Turbo ls1 2001 camaro

[Slogrn]

Just added a turbo, 80lb injectors. dual 255 walboro pumps wired too a switch, no more evap. return fuel system with a magnafuel 9950 regulator. i guess i just dont know where to start on tuning the car. alotta info on the forums so its over whelming to the point i might pay a local tuner to tune the car. the car does run and drive. terribly with th driving but idles fine, used sloppy mechanics base tune and dont know if thats going to help or hurt me. also the car has a 3 bar map and stock maf. dont know if i should go speed density or not.


thank you for anyones help. drive 1.hpl

Yes you need/want to go with speed density, you will outflow the stock MAF very fast and you need to be able to account of the boost with a 2-3 BAR OS.

[Slogrn]

I guess i really don't know where to begin. And should i run a 2 bar os or 3. Im running around 10psi

from my little experience. 2 bar is good for 14 psi or so and thats what im using.

[SultanHassanMasTuning]

get a map sensor, and post your file.

[Slogrn]

I have a 3 bar in it already. Which file the tune or log?

[Slogrn]

Also what should my maximum spark advance be around.

[5FDP]

Under what situation?

You can still run regular timing in normal low load area's just like a NA motor would but under boost you will not be able to run the 20-25+ degree's of timing like a NA.

If kind of up to the engine to decide what it likes and what fuel you are running. Figure a good starting point is 10-14 degree's under boost.

Sultan was saying to post your tune file.

Base Tune 1.hpt

[SultanHassanMasTuning]

base tune

must write entire


wait 30 sec after flash complete

switch off

wait 10 sec ign on

then start car and Base Tune 3bar OS base.hpt

[Slogrn]

Write entire i can always convert it back if need be for whatever reason right? Lol dont know why that scares me

[SultanHassanMasTuning]

because we applied a different OS it needs write entire

you can always go back and write entire no problem

write entire is only if your changing OS or going back to original os

than you flash normally

[Slogrn]

Ok. Thats a good base tune to start with?

drive 1 8-18-16.hpl




okay heres my drive today. shifts great. once you start getting the pedal the AFR starts shooting up and then the car sputters. where do i start

[5FDP]

It's doing this with the tune he made up for you?

Anyway you can include the wideband into your channels, that will help a ton with tuning.

[Slogrn]

Yep still doing it. Okay ill get that wired in too.

Drive 2 8-18-16.hpl




another drive

[5FDP]

I'll be honest, I can't tell anything bad with those logs.

With no wideband or even fuel injector information it's hard to see if it's running out of fuel or losing fuel pressure or even misfiring/breaking up on you. It didn't even get past 100 kpa and into boost.

You can drop the MAF pids from your logs too because this is speed density. Make sure you are running the right MAP pid too, so you can see above 105 kpa when you enter boost.

[Slogrn]

Map pid? Also i dont don't know why my fuel injector info isnt on there. Tomorrow ill try to log with the wideband. Im trying to learn its just overwhelming lol

[Slogrn]

Also take a look at the base tune he gave me the spark advanced table showing above 30 degrees when the rpms go up. I could be confused but that seems like alot
