Wow!!

Do we get free re-tunes?

320 dreamer

if you purchase a eurocharged tune retunes are free. if you tune on a dyno then the dyno time is charged but tunes are free

Gramma_Benz

Actually, I believe mail in re-tunes are free, but dyno tuning costs. It's like $100 for custom dyno tuning and $100 typically for Dyno time.

Dyno tuning take a lot more time and effort. A re-flash takes 5 minutes.

Just wanted to give a little more feedback since I've driven the car more in a daily driven way. The new tune is incredible. The most noticable tune I've received from Jerry yet. Besides a bit more power, the TCU mod allows power all the way through the gear, while before it was more progressive. Upshifts and downshifts are lightening fast. It feels like a totally different car.

If you haven't done it, it's a MUST do!

gtr886

Did you fix the problem with your ECU?

Gramma_Benz

Ahh....what problem was that?

SYZYGY

can you clarify that this TCU mod is a different upgrade from EC's stage 2 ECU upgrade that's listed on their website? I don't see a TCU option listed on there.

Gramma_Benz

Any clarification regarding services is best verified by Eurocharged. Just call them, they're cool to talk to.

Got my Dyno Graph emailed to me from Robert @ Dito Motors:

how exactly does a tcu mod inc. hp and torque?

c32AMG-DTM

The Transmission Control Unit (TCU) isn't controlling any variables that affect power output - so it shouldn't have any affect on hp/tq, with the possible exception of any torque-limiting parameters in the TCU. Since a dyno run is a pull throughout a single gear (usually 3rd or 4th for our cars), i.e. there's no shifting, I can't imagine how you'd see TCU tuning show on a dyno graph - again, with the one caveat of TQ limit removal showing a possible increase in low-end rwtq.

Either way, the TCU is a separate controller, located under the passenger-side footwell. If you're getting a TCU tune for a C32, you need to have the programming altered within that separate controller. It can be bench-flashed, or I think a TCU tune can be pushed onto the TCU controller via OBDii.

Gramma Benz, the graph is a bit curious... it looks to be a normal, healthy curve that plateaus at ~350 rwhp, but then horsepower and torque both spike briefly towards the end of the dyno run before tapering off again (around 5600 til 5900 rpm or thereabouts). Did all of the runs show that same anomaly? I see the correction is "Standard" - did you also get the graph corrected "SAE"?

Gramma_Benz

Yeah, I think I may be mislabeling the mod. It's ALL part of Jerry's ECU tune and I think you're correct in stating that he's changing the torque limiting parameters, so you have more torque available throughout the RPM range.

Yes, I run slightly lean for about 500 RPM's. I'm running out of fuel. I need either larger injectors or need to get a bigger fuel pump to increase the fuel pressure just a tad.
I'm searching out possible solutions, but first I'm trying the easy, cheap obvious things, like fuel injector cleaners and checking my fuel filter.

gt4awd

The injectors are good for up to around 500hp. The fuel filter with internal regulator, and fuel pump are the limitations. I believe just the SL55 fuel filter with higher flowing regulator would do the job without an additional pump. Not sure on that one though...

I have the new jerry tune and was wondering if anyone else has it with a sprintbooster on a C32. I was wanting one before but this new tune makes the my throttle super
sensitive and I was wondering if it was even worth it.

Gramma_Benz

I do. If you're happy with it now, don't do it. It doesn't make u faster anyways. I had one already, so I've just gotten used to it. I do like it I must say, but it's totally not necessary.

JUAN CASAUS

Have you tried your car without it after the tune?

Gramma_Benz

I haven't. Jerry's tune def made the throttle tip in more responsive tho.

mjgroves

Just want to chime in here... I was the only SRT6 present at the last tuning session. Turns out, my car already had a damn tune on it! GRRR!

However, Jerry did reflash with his TCU mod. We went for a spin and I was skeptical, as it felt different and felt slower (he was stunned). I have been driving it more lately and it's definitely grown on me.
I still have the stock contis on the car and I suspect traction control was playing a large part of the slowness. Believe it or not, perhaps it felt slower because I was A) driving like ***** or B) TC was turning on more often than it did before at certain throttle points I was used to, thus giving the illusion it felt slower.

One thing I didn't know about is the rev limiter appeared to have been raised even further from 6200 RPM, which is what the previous tune had on there before. I noticed this the other day, watching the rpms approach almost 6500 RPM before shifting.

Seriously though, is this really a safe RPM to be hitting in these C32 AMG engines? It is sorta scary seeing the needle so far into the RED ZONE.

I used to have a problem hitting the rev limiter (car lurches, sounds awful, finally shifts, and away you go) but now I don't.

320 dreamer

finally some clarification!!! i was fortunate enough to get this new tune before most of the 3.2 engines. jerry fine tuned the files on the v8 then adapted it to the v6. when i went out and drove mine it was like a new car! the shifting was silky smooth and the torque curve was unbelievable. he has really outdone himself, i cant wait to get it on the track

JUAN CASAUS

Yeah...due to this tune I'm gonna need wider tires to get some traction in first and second gear. I'm running 245/35 18 michelin ps2's now...any recommendations on tire size/brands?

loungn14

I wouldn't trust this my friend. Just because A/F is ok, that doesn't mean that the injectors are. I had the highest HP C32, and ran out of injector north of 400whp. Your problem is your looking at static injectors or injectors running at full duty cycle. Not a good thing for prolonged use.

Do the pedal reset, and re-evaluate. I have yet to see someone not drastically notice the new stuff and we have done hundreds over the last few months.

We typically raise the rpm to 6500. I was the first to run that on my car and did so for over 40k. Never had an issue.

You sure it was the rev limiter you were hitting and not torque limiting? Very simular feels, but for different reasons.

JUAN CASAUS

Thanks for the tip. I reset the throttle and the power is still there but without the jerking.

mjgroves

I have a sprint booster, I was told I wouldn't have to reset my throttle ever again.

I only ever had a problem with the rev limiter in 1st gear, I guess I wouldnt know for sure which one I was hitting. All I know is I would floor it, it would hit redline, lurch, shift, then be ok.
