Well I’ve been trying to do some street tuning with my Microtech LT-8 and Zeitronix wide band. The problem is I didn’t get the boost sensor from ZT because I didn’t think I needed it. I thought I would just log everything on the MT and then log the AFR on the ZT. Well I did that but it’s impossible to compare the logs. So I just ordered the boost sensor from Zeitronix, now I should be able to log: RPM, AFR, Boost/Vacuum and Lambda. I’m hoping that I can just log the ZT (log up to 9hrs) and then make the changes to the MT.

When I pull the turbo off and replace it with a hybrid, I will install the EGT sensor. Then I will be able to log that also.

So just a word of advice to LT-8 owners……get a wide band that will log AFR, and boost/vacuum, that should make tuning much easier.

I got the same setup and didn't get the boost sensor cause it cost so damn much however you can just look in the mt data logger and see what the boost is doing at what rpm and referance that on your zeitronix at any given rpm. Also you don't have to get there egt probe you should be able to get one of ebay for like 25 bux.

 

That’s what I've been doing but it’s just a little awkward. That works well if you are under boost but when you are not its hard to tell if you were accelerating or coasting. You really need to look at the graph to see if it is going up or down. I’m sure it can be done this way but I want to make it easier, so I figure if I can log RPM, boost/vacuum and AFR all together on one software it should be easier to tune. This way I can look at one graph, then find that same point in the MT and make the changes I need. I should also note that I’ve never done this before so I’m still learning.

I agree.

 

The boost sensor should be delivered today.
I let you know if it is truly easier.

 

ok, now I have a different problem....the ZT boost sensor reads 2" less than the MT.
I'm not sure about the boost readings yet, I'm just trying to tune the off boost maps right now. I tee-ed the ZT boost sensor off the MT sensor, so I thought I would get the same reading. I guess this will have to work.

 

i know this is an old thread, but ive been doing some research on the zeitronix.

i have the same zt2 and i am starting to data log because i am going to tune my car. I want to get the boost sensor it costs $109. how did it work out? should i get it?

im running a haltech e6k and will datalog the zeitronix and do the same you were doing. go back into the haltech and make the changes at the same rpm the datalog read lean or rich.

 

I just got the boost sensor but haven't used it yet. also got an egt probe so that now I can log rpm, boost, afr, and egts Not sure of the problem your having with it reading 2#'s differant.

 

let me know if your boost sensor reads the same as your EMS.

Thanks,
Bill
