    Innovate Motorsports on Rice Boy's

    in Non Tech Board

    Posted

    I was thumbing through the Innovate manual and near the end I found this 'tid bit'...

     

    "Very often one can see small front-wheel-drive cars on the road with huge wings mounted on the

    trunk lid. But there’s no corresponding aerodynamic down-force device in the front. Of course, in

    the majority of cases the wing is there for the ‘cool factor’ because many race-cars have wings

    (birds do too, but birds also have no penis)."

    Which ECU Should I go with (FAQ)

    in Nissan RB Forum

    Just ask what is speed os comathematical and main processor and main plate

    that should be enough for your choice.

     

    From Wolf's website RE:V500....

     

    "Latest 32 bit processor running at 40MHz with Dual Time Co-Processors, giving precise sequential delivery of fuel and ignition and supporting all other functions including high speed Datalogging with no performance loss."

    Which ECU Should I go with (FAQ)

    I'm looking for technical information here. And I'm sure it would be a good catalogue.

     

    So lets ditch the "experience thing" until we narrow down the top 5 ECU/ECM's for RB engines in regards to what's beneficial and what's not, as well as price.

     

    It seems to me that you're looking for three things...

     

    1) Spec sheets.

     

    Wolf's specs....

    Wolf's 'Highlights'...

     

    http://wolfems.cart.net.au/details/635751.html

     

    I'm sure you can easily find the remaining brands you're interested in on their websites.

     

    2) Current retail price on a universal Wolf V500 is approx. $1500 US. I offer a discount to donating members of HybridZ.

     

    3) Requirements for an RB.

     

    Bernardd covered that, if indirectly. If your motor goes "suck, squish, bang, blow", virtually any of the available systems will run it. Some will require you to use a different ignition system, alternate sensors, and a custom harness. Some will support sequential injection and ignition, others are batch only. Some will allow individual cylinder tuning. Some are easier to tune (won't find that in the specs.) and so on. But, they all have one thing in common... they are all capable of running the common 4-cycle engine. What features are important to you?

     

    As for Wolf, you can buy a "Direct Fit" for an RB. This means unplugging the OEM ECU and replacing it with a fully configured Wolf EMS, compatible with all sensors & ignition system, and includes a base map. Plug it in and turn the key. You will have to fine tune it for your specific installation if you want peak performance.

     

    However, I would like to add, these systems are not 'Black & White'. If you are a creative person, it doesn't stop with the spec. sheet. I'll leave you with one example...

     

    With Wolf V500, there are 13 auxiliary inputs and 15 to 27 auxiliary outputs. For some people, using the Aux's. to switch on a light upon exceeding a temperature point would tickle them. Maybe you're slightly more sophisticated and would like to see a sequenced shift light. Or, install 3 potentiometers on your dash and use one each for adjusting fuel curves, timing maps, and boost on the fly. Maybe your perfectionist nature takes over, and you decide to install a fuel temp sensor and use it to modify fueling, timing, boost, etc., or limit RPM because oil is not up to temp yet. How about pulse width modulated water or meth injection? Generally speaking, idle quality, fuel economy, and emissions are improved when an injector is nearest the intake valve... but HP is typically improved moving it further away. How about two sets of injectors, running blended or RPM switched? There is no end to the possibilities. How creative are you? Maybe you'll pioneer a new way to use auxiliaries?

     

    My point is, I have know idea how a person lists all the possible capabilities of a system (read technical limitations), when they have not all been invented yet. EMS systems are significantly influenced by the character of the installer/tuner, not just the spec. sheet.

    I've never been one to say that one EMS is 'Best'. They *all* have their strengths, weaknesses.... and unfortunately bugs. Add to it that they are so complex that the each have their own character. Just like people, some character traits are welcome to some, but unacceptable to others.

     

    By now, most of you know I sell/support Wolf3D. Is it the best? No... Neither is Motec, 883, Haltech, SDS, Megasquirt, Electromotive, EFI Technology, Microtech, etc, etc, etc. Not one available system is perfect for everyone (and there never will be). Anyone that tells you one system is the 'Best', doesn't get it.

     

    If money/time were of no consequence, I would choose a different system for each specific application/car to take advantage of its individual strengths, per its intended use. This is not a reality for most of us. This is the exact reason I elected Wolf. In my opinion, it has a great combination of features, ease of tuning, flexibility, reliability, and price. Bang for the buck is high.

