Dyno results not what I was expecting

I wanted to get some peoples take on something. I just got my car dyno'd and the results weren't really in line with what I was expecting.

have the Eurocharged Tune: http://www.eurocharged.com/products/...se-model-451hp

With my car having the P30 package I was supposed to be sitting at about 540 HP. I hit two runs right at 389 WHP. The operator didn't think that made sense at all.

The below company did stock dyno's on the P31 and the non-P31. My car was sitting right at the stock numbers for the P31 package. But that conflicts from the datacard that I have for my car which clearly states P30 AMG performance package.

http://oetuning.com/blog/tag/c63-amg-dyno/
  • P31 C63 AMG Baseline – 390.8wHp & 352.6wtq (blue) 394.3wHp & 347.3wtq (pink)
Is there some way that the tune didn't take?

What kind of dyno? What was the temps. Dynos are tools used to see gains from mods on your vehicle. Not to be compared with other dynos. Doesn’t work like that. Every dyno is different. Where are you located?

Dyno Jet
probably 87 degrees

I know all those things factor in but I was expecting something in the 420-430 range.

Even the the operator said something seemed off.

If you search there are some threads about others having issues with getting a eurocharged tune to work, I forget if it was V6 or V7 but there were a few people that were seeing stock like power after flashing, think it was with V6 and it is a long thread about it and a lot of back and forth with Eurocharged adjusting things.

540 quoted is crank which is about 450 whp, but that is on a dynojet, let us know what Dyno you used, if it was a Mustang (known as the heartbreaker dyno) you could be seeing under 400 with a tune.

unless you dynoed before and after on the same dyno with the same car pre and post mods...comparing other dynos is pointless. i've also seen dynojets from 2 different shops 6 miles away from each other show completely different results for the same car.

some dyno's are considered "heartbreakers" some are not regardless of brand...but mustang and superflow dynos always read lower than the rest.

also i'm assuming you put your car in dyno mode within the cluster menu?

Yea I was able to put it in Dyno mode before throwing it on the dynojet.

I just though this was such a discrepancy in expectations of WHP. 30-50 WHP is way off.

Like hachiroku said, only way to be sure is remove the tune, go to the dyno, get a baseline, put the tune on and drive it around a bit and then put it on the same dyno the same day with the same operator (and hopefully same temp and humidity) and then you will know how much you gained - dyno could just be setup different, different correction factor, poor operator, a lot of variables, really only matters how much your car changed on that same dyno.

oh ya...also...supposedly with the Eurocharged tune you have to drive it around for a few weeks before you dyno it. They always read low until your ECU makes adjustments.

Not sure about that.

Did a few dyno pulls right after tuning the car and it made 464whp/421wtq..

Have had the tune for about a year. Just never got it dyno’d. Got the tune right after a purchase so had nothing to compare it to really.

A 60+ Whp discrepancy between our cars can’t be because of which dyno we used. That’s way too big of a gap.

No, it isn't.

Identical cars. One on a mustang in Denver and another on a Dynojet in NYC and I wouldn't be surprised at 100whp difference.

As mentioned above, dynos are best used to measure gains/losses. The track (60', ET, Trap considering DA) is where you'll really find out what is going on.

Sounds like your car is just fine to me. No CELs, running smooth, etc.

flash it back to stock do a dyno pull and then flash tune in and see if there is a gain

I'd be curious to see what the car makes on stock tune too. The problem is the variables still won't be the same if you don't try the same day on the same tank of fuel, etc, but at least try and do it in similar temperature.

I don't really agree with some of the above statements though, sure you can't expect your numbers to be exact same as a different car on a different dyno but these cars still to seem to dyno around 400whp with the performance package stock and what, like 440ish whp with a tune? It would be different if you were within 10whp or something , then I'd agree with some of the above statements. And it's not like you were on a mustang dyno either, which tend to read on the lower side. Those hp numbers are what I'd expect from a stock car. This is just based on results everyone seems to get on average, give or take a few hp, on this forum.

Your car should be at around 400-420whp at best. 389 is like 10whp less and probably due to the heat soak on the day. 440whp stock is like....unicorn EC Canada numbers or that other place that has popped up lately with unicorn cars.

It's the middle of summer...none of our cars are going to perform that well on a dyno. Hell, mine dyno'd 500 on a cool day in the Spring, but I am sure it'll be a lot less than that if I dyno now with IATs well over 100 degree's F. On cold mornings or at night though....MMMmm...yummy.

In other words...your car is fine. Go hunt down some (stock) Audi's.

If you are tuned and only got 389 whp with a P30 car, then the tune is either running rich or it's running too much timing causing detonation/knock. Stock, P30 cars should dyno around 400whp, which mine did. When I loaded the Eurocharged V5 bench tune and went to the drag strip, my times were slower than stock with no gain in mph (good indication of power increase). I knew something was up so I dynoed the bench tune and got stock numbers. Jerry had to adjust the bench tune a couple of times on the dyno to get the numbers in my sig. Like mr747 said, flash it back to stock and get your baseline dyno first. Then load the tune and see if you get any gains.

I literally just loaded the EC tune a couple days ago.. It was actually terrible... sluggish, terrible shift points, bogging down, really reduced mileage, you name it. Tried battery disconnect for 8 hrs at Jerrys suggestion. Didn't work. Went back to stock. He sent a revised file yesterday which I loaded last night.
Completely different and while i can only go on my butt dyno, its a huge difference now. I am curious as to what was different between file 1 and file 2.. I also am going to wait some time while the ecu does re-map over some time for a final analysis.

I'm pretty sure he's saying his car has an EC tune though. He's putting down stock numbers. Do these cars not generally dyno 430-440whp tune only, and like 390-400ish whp stock with performance package? Unless I read it wrong, then I retract my previous comment too.

shane your exactly right. I’ve got the tune on a p30 so was expecting around 430 whp. I’m going to talk to one of my guys tomorrow to see if I can get the software since I originally had the ecu sent to eurocharged for the initial install.
