MarkD chip + injectors = way too rich HELP!

[silversleeper]

I got my injectors from Nitro as well.. disappointed to see the Ford emblem on them though, but it is a more effecient injector. they were clean too! my stock ones had black gunk all over them.

so now i have two parts off a 5.0L stang, the O2 sensor, and the injectors... i dunno whats next?

Glad you liked them. As to the ford logo...doesnt matter.It could have a Ferrari logo and it wont matter.Pick any car company they dont make the injectors.90%+ of injectors are made by bosch.Thats what matters.

Also before people try prying manifolds off ford 5.0's. You wont ever find 4 pintle injectors on those cars look elsewhere in the ford family. Or contact me for clean tested ready to ship units as many members can attest. ;)

Does anyone know what the stock flow rate for the injectors on an '89 M30 is? I have a TMS chip. So, would the motor benefit from some 19 lbers?

Not all 5.0 motors had 4-pintle design II injectors (the only kind you should use).

Good point. I bought my 4 pintle 19 lb injectors from Nitro too, but I have yet to install them. I just saw on Mark D's website that he has a chip specifically for cars w/ the 19 lb injectors swapped in. Anyone here try it out yet?

~17.5.

No benefit.

No benefit.

Hmm, yeah not much difference there then. What about the 24 lbers? Anyone know whch ford cars those came out of? If not that's cool. I'll find out from some friends.

[Mystikal]

No benefit because the motor does not need more fuel.

Larger injectors are only an upgrade on the 2.5 because the stock ones are undersized. The only other BMW motor in a similar state is the 3.0 in the US-spec M3.

Are these* also balanced?

I bought my injectors from nitro. They arrived well packed in a timely manner and looked good and clean. They've worked perfectly thus far.

Many people have the chip made for 17 and 19 # injectors. (it's the same chip). You really only need 17# injectors, people use 19# since they can get those cheap ones for Mustangs)

Mystikal has the chip also.

Just installed my 19lbers. CEL light came on. Ive only driven for a mile or two. Exhaust smells really rich. I already have a regular markd 93oct chip. Should I just keep driving to get the ecu adapted or am i in danger of fucking something up?

yes drive it more.let it idle for about 5 minutes then flog it for a good 10-15 minutes and all will be ok.Otherwise if you pamper it will take days to adapt.

the man speaks the truth. This is the same setup i installed, same symptoms as you. ENJOY!
