I keep checking back every few weeks or so for results, and someone posting up legit proof that these are not junk that you have to idle super fat cause they're mis-matched, and that these really are 95% ID for 25% the price.

And nothing. just a bunch of people buying them and not doing anything

lol

They're OEM injectors on a car that has to idle like OEM and pass OEM emissions tests with only a little bit more displacement per cylinder than us. I think you're safe.

We have lots of cases reported on OEM ECU's operating OEM injectors that MS has trouble with. Horrible low end non-linearity, solenoid heat soak.

My guess is that narrow band control doesn't care about these issues, or the ECU tuning is much more sophisticated.

Point is, you can't assume OEM means good results from MS.

If you really want the info then do the work yourself? You're certainly capable of doing it.

I have only anecdotal evidence but my buddy runs these on his B5 1.8t Audi A4 and they worked well for him.

Oh and they work great on Honda K motors...at least under extreme racing conditions.

I have never driven a car with matched injectors, so I really couldn't say how these factory GT500 injectors compare to the aftermarket matched EV14's that are avaliable.

For $120 in parts it was well worth it.

Basically 0 issues with fuel since I got these in.
I run GT500 injectors, also without issues.

That sounds more like an failing of the MS or the tuner than the injectors.

So anyone running these with an MS3x want to post up all the setting they are using? I am going to be updating my MSQ in a bit and want to go with what is working for you guys.

Did I miss where someone said how they are fitting that top o ring in the fuel rail? It seems too big.

I also have installed and am running these. A couple issues I have run into that could just be my tuning. So advice or anything is appreciated.

My main issue is having the idle caught after a touch of throttle. It likes to die. I added fuel in the idle areas and that helped, but Autotune keeps pulling it out when I run autotune at idle. Another thing is after I snap the throttle shut it goes really rich and then slowly climbs back to stoich.

I think some good EAE would help my problem but I really have no idea how to correctly tune it.

Do you have a filter setup to not pull fuel under, say, 1,300 RPM while running autotune? It may be a band-aid but it made it a lot easier to figure out my idle.

I could. I was hoping for a non-bandaid solution.

It is recommended to do exactly as G suggests. Do not use autotune for idle. If your idle is not catching, that is not likely a VE issue, but rather a IAC target or dashpot setting.

Ok I'll try that.

Idle caught fine with RX-8 injectors, and catches fine with a bit more fuel in the idle area. I have spent a bunch of time tuning the dashpot and IAC settings.

Aidan. Yeah, just thought of that, the fact that you were already running on the Yellows. Good deal.

So to summarize-

Are all the P/N's in post #1 still valid? The ballerest spray pattern, etc?

FWIW
I kept losing a cylinder when I first started driving the car on these injectors. I wiggled the single pigtail I could reach, and it lost that cylinder too. I cut my pigtails and soldered them to the stock harness.

I have not had any idle issues due to the injectors. They are working great so far. I made a new harness with the EV14 connectors instead of adding additional failure points with a adapter pigtail for each injector. I am running these sequential with no issues at all. Well, I still have the same hot restart issue I have had with factory and RX7 injectors as well. Thats a different topic all by itself.

This is my GT500 injector DIY thread from a few months ago.

Ah, finally the data point I've been looking for!

Tells me I don't need to go to them to solve that issue. As long as the Yellow tops give me enough fuel, I won't need to spend more $$ on injectors.
