Info from Zeitronics users.
Hey Guys,
I could use some information from those of you running the Zeitronics WB. I’m looking for info from a relatively stock car with the factory AFM, injectors, and no piggy back.
What I’m looking for is the a/f ratio’s in a few areas.
1. Idle range (850 rpm’s +/-). What is the dither range? (Eg. 14.3 to 14.8)
2. A/F ratio’s on decel with the car in neutral but rolling. For example, you’re driving @ 2500 rpm’s in 3rd gear and you are rolling to a stop. You have the car in neutral and the A/F ratio at first reads max lean when you close the throttle (injector shut off). At what Rpm’s during the engine decel do the injectors begin to fire and what it the A/F ratio at that point. How long does it take to get back to the A/F ratio’s seen at idle.
3. A/F numbers during off-boost part throttle (mild) acceleration (should be around 14.7 or so).
I just want to do some comparisons on a “stock” car. Any relevant info is appreciated. Thanks

[QUOTE=Bill]Are there any stock cars left on this board?[/QUOTE
Probably not many. Aftermarket chips and turbo's are okay and almost preferred (chips anyway). As long as the injectors and AFM are stock.

Good post Jeremy, it would be very nice if someone has those results on a stock car.
Unfortunately, im waiting for the next Zeitronix GB (sometime next month?) and i would have had it installed on my stock car (besides a teste pipe, which wouldn't make much difference) but you need the results much sooner than that.

My car is essentially stock. Only have a test pipe, guru chips and an adj. fpr. Lost my data files, so this is from memory:
1. stays on 14.7 the majority of the time and just occasionally blinks 14.9
2. need to check
3. pretty much stays on 14.7 unless I get a little more happy with the throttle. haven't gone much over 4000 without going to near full throttle, though.
Cruising on the highway reads basically the same as idle, iirc.
