Wideband "show`s it run lean with Dbilas ITB"

[Janne]

I installed today Innovate wideband-lambda and afr-meter to my car and now i it shows it runs lean? there is video 2 & 3 gear pull:

My e36 IS got: Dbilas itb, Dbilas chip, Eisennman (race) "catback", Bmc carbon CAI and Shrick copy intake cam.

I think have to do chip at dyno next.

You've got quite an upgrade package there!!  Everything you have listed will bring more "AIR" into and out of the motor. The only fueling change made was the Dbilas chip that you have. This chip only accounts for the ITB's and nothing more! You have better exhaust, cam and air intake now but nothing to compensate for all that air.

 You have a few choices: You can add a Fuel Pressure Regulator for more fuel, or put in slightly larger inj's, or put in larger inj's and tune a new chip for the motor with your specific set up. The first two are cheaper and should work well. If you tune a new chip you will most likely only be playing with fuel maps anyway because your timing is probably maxed out on the Dbilas chip for peak power already but only for the stock cams. You may want to tune a chip if you want every last HP.:-)

If you change out the inj's for freshly flowed inj's you might be able to get away with just that. I just had stock inj's flowed @ 204cc's.

Is this dangerous lean?
Does nobody know what injectors e36 318is have stock? I found this list at google: http://users.erols.com/srweiss/tableifc.htm

No, it is not dangerous lean, it is almost stoich, this mixture should give you best emissions but not best power and not best fuel economy

I try to fix the proplem with S50b30 240cc injectors, maybe next week.
