A terrible day for any kind of driving, but an awesome day for dyno tuning. All it did was rain very hard or snow alot . But that did not stop us from visiting the real nice fellas at AMS and get Bezimo's (my brother) Evo 9 tuned.
First baseline netted only 262 hp with his mods and about the same tq. Second baseline run jumped to 292 hp and 260 tq. Martin from AMS seemed to be scratching his head alittle bit tring to figure out why the 30 hp jump with no tuning. The third and fourth baseline runs were more consistant with 289 hp and 258 tq. So we will use those runs as a baseline average.

Then the fun started with tuning and average runs netted in the area of 300hp and 300 tq. With two final runs being the same capping the day off with 315 hp and 299 tq. The plots show an exellent tq curve. I will have them posted hopefully later this evening.

Bezimo's mod list:
RSR Exmag exhaust
Turbo XS downpipe
Highflow 3'' cat
Logic i/c piping upper and lower (painted gloss black)
Weapon R engine dampener
Autometer boost gauge
Greddy type s boost controller
Greddy auto turbo timer
K&N drop in filter
APS BOV
AMS dyno tune

I must say that AMS as a whole and Martin are pure professionals. They did not complain about Bezimo not using their parts or anything like that. Last time Bezimo and I had dyno tuning done at another performance shop, we felt that the shop owner (who was also tuning the car) complained about the parts we choose and had all sort of excuses about the car not making power after the tune. I did not hear any swearing or cussing. The shop was clean and amazing. Multiple 4G63 engines sitting on stands all looked like they were awaiting to give cars a big injection of power. And they actualy make their own parts. I just thought that they had them ordered to be made elsewhere. And they all seemed to be busy, which I like with no one just standing around doing nothing. AMS is just like a pure performance factory. To bad other shops can't say that for themselves.

 

We need to hear some driving down there stories though from the WI folks!

I'm heading down there tomorrow, hopefull the roads'll be a bit nicer....

 

The roads on the way to AMS was not that bad in the morning, but on the way back it got hairy.

 

after I hit about janesville going to ams it started to rain...later on in the day it started to pour and hail so hard. coming back from ams the roads were real slippery.

 

can't wait till I get my ride flashed also....hopefully within a few weeks....

 

AMS does a great job with these cars! Anyone who can make to them to have Martin tune it will not go away unhappy! Great bunch of guys!

 

AAAH! I have the plots but I can't get them on a post. Can anyone help?

 

bezimo's dyno #'s..if they're too small ill resize them just tell me

btw nice #'s .

 

I just e-mailed them to you. Thanks!

 

If you look at the first plot, you can see one of the runs A/F is just out of wack at higher rpm. Probably one of the reasons we were getting inconsitant power on the baseline runs.

 

what did they tune it with

 

That first pull had the stock ECU pulling some timing.
When I tune a car a will run it and fine tune it untill it gets consistant horspower and torque. It would be very easy to just throw timing at it and crank up the boost. Then start doing runs and eventually you will get one where the ecu doesn't pull timing and gives you that big HP #. That big hp # is worthless if you can't repeat it on the street.

Would you rather have a car that would make 322whp, 312whp, 340whp, 315whp on runs, or 330, 332, 329, 333whp? Even though the first car made more power, the second car would consistantly walk away from it in a race.

Tuning is more than just making a peak number, it's about making consistant power to the application. There is a different safety factor for a street car, a drag car, and road race car.

I also use SAE correction factors because that gives me a good baseline to compare cars, no matter what the temperature is outside or the humidity. You really can't compare two cars if you run one in the dead of winter with the doors open (50 degrees and low humidity) and another car in the summer on a 95 degree day with 80% humidity.
I'm not trying to bash other vendors or peoples dyno curves, I'm just explaining why I use SAE even though it might not give the highest power levels.

 

Good numbers, a lot of tuners don't use SAE conversions and the numbers are higher, so these numbers are very impressive. I think with a test pipe he could pick up another 10WHP.

 

The car feels great and the tune was worth the money definately. The peak HP number doesn't bother me since their are other factors involved with that and what others say they achieved on other Evo IX's. A quality tune will get you the a great increase in torque and HP at around 3500rpm. Those dyno racers that try to get a big HP numbers with inconsistant and uncorrected numbers are really not telling the whole story. Overall the car feels like a beast and can't wait for spring.

 

We are thrilled you are happy with the car. Hope to see you in the future.
