does opening the throttle help?

I just installed these the FIC 1050s two days ago and ran 91 oct for about 1 hour until I switched to E85. I had the start up issues as well with 91 oct but for E85 it turns over superquick. Way faster than stock injectors.

For e85 I currently have:

Scaling at: 713cc

Latency

4.69 4.464
7.03 3.264
9.38 1.800
11.72 1.104
14.06 0.864
16.41 0.600
18.68 0.432

Super fast startup, perfect idle, LTFT Low +/- .5%, still need to log Mid LTFT

Of course it does, the engine is being flooded. I'm going to log a warm start if the provided info doesn't work.

Logged a warm start yesterday... I was astounded at the results. Injector pulse width started out at 10.5ms, and duty cycle was 9%! The ECU is opening the injectors way too much. As the ECU slowly commanded pulse width and duty cycle to decrease, the engine started/stumbled to life. I am going to fiddle with the latencies and cranking IPW adder to see if I can fix this. I had an idea, and would like some feedback...I was thinking about zeroing out my IPW adder table after the vehicle is hot, and dialing in my cranking voltage latency so the vehicle starts well. I would then log a warm start to watch pulse width/duty cycle to determine what value I need to put into the IPW at the corresponding coolant temp level, then repeat on a cold start. This seems like the only way to make sure my latencies are as close as possible on startup.

I had the same issues on FIC1050's - warm started bad on pump gas but E85 was completely fine. I then switched to ID1000's and had warm starting issues with 2 different sets of those on both E85 and 93....

I tried every tuning tactic, mechanical part swapping, etc and never could correct the issue.....but good luck, a few of us have been where you are to the point of tearing our hair out - in the end swapping injectors was the only answer (as mrfred also said).

I finally switched to FIC1100's and no more starting woes - car starts great on both fuels and I have zero complaints now.

Ok I think I figured out what is going on here... That same log that showed 10.5ms of injector pulse also showed a battery voltage of 1.67v at the same instant of the long pulse. Only happens at initial crank for a split second, and battery voltage returns to normal 10-11v. I am thinking that one of two things is causing this. First, I could have a voltage drop in the circuit supplying power to the ECU, most likely the ignition switch. Second, it could be a software anomoly caused by v7. Only way to know this is if anyone else is having this issue with voltage dropoff with v7. For the meantime I decreased my 4v latencies to compensate, and the car starts fine. I'll do a voltage drop test on my ign switch when I get a chance.

I run the FIC 1050's without any major problems, although occasionally I'll get a stumble during warmup from the o2 feedback and it'll correct itself. Of course I'm also running SD so my VE tables allow a bit more adjustment than maf setups regarding fuel, but here are the scaling and voltages that work very well for me on 93 octane pump gas:

Scaling: 860
V_____ms

04.69 3.312
07.03 1.680
09.38 1.368
11.72 1.128
14.06 0.840
16.41 0.360
18.68 0.240

i got tuned 2 days ago with the FIC 950's and i am having the same issue on cold start only it takes about 5 cranks for it to start but it starts every time. if the engine is hot and i turn the car off then on it fires right up. I'm guessing the latency on cold start needs to be refined?

Sorry to bring back an old thread .... but it still has value.

I recently picked up a set of FIC 1050cc injectors and I'm looking for the most current settings for them.

I'm also trying to determine how to add cranking primer pulse to Tephra V7 as it doens't have it. A can I just cut and paste the data in the following link and have it work?

Those definitions will work for any 8859 ROM.

Injectors are in. Th car started just fine cold and started just fine back to back when hot. I let it sit for a few hours and sure as hell the start was soft and barely stumbled to life. I immediately shut it down and restarted it without issue.

So.... I've read the entire thread a couple times and I'm kind of stuck. I highly doubt the injectors are bad if they start fine hot and cold. I have yet to try any advanced fuel options but honestly I don't know where to start. Can any of you assist?

Prior to these 1050s I ran denso 720s and they started perfect every single time even with a wide range of voltage settings.

the issue is likely that several, if not all, have miniscule leaks that seep just enough to fill the intake with fumes to make hard warm starts. i hate to say it, but if you can't fix it by lowering the first pulse and cranking ipw values, i don't think you'll be able to fix it with any other tuning. i'd love to be proven wrong, but that's my experience with these and id1000s.

Jeff_Jeske

I have to be honest and I'm a bit fuzzy on the IPW thing. I mean stock values are +226-+3 but then I see posts like the one below stating they are using negative number of the same value??? https://www.evolutionm.net/forums/8034843-post70.html

Any suggestions on where to go from the stock values? I wish V7 had alternate items for these as then I could try different setting without the need to constantly reflash.

i think they meant to use the "-" as a hyphen. crappy punctuation. since the 1050s flow at twice the amount as stock injectors, for gasoline try halving the startup ipw values (both the first pulse and the cranking vallues). use the tables in my adv fuel control thread.

I've read the advance thread .... lots of information that I haven't quite absorbed just yet.

I've been trying to find the Injector Cranking Primer Enrichment table as my V7 doesn't seem to have it but as of yet I haven't seen it in a thread or at least it hasn't jumped out at me.

To this point I've only tweaked the following tables:
Inj Scaling
1008

Inj Bat Voltage
4.512
3.408
1.896
1.320
0.936
0.672
0.480

Cranking Enrichment IPW Adder Main
226.3
108.1
46.1
17.3
11.5
8.6
6.7
1.8
1.8


Here and there I see reference to the Injector Cranking Primer Enrichment table.... I'm not sure what values to change next. I'll reread the advance fuel thread again tomorrow. I'm disgruntled right now.
