will 19lb mustang injectors screw up my OBC

[ptownTSI]

i'd like to keep it accurate if possible but from what guys are telling me teh 19lb mustang injectors really do alot of good things for these old bmw's.

yes

Are they any wiring mods that you have to do??

[ptownTSI]

nando you did mention that your gas mileage went up a bit with the injectors so if anything the OBC will be reading low??

no, it still reads high. we are talking about like a 1-2% increase, which was probably just from switching to cleaner injectors. but the MPG will be off by 25-30% because of the reduced duty cycle; the computer still thinks you have stock injectors but it doesn't have to turn them on as often or for as long so it thinks you are getting better MPG than you really are.

as far as I know there is no way to fix it

Besides junking the econo meter and wiring in the ///M3 oil temp gauge.. hmmm???

Be sure you understand that the 19lb injector mod is only good for the M20B25 in the 325i and 325is.

If you have a M20b27 "eta" engine found in the regular 325, 325e or 325es then 19lb injectors will fry your DME from what I've been told due to the difference in impedence.

19#

Do the 19# give one any gain, really, on a stock (mine) setup?

Slightly, the more mods the more power difference.
Better mileage? Probably a small amout.

Just gives you a more reliable, newer, 4 pintle injector.

Before you install them, take them to get cleaned. It's worth it.
