Here are the results from today's dyno.

Mods:
V3.2 (stage1/97% user torque)
catless DPs
DCI
FMIC


Condition:
~50 degrees
60% precipitation
93% humidity

There are a few dips in power and torque as the speed picked up, I think it might be due to faulty spark plugs. But I could be wrong. I'm changing them tomorrow and going back for another dyno soon.

Aside from that, I was a little disappointed with the gains, even with race fuel. Maybe I didn't tune it right, maybe someone with more experience can chime in and tell me what I'm doing wrong.

I was expecting to get around 375 hp~ on 92 pump gas, and very close if not over 400 hp~ on race fuel.........

I'm waiting for those dyno runs to get emailed to me from ETS, we did about 15 or so pulls but more about that later when I get the files......

Anyway, the following are the 3 best runs on MS109......

Correction:STD
Smoothness:5

I've read MS103 is more "stable" than MS109, and the octane rating in actuality is only 2 points lower than MS109.

I would also give the car a day or two to adjust to the race gas

380hp is nothing to sneeze at! Get it fixed up and raise the boost and you can hit 400hp. The MPH looks strange, did they not go to the redline or was this in 3rd gear?

Something doesn't look right towards the end of your rpm range. Don't know if you are 6MT or 6AT, but were you hitting the kickdown towards the end of your run putting you down a gear?

Maybe Shiv can chime in and give you a more detail assessment of what went wrong.

I wonder where I can find MS103, I got the fuel at a Baxter's near the PIR.....Didn't see any MS103s but there was MS101.

Thanks for the info!!

I know what you guys are talking about......I think I need to change the spark plugs. Because I was getting a few hiccups through out the dyno session, as illustrated by the graph. It always happens around 100mph or up when it happens......

Could that not be the spark plugs? Please chime in

TIA

Maybe if you are misfiring. If you have a BT tool you can tell that pretty quickly. Shouldn't you also be on Stage2 with your mods as well?

shouldnt you be on the stage 3 map?

The last run was on stage2, and the first two were stage1,I just took the best three and over-lay them.....I don't have catless exhaust. So I stay around stage 1 or 2....

No exhaust (OEM still)............

nice numbers man. those dips worry me though i know the mid one is vanos related right?

Thanks, I heard that automatics lose more power through the tranny than manuals?

I regret not having a fourth run with stage 2, because I now think that the results will be closer to 400 hp. I just didn't give it a adaptation run first like the first two runs, which are stage 1........Based on that, I think the second or even third might have yielded better results.

My first guess is that it looks like the dyno operator tapped on to a flakey tach signal. That would cause the drop outs in rpm signal which will effect hp/tq readings. So don't bother changing the plugs unless you are feeling the engine actually misfire on the road. It will be very obvious if it is. If you don't feel this, tell the operator to try another RPM pick-up source and the drop outs should go away.

And good choice using a stg 1 map on your set-up. With the factory cat-back still in place, stg 2 and stg 3 will too aggressive. You'd be amazed how much power the car will pick-up once you remove that final bit of exhaust restriction It really kills power. Especially when you have upgraded everything upstream of it.

6AT

From my experience with V2 on 93 octane running 100% torque values i believe 1 of 3 things. when i did the above 1/4 mile runs in this configuration, the car would go through 1,2,and 3 with no problems. When it did get to 4th gear and ~100mph it would hiccup/missfire.

possible issues
1. torque values are to high.
2. car is not fully adapted to the 109
3. both

in any case if i could graphically display what i felt in 4th gear on the track it would look like your dyno. after i started to lower the torque values my times and mph showed great improvement and no longer hiccuped.

Hope this helps

Did you use the same user torque settings on Stage 2 maps as you did on Stage 1 (ie 97%)?

Yes, all values stayed the same. The only difference is the stage.

I have the TQ value set at 97% on MS109, is that too high for that race fuel you think?

Also, I think gas adaptation isn't a factor because I've ran it from the get go. The three results that I posted here are one of the last ones we did. Prior, we did about 8-10 pulls on stage 1 but with the TQ value at default (~90%).

The reason why I say it might be because of the spark plugs is because I've encountered this while driving above 100 mph on the road. But only once in a while, randomly.

[psu139]

i would try dropping the tq values and see what results that brings.
