10.5 AFR!! That’s what I was running!
I was tuning with a Haltech AF-30 narrow band and they are “supposed” to be pretty good. Since I was running so rich before, now my gas mileage should go up and the throttle seems way crisper. I’ll post my fuel values later (before and after) once I’ve fine-tuned them a bit better.
Wide band users! If you’re running an exhaust extension tube, your lambda is not getting hot enough for an accurate reading! Even if it is a heated unit…mine is.
The WMS wideband has an LED that lights up when it hot enough…It took almost 10 min. at the “Y” in my Ansa exhaust (with SSI’s) before I had a green “hot enough” LED. A header would most likely heat up way faster.
Did you tune your car via the Halmeter to be on the rich side, or was that after tuning to 14.7:1?
Is it just me? I have no idea what any of this means? Wide band - is that like my cable with Comcast? English translation - or better yet - the "For Dummies" version for the rest of us.
Hmmm.....
Seems like there's a problem with my wideband...I should have a green LED in 15 seconds...It's not heating up like it should.
Talked to Ross at SDS and they're going to Fed-Ex me another meter ASAP.
Of course it's a long weekend here this weekend.
Results on hold for now.

Mark - The wideband sensor should be able to heat up even with the car off, mine only takes about 30 seconds.
If it's not heating up your supply voltage may be too low at the controller, or the controller is not trying hard enought to heat the sensor (bad design).
The sensor will not work properly unless the lambda cell is HOTTER than the exhaust gas it is measuring. Totally different than narrowband.

10.5 to 1 is way way too rich....of course that is what my MS is reading....
I know that my WB02 gets hot very quickly. I drilled and installed a bung just after both pipes came together. Bursch exhaust.
Modern FI is the bomb...no matter which you are running..
Mark/Herb,
This is funny. I tuned with narrow-band to get things roughted in before getting my LM-1 wideband. Guess what. My narrow-band tuned AFR was about 10.5. That lambda curve sure is steep. Wideband rocks. They'd sell more of them if instead of sighting the technical aspects they just said "Buy this. It will fix your AFR, but more importantly it will save your marriage, your relationship with your kids, keep you from losing your job, and help you avoid being institutionalized."

My wife hates it when I am tuning in the garage....I am tuning for a 2.35v crossover point...
My car is rich rich rich.....it really stinks at 10.5. But Hey! it doesn't ping!!
My duty cycles are so low with the 2.0 injectors I'm going to try some smaller injectors....I think my buddy has some 1.7 injectors
What other injectors fit a stock injector holder?
My wideband is now hit and miss...same issue this AM but now it's working fine.
Bet it makes me look like a duffus when they test it..."Ummm.... dars nutin' wrong with it"

Thanks Ben
Nope...this engine is my stock orginal 1.8 with 75K on it. sold the 2.0
Still gathering parts on my 2.6 T4....still need TB's and a header...only $ in my way

Thanks Ben
I'll let You know once I've tried them...Maybe I should try my 1.8 L-jet injectors first.
