    amc 304 conversion

    Hello
    I wrote this in my introduction but i think more members will read it here and i fear it will become a longer thread.
    I have a Jeep CJ7 with the 304 engine, i want to implement a tbi systemof a chevy astro ."I could get my hands on the TBI injection system of a chevy with 4,3l engine and automatic gear.I could grab nearly everything without the VSS. The ecu is the 161 96395. So what do you think,can i implement this system in my Jeep?
    Problem i have right now is, i can not get contact to the ecu with usb ttl cable and all the diagnostic programms i have found. I connected the ecu to a battery, is there a minimum voltage for reading the ecu?, I can here the fuel pump relais and the ses light comes on when i connect to the battery!"
    Dave already showed the link on two threads with moates and here in the forum.
    What would be a good memcal for this car and this engine.Does somebody else already change the carburator of a 304 to TBI.
    Moates says i will have problems because the memcal (ecu) is from a 6cyl engine while the 304 is a 8 cyl.Can I switch off the VSS in the BJBB.bin
    A lot of questions --in this post.

    The 16196395 usually requires a VSS. The 16196395 can use a 2000 Pulses Per Mile VSS.

    Some VSS is options: https://www.ebay.com/itm/85-89-TPI-R...5.c10#viTabs_0 and https://jagsthatrun.com/collections/...s/speed-sensor

    The VSS Can Not be disabled in the .bin file.

    Maybe there is way disable the VSS with some wiring harness modifications?

    And you should try to find a V8 memcal.

    Thank you for the hint, but I think the 306 is much different to the 304.For the memcal, i have already found some bins here in the forum for the 16196395. My actual problem is that the electronic part of the chevy distributor does not work together with the reluctor and hall sensor of the amc distributor. I have to order a distributor from a chevy taho, blazer or caprice with the 8cyl engines. The 4,3l is a 6 cyl. My second problem is still the connection to the ecu. I have a fdti usb cable and a CP2102 (silicon vally) usb ttl cable. Both do not get connection from ehack (winaldl, freescan) to the ecu.All the other parts are already in the car. I had to build two adaptor blades for the TBI to the engine. A thicker one as connection between block and TBI and a thin one between both. Because a channel on bottom of the tbi was right over the mounting screw of the thick blade :-)

    There are several options available for a distributor, and several options for connecting to the 16196395 computer.

    The GM 8 pin HEI is a good option for the AMC 304 TBI. http://performancedistributors.com/w...44-300x300.jpg

    This article shows how to convert an AMC distributor to a GM 4 Pin ignition module, but the 8 pin module can be used instead of the 4 pin. https://www.hotrod.com/articles/conv...ion-to-gm-hei/


    The GM remote coil is a good option for the AMC TBI. http://www.gearhead-efi.com/gm-ecm-p...s/coil-efi.jpg


    The ALDL Cable from ALDL.com is a good option to connect with the 16196395 computer using TunerPro RT software. http://aldlcable.com/products/aldlobd1u.asp and http://www.tunerpro.net/downloadApp.htm

    Hi Dave w thats exactly what I tried with the 8 pin module, but didn't work. I think the impulse from the reluctor and sensor is too weak or i have changed cables from module to distributor, i will try again!
