  1. What would be the advantage of running this over the stock ECU if are still running antique sensors such as our AFM and TPS ect?

     

    There are a number of advantages AND disadvantages. Its not for everyone.

     

    Many people have installed cams, exhausts systems, etc, on the L-Jet EFI cars and it becomes a real compromise. Tuning out the flat spots, keeping fuel economy, and so on, becomes a real chore (if not flat out impossible). The most obvious benefit to this strategy is being able to take advantage of your modifications with ZERO down time.

     

    As far as the AFM and TPS are concerned, I'm 'ignoring' both of them. A vacuum line to the ECU is all that's necessary for load and acceleration enrichment (replacing both the AFM and TPS). Yes, you'll get better response if you use an actual pot. style TPS, which is why I wired up the 3 existing TPS wires so that you may add one at your leisure. Then its a simple matter of telling the software to use TPS instead of MAP for transients. Currently, the MAP based transient response is about on par with stock.

     

    The idea is to provide a means of growing the system to meet your needs or wants over time. Even adding a turbo wouldn't be unreasonable... all the remaining Wolf features are still there to take advantage of, as the individual chooses.

  2. The front story...

     

    Yesterday, I fired up my S30, equipped with a V500. I know. I know... its old hat. Well, I did something a little different... I plugged a V500 into a stock EFI harness. No modification's. No endless nights. No explaining to the wife... well, you know.

     

    I simply robbed a stock ECU's connector and wired it up to a short V500 harness (about a foot long). Plugged it in, uploaded a configuration & map, and it started on the first attempt. Drove it for about 1/2 hour today. Made a few adjustments and it runs like a top.

     

    The back story...

     

    For some while now, I've been wanting to offer a 'Plug n Play' Wolf3D system for the L28E. One of the setbacks was V4's inability to read a negative coil trigger. The only workaround was doing some re-wiring, something I wanted to 'avoid at all costs'. I wanted stupid simple. The key is V500's ability to be triggered by the coil, as does the factory ECU.

     

    I've been talking with Wolf about producing a proper adapter. Its not etched in stone, but its looking realistically possible. This means an entire 10 minute installation time... and turn the key.

  3. I read that, did that, everything seams to be normal. We got it operate fine at rest but once you put a load on the car ei put it in fist and try to go, the car bogs and does not want to get RPM. it wont even go past 1500 RPM. Put it back into nuetral and let it idle for a minute and she runs ok but not back to good.

     

    I'm not sure if you answered this or not... when you unplugged the WT sensor, did the car run the same or different? If it ran the same, there is a problem in that circuit (and quite common).

  4. Fortunately, I came to my senses and realized I was making this harder than need be. New strategy...

    As round as round gets.

     

    Where the aluminum 'cap' begins is where the CF will visually end and the TB flange begins. This will give me a short, perfectly round neck to bond to.

  5. One of the critical elements of the plug is the TB interface. A bonded aluminum flange is the plan (a proper bond will shred the CF before the adhesive fails). Dimensionally, I have some wiggle room in machining the flange to final diameter. But, the plenum needs to be ROUND for the adhesive to work correctly. An easy way to get it close was to remove the backside of a hole-saw, and power by hand...

    Its not *exact*, but its close enough to finalize during the finishing steps.

     

     

     

     

    Blended in the new inlet...

    About another hour or two of roughing in and it will be time to start the finishing stages.

  6. Greetings,

     

    I will like to know if anyone here has/had any experience with Electrical Power Steering (EPS), some of the new cars already have then installed i.e. Acura NXS, Honda S2000, Toyota Prius, etc... The little that I know is that EPS provides power assist even when the engine is stop (I assume that the ignition key has to be in the 'on' to avoid steering locked and to sent electrical power). It also improves fuel economy due to it is lightweight. The DC motor consumes energy only when power assist is require, along with that EPS is powered by a 12V motor and is not dependent on the engine for its power source, so the steering feel is not affected when the engine is shut OFF.

     

    There is a member here that has perhaps, a Z ready kit for sale on his web site, out of his company respect I rather not advertise his name, since I just will like to know if anyone know, or driven a car with the such.

     

    Thank you,

     

    Alex

     

    As I understand it there are two variations. The NSX and S2000 have the assist built into the rack, whereas some of the others are built into the column.

     

    One of our vendors is offering the latter style... http://forums.hybridz.org/showthread.php?t=130027

     

    P.S. Black text is easier to read :wink:
