1998 camaro ls1 e85 conversion Hi
I would like to convert my camaro to e85 by putting biggers injectors and of course a new fuel pump. Is it enough or should I do an new engine module setup too? (hard to do here in France)
My injectors are 0280 155 725 which means (according to http://www.fuelinjector.citymaker.co...low_Rates.html ) 18.25 lbs/hr at 3 bars (me I have 4 bars in my fuel line). I was thinking to put some 28lb injectors and and a new fuel pump. What are thinking? This is for me a everyday car, I’m not searching for any performance..yet

Well I’ve got it all wrong my injectors are 0280155 752 not 0280155 725 that means they are 28lb at 3bar but me I have 4bar so this make them 32lb. If I want 30% bigger for E85 I think 36lb should be a good compromise because at 4 bars the 36lb are 41lb.
My question is how this will go without tune-up?

As HCI said, your current mods will affect your injector size as well.
Stock heads? Cam? Intake?

Well everything is stock on my engine. So you are saying that just with bigger injectors it won't work well? I was thinking that can be a simple way to run on e85, that the ECM will command the injectors like gasoline ones but they give 30% more.
Your pcm will still think it is running the 26lb injectors regardless of what size you put in. There is much more to injector dynamics than just the flow rate. Your commanded air/fuel will need to change as well as other settings now that you are running 105+ race fuel.

I'm just curious, why are you wanting to run E85 on a bone stock LS1? You do realise it won't hardly make any difference right? Combine that with having to find E85 pumps, significantly worse gas mileage, and having to change the fuel system, it hardly seems worth it

hi
I changed the fuel injectors with the bigger ones but the engine was running too rich ( engine default too rich came too) so I reduced the fuel pressure from 4 bars to 3,2 and the engine is running "well" now with 100 % ethanol. It "seems" to me that the engine have the same power, it takes a couple of liters more of gas, it starts wery well at cold temperature but its running very rich, idle at 1200 tr. When the engine is at normal temperature and I stop it for 15 minutes it's hard to start the engine, I have to try at least 2 times. I know that it's not the good way to run en ethanol but 'till I found a way to reprogram the engine module it's ok for me.

Y a LSX Calibration sur Paname, mais il m' à dit que le LS1 ne pouvait pas rouler à l'E85 alors que tout LS1tech prétend le contraire
