igniter? would be my first thought swap it on another supra and see if it responds the same

I am curious about this also, i have lexus is300 5 spokes. anyone?

gotta love those goldmines. unfortunately there are only two supras in junkyards around me, and they have both been stripped pretty well...

alright, ill try going back to stock FP, i just wanted to check and make sure pulling that much fuel was not going to push the timing dangerously far, as some people have warned me.

well, little update i re tuned my safc, and created a tune point right at the lean spike so that i could add fuel at only that point. so i took care of that spike, and that one is normal. BUT it created a new one at 3000 rpm same deal, 3000-3200. same spike, to mid 16's anyone?? i could...

thanks for the response, thats good to know can anyone chime in to let me know if i am endangering my car in anyway by pushing timing with the amount of fuel i am pulling? thanks

Hey Guys, So I have my SAFC tuned pretty well, but i am trying to get it fine tuned, and get some peace of mind clearing up a few questions. i read over the tuning thread in the ref section, and a few other sources as well. i have it tuned as recomended. the few questions i have are...

IIRC for the less serious codes the ecu needs to detect them for three consecutive starts in order to keep the cel lit. please correct me if I'm wrong

did you get like the driftmotion kit, or just the fpr? if you got the kit, you just run from the return line port on the fuel rail, to one side of the regulator then from the bottom of the regulator to your return line. then pick a vacuum source, set your desired pressure, then connect...

or boost leak, or bad 02, or leaky injector, basically anything that could cause an incomplete combustion, or rich running.

i'll give that a shot, im just not sure how im going to tune up high, because i am already pullling 25% up high.

Hey All, I recently got my PLX wideband installed, and properly tuned my safc. it runs perfect through almost the entire rpm band, whether i am under boost or just cruising, except for right from 2000-2150 RPM on the low throttle setting of the SAFC. Under normal (not WOT)...

so were you able to just tap into it? or did you have to add a capacitor or something to it to keep the reading the same?

thanks for the help, got her taken care of. i must have had right hand drive mounts or something on my ecu, idk if theyre different, but i "adjusted " them to fit

there are literally hundreds of this exact post all over this forum, search it, research, and make the decision for your self. the decision is going to be different for every person.

thanks for the suggestion, i no longer have my 7m ecu (got rid of it 8 months ago, and its been that long since i have seen it installed) So it sits like you described, i am assuming with all the wires leading toward the passanger side? thanks

sorry to bump a thread that is probably useless to everyone else, but can anyone help me out here?

Does anyone by any chance have a pic of their stock ECU bolted into position behind the glove box? Or is the mounting for the 1JZ ECU somehow different from the 7M ecu? I can't for the life of me figure out how to bolt my 1J ECU into poisition... Thanks, -Trevor

alright, then go and blow up your w58 twice, and you have already exceeded the cost that you would have paid for one r154

a W58 won't be very smooth shifting after running 450 rwhp through it for a while... r154 ftw and for the 1j you can use all 7m clutch components, all you need is a 1/2 j flywheel and bellhousing
