yes 19lb injectors very goood, makes the car pull waaaay harder after 5000rpms, this mod should be combined with an M30 AFM, then the car will run bad for about 2-3 startups/drives, and then the ECU will fully adjust and the car will run amazing.(the stock ecu can adjust to injectors up to around 24lbs)

I also have 19# injectors...and it pulls really hard from 3500 to 5500

but that might also have to do with the turbo!

sorry i had to.

the M30 AFM has to have the part number ending in 027 and its plug and play. its around 3.125 outside diameter on each end so stretching of the intake boot will be needed and you have to run a conefilter(well, you dont have to if your creative.

I'm going to start running megasquirt so no more AFM for me. and then i want to supercharge the car,(i dont like how you have to run oil lines to the turbo).

at first it seems super overwhelming, but then i realized you can just buy plug and play ones from r3v or e30tech, it controls fuel and spark, and eliminates the AFM so you can just run a piece of pipe in the AFMs place, theres tons of updates for it you can make it so you have traction control, it controls all you boosting needs, you can control fuel curves and what not,you just plug it into your lap top and tune away, only problem is that its expensive. i think i found a plug and play one for $400 that i'm going to buy as soon as i get the money.

whoa..400. you make it seem tempting. but with the 400 for ME, i could put it towards an o2 sensor, TOB, lowering springs, rear shock mounts..and i think thats it. haha.

they're the injectors for your car. you have 6, well.you have a 4 cylinder so you have 4 of them. the bigger the # of lbs, the more fuel flow you'll get.

adding on to this, the stock injectors on the 325i are 14#.

i think i'll turbo my car and forget about megasquirt and supercharging, that TCD kit seems very tempting. it uses a turbo chip instead of megasquirt

ok i have a theory
i have 19lbs fuel injectors but stock afm
so i did a little bit of research and i found out the the M20 afm has a spring adjustment control soooooooo
can i make it less resistant making the car run lean causing the ecu to add more fuel witch = more power

do you think that would work or should i leave it alone?


sorry about jacking the thread but i thought it was kinda relevant

i know that the AFM i have is adjusted by the previous owner of it, but i don't think you should mess with the spring, but i know for a fact that when me car is running rich(adapting to the AFM and injectors) it runs alot faster than it does when it is fully adapted and not running rich anymore.