     

    In reality it boils down to this... customer support is KING. If your dealer can make a system work well for YOUR application and needs, then it makes no difference what name is on the side of the box.

    Re: Corvettes

    Perhaps these were five Corvette owners who didn't know what they were doing? This was an SCCA SOLO2 autocross in 1998.

    http://www.sfrscca.com/solo2/Results/1998/Slush/round6.html

    (note that some cars finished in 40 some seconds, but that is after it started raining and they were only allowed one lap instead of two. We and the Corvettes raced before the rain)

     

    I’m not following you...

     

    If you’re speaking of the 5 entrants in SS (the above link), they were all clearly driving in the rain... they were running 80+ seconds vs. 40+ earlier in the day.

     

    Coincidentally, you happened to pick a driver that I know pretty well. Don Mckenna is my uncles father. At that time he was driving a bronze C4. You may remember it...

     

     

    mckenna.jpg

     

     

    Don has more trophies than you can shake a stick at. From first hand exerience, I can assure you that Don’s driving abilities are not lacking. He *is* National caliber. The SFR SCCA has a small salute to him on thier website, next to the above picture.

     

    “Don McKenna is one of the smoothest drivers in SFR, some say. It's clear that he can make cars do things that many believe to be impossible. Don has passed this historic vehicle on to a new generation of McKenna drivers, and now drives a blue Gran Sport.”

     

    A C4 has got to be one of the WORST cars ever built for the rain... I have to dismiss the above link.

     

     

    As for National trophies in Corvettes, I thought I would find a few years worth of records for you. I stopped at the first records that I found (2004) becuse, well, I think that one year makes the point on its own.

     

    Super Stock

    Top 14 positions are all C5’s

     

    A Stock,

    First and Second place, C4

     

    A Street Prepared

    First and Second place, C5’s

     

    B Street Prepared

    First 4 positions, C4’s

     

    Keep in mind there were over 1200 drivers entered that year and that these 4 classes make up THE fastest times of ANY street legal cars.

     

     

    Enough about Vette’s. Your Supra idea is interesting reading... keep it up.

    Regardless of who or where they come from, I think it is safe to say that they will always be refered to as the Ron Tyler Diff Mount. Like the cresent wrench, vise grip, or the ever famous regardless of who manufactures it....monkey wrench.

     

    Thank you... I suppose there are worse things to be remembered by? :D

    Gary,

     

    It appears that pre-'72 cars used a different bolt spacing for the retaining strap... the remaining S30 cars should be alike. Therefore, this will properly fit '72 through '78. Minor adjustment to bolt spacing would be neccessary for '70 & '71.

     

    P.S. we need to catch-up sometime.... are you autoXing this season?

    Beautiful engine bays guys, but how do you go about hiding the wire harnesses.

     

    Asking this is like asking how to paint a portrait... there is no right or wrong way... just art. Everyone here has a different style, just like every painter.

     

    Route them as you see fit... you'll then have YOUR style :wink:

    How many Corvettes do well in Autocross? The ones I raced appeared to have a hard time staying on the track and never seemed to be able to use all their power. They don't have enough room to throw the weight around.

     

    Tangental to the topic, but I thought I'd answer your question... C4's and C5's have collected an impressive number of National trophies in both Superstock and Street Prepared classes. In fact, the very existence of Superstock lies in the hands of the C4... pre-C4, A-Stock was "it".

     

    If you're not seeing fast Vette's, you're not looking in the right places.

    Im curious how Ron feels about my making these mounts.If your out there Ron, speak up. I would hate to over step any bounderies here.I made this for my car and if you prefer that I keep it at that, then I completley understand.

     

    Honestly, I can't believe the stir this 'whim' caused... Have at it!

    Great discussion guy's.

     

    One thing that comes to my mind is, no matter how 'ideal' the suspension, an S30 is a very flimsy car.

     

    You could have Porsche, Ferrari, or McLaren design the suspension, with an unlimited budget, and you'd still have a problem. Granted, it'd surley be an improvement over the original... but there is still much work to be done.

     

    One of the reasons modern cars work so well AND keep noise to an acceptable level is because they are RIGID. This single attribute does wonders for a car... dissmiss it, and be dissapointed.

     

    Further, keeping a Z streetable while you reinforce it, is not for the faint of heart.
