Interested! You can tune my ecu? How much? Also I would need to overnight it to you on a Monday, and can you overnight it right back the day you get it?

MTV10

Get a new tune and see if that helps. My 2 cents.

gaspam

here's my logs from some runs up to 120 mph today.... i have renntech tune... my logs show max boost topping out at 18 psi which is pretty much what renntech should be (18.8 psi) ... difference probably due to the fact that its a calculated value in the logging app.

as far as timing, im not seeing as much timing being pulled as you're logs are... I get about 3.5 to 8 degrees of advance at wot, high rpm ,high boost

At what time of day did you run, and ambient temp? Your IATs, as you had mentioned before, stay pretty low.

gaspam

ambient temp was 93.2 F and humidity was about 80%

Overnighted my ECU back for a re-tune. They stated they went more conservative for 10 degrees advance at WOT up top.
Got it back tonight, did two pulls with again next to no timing advance and car feels weaker than it did stock.
Did a 3rd pull/log and suddenly it bogged and got a bunch of misfire codes. Reset the codes and restarted the engine and gone.

Ill upload the logs....this is getting ridiculous. At this point im about to put my stock downpipes back on and have the dealer reflash it. What a joke.

Here are the logs. These are with 95 octane in the tank. Brand new plugs gapped to .024"

Have you gone over the install of your DP's? Tighten everything back down, check heat shield rattles, nothing is rubbing?

You have timing all over the place. Many times when timing issues and other installs, like dp's/exhaust, occur at the same time, it's a metal-on-metal issue that is being picked up by knock sensors. Not all the time, but it's something that should be checked.

I would flash back to stock and then do some logs. Seems like there may be a sensor issue somewhere.

Mike450

And that's good idea also because it can rule out the revised tune completely.

You're on the right path, fuel- re flash-etc, but unfortunately chasing knock is a pita process sometimes.

Why is the TPS only at 86.66% when the pedal is all the way to the floor?

Fairbird

correct , everything above 84% consider WOT

kponti

I read somewhere that one of the parameters used to control torque is through throttle plate settings. So you don't always get how much throttle you ask for if the ecu determines the level of torque that puts out is more than it's programmed for at that particular scenario

gaspam

TPS PID is a indication of actual blade angle, WOT TPS is generally 83 or 88% depending on calibration

gaspam

your IAT's are pretty high at the top end (81c = 177F) ... mine never go about ~140


when you are at full boost and at top speed of your run you are at 177F @ 106MPH ... i am at 118F @106 mph... I even carried my run up to 117mph and IAT stayed at 118F

TTMerc

My Stock 2014 cls63s ran 7.5X @ 95.5 on only 10lbs boost so it seems your numbers are low. The IATs also seem high like gaspam said. Mine did the same thing before. when the car is cool check the coolant reservoir on top of the motor make sure its pretty full also there may be an air pocket in the system. When you undo the cap you may get some pressure come out. Thats a good thing because the air will rise to the top of the system when cooled. see if that helps the Iats bc 177 degrees is pulling some timing for sure.

Just an update that ALL of the issues were rectified with a new tune from a different vendor.

I now have the aggressive tune from Eurocharged and the car runs great, highly recommend them!

chiromikey

I'm sure that was frustrating for you. Glad it got worked out. I'd ask who the original tuner was but I think I recall you not wanting to mention that in a previous post.

Amg63-

just recently got this same Eurocharged tune you mentioned and made 603awhp/730awtq with it. This is just tune only with afe pro dry s air filters, no other mods, no DPs and on 94 octane pump gas. With DP should be around 630/770 ballpark

great tune, car drives and feels great also highly recommended.

Chappy

Unless I'm reading it incorrectly, post #1 on this thread has your answer.

chiromikey

I see vendors mentioned but I still don't see a tuner mentioned. Post #3 was the one I remembered...

gaspam

i remember seeing it was originally speedriven... the op can confirm

iownedu

I am not commenting on the tuner for a reason, they gave me a full refund. I am out 2 overnight shipping charges on the deal though.

gaspam

its speedriven... I dont know why people try and hide tuners... what if this same thing happened to 100 different people but all 100 stayed quite? what if everyone stayed quite about MHP from back in the day?

not saying they did anything wrong, but no reason not to state who it was

Glad you got the issue worked out! Congrats on new POOWWAA! Will be awesome to see the results at the track in comparison.
