EE LT1 Wideband Input

[In-Tech]

This must be common knowledge because I couldn't find this all in one place anywhere, maybe this will help someone. I wanted and am using it on the EGR pin with a PLX wideband.



A/C Evap. Temperature (PCM Pin D24)
A/C Pressure (PCM Pin D12)
Engine Oil Temperature (PCM Pin D26)
EGR Feedback Counts (PCM Pin D27)

Pin D is Blue Connector

One frame before the transmission blew up :innocent2:

Hi Carl,

Don't know if I can be of help on your first post, just not sure what you are asking for. I can give you details of the scale/voltage/defaulting for each of the lines you post about. Is that what you are asking?

Too bad about the trans...

Hi Tom, I enjoy reading of all your hard work. I was only posting because of frustration finding the pins used for external wideband 0-5v input. I didn't build the car noted above so I wasn't sure what pins were already used. I do know I wasn't going to be using the EGR so I was on the hunt to figure out what that pin was :happy: Shown in the data screen, wideband is working great :)
Yeah the tranny kill was a hard call to tell the customer yesterday, still collect for my tuning time, then tell him it runs great, bring a flatbed :yikes:

the EGR feedback (D27) is a good pin to use as no vehicle actually uses the EGR feedback sensor for anything useful. the other inputs at the very least will probably turn your fans on in some configurations. there are other pins that can be used with some simple datastream patches as well but D27 just makes sense, since it affects nothing and is in the default datastream.

Thanks for the reply steveo,
When it comes back after the trans is fixed, I am looking forward to trying out your EEHack. I perused it on my win7 lappy and it looks really cool. I sort of remember flashhack won't work on a db9 serial and it doesn't. However, it worked just fine with my keyspan(ftdi) usb to serial adapter. I didn't play with it very long but it appears to be a windows problem and not with your software. I will check more later when the car comes back. I kept it simple on this first round using TunerCat and DataCat since I already have that on my XP lappy. Your stuff looks extremely cool and I so rarely get to play with LT stuff I am excited to experiment on the next round. Shoot, I still haven't been able to acquire a 94/95 LT '8051 for my test bench stuff :(
