Hey guys, I'm going to be doing the repin and swap from my '85 ECM to the 86-89 '165 ECM. Then I'm planning on getting a flash chip installed so I can easily datalog/tune on the go without burning chips. I'm doing all of this so I can tune my 350+Tpi swap that I did last summer.
My question is about O2 sensors. I've read about the LC1 from here on the boards, but I was wondering if there are any recommendations of other good Widebands, or if I'm even taking the right steps for tunning and if my O2 sensor should be first priority for tuning? I'm basically new at all of this, and was wondering where I should start after I swap the ECM in.
Thanks for any and all responses!

I use a AEM UEGO with good results, plus I got it at an unbeatable price new from the locat tuner shop.

Thanks guys! Those products seem great! I was under the impression that I was supposed to do all my data logging via the ECM which I was going to swap in, but according to Zeitronix, I can datalog with their ZT-2 it seems.
So does that mean I shouldn't worry about datalogging with my ECM, or should I do both? In order to actually make a change to my tune, I'd have to burn a new chip for the ECM based on my datalogs tho, correct? So, how do you guys do your tuning?
Having the WB in the datastream with the other engine data makes it much easier to line up the timeline of when things are happening.
Otherwide you have 2 files to try and see when you were rich/lean and figuring out when you were on the throttle and at what load/speed etc.
There are additional inputs to some WB kits that can add TPS, RPM, VSS etc.
The tradoff of using the ECM is logging speed is slow in comparison to the WB logging software but you need to run all the extra wiring rather than just adding the WB to the ECM.

Oh ok, thank you for clarifying that for me! So if I were to just get a wideband sensor to hookup with my ECM, what type of sensor alone should I get? The other ones that were mentioned above seemed packaged with all the datalogging equipment. I'm getting a good idea of all my options
