    40th annual Colorado Concours on June 4

    I'll be there in the "Parade of Decades " or some such section. I'll bring along a few parts for Spencer to caretake for fellow Colorado NSX owners. We received an offer for our house yesterday that we are likely to accept. Now all we have to do is find a place to move to that is suitable for...

    91-94 ECU reprog (Honcho ?)

    A local electronics shop in Europe can make the (minor) modifications to any 91-94 ECU, your present one or one you buy. If you hate any changes you can easily plug in your original "chip" and do nothing else -- back to stock performance. If you really want to get into this (which I highly...

    Tuning the NSX 3.0L Using the OEM ECU

    Is this the final output from my TableAnalysis Program? This is a result of a ~4 minute logging run with 5 pulls into VTEC. I've taken each individual pull to examine possible fuel map alteration, and recombined them into this final chart. It is broken down into each Load/RPM pair from 8500...

    Tuning the NSX 3.0L Using the OEM ECU

    Today I finally got my laptop capable of running my full TablaAnalysis Application. This means I will start (as soon as the snow stops) going out and tuning my car as opposed to writing the application to do it. Here is an exemple of the results. These are two completely different runs made 2...

    Tuning the NSX 3.0L Using the OEM ECU

    Here is a not so short article about street tuning the NA1 NSX. Contrary to popular opinion, it is more than possible to do this with the OEM ECU, and has been for about 10 years. Some intrepid individuals have partially cracked Honda’s ECU code and “published” the results here on NSXPrime...

    Tuning the NSX 3.0L Using the OEM ECU

    Yes, definitely interested! I just got out of a 2-day stay in the hospital with some kidney issues, so this may not be very coherent. I've managed to reinvent the wheel with a table analysis of the existing function that is able to isolate individual pulls during a logging session. I've never...

    Tuning the NSX 3.0L Using the OEM ECU

    My base bin file is John's, which has been adjusted for injector dead times. Those times are not identical to some of those posted elsewhere, although they are very close. Again, looking at the quite flat AFR curves I get from all the tables, there doesn't seem to be much here. It has to be...

    Tuning the NSX 3.0L Using the OEM ECU

    Yes, everything is working well and consistently. I've made several pulls through 1st and 2nd gear up to redline and my analysis tool works great, but I cannot for the life of me get them to attach here. It is either too large (>100000) or I don't have permission to attach. Every time I...

    Tuning the NSX 3.0L Using the OEM ECU

    The bin file is already in the Google Docs folder and I just added the adx and xdf to the TableAnalysis folder in Google Docs (url above). nsx_v1_0_alpha.xdf nsx_v1_0_alpha HT - Copy.adx These will give you the color coded dashboard that goes with the color coded TunerProRT graphs. The...

    Tuning the NSX 3.0L Using the OEM ECU

    Big time --- well it turns out you don't change pulse widths very much to get significant AFR changes. You can read all about my tuning thought processes from the Google Docs page. Down load my app and in the instructions there are all the illustrated notes I made during about 6 alterations in...

    Tuning the NSX 3.0L Using the OEM ECU

    I went out this morning to check logging, and my WBO2 sensor is still not working. I'll take it out to let it "air out" this afternoon and see what happens. The car still went into VTEC with no trouble and only the 5 - 2 CEL on a pull through 2nd gear. It was fine in 1st gear -- likely not...

    Tuning the NSX 3.0L Using the OEM ECU

    Well, the damndest thing has happened. We took a road trip this past week to Gunnison, Durango, Chaco Canyon, Grants, NM and Albuquerque. Prior to leaving I was ~150 miles short of my third oil change to Mobil 1, so I changed it early. During the first part of the trip my VTEC started...
