[urq] ABT ignitionbox

Sat Sep 28 01:19:51 PDT 2013

--- Hi ,   I don't have a Chip or Knowledge to modify the ECU,  but If  better starts, and increased power, and the like are desired,   I would recommend installing,  Electronic Fuel Injection and Spark control  of  Some kind.    I had someone install a , MegaSquirt system , in my '85 Urq WX.    There are a few builders of MegaSquirt based systems out there and there is , 034, which has a similar system for sale.     The difference in performance and power is Remarkable.     It might be something to look into instead of dealing with Mods to  the stock system.    Megasquirt is an open type software and was developed for DIY ers..  ,   but as things went along , there became people who used the basic software and developed it  and built complete hardware  packages for sale.   The "package" I had installed was from, diyautotune.com .   I was going to use the , 034motorsport.com  system but the person doing the work wanted to use the other Co.   If you choose to, you can do your own programming with a PC laptop.   That is what I wanted.     Anyway,  I thought I would just mention the alternative for the situation.
