    B20A stock ROM on OBD1

    What im looking for is a chip (or someone that can make one) that i can simply stick in my OBD1 ecu that will run it on the stock fuel maps it already has.
    So if any one you guys with ecu chipping stuff i would be interested in getting a copy of this map

    Re: B20A stock ROM on OBD1

    I've been trying to find this for a long time.

    Uberdata and Crome and others can't import the obd0 maps for the PH3 ECU properly.

    I've been trying to even OPEN the ph3 maps properly so I can throw them in a .bin file, but have been unsuccessful.

    I'm basically using a GSR/LS hybrid fuel/ignition map setup on my b20a, and we've adjusted fuel big time to make 13:1 a/f's at WOT all the way through the RPM band. But I feel like a fresh PH3/b20a map would be a much better base.

    I had one built and if I can find someone to load my chip into an email file you can use it. Its basically a simulated rom, not tuned. Its very close for my build but mine isnt stock. Ive got larger intake, exhaust, cams, ignition but if you know how to import it Ill try

    I burn my ROMs right onto my own chip.

    The .bin file that it gets burned from - that's all I need.

    Something that will import into an obd1 burning program to burn onto a chip. If there is a 'chip' like it, the ROM definitely exists somewhere!

    That makes sense versanick but mine was loaded for me. I suppose I could bring my laptop out to my car and extract the .bin file from the ecu if I knew how. Do I just plug my ecu via usb into the laptop and open the program used to create the file or do I need some other equipment

    I have a copy of thegreatdane's OBD1 ROM for his B20A at home.

    I'll host it when I get home.

    Carotman,

    Do you mean host it on your web page?

    We were thinking that using LS ignition maps, although not too far off at high RPM, the low and midrange aren't even close because of the completely different stroke on the b20a.

    I was looking around to see if sites that sell Stroker kits for the b18 might have stock maps that they give people, but I've sent a few emails out with no luck.

    So a b20a ANYTHING obd1 map will be a boon.

    Isn't there a b21a1 obd1 ecU?
