3SFTE A/F Ratio advice Options

[digs]

Hi, can I ask those who have had experience in this what kind of ratios they expect to see runnning their 5sfte or 3sftes?

I have a wideband, which fluctuates around 14.2 to 15.3 at idle, and 13.5 - 15.1/2 ish off boost runs. The AEM wideband gauge does continually fluctuate though, going through various ranges constantly.

I did do boost run to see, and was measuring 12-13s on WOT. Only 2 runs as not sorted det cans yet so not monitoring detonation. No more boost runs till I work on that.

This is using 295cc injectors, stock pressure. I do have 460cc injectors available too, as well as an afpr, and have emanage blue fitted.

What is the expected values and also, should my wideband be CONSTANTLY fluctuating ? As I will have issues with street tuning as it is never on one value for long ? Or do you guys look for a range?

Any experience would be gratefully received and listened to.

Well, my e-Manage was able to retard and advance the timing how i wanted it, all the others i know around here are able to do the same and it works quite ok.
The part about the 2 ECUs is true and i don´t like it either, wich is why i`m running a EMS 6860 standalone right now in my Celica, so yes i have used a standalone myself.

Most cheap or affordable standalones dont realy have a usefull knock control, lots of them got something like this in the last years but i dont think its as good as a stock system, maybe on the expensive systems but they cost more than our cars ...

My Celi was running great with the e-Manage but i wanted more and the car is just for fun now so i decided to go standalone.

I don't know but the knock control module in the MS3X is quite good.
