posted on http://www.vishnutuning.com/xede_support_evo.htm ?

Also I was wondering if there are Stage 1 base maps available for 272 cams... with the gears set at zero ?


Edit: BTW this is a 2005 , V3.2, Smart disabled.

I see VP 109 in your future. Get u 330+whp and go run 11s at Sac Raceway.

 

solid power.

 

Those are some very nice gains on race gas. I wish you would post the maps you used so we can see the difference between the race map and the pump map.

Supposedly we can build our own race gas maps by Pulling 4% fuel, zero'ing timing, and maxing out boost. When I run race gas its 104 unleaded and that seems to provide a nice bump in performance with no timing retard. The only problem I run into is maf cut. I need the XedeFlash.

However, it would be great to see what an actual tuned race gas map looks like. I took a look at the 05 100 octane maps and they still have some timing being pulled. But since I run 104 I'm not too concerned.

Nice job on the DYNO....I was shocked the Testpipe didn't provide bigger returns but since the tune changed as well its hard to say.

 

Don't overtighten your BOV. If you hear a chittering sound when it vents, then you are getting compressor surge, and you need to loosen it up.

Shiv, or Joe: what cams was the car running? Also, prior to the test pipe going on, what cat were you running (stock, or high flow)? The car looks like it would be a blast to drive.

Shiv quick question
why is the peak tq in your tune always seems much lower than the Hp ??

 

Shive, I have a question. Can you post a graph of an X-Flash stock Evo 9 vs. an X-Flash stock Evo 8 on 91? THanks.

 

Ludikraut- I am runnig 272/272 and prior to test pipe I was runnig a Works Hi-flow cat. And yes the car is so much fun to drive. Im still running on the race gas, had to stop buy our local 100 octane pump and put some more in.

 

Because I only add in 2-3 degrees of timing at WOT with race gas. In the 4000-4700rpm range, one could add in as much as 5-6 degrees if he felt so inclined. And since there is only 2-4 degrees of advance in the first place, the extra 5-6 degs will make a huge difference. And it would add another 20-30lb-ft of torque. But in road racing applications, that midrange would get a little unstable if subject to constant heat loading. Same reason why I rarely run more than 25psi on the stock turbo when it could run as much as 30psi (in the midrange) if one were to really crank things up. Basically it's a trade off between performance and longevity/safety margin. I tend to drive cars hard. Not as hard as chronohunter, but still pretty hard. Heck, all of us here at Vishnu track their cars religiously. So we like to be a little bit extra safe at times. No fun worrying about your engine when you're trying to make a clean pass

I'll have to it dig up when i get to the dyno shop. I'll try to remember... i promise

PS... look what Calvin just found:

Looks like one of our customers made a little video of us dyno tuning a Stock EVO 8 with an XFlash. You can compare that graph to the IX graphs I posted up earlier. So who made this video??? PM me

 

And that's why you guys got my business.
