I was wondering....

1. What A/F your car idles at
2. What A/F your car is when slightly boosting < 7 psi at NON-WOT
3. Is your A/F readout display a little sluggish in responding to actual A/F readings?
4. When you let off the gas does it display 25.(a 3 only the bottom right horizontal line is out when showing it)

 

mine idles around 19~20...my sensor has 300,000miles on in it though. have to buy a new one. have u checked the yahoo group? lots of info there http://groups.yahoo.com/group/oz-diy-wb/

 

I've built several of the DIY units now.

1) On one system, idle was 18-19afr (modded car, custom map, open loop) on a stock car (stock ecu) (~15 afr)

2) Havent tested on boosted cars yet

3) Yes, display is slightly slower then actual voltage reading with multimeter (no big deal)

4) Yes, when you let off the gas, the injectors are closed therefore it shows a lean condition >25 afr

 

idle is 14.7:1 exactly what i tuned my hondata to!!

 

Thats funny cause mine idles at that with my afc hack setup.... in fact it basically stays at that 14.5-14.8 mixture ALL the time until I'm at near or full boost when it shoots down to 11.9-12.8

Where do you purchase one of these Tech Edge W/b's from? I'm interested.

this is what the stock ecu idles and part throttle cruises at.

 

What is everyones ratio during boost but not full boost.... ex I run max of 8psi, but anything under that pretty much is 14.7 A/F.... well any boost under 4300rpms that is (when full boost hits) then its 12.something across the board.
