Hypertech Max Energy Sport CAI Update Now Available!

[Chris@Hypertech]

Hi Chris,

Been datalogging all different settings:

about 18 psi with Hypertech and about 18 psi without Hypertech...

That's why my car isn't any faster...

But it runs fine and its a lot more sensitive on the accelerator. Revs nice to... but not going any faster...

MSMS3 was exactly right...

But there are a lot of reasons that a car can operate at the same boost level as stock and get better acceleration with an aftermarket tune. It's not all about boost. It's about the load maps, AFR adjustments, changes to injector pulse parameters, changes in timing advance and many other variables that enter into the tuning process.

Just because your boost pressure is the same, doesn't mean that the car isn't making more power. It is possible for you to be seeing the same boost pressure with the stock tune vs. the Hypertech tuning. The aftermarket intake is probably causing an error in the ECU calculations for the amount of air entering the engine, resulting in excessive boost, leaner AFRs, higher EGTs, and aggressive spark timing. The addition of the higher flowing exhaust, with the stock tune, just compounds the problem. What we saw on our car is that the Hypertech tuning, with the correct MAF readings, allowed the engine to make more power, at the same or even lower boost levels, and reduced the AFRs and EGTs. The attached graph shows more info.



Power is not made with boost. The turbo can only flow so much air. The higher the boost, the hotter the air. The trick is finding the optimal boost to keep the airflow efficient. This cant be done at one boost level. The boost level must be tuned differently as the engine RPM increases and the physical 2.3L of displacement pumps faster and faster and demands more and more airflow.

Yes, when you select the option to remove the 0-60 throttle restriction, the programmer raises the boost cut in 1st and 2nd gear. We also raise the overall boost and load cut limiters, but we don't remove them.

Hi Chris,
On the MS3 there is an optical encoder on the steering shaft that is used to cut boost when the wheels are turned beyond certain angles. What I'm asking is if your programmer defeats that.

It's not defeated by the traction control switch, so it works all the time.

Thanks!

I think the sensors you're referring to are part of the Dynamic Stability Control System (DSC). The programmer does not defeat these sensors, or any other function of the DSC or TSC.

Good question, but possible explanation would be that you should also be running close to 18 psi without the flash. Opening up the exhaust raises stock boost levels. Peak64 seems to just have a race pipe. I don't know what other differences the Eurospec model has on either tuning or on the exhaust side. Maybe different mapping in their ECU? Maybe different stock downpipe? Dunno. I think their CBE is different, so changes on the exhaust side ahead of it may produce different changes in flow and boost capabilities.

But all of us running US spec cars with catless dp/rp are or should be seeing 17 or 18 psi on stock tune. My car does. And I know that some guys on stock tune with just a race pipe are getting hard load cut, suggesting that they are getting above 17.5 psi under certain circumstances.

But there are a lot of reasons that a car can operate at the same boost level as stock and get better acceleration with an aftermarket tune. It's not all about boost. It's about the load maps, AFR adjustments, changes to injector pulse parameters, changes in timing advance and many other variables that enter into the tuning process.

Good info, I have read a lot about seeing higher boost with DP's and RC pipes. But I only saw 15 PSI with a catless do with only a small spike in 3rd sometimes. Now I see 20 PSI and settling at 18 or so( All gears). I was just a little weird to see him at 18 PSI stock and 18 on the tune. With his mods with the tune he should see 20 PSI like me and settling at 18ISH.(uhm)

 

[Chris@Hypertech]

It could be the difference in the exhaust. Not sure if he has stock DP or aftermarket. Corksport also makes the racepipe with and without catalyst. Not sure about catback exhaust either. The difference in the restriction could affect boost levels.

There are other variables that will affect boost levels, like altitude and fuel quality.

 

[anm6]

Hmm definitly weird? I would try the dyno before and after runs like Chris said boost is effected by a lot of things but you could actually make more power at the same boost level with a lean map and timing adjustments? 18PSI on stock exhaust with race pipe? I have a catless DP and only saw 15 PSI stock, I guess thats just how different each car is. As far as the intake goes have you tired switching to the Nano on the tuner. I was using the Corksport first( Went back to 15 PSI) Chris told me to switch to the Nano and now the car runs A+++. It only takes 10 mins to uninstall and reinstall it with the different intake and it would not hurt to try it and see what happens.

