    Vtech Map Editor Cost (maps seem lean for my setup/location)

    Anyone know what it runs? Seems the maps for my setup/location run lean. Im running the vt1100 8500 stock sc tune. Every bolt on piece except a fuel pump and at 60 psi wot was at 13 afr - idle around 14.5. I pumped it up to 68psi and got to 12.1wot 14 idle. Weather sucked windy and wavy but I was able to do a few runs and they all where about the same at 68psi. Maybe they have a map with some added fuel but I did not see one for the vt1100s

    You need about 50 times that much data. I personally never tune with a pressure regulator. I always tune fuel with a fuel table.

    I like to look at about 30 min worth or more of data to see a clear AFR pattern to develop. This happens to be about 28 min data log.

    I figured I need to do it longer but do I make the log at 58 psi and hope the motor dosent get hurt? Or bump it up to 68 where it was safer?

    try any other map
    they should not be that lean

    also using the logger and map editor you can add fuel to your project fuel map
    there is also a "autotune" you can use

    I need to find out the cost of the editor. Also the map I was using didn't show a number for fuel was the 8500 stock sc. So I am going to try the 8650 with 172.

    Try a different tune. I bet because it is made for the stock SC it doesnt add much fuel with the 1100 injectors. Looking at the warm fuel map for that tune it shows 161.7. Try the VT11 8650 165 36 39 Agr 102, VT11 8650 169 36 38 Agr 101 or VT11 401 Jesus.

    Did your injectors fit ok? I got a set and the OEM clips wont fit. Almost like the injector needs to go up into the fuel rail a hair more or the side window (rectangle) of the OEM clips need to be opened a hair?

    When I measured my VT11 compared to stock, the VT11 is 1mm shorter (o-ring to o-ring center). However, don't see why you need an OEM clip at all.
