hey i finally got a wideband and now that its telling me im at 10.9 at 7psi on a 60-1, with an rtek 1.7, what can i safely turn it up to? thanks

 

Probably not much more than that (safely). Try upping it to around 8-9 and see what happens. Just have a friend watch your wideband carefully and tell you if he sees you going past mid-11's. Be careful and allow yourself a little padding.

 

yea 10.9 is the highest number I've seen while under full boost. Usually its near 10.2-10.4 it kinda bounces a few decimals. Im glad to finally have a wideband, and cant wait to add more boost!!! wo you think 2 psi would be safe? im just curious what you guys think, cause you all have more experience with turbo RX7's than i do. Thanks!

 

im running a 60-1 hybrid @ 6psi, fmic, cold intake, 3" exhaust, rtek 2.0 and the afm is starting to max out. I can sort make up for it using the rtek, since the fuel map is referenced to boost. with rtek 1.7 i would think your afm will be maxing out soon, especially if it is a true 60-1 (not a hybrid). heres my log, check out where AFM levels off.. and this is only a 2nd gear run

 

Man.. I need a wide band...

 

uh dude you do know that the AEM UEGO gauge does not put out a fully linear 0-5v signal right? and the Rtek 2.0 needs a linear input? Your datalog is not fully accurate. That's why I sold mine and got an Innovate LC-1. This is something the power FC guys have run into.
