yesterday i took out my car to tune my safc and to try it out because i have put some mods and haven't tested the car right cause i was untuned. ok so i was tuning my afc and when i was almost finish i do a roll in 1st gear and at 7500 rpms i change to 2nd but when i shift, my car just shut off, and lol i crap my pants cause i taught i broke the engine, so i go and try to start my car and it starts and shuts down and i was like wth, so i open my hood and saw that my tmic was out of the pipe that goes to the throttle and i put it back and try again and bang it stars like nothing has happened lol, my question is, does our cars have some type of sensor that don't let the car to start without the intercooler???? cause my bro has a turbo car and it stars without a intercooler and i was just confused????

thanks for any help

It's basically like a big vacuum leak.., and your bro's car i'm not too sure about someone else with more experience can probably come up with a reason why thats possible if even?

Uh, yeah if an IC pipe is completely off, then the mass air sensor isn't getting any flow through it, so the ECU has no idea how much air is getting into the engine.

lol if you mean why his car dont shut off if it doesn't have an intercooler, i don't really now but i think beacuse he has a standalone microtech, he just started and he starts fine without the intercooler lol but he doesn't drive without it for sure lol.

thanks man lol you're almost everytime the first guy that replys to my theads everytime i put one.

With a lot of stand alones, there's air flow meter signal, so they dont actually know how much air is in there. They base their fuel load on vacuum/boost level, AFR, and a few others.. with my Megasquirt, I would be able to do that. You could do that, too, if you didn't need that AFM

i heard you bro, i was thinking of selling my safc and buying a megasquirt but i haven't seen a rotary running a megasquirt, i would love to but one but i want more info in a 7 that has one to make sure its goiing to be good the $$$$ lol. i sure hate that afm lol.

your bov isnt bypassing enough air.... its pushing the hoses off...
time to upgrade!

rx7legend

lol no man, i already have an upgraded bov i have a turbosmart, and the hose went off because i was checking some things out and i took of the ic and when i put it back i didn't tight the hose that hard and when i hit the throttle lol it went off, but i tight it real good this time so i don't think is coming off any time soon lol.

thanks for the help anyway bro
