Does any one make a wide band 02 sensor that will work on a crossfire injection ?

Wouldn't you need to go to a custom computer set up like the EBL?

Yes and ebl flash makes a computer for the crossfire

HAM Board

Item Name: HAM Board (IN STOCK)
Item Price: $130.95
Item SKU: DCS00013

Shipping USPS Flat Rate: $12.50

IN STOCK
Product Description Convert the GM 127747 or 1228746 TBI ECM to be plug and play compatible with the existing stock CFI harness connection. No need to splice your stock ECM wire harness. Just install the HAM module into the new ECM, plug it in and you are ready for laptop tuning. (unsoldering and re-soldering procedures are required to the ECM board for installation, additional hardware and software may be required)

Try Zeitronix Zt2

They have both wideband output and narrow band output for stock ECM. Depending on the fuel grade - straight gas AFR=14.64, E10 AFR=14.08, E15 AFR=13.79:1 stoichiometric crossover AFR point can be shifted.

I don't understand your question then. If you upgrade to the EBL, you can use a wideband O2, just like in any other setup with the EBL. The EBL is not made specific for the Crossfire. It needs to be modified with a HAM board to connect it to the old style computer harness in the car.

EBL allows you to use a WB02 sensor in place of a NB or patch the A/F it reads into the datalog for observation.

dynamicefi.com has it all explained.

dude, i don't understand your question. I asked what WB 02 sensor will work with the crossfire not what WB 02 sensor will work with the ebl flash computer .

OK - cool stuff. I didn't even know this existed.

bump for what?

there's no real WBO2 that "works" as-is with the CFI PCM, because it is using a narrowband O2 input. the ZT2 has a built-in emulator for that, so it can read off its WBO2 and convert to NBO2 0-1V signal... but other than being able to shift this signal during conversion (i.e. you're able to control the stoich set point of the signal), i dont really see much of an advantage here.
i'm not sure what you're trying to achieve or gain with the usage of a WBO2 on a stock CFI PCM. might wanna let use know so we will be able to help you better.

.. or you can just get the later style PCM connectors, cut the harness and repin it for the EBL

i am going to use a wideband oxygen sensor with the ebl flash and cfi ham board

WB's will work on any engine efi or carbed.

If you want to provide feedback to stock 84 ECU wont work as the 84 ECU is not hacked or info not available to our DIY tuning community.

I happen to own a 1984 EFI engine in my current ride

i'm sure there's some way to use WBO2 input directly into your engine management system on SOME variants (megasquirt, bigstuff, or whatever it may be) - but the EMSs people are usually using on this board can only digest NBO2 (0-1V) input signals.
you can however use it to dial in and tune your EMS calibration with it, as well as logging the WBO2 signal as an analog input, sure.

What do you have for a 84 efi?

Started out with XRam and large injectors and 7747. Sold that and went to 7.4L TBI on Holley projection mani and same injectors but added EBL. Today next week adding port fuel motown SP and edelbrock 1000 TB.
