Can wait to put these on my car next week, the FIC1000s were fantastic and now a little more room to grow with the E85. Jon was great can say enough about those guys.

So it's safe to say these injectors on the low side can handle 1000hp on e85?
Anyone else have runs these that can put in with they're experience?
(Sorry to pull this out of the grave)

On the data sheet, what information does it portray? I'm running the stock PCM on my LT1 and the tuning software is much less prolific when compared to the HPTuners type software. Basically, I have...
Right now I'm running 60# with a 2 bar MAP sensor and my own Speed Density Tune. The car runs great but I'm running out of injector at the higher boost levels I'm running (21psi)
Is there anything in the data sheets I can take away to apply to my LT1 PCM tuning parameters?
Thanks,
Dave
- Injector size - So if I have a 60# injector setup, I say it's 55 and it goes richer. If I say it's a 65 it goes leaner.
- Injector offsets - If I diminish these settings from stock, it reduces overall pulse width. If I increase them, it richens it up a bit. Mostly noticeable at idle.
- The usual tables of Power Enrichment vs RPM and Temp
- A/F ratios

I called Texas Speed & Performance yesterday and spoke to them about the data sheet. He said he wasn't sure if they came with a data sheet or not. He went on to say that...
If I get a data sheet with mine, I'll post it here so we can have a reference. Meanwhile, I'll continue to surf the net for the settings.
- They were being drop shipped from someone else
- He didn't know if they would include a data sheet or not and that most injector sites, with the exception of Injector Dynamics, don't provide a data sheet.

Okay, I've got it. Thanks FIC! If anyone wants a copy of the multi-tabbed spreadsheet (it depicts the LS1/LS6/LS2 family distinctly from the LS3 and LS7 family, along with separate tabs for E40, E67), let me know and I'll make sure it's emailed to you.
Thanks for everyones' help.

__I took out my mototron 60# and installed these 127# over the weekend in my boosted LT1. I still have the LT1 OBDI computer and the stock 3 bar Fuel Pressure regulator.
__Since I'm running a 2 bar Speed Density tune, for a baseline injector setting, I took my 60# tunes setting (60 x 41% = 24.9) and applied the 41% against the 3 bar poundage (109#) to get 45#. I also took the data sheets injector offsets and took an average of the 3 cells per row in the columns of of 20,25,30 KPA and applied them to the single column of offsets that LT1 computers have defined. I crossed my fingers and fired it up, and to my freakin' delight, the wide band immediately displayed 14.7. I realized that if it displayed that on a cold start, that would actually probably turn out lean once it was at operating temperature.
__Sure enough, after a moderate test drive, it was displaying "LEAN" on the wide band (20:1 or above). I pulled out the laptop, set the injector down two digits to 43 and loaded that.
__I had to drive from Albany to Rochester (249 miles one way) at that time so I loaded up the car and got on the freeway. Sweet lord,... at 75mph and 2,000 rpm it was usually at -14 to -15, depending of the levelness of the highway. At that specific KPA (27 typically) the wide band showed 14.7. At KPA above that, where the gauge would show -13 to -9, depending on load, the A/F ratio would trend a tad lean at 15.x and 16.x. I'll have to fatten up those VE cells.
__When I pulled off the freeway and went to idle at the toll plaza, the engine was once again going in and out of 'LEAN' and the idle was 'hunting'. It idled like some of those ProMods, where the idle escalates about 300 rpm, the drops back, repeating the cycle every second. This morning, I dropped my injector constant (thus fattening up the entire range) by 1 so it's now set to 41.997. This has nailed the hot idle issue and it's now 14.x, but attendantly, the rest of the KPA range is now a tad richer too. My -14/27kpa ratio is now 13.5 instead of 14.7 so I'll have to pull some numbers off those VE cells and get everything that is rich, where it belongs and everything that is a tad lean back to 14.x.
All and all, I'm over the moon about these injectors. When I get all the lean/rich details addressed, I'll start working on the WOT. I took a brief plunge to 12.5 psi this morning and she felt as strong as ever, maybe a tad more at that particular PSI. Since the rear of the car was trying to pass the front, my eyes were glued to the road, not the Wideband so I can't say what that portrayed just yet.

I made 1009 whp thru a high stalled th400 with these injectors at 40 psi base! Straight pump gas. They have tons of room. I was only 74-75% cycle duty. Looking for 1200+ whp soon

Nice to know! I've got my 2 bar Speed Density tune set now as far as idle, cruise and WOT AFR. One unexpected thing was that my DFCO is 'different' now than with the 60#. With the 60#, the DFCO was smooth as it transitioned from throttle to zero then back again. Now, it bucks quite a bit. I've dropped the DFCO enable/disable vs MAP down a couple of points and it's getting progressively better/smoother. Another few test drives/reflashes and it should be perfect.
Right now, I'm running the PT7675 but I have a couple of GT35's I hope to install this Fall. Nice to know I won't need to upgrade the injectors.

mightyquickz28, im glad to see these working with the stock lt1 computer and 2 bar tune!
i talked to you on another forum about them and you send a tune over, my tuner has been busy and can't get to it till the first of june but I can't wait to get these going!
Good Job!!!

Thanks! Yeah, I'm enjoying the car big time now, not having to worry about running lean at 21 psi.
