Can't get this right

[joecar]

Rough guide:

100 kPa == 14.5 psi == barometric pressure = WOT normally aspirated.

Stock cam idles at about 33 kPa == 5 psi.

Of course, BOOST = MAP - BARO (in both kPa and psi).

Good job on the 2 bar sensor,
Post your latest tune file and i will add a few changes for you to try.

You do have a wideband right ?

Here is the latest log and tune file. The car seems to run extremely well right now and it is very cool out at 60 degrees.

Okay, your all out off injector !
hit 136 % duty cycle on the injectors in the log and fueling goes lean.

Should be aiming for 80-85% duty cycle max, so you need bigger injectors for sure.

42lb/hr at least but for the few extra $$$ i would get 60's.

Made some changes to your tune for you, but i woudn't be beating on it to much till you upgrade injectors.

Thank You so much.... I get my bonus next weekend so I will be buying the Injectors soon after.
This car is actually fun to drive again!

Glad to help...

Also how did you scale the 2 bar Map sensor ?
just you were only seeing 3 1/2 psi boost in the log, thought maybe the scaling may be a little off.

as long as you followed the tutorial should be all good,

with key on, engine not running , log what map sensor reads with std sensor (map kpa)
install the 2 bar sensor, set c6301 to 190 and log again, map kpa should be the same (key on engine off) if not alter c6301 value up or down until it matches.

I did follow the tutorial to set up the map sensor, my boost gauge was only reading 3or 4 lbs of boost which I don't understand because it is set up for 6lbs and the headunit was just rebuilt less than 1k mi ago.
I will try out your updated tune today after I get the last plug in, I got seven in pretty easy but this last one is not too easy to get to.

Here is quick run around the neighborhood with your tune, it runs really good but seems to idling a little high.

Try this one,

just make sure you log AFR and knock and don't go WOT till you sort injectors.

+1 on the injectors. 99 Fbody has 26lb'ers. If you ever head up north we use EFI Live at our shop.
