okay. Do you mind if we talk for a bit cnterline? I followed you on Instagram and dmed but never got a reply back 😂 but my goal is to follow in your footsteps and run 10s..I just want to make sure I prep my car correctly for that.
Is there anything I should do for my fuel system?
Run e85?
I definetly am considering running Nitrous after all of my bolt ons and maybe spray it off the line. Let me
know. Thank you.

Your a (mr.internet lawyer) ,centerline just said it lol..Your clown you can't add a larger injector without standalone in this car with it running correctly .You can't add one large with the rest stock and what you going to do scale on only??Love to see this on a stock ecu,.This forum I tell you are special people...Learn how this car works and report back on ecu ,injecotor and tables the ecu has to make the ecu work with it open loop.I dare to call e.c ask for jerry and ask him to tune larger 8 injector with the rest stock,you'll see how hard he laughs and hangs the phone up on you.These posts remind me of the 20 year back Honda days
What we are saying and that you seem to have a problem with is that if you again take your stock injectors, the ones that came with your engine, that ran it perfectly for 12+ years. You find out what they flow. I believe the stock ones are 412cc/min. Lets say all eight come back as 405, 410, 410, 411, 412, 417, 418 and 425cc/min because they are never going to be exactly the same, they are mass produced cars not F1 contenders. You then put the 425 back into number 8 cyclinder so it can run ever so slightly richer than the rest at the same fuel pressure. That way if you have a slight problem with fuel pressure then you have a tiny safety net before this cylinder blows.
Sorry for wasting everyone's time and being off topic (last time I promise), I respect this guys technical knowledge despite lack of social skills otherwise I wouldn't bother.
On topic, I would also be interested to know how they set up the SL55 fuel system.

I was just stating a fact that E55 runs dual fuel pumps in tank, SL55 is external pump ,I have no experience with E85;nitrous (which I don’t recommend for my own reasons) or methanol , do a search on here there are a bunch of 10 second cars ,there even a post titled 10 second recipe I believe lol.

Once again we all agree with you 100% that you cannot add a single *much larger* injector OR even a full set of larger injectors without compensating for the extra flow via the ECU. No one is arguing against you on this. We also agree that we don't have significant control over single injector fuel trims so a fairly advanced standalone would be needed if for some reason we wanted to do this (we don't!).
What we are saying and that you seem to have a problem with is that if you again take your stock injectors, the ones that came with your engine, that ran it perfectly for 12+ years.

I would like go further on this subject ,people like you don’t waste anyone’s time and like that your very interested seriously and not acting like a dumb ***
.Even if you did do that, that’s not the real issue going on with the fuel on cylinder 8 ,this happens more when idiots decide to do pulls back to back without cooling and running the car to 160 mph and which you can cause heat up to the stock pumps and more so on the recall done without the proper pigtail installed to correct the lean out .
Also, not to mention if your doing pulls like that Afr should be set to 11.2 that would help over come lean up.How many stock cars you see have cylinder 8 lean out and fail ??think about that and remember stock Afr dip into the 10 thst helps cool down Egt and saves the cylinder walls etc .

- People driving too agressivly causing fuel pumps to overheat and-
- Fuel pump updating/warranty work not correcting the reversed wiring on one of the fuel pumps.
Strange you are willing to tell TW2 what he mentioned(which was completely logical) is useless and then follow it up by saying such nonsense. I hope other people see through your bull **** and don't read the total crap you so confidently post and take it as knowledge.

You just said that cylinder 8 failure happens due to:

Well sorry to say ,this is the many reasons they Grenade there engine ,since your such a fool to figure that out not sure what to say .I could care less about your posts as they don’t count lol.If you can’t understand stand logic that if the pumps are wired incorrectly ,there tunes are very lean (higher in gears some tunes lean out ,get fuel pressure lose your a fool (you are still a fool regardless )not sure what to say .To correct this matters,make sure other people can have this check list ..
pumps are flowing proper and are in good working condition
Things to look out for
fuel pressure is in good state under wot
if modded larger are needed
injectors are clean and flow fine
tune is not to lean in higher gears and speeds
can add looped rail for Preventative safety
make larger rails custom to extra flow and more
Consistent fuel pressure..
larger flowing pumps (aem) this is a great combo if you want more fuel and e85 later down the road .
Larger injector to help my starve as mods come cAr will need more fuel from more air and power made so that your
injector duty cycle is not maxed out .When this happens your injectors get hot and Pulse slower and can seize them from heat from over straining them.

If youre not logging or Monitoring parameters youre definitely going to want to. It can give you insight on an issue before its too late. The best is to run dual widebands, but a single on Bank 2 is ok if thats all you can manage.

The best and most expensive fuel system fix is to convert your car into a return system with aftermarket pumps.