Did you look at the diagrams above. A standard MPS3 delivers around 280 engine hp with cbe...My car is already BMW M3 fast, but my question is if the power Hypertech promise is noticeable? I can't make my car go any faster with the tune... hrm yes I got 3 miles higher top speed than stock and 0.2 seconds better time at 1/4 mile... but that could be driver related... 50-75 on third... no improvement at all. The Sri cut a full second from stock, so I don't buy that about messed up MAF readings and all. If that would be the case, the car wouldn't react so good changing intake... It should behave as with the stock filter. The racepipe did almost nothing when it comes to performance. When I signed up for beta testing I thought that Hypertech would make my car considerable faster, but no. But I still really like the way it drives...

(1.3 -1.5 Bar... 18.7psi to almost 22 psi with a safe tune is what we get in Sweden. Why should you stay at 18?)

Lol your funny

 

[MSMS3]

Lol your funny

+1000. I don't see sustained boost above 18 as being safe on this little K04 turbo, at least not safe for very long. Yeah, you can run a hot tune and make a little more power, but you can't get much beyond excessive exhaust gas temps and turbo failure if you push it that high for very long on this little turbo, IMHO.

Simple intake does produce very significant gains, though, on this engine with very safe AFR's if you have an air straightener and do not introduce turbulence to the airflow across the mass air flow sensor, and Peak64 is also dead on right that test pipe frequently does not show much in the way of gains (but it should be good for 5 hp or so).

I'm not taking a position on Hypertech's tune on the European version of our car, as I simply do not know. I am saying that a good tune can build a little more power at safe boost and AFR levels, and a bad tune with excessive boost levels and careless attention to load mapping and AFR's will destroy this engine, probably right after it lasted long enough to produce a spectacular dyno printout or after it gets you through one relatively short road race!

all this speculating is really killing this thread. dyno it before and after, post the results then argue and nitpick away. im sure enough people have these flashes now.

No, defeating DSC thru the "hold during key start " routine does nothing for the cut during wheel turn.


check with engineering, please

Hello, Chris!

Any info on flashing european ECUs? I fairly tried to inspect all the thread pages, but didn't find any answer...

Here in Russia we have only the magic guys with notebooks, who sit on a passenger place and you drive with them the whole day, and they do map corrections on the fly. But it is very pricy - about 600$ each tune, so I still aware of doing that...

 

[Peak64]

It works fine on my swedish MPS3! (2thumbs)

Peak64:
Og hvordan arbeider denne enheten? Fordi jeg vet ikke noen stykker hva arbeider bra med bilene vres.

Sorry, I'm going to norwegian courses now so a little bit of scandinavian practice for russian guy on american forum is quite ncie

Whoah, what has happened to all Peak64's posts?? Looks like people here replyes on nonexistent posts

We didn't disable the DSC when we were testing with our car. I'll have to look into this and get back with you.

Jakis,

We have a few beta testers out right now with our tuning in European cars. Peak64 is one of them. We will release for sale when all have reported back successful.

Thanks,

Chris

I deleted my post due to a lot of speculation from my side...

Nu ett svar till vr Norske vn: Ls mer p den svenska mazdaspeed.se sidan...

Sorry for the Swedish... it wont happen again. (no) I rederected him to our swedish forum instead.

Cheers

Well that's nice to hear! Can also become a beta-tester for russian-market MazdaSpeeds (though I believe they must be the same as Europe ones)

Update

Well, Friday will make it one month of having the Hypertech on the car. I really like it. I did change the CAI selection in the tune from Corksport to CP-E Nano for my Cobb SRI based upon Chris's recommendation. Car feels tough as hell.

On my first couple of tanks, my mileage was up about 10%. This was after adding the test pipe, TIP and Hypertech. In my most recent tank it was about the same as before, but I have been dogging it out a lot.

I picked up a Dashhawk along with a CP-E mount and installed that on Monday. Consitently seeing mid 18 psi of boost at peak, tapering back to mid 16's. Yesterday was very cool out so I saw over 19 then. AFR is in the mid 11's. So far no sign of knock retard. Will do some data logging in the near future and will post the results.

 

[anm6]

Thanx couper keep us updated. I'm still trying to get a before and after dyno done,... NO $$$$

 

[anm6]

Ok guys great news,Just got off the phone with Chris, there was a small issue with the
calibrations on my tuner( Holding boost). They fixed it and I have to remove the tune I have now reprogram my tuner and reinstall it. He also told me that they where getting their shop car back, Getting a Cobb SRI and going to get the info on that also.
he also asked me to help them with the Beta tuning on it before they release it.. It will be a few weeks for the Cobb but all is going great with them. A+++++.

Thanx Chris!!!!!!
