wish I had a scanner, heres the numbers.

6200----181.9---- 154.1---- 10.0

Looking at the graph now I see why it felt so bad after 3K.
need input on these numbers, and also what ratio does the fmu come with with the kit? I definately need to do something about the fuel, and need suggestions.

hey im in az also, ever go to kiwanis? and can you tell me more about your setup (b18b drag im guessing)... i am gonna do same thing

-sam

 

Is that showing a 10:1 A/F ratio???? Shouldnt your motor blow up? I know the DSM guys run around 13.x:1, I am at 12.9:1 but 10??


I'm sorta new here, so what are the major details of the system? If you can get your plot to Kinko's they can scan it, and I'll give you a free place to host the image...

13:1 is MORE DANGEROUS than 10:1.

He's running extremely rich and needs to lean out the A/F mixture a bit.

 

<-- foot in mouth

Oh, Duh! yeah, sorry...10:1 = MORE RICH than 13:1 ..sorry, brain fart... so, what I MEANT to say is, if you can perhaps bleed the signal to your FMU, (Grager valve?) you may be able to pick up some power up top.

 

lean your car to 12:1 you should pick up about 20hp easy.

 

lets see setup
97ls engine
drag 3 kit (using everything that came with kit)
7 heat range plugs
WS exhaust, no cat
act clutch
shitty a** tires, stock height

I dont go to Kiwanis, Ive heard a lot of bad stories about there. If you are serious about getting the kit and wanna check out my setup let me know.

So does anyone know what the ratio of the fmu is with the kit? Or can anyone suggest the correct ratio of fmu to use based on the readings. The guy I bought the kit from was running like 9-11 psi, so im thinking he was running with a higher fmu. I dont really have a means of leaning it out, im still using stock regulator and injectors. Any other means of leaning it out? thx for all the replies.

 

Go to an aquarium shop, and you can get a "granger valve (sp?) which would allow you to bleed some of the boost signal to the fmu. The dyno shop should know to to hook it up...shouldn't me more than aboot $10.

 

never heard of that, how reliable or how accurate would that be?

 

why does it only show RPMs up to 6200, the LS revs to 6800 right?

 

Hey but look at those torque numbers

 

Its very accurate, but youd need to tune it on a dyno...I know of a guy w/ a 626 with about 300whp who has been using a sim set up for years. basically, you just open the valve in VERY small incriments, to allow x amount of boost to bleed from the signal line to the fmu. I will dig around, and try to find detailed instructions for ya..
