(Hey folks, just posted here too cuz the Uber site is slow for responses):
It's not just on deceleration (I don't think), cuz I set the Min TPS Trigger to 12.
In the boost range, some numbers are okay, but some are 16.0, 16.4, 16.1, etc.
- 8.7 PSI
- 440cc Delphi injectors (42lb/hr @43.5psi, 320gm/min)
- PLX M250
- I followed the steps to get an LS basemap
- 110 fuel efficiency, .80 ignition retard
Things to try?
Anyone?
Uberdata ROCKS!

TRy to up your fuel efficeincy to 120, and add around 5% to the places where it is lean, and smooth it out from there, since I see you have a wideband.

Thanks. I was gonna try somthing similar, but it bothers me that the basemap was so lean... I'm almost suspecting my injectors, or duty cycle, I don't know.
Anyone else?
Thanks again man.

exactly. its a basemap. how acurate would you expect it to be ?

It was soo lean, because of your boost efficiency, it is also known that 1.7 is a little leaner for whatever reason. I believe because they changed something with the resolution, maybe I am wrong.

Hey, easy guys.
I don't expect the basemap to be perfect, but I DID expect it to be on the rich/safe side. Whoever said that 1.7 tends to be lean -- thanks --- THAT's what kind of info I was after.
Seeing 16's with a basemap made me instantly start to suspect my injectors, that's all.
Thanks for responding tho.

<-- Always starts with 120% effiecency.
Just for giggles, my Uberdata SOHC map was nearly *DEAD ON* on my first burn. Adjusted maybe 2-3% here and here for a linear A/F line, otherwise it was at least 98% accurate for boost right off the bat.

what turbo are you running... i have done a few cars with gt28rs's that required 150% efficecny to get in the right range... change it to 150 and work your way down from there.

120 efficiency, .9 retard, 50psi for the new fuel pressure setting, 450cc injectors. I was running on the lean side under boost. I bumped the fuel pressure on the car about 5psi to get the basemap on the rich side then started to adjust the maps from there. I could have also messed with the efficiency to achieve the same. hth
