Well after almost 2 years, 23000miles, and a few mods I am finally getting my car on a dyno and tuned from its pig rich state...The funds have been hard to come across and finding someone to do a good job tuning even harder...

I currently have the Vishnu Stage 1+ kit on my car which has been on there for about a year and a half (yeah long time that my car has been hating me...) Vishnu Stage 1+ Specs

I have heard nothing but good things about the guys at Tuning Technologies (in Colton, CA (SoCal)) and decided today that now is a good time to get this done (Granted it is a bit hot, but that’s what the SMART upgrade is for).

For those that don’t know what SMART is, the following is a write up from the Vishnu guys themselves...
"Stands for Self Monitoring Active Real-time Tuning. This upgrade package converts your XEDE into a fully adaptive engine control system. One that is capable of making real-time adjustments to Fuel, Ignition Timing and Boost in response to changes in driving conditions. Expect substantial gains in drivability, partial throttle and consistency."

Wish me luck, I head towards Tuning Technologies August 9th for the session which is set for 2pm...and for those interested in the results i will be posting up Dyno charts as soon as I can...Hoping for 320 AWHP...

 

Congrats .... man im going to pick up a evo 9 MR later this month and taking it straight to Vishnu so i know you happy............ question with the tuning you have right know whats your AWHP

 

I really dont know...I have all the MODs installed just not tuned...only running off a baseline map...I will have them print off a dyno chart with a baseline HP number...

 

First of all I want to thank Alfred and his crew at Tuning Technologies for making this dyno tune possible ...I am extremely happy with the customer service and will continue to use them as my car gets more mods...

Here is the down and dirty on my Dyno Day...

Conditions on the Dyno: between 108 and 110 Degrees (Yeah, flipping hot), 4% Humidity

Blue lines are from the Vishnu Baseline Map and Red lines are the tuned results:


I am extremely happy with my results from today...with the temps in the 110's and a Cat restricting flow, 305 WHP is not bad at all...Also turns out that the car was running too lean then pig rich (That’s what I get for trusting a narrow band Auto meter A/F meter...lol...wideband is next)...

On the 91 Oct baseline map from Vishnu (Blue lines) the car peaked: 294 WHP @ 6800 RPM and 268 Ft. Lbs. @ 5200 RPM w/ A/F ratios ranging from 13.1 low end to 12.0 high end

On the 91 Oct tuned map from Tuning Technologies (Red lines) the car peaked: 305 WHP @ 6800 RPM and 279 Ft. Lbs. @ 5000 RPM w/ A/F ratios ranging from 12.0 low end to 11.1 high end

Gains within the power band are as follow:

Low End
27 WHP and 33 Ft. Lbs. @ 4200 RPMs / AFR went from 13.1 to 12.0

Mid Range
16 WHP and 17 Ft. Lbs. @ 5300 RPMs / AFR went from 12.8 to 11.7

High End
18 WHP and 15 Ft. Lbs. @ 6800 RPMs / AFR went from 12.0 to 11.1

All comments, remarks and questions are more than welcomed...

 

looks to me like you got your money's worth, more power along with a safer tune. Nice job Alfred.

 

I think your car should make more power than this. I made 295-300 hp on the same dyno with a TBE and drop-in filter. If you are using the stock cat, then that might be killing your power. I am running the HFC right now, but I got tuned with a test pipe.

As we have been saying in the "isn't it lean" thread, the AFR on the Vishnu base maps is too lean. Did Alfred increase the timing when he richened the AFR? Can you look at your timing map in the Xede and tell us?

Also, can you share your dyno run files with us if you have them?

 

Congrats on your results. Are you running HKS 264 intake/272 exhaust cams?

 

Well with the 110 Degree temps and my High Flow Cat...the power suffered a bit...I am just happy that my car is on the HAPPY side now...that bad boy was hurting and knocking like 15+ on that baseline run...

I will let you know about the Xede map tomorrow...

No i am actually running HKS 272 Intake and 264 exhaust...both at -3...

 

Are you going to try a 100 octane map? Your car will really wake up with the higher octane. I dynoed last year at Tuning Technologies in 98 degree weather with a water injection mix on 91 octane and that definitely helped with the high heat.

 

I was going to but the xede was maxed out on the boost with the pump gas...I need to get the passive boost emulator from the Vishnu guys to get my 100 Oct tune...

 

What was your boost maxing out at? The boost emulator will definitely help. I was having problems with low boost up at LACR in Palmdale with my Stage 1. I was only peaking at 20 PSI and tapering down to 16 PSI. When I added the boost emulator, I was able to peak at 22-23 PSI and taper to 16 PSI.

 

The hp numbers on your dyno sheet are corrected for the temp. If they were not corrected, then your real numbers would be 288 hp only. 288 whp is your real hp on that day with that high temp. That is why your numbers shot up to 305 when the 1.06 correction was applied. So the issue of temp is not relevant after the correction factor is applied.

That leaves the stock cat as your main hp reducer. It is a very restrictive unit. Get a HFC/test pipe and do a dyno run w/o tuning and your numbers should go up by 15-20 hp. Then you will be at 320-325 hp like a cammed Evo should be.

Glad that you got your car tuned and it is no longer knocking.

PS: Do you have the dyno run files? Can you share them with us?

 

Thanks for the tid bit on the correction...

And I do have a high flow cat on my car...AMS 3" TBE and thier HFC...

So Chevron 91 Oct and HFC are robbing me...what else can i do to help my car out before going turbo kit???

I also had someone on another forum tell me that the dips in my graph are a bit odd...what could cause that???

 

Dang...you made that much in an VIII? There was a IX on the dyno before me and he only had TBEw/test pipe and Drop-in just like you and left making 293 to the wheels in the same temps...Could something be wrong with my setup??? Is there anything I can check to see if something is wrong??

And by increase timing you mean more towards the (+) side??? Cause if that’s the case then no...More timing was pulled away in the map when the car was richened up...

 

Please post your before and after maps.
