    So I have a line on a charger for 6 bills. I was reading on the TRD install PFD that they do not recommend putting them on 95and 96s due to the ecms not really able to deal with it. The say 97s and on basicly.

    What do you guys think, any one have one on a 95 or 96?

    From what I have read you need to Swap your ecu from a 97 or later taco, not sure why, but I'm sure some more informed folk will chime in.

    Yea the TRD stuff said that this was not so good.

    http://reviews.mtbr.com/video-al-pesto-riding-in-san-romolo-with-floriane-pugin

    There has been some confusion as to which
    vehicles the supercharger works best on.
    Please clarify.​
    While the supercharger will fit the engine, the Electronic Control
    Units (ECUs) used in 1995 and 1996 T-100 and Tacoma trucks
    do not respond as well to supercharging as do the 1997 and
    later vehicles. For this reason, TRD does NOT recommend the​
    supercharger for the 1995 and 1996 Tacoma and T-100 trucks.




    Do I have to change the vehicle’s computer
    (ECU)? Do you suppose it’s possible to change
    out the 1995 or 1996 computer (ECU) with the
    ‘97 or ‘98 model?​
    TRD does NOT recommend using any computer for your vehicle
    other than the one that is made for the specific vehicle by Toyota.
    TRD offers no modified or alternative computers, as the TRD
    supercharger has been designed to be compatible with the factory
    computer.​

    Why doesn't TRD recommend the supercharger for 95-96 models?
    - The reason they are not recommending the supercharger for 95-96 years is because the truck's commputer (ECM) can not deal with the fact that there is not enough fuel. What happens is the ECM tries to fix the problem by retarding the timing. (It does this so much that you want gets as much of a HP gain.) Another reason is the ECM has two operating modes, open & closed loop. The ECM stays in "closed loop" when the truck is under about 80% throttle. It does this by changing the air/fuel mixture from rich-lean-rich-lean, to save gas. Once the throttle is opened more than about 80% it goes into open loop where the air/fuel mixture stays at its maximum efficiency. Since there is not enough fuel under full throttle; the 95-96 years will not go into open loop with the supercharger which robs the HP. To correct this problem see, Fuel Modifications below.

    Just get a 97 ecu.

    95-96 ecus retard the timing some it doesn't run right.

    Just buy an exact 97 ecu and you'll be fine.
