My e63 tuned by wesitec, not happy at all, need help
Sup guys, I recently had my 2015 e63 s Amg tuned by weistec. I installed the tune/down pipes / stark plugs / air filter, everything from their site. I recently had the car dynoed at a local performance shop Fftec which uses mustang dyno. The result I got wasn't what I had in mind. On the wesitec site it states /724wtq with upgrades. I only got 542/736. The torque is there but I'm missing 100whp. Weistec stated when they did the dyno they had race gas of 103 or something and when I dyno i used octane 91. Then they blamed it on the mustang dyno saying it reads lower and then they said the drivetrain from the awd. But my track times wouldn't lie, which I included , just a .1-.2 faster time for 1/4 mile then a stock e63 s Amg
As you see on run 3 that's was the first tuned weistec put on my car which was below the promised, I contacted weistec and the person that installed it for me did few test and send back weistec whatever they needed. Weistec then stated my motor seem to be running a little hot and they said there was a new tune out and they installed it to my car. Went back to dyno and that's where run 1 and 2 542whp/736wtq in fifth gear, which they told me I must go in 5th gear. My only regret was I didn't dyno the car prior. I read a article somewhere where it states the stock e63 s Amg is 541whp/ 508wtq and the 1/4 miles is 11.6
I also went to the tracks and did a few runs, I was hitting 11.4-11.5 all day, track condition was fine 65 degree and I caught traction no problem and used launch control.
1. tracks result: stock(prior to mods) 91 octane: 11.6 -11.7 1/4 mile runs, stock tires
2. weistec tune, downpipes, air filter, stark plugs, pumped 100 octane, cut resonator / replace with x pipe: 11.4-11.5 1/4 mile runs, stock tires
3. weistec tune, downpipes, air filter, stark plugs,91 octane, cut x pipe/ replace with straight pipes:11.4 1/4 mile , stock tires
Is it me or did I just spend a good chunk of change for .1-.2 faster than the stock e63 s amg.
Let me know what you guys think and if you guys have similar experience and any advice would help . Thanks for hearing me vent
Run1 : 4th gear pull, weistec new tune<br/>Run2 ; 5th gear pull, weistec had sent me new tune<br/>Run3: old weistec tune
I sorry to hear about your disappointment. When I was going through the ECU and downpipes tune for my 2012 E63, I decided against going to Wesitec because the following vid:
http://youtu.be/SEyKEh_qdRg
It stated the AC stop working coming out of Wesitec so I dropped them and went to Renntech and then AMS ( loved the Renntech ECU tune, but went with the Alpha 9 package ). Hope you get it sorted out.
I was originally was going go with ams but someone talk me into weistec because they create safe power supposedly. How is the renntech/ams tune u got ? Dyno sheet or time slips?
I had the Renntech ECU tune with the 200 catted downpipes then jumped ship to AMS with their Alpha 9 with turbo upgrades and Renntech downpipes still in place. Very recently upgraded the Wesitec TCU. If I was comparing AMS vs Renntech ECU tune alone, I would say they are the same.
I have never been to a track so I don't have any track slips. I do get chanllenge allot around my neck of the woods and I can honestly say. Not a whole lot of super sport cars can touch me so I am happy with my result without have those numbers.
Good luck. I hope you find a solution to your tune. I'm sure Wesitec will make you a happy customer again.
What's your elevation? Density altitude?
The weistec numbers can be from a rwd e63 model. I plan on doing weistec plugs filters and 93 tune on my 16 e63s next month.
Have the plugs, filters and 93 tune on my parents GL 63. No issues. It's not tracked or dyno'd but she picked up on power. Driven hard too..... Hard to feel cuz it's 5800lbs but yea
I wonder if you have are having the same issues I had with my 2015 AMS tuned E63 at the beginning. My baseline dyno was about 500HP/550TQ and it only increased to 550HP/680TQ after the standard AMS tune. While the torque is within the advertised range, my wheel HP was about 100 short. Since I am local, my dealer contacted AMS and we sent the car to them for some dyno tuning. After the fine tuning, the car dynoed 597HP and 733TQ at the wheels. Although AMS doesn't believe the 2014 and 2015 model years to be different, my independent dealer who has contacts with someone higher up at MB states that there are small differences in the exhaust of the 2015, which is more restrictive that the 2014. So if the tuner's standard tune for the E63 is based on a 2014 model, then things might not work as great for the 2015 model year. I am a little confused in your case since you actually have downpipes, which should mitigate this difference. However, AMS has dynoed tuned multiple local 2014 and 2015 cars and they have seen significant differences in these hand-built engines, but 100HP difference seems a little much. I remember them claiming a normal 30-40HP range.
Those are disappointing results. My 2015 E63 S with the Renntech tune and mufflers and stock DPs and cats goes 11.1 at 127.56 in the quarter mile. And that was with a 1500 foot DA at Atco
rs4 tony: im not really sure what u mean by elevation or density? you mean conditions at the tracks? and yes weistec did stated the numbers were off a rwd e63. The thing thats bothering me is that i see all these other tuners ams/ renntech with basically same mods as me ( downpipe and tune) and there track times are like 11.1 as mention on the above post. not to say the ams tune/dp/exhaust hits 10.85 1/4 miles. im really just wondering why weistec isnt up to par. I really hope they do something about it, i been in contact with them and we are going back and forth with the email but i feel they just making excuses. I wouldnt be worrying on the dyno numbers if my track times were on point like the rest of the members here with there renntech or ams tunes. let me know how yours turn out tony if you still end up going with weistec , hopefully it be better then my experience
rs4 tony: im not sure what you mean by elevation or density, are u refering to track conditions? The things that bothering me is that i see all these other tuners renntech/ams that has the same mods (ecu tune,dp,plugs, filter) or less and for their 1/4 miles are 11.1 as the above post mention. I wouldn't be worrying on the dyno numbers if my car as actually near 11.1 or lower, but its not its at 11.4 and stock 1/4 miles runs 11.6. very disappointing. I really hope weistec fix this problem. and yes weistec did state the result on dyno is from 2012 rwd e63. But the track times wont lie, ran like 10+ times all consistence 11.4, hopefully you will have better luck then me if you decide to go with weistec. It seems there is so much better options out there.
Thanks everyone for sharing there story and experience and advices
When I went to the tracks I pump 100 octane and got 11.4-11.5, on a different day I use ran with the 91 octane and was hitting 11.4 all day . Elevation for dyno was sea level 50ft or 100ft I guess. Yes I understand mustang has a chance of running lower but my track times isn't where it's suppose to be at. Like some members on here with renntech or ams tune/mod running 11.1 as the above post stated

