I have access to wiring diagrams for any vehicle available in North American 1983-present. Sometimes I can cross it over to Rest Of World cars. If you need schematics for anything, feel free to email me. alandaeric at hotmail dot com

After months, no, make that years (since before v2.2 came out)of researching, I finally could not wait so I botched together a fuel pump system, installed my wire harness, plugged my v3.3 in and hit the key. Fuel pump running, smell fuel in the engine, but nothing. Then I turned the fuel pump off and cranked for a while figureing it was just flooded when KABOOM, I was sure my exhaust was dust, too bad for it. Shifted the firing order 180 degrees and add a touch throttle and vrooom. Ran like crap but stayed running as long as I kept a touch of throttle. Need to move it now from the front yard onto the driveway so I can weld up the O2 bung and start tuning.
1 concern I noticed that I was concerned about before I started was the map sensor. I am using a Honda map sensor, changing to a different one is an option but I would like to avoid it if possible. The lowest map reading I got when I let the throttle plate shut was around 76 kpa, I kind of expected something lower, is this "normalish" considering how bad it is running etc.?
Ok, hooked up a scanner on a car at work today, realize I am right and I should expect around 30kpa or so at idle. What can I do to configure this MAP sensor to work?
76kPa vs 30kPa is a huge difference. -32kPa is the maximum (negative) offset that can be applied (kpaoffs=00). Try it. Beware that MegaTune cheats you with this, the unit is not mV (for a long time) but kPa. So at least verify with mcd dump.
If you can adjust kpaoffs and kpafac so that MAP reading is close, the remaining error can be corrected with mapping. Actually, mapping can be done even with very incorrect values (if the trend is otherwise OK; the resulting ve might look awful), but good readings are better in general.

Will this VFD work easily??

It's a serial VFD, it will not work. You need a paralell interface with a 44080 compatible command set. Note that VFD displays often have small incompatibilities with LCD displays even if they are listed as LCD compatible.
WISH LIST
- I would like to have a configureable speedo output. (not for my project)
- Drive by Wire, need some serious help with that one.
