Emira V6 Racechip now out

[Tracked Emira]

not concerned in the slightest. These signal faker piggybacks won't come close to all the benefits of actual ECU tuning.
The full tuning solution is a time sink but worth it in the end.

I'm ready to be sunk...just waiting for my ship to come in!

Torque is in newton-meters. That’s why it’s so high.

But yes. It appears they did the stupid thing most non-us based companies do and applied a correction factor to convert to crank power numbers.

I hate that crap. Report the rear wheel numbers. Every dyno is different anyways so they aren’t even really comparable.

Yes definitely Nm.
Their results seem to be well within expected for a stock car.

This was my totally stock car the only time I’ve put it on a dyno.
380rwhp and 442 Nm.

Never quite understood why the rpm seems so far out, though.

If that’s max power at 6167rpm then those numbers are suspect. They put in the wrong gear ratio or the whatever method they used for engine speed is wrong. Which will throw the numbers off.

dynos measure torque directly then use a formula to calculate horsepower. They don’t measure power directly.

@Terry are you saying the car makes more power using the JB4 with the OBD2 connection hooked up vs without?

Interested as that was NOT what was stated previously.

I only say that because in one of his posts in this thread he mentioned about power being made on map 3 with the OBD2 connector hooked up.

So the torque figure is correct, then?

Dynos' are funky things. Ultimately the only things a Dyno is capable of measuring is Torque at Wheel speed over a snapshot of time. Everything else is a calculation. Muck up one of the parameters and the calculated power, and even the torque can be out of whack. It's why you can't really compare dyno sheets from two different dynos. And even the same Dyno if the time between runs is too long as the operator could have changed a parameter.

I'll be honest 283kw, or 379whp in US for a stock V6 M6 Emira is higher than the average, most are 350-360whp and the Emira isn't known to be a particularly under-rated engine (BMW, GM LS, I'm talking about you!).

I've always said the BEST measurement of power is to hit the dragstrip and start comparing curb weight vs Trap speeds. Forget ET, you want the Trap Speed for power calculations.

Agreed.. as much as I want this to succeed and get the tune. Its all bla bla so far and no proof or whatsover. I offered many times my ecu for free! For the group and never got even back to me. I think its BS! Proof me wrong and stop acting like a child talking trash about the forum and the members.. without us you have nothing to stand on the emira! We provide you the info, the bits and pieces so that you can do your thing.. if we may believe that. So long… even if you come with something after today I will not buy from you, you are not worth to get paid for this the way you behave.

I can independently confirm that a buddy of mine has been working w @VF Tuner for over a month on this. It’s very likely the world’s first field-revisable emira g6 ecu tune. (Komotec won’t even sell tunes unless bundled with headers m, intake, and has only a static state of tune for that power kit. It must be done in Germany.)

Yesterday, the tuned ecu arrived at his house. I have seen photo proof.

He needs to get to dyno, but his car is at dealer for warranty repairs. Hopefully will be back in next week or two.

This car also has a custom mapped jb4, eventuri intake, catless GRP headers and a 2.8” pulley.

He plans to dyno jb4 vs vf tune head to head, once both teams have opportunity to further revise their respective tunes/maps based on dyno results.

Should be interesting

VF was probably guilty of underestimating how long this would take, and he had some unexpected serious family matters to attend to.

Let’s all try to take it down a notch here. (Holy shit @Porter why am I saying this kumbaya shit, get out of my head!!)

 

[Steve24]

That’s great.

The only slightly disappointing thing (and I’m not trying to be a downer or unnecessarily critical) is that this is being tested on an already highly modified car.

To be honest I’d rather see the results on an otherwise bog standard (or at least only very lightly modified) car.

Anyway, looking forward to the results.

 

[LotsOfTriumphsUsuallySexy]

Indeed, I’d want the minimal mods myself. No valve controller or 3rd cat delete. Maybe intake and pulley, in addition to ECU. Hopefully that should be enough.

 

[EZcheezy]

cool.
I've already posted *actual table pictures* of the Emiras ECU tables. Ours is just as real.

I don't know why I even bother with this community at all. 90% of what I get is just shit talk.

im rooting for you man i definitely want that tune you are working on.

if my friend wasn’t such a selfish asshole, he would revert to stock to dyno it in your preferred configuration, and then dial in both approaches w both tuners, for every single iteration of mods, until no one else would need to dyno for themselves.

Alas, he’s in it for himself I suspect.

I just hope we will get the dynos somehow…

 

[swannyu78]

I wonder if this would work on Evora 400 I’m uk based but it’s same engine as emira? Thoughts anyone know. I have pinged them in insta as well

 

[seriously]

Did this thread turn into a vf tuner thread too? Hilarious.

Haha! Fair enough.

I’m just interested in what would be relevant to the greatest number of people.

And from VF’s point of view, I would have thought a standard car (or close to it) would provide the highest number of potential customers.

Don’t blame me when people say the dyno results are irrelevant because the car was already highly modified…

 

[Tracked Emira]

What will be really be important is the difference in power between JB4 and VF tuners. But ultimately I would go with VF tuner unless there’s a major difference because I will do all these mods listed in the comparison. I just want between 500 and 550 horsepower because I don’t want to mess with the internals.

the crazy thing here is, a pulley and belt cost like $300 and take an hour or two to install (w small hands/arms). the pulley doesnt help w the stock ecu, since the extra air gets decline by ecu. however, with that problem solved, its super cheap power. more air is more air.

so anyone who does ecu flash should do smaller pulley. why wouldnt you?

all that leaves us with is intake and headers. many already have intake

so the objections boils down to headers... nothing to lose one's head over

I don't think it was Mat's call, necessarily. I dont think many other owners had the balls to step up and buy a spare ecu, ship it to europe, and basically FAFO w their emira. i know i didnt...

I think it was just my buddy and TFS who is also pretty modified IIRC

I think a lot of people will get the spare ECU after we see these comparison results.
I wish you guys well and I also believe a lot more will follow once their warranty expires.
If the car didn’t have so many update and other issues more would get the spare ECU sooner. Cooling will be an important key to sustain the power on track days
