Maxed out another set of injectors. Time for Bosch 210's?

Looking at logs from the stock ls3 and G3X combo, it looks like I will need more Fuel injector with the 427 and G4X blower combo. This will be my third time upgrading injectors, and I want it to be the last.

I've read a lot about the Bosch 210 injectors and it seems guys are using the injector data from ID2000's and having good success. The only problem I've found is people seem to have trouble getting them to idle perfect with regular pump 91/93 octane. However, with E85, they do well. I only run E85, so I won't encounter that problem.

1. Anyone here running them?
2. Are you on the stock ECM?
3. Where did you buy them from?
4. Which data did you use?
5. Does anyone sell them flow matched?

EDIT: Currently running FIC1300

Yes sir. Used one set on my last setup on strictly pump e85. Tons of injector left.

Currently have 2 bosch 210s per cylinder now with alcohol on the same sbe 6.0. I have them both wired to the same driver so they will fire together. I will be starting it up this week and don't suspect ill have any issues

Correct me if I am wrong, but i thought you ran an aftermarket ecm. No? Where did you buy yours? Im trying to avoid knock offs.

Thanks

Yes I'm using ms3 but there's no reason they can't idle nice on a 427 With a stock ecm

And vs racing to avoid knockoffs

First, my car has been down a long time. I start it every so often to cycle oil through it, but that's it.

I think I have the FIC 2100's and e85.

I've monkeyed with the idle off & on for a long time, so this is what I recall.

The min injector pulse has steps. At one step, the car starts and idles okay, but is actually rich (.85 lambda comes to mind)

The next step down the car runs at stoich, but then suddenly goes inexplicably lean.

So, if I were to take the time to fix my MAF/MAP values, I think it would idle just fine on that large of an injector. I have the FF sensor, so I suspect it wouldn't make any difference what fuel I'm using.

In short, it's ultra-sensitive to tuning. Injectors are usually 3+ms (roughly), but these have to run at .3ms (1/10 of normal) and still seem to handle it. I'm not sure if they'll handle .2ms though.

I have a LSX 427 with twin 68's. I'm running a ProEFI with the bosch 210's on E85. This pull was only 17psi and with traction control activated it only had 5* total timing...
IDC 48%

It's good practice not to exceed 85% IDC..

I've no doubt they're big enough. I just dont know if I can get them to behave with the stock ECM and HPTuners. I can handle some tuning, but it's not worth it, if its a never ending problem and driveability sucks.

Are you talking about the ESS kit? If so, I bought from ESS, but Ted handled my last tune. Looking for info on the bosch 210s tho.

EDIT: Currently running FIC1300
Yep running them
Yes stock ecu
Bought from fuel injector connection
Data from hours of time tuning
Yes they are matched from fuel injector connection

Their is no real data. being our ecu injector stuff is limited
