Right!More boost. More flow. More go! It should not be very long till the stateside tuners start to release their own Stage 1 tunes.
Not doing anything to mine any time soon. There is a bit of a learning curve attached to learning to drive the original 505HP to its potential. I'm happy where it's at for the time being.
With an Italian car, reliability is a crap shoot to begin with, but adding 100Hp is no joke. Have to see some customer/magazine reviews, I guess.I talked with Pogea back in Dec, you have to send in your ECU to get modified. Easy way to loose a warranty but worth it!
Word to the wise.. never do a mail-order tune and especially on a forced induction car.I talked with Pogea back in Dec, you have to send in your ECU to get modified. Easy way to loose a warranty but worth it!
Hi Eric,There is no way the tuner can account for all of the electronic variable and measurable changes that can exist from car to car. On turbo cars, the number one calibration consideration is the ECU's control of the wastegate turbo actuators through duty-cycle driven solenoids. Those solenoids and their overall sensitivity and calibration definitely does vary from car to car.
Some people want the extra power, and we can often do this without risking the warranty. I can't give specifics yet because we don't have anything for the Giulia at this point, but we will.Why tune and risk voiding the warranty when most owners will never be able to use the full potential of the QV in stock form?
I must be older than you M. I remember when tuning a car was done in stages.[email protected]
I'm old enough to remember when getting a tune meant actually buying a "chip" removing your old one and then plugging in the new one..
everybody thought they were getting more HP when in reality with N/A cars what you most likely got was the rev limiter removed and maybe better throttle response...and that's about it...now with anything FI the game is different...dialing up the boost means many gains and many potential issues....
that's why i agree with Eric.
better to have a hands on approach as opposed to mail order..
when I had DINAN goodies done to my car they actually send an engineer to the dealership to tune the car once all the hardware was installed on the motor...
@Racer been there done that in my American car era:grin2:I must be older than you M. I remember when tuning a car was done in stages.
1) Headers, big mouth air filter canister, and hacking off the mufflers. Don't know if it went faster, but it sure sounded faster.
2) Bigger carburetor.
3) Changing the cam shaft. I still remember an add for "3/4 race cam". What a bunch of hype.
4) Stage 4 was attempting to port-match the intake & exhaust ports.
5 & 6) These stages required pulling the engine and splitting the cases. (some engines have cases that do split, some don't)
I would amuse myself at times by adding all the parts in the back of the magazine together. This header claims 50hp. That intake claims 25hp. The 3/4 race cam claims something unrealistic. Spark plugs, ignition wires, ... My list of parts more than doubled the stock power, and it was all just bolt-on parts from multiple companies. Possible? Doubtful? Keep in mind that these claims didn't rely on any other mods.
Truth is that it was (still is) a complete system and one part effects how all the others perform. You need to think of it as a complete system and how each area effects the others. Does the exhaust flow well enough to support the big cam? Do I have enough flow to support the big carb or will it just stumble? When I start making more power, does the fuel pump flow enough to feed the greater power? Now that I have a higher revving engine, will the ignition still work at the higher RPM? (points cam float or coil can't recover) Will I get valve float at this newer higher RPM? Who ever asks, "Where will my new torque and HP be?" Or, "What will my new torque and power curve be like?"
It's not just as simple as adding a in-line electronic plug thingy that adds +5% to everything without any knowledge of what's coming in and what's going out and what is safe and unsafe.
Well, my father has a 66 GTV with side drafts. I have a 73 240z with points and side drafts. I have a 70 Ford F250 with points. Bought a new dwell meter recently and a new timing light. I'm no stranger to using an air flow meter or mercury gauges and syncing carbs. Been through plenty of bikes (motorcycles). Do all my own wrenching including engine rebuilding as necessary.@Racer been there done that in my American car era:grin2:
Was referring to cars with no carbs, and that were forced induction, whether it be Trubo/SC/ or bottle fed
Came to the conclusion I prefer N/A motors...but alas that ship has long sailed when talking new....
Can't remember the last time I saw a car with points LOL
If you want adventure get your self an old alfa without FI and try to tune the side draft carbs..music to my ears!
Greg. Is this like OTS tuning similar to Cobb? I'm not new to OTS tunes from marque vendors and even some open source tuners. Got any dynos? or plot maps?Hi Eric,
Not long ago you would have been 100% correct. However there have been some recent developments that really make this issue a thing of the past, at least as far as the newer Alfa Romeos are concerned.
The modern Alfas do indeed have duty-cycle driven solenoids, and they do vary from car to car. However the new ECU's have a learning procedure and both long term and short term trim adjustments to dial in exactly the amount of boost the ECU commands regardless of the component variables. In other words, after a reflash, the ECU will start off with low trim values and monitor the boost. It will then trim it up via the solenoid duty-cycles until it sees it's target value on the various boost sensors. If it goes too high it will trim down. This is a very safe and reliable system, and as far as I know all the new Fiats and Alfa Romeos are set up this way. The only downside is that after a change in your ECU tune, or certain other components the ECU will need to "relearn" its trim settings, which can take about 1/2 a tank of gasoline worth of driving.
This is my first post here, and I realize that what I am saying may be new to a lot of folks. Please keep in mind that this is based on actual experience. At my company we tune the ECUs for most of the new Alfas and Fiats, and we have been offering tuning solutions for the older cars for a long time.
I really don't want to post anymore in this thread since it's a thread about products from a competing vendor.Greg. Is this like OTS tuning similar to Cobb? I'm not new to OTS tunes from marque vendors and even some open source tuners. Got any dynos? or plot maps?
