i wrote this in the tech forum as a kinda response, then i saw there was a forum for DIYer's
feedback is always good
a small history as to what im doing and why the magasquirt choice.
so i opened up the exhaust with 2.5 inch pipe and 23 inch glasspack. it gave a wonderful low tone, (like an old V8 at idle) and a nice boost in hp at about 3500+ rpm, most noted at 4k almost like a power band on a kawi. but as one would expect there was a great loss in torque and hp at the low end. so i pulled all the intake and smog equipment, yes i took out the egr, and removed the prewamers too. i fabed an intake rerouted wiring for mass air flow and iat. the increas in throttle response and low end power is substantial to say the least, but the mods that i have made have come with two problems. first, my sidekick came from ca and has a 58b5 cal-fed ecu. this ecu requires egr feedback to run properly. now ive heard that you can use a 58b30 because it doesnt require egr in its programing. however this dosnt fix my second problem. problem two. while reworking the intake system i removed the... umm... the thing that sends sig. for cold idel. so adding the magasquirt would fix both prolems and also allow me to remove the mass air flow sensor, and add a larger cm thorttle body. i also hope to make up the for the loss of back pressure and related valve overlap effect without cams in the ability to fine tune or change ign, and inj/pulse width.
hmmm... i think i got it all