Reason: Adding more info
The HP difference between 91/93 octane and mustang/dynojet dynos should not be 100HP. I would suggest that you ask Weistec whether their E63 tune is base on a 2014 or 2015 car. I suspect that they did the development on a 2014 model and assumed that it is the same for 2015, which in my case was not the same. If they come back and say that it was a 2014 model, then ask if they have dynoed a local 2015 model with that tune file. As previously stated, I was down 100HP, while TQ was within the advertised range. AMS asked me to bring the car to them and they custom tuned my car on the dyne and I got the full 100HP back. I believe AMS now uses different tune files for 2014 and 2015 models, with the 2015 being based on what they learnt from my car.
Yes, Mustang dynos do tend to register lower than others, which is why they call it the "heartbreaker", but again given your TQ increase... something seems strange. It's almost like the tune is not taking, and you are just seeing an increase due to mechanical changes (DP, etc). I would be very careful about pushing that car until someone takes a look at it. If it is running too rich or too lean you could end up with a problem you don't want. GL

What do you mean by too rich / lean ? Fuel ratio ?
Please, educate me.

Please, educate me.
Air fuel ratio , less than x fuel called lean , can cause blown engine , crack in exhaust manifold , blown turbos etc . rich the opposite , more fuel than needed , less damage though . but I wouldn't worry , do you get check engine light on ? there is so many safety's in those modern engines , I hardly believe anybody can destroy the engine with just a tune .
What do you mean by too rich / lean ? Fuel ratio ?
Please, educate me.
Exactly: AFR, air/fuel ratio. Too rich = air/FUEL, too lean AIR/fuel.
Running lean can cause detonation, which is basically the heat/pressure in the cylinder causing combustion before the spark ignites the mixture at the precise time. It's also known as engine "knock" but in some cases it can damage engine components, especially in high output engines like these.
Running rich is generally not considered as big of a problem. However, my Evo threw a rod while on the dyno due to a rich AFR. Boom. Bye bye. New motor.
Considering that the HP number is way off from expected, I personally would stay out of boost until I had a reputable tuner find out what, if anything, is going on. Not just install a canned tune (even from Weistec) and let her rip. I would stand next to the tuner and make sure they were watching and reporting the AFR at low RPMs into boost.
The car will go to a limp mode as soon as detonation in place or knock or lean afr , EGT , knock sensors , primary O2s . I'm not saying to OP floor it every second , no , the it's not that big of a deal , also this ecu pretty smart , if I recall correct 25% adjustment .

That statement does not apply here. Why? Because dynos are a tuning tool, ie the delta (changes) in power is what is measured not so much the end result.
So if he only dynoed 500rwhp (which is NOT low by any stretch), then he should see a delta of 100-150rwhp increase with a tune, downpipe and filters.
That is not what he saw, his track trap speeds indicate he is making at best what the S (577HP) models run.
Another thing that is of note on his dynos...OP's RWHP kept getting lower and lower with each run by a significant amount. Even my stock 2012 with its less than optimal cooling kept getting higher and higher with each subsequent run.
I dynoed at 430-440rwhp on a 2012 E63 (with P30 package) bone stock on a Dyno Dynamics dyno (true heartbreaker dyno). I am not worried, car runs great and is very strong, in fact is stronger than my E55 that was modded to almost 500rwhp.
Now if after my RennTech tune, I get 480-500rwhp.....Yes I will be worried. But on the same dyno I am expecting 550-600rwhp with the Renntech tune and I will have gotten what I paid for.
91 octane, and plugs. Sometimes people have new plugs installed and they aren't properly spaced, this can cause you to lose power. The High TQ numbers though don't make sense, as other said have Weistec take a closer look at your car, after all the money you spent I would be upset too.

just go to dragtimes and click on his track (sonoma) for 10/21/15 and you get 924 DA... not to bad at all
