Tuned the car on E85. Has Moran 500S on it.
I have the BS3 injector size at 350. Cant remember do I move it up or down
to add more fuel. And how much I should move it.

You need to start with a base configuration file for methanol and learn the methanol target air fuel ratios.

Basically it will need more fuel everywhere, AE fuel, Cranking fuel, the target tables will be cut in half at least.

A good base file would help you out a ton.

What 02 sensor you running ?

What 02 sensor you running ?

Just running the reg one. Not the NTK alchohol one.
I like to tune by spark plugs.

From what I understand if you move the injector size it moves fuel everywhere.

Changing the injector constant isn't really the way to do it but it might technically work.

I havent even ran it down the track yet. I just base tuned it on the dyno with e85.
Was wanting to just get it close. Ill be fine tuning it at the track next month.

Good deal otherwise it's about 2k for the upgrade

You probably know this but double check your fuel pump too...
e85 is much nicer to bearings and still functions somewhat as a lubricant... straight meth does not...

You should set it for the correct injector flow rate so all the calculated fuel data is correct. Moran would be a good source for a base tune on BS3 and his injectors. He is a long time BS3 guru.

He's the one who told me to set it at 350lbs.lol

2X
If you move the flow rate around you can get yourself in big trouble.
IMO only change the flow rate of you change the injector or base fuel pressure.

Are you running something other than 90 psi base fuel pressure?

Good call, that would probally be why he said to run it at 350lbs.
He told me to run at 45psi on the e85.

 

[Delstar]

your have to check if your fuel pump will pump enough

Ok so crank the base fuel pressure to 90 psi, reset the fuel flow rate to 5259 cc/min.

Are you running Alpha N or Speed Density?

Bingo!!!! I rest my case, LOL!!! I am on 16inj, ProMag44, and NTK O2 or I would help you with the base tune. Not a bad idea to make a few dyno pulls and have it pretty damn rich so when you go to the track it will be closer to correct fueling in boost. A inertia chassis dyno just can't load the engine like the track will so even done like I said it will probably still need more fuel in certain areas. PM me your engine specs if you need help with the timing map, I can help there. Hope this helps.

The 500's turn into 350's @ 45 base.

Ok so what will sound like a pain in the ass is but it will get you started,,
Take your present map go cell to cell and use this conversion formula below.
I would suggest stepping all the Fuel map numbers by 10-15 and go from there,,
Methanol is pretty forgiving and will run even pig fat.
