1989 Turbo2 with the following:

550/1600 injectors
To4b .84 a/r w/ vtrim/ptrim compressor
Greddy FMIC
Running I think 45psi static fuel pressure
Walbro 255 lp/hp
Bonez High Flo cat
Boost guage shows 15psi
Its 90 degrees outside with a humidity of 50%, road surface temperatures are about 125+ degrees


You can see my A/F ratio on the logs with the Spare A/D input. Its 0-5v 10-20 a/f linear. 0v is 10:1, .5v is 11:1, 1v is 12:1 and so-on..

l.txt is a pull in 3rd and 4th gear
log.txt I think a 2nd to 3rd gear pull.

Rename these to .HDL and open with datalog software!!

 

I'm fairly certain its safe to pull the PLX300 just about now. Dont want that burning a hole in my pocket...

Any suggestions?

 

What would you want us to look at? What's going to burn a hole in your pocket?

 

i dont want to burn up the plx wb sensor.

What do you all think of my a/f ratio

 

I dont understand what do you mean by burning your PLX, and all your runs in the L log are under vacuum, even though your at 94% throttle, also looks like your TPS needs calibration.

Care to explain what your car is doing?

 

To see logs correctly you must load the map that correspond to the logs which we don't have.

I think he wants to know if his afr are safe enough to remove his wideband o2 sensor.

 

Well no, you dont need to have the original map, i was able to view his logs, but the problem is this:

Load is reading negative all the time, thus is this car NA or what?
Spare A/D is reading very low, close to zero V.
Throttle doesnt go to 100%, it stays at 94, needs recalibrating.

Those are the things i was able to observe in the "L.txt" file after i converted it to ".HDL" and viewed it on the E6K software.

 

Yes you need the map that corresponds to the log. At least on my e6k' software. I opened a log of my car running at 15 psi without loading the map and I don't see any positive pressure. If I load the map and the same log, everything is fine. It's a bit stupid but it's the way it works with my software.

 

I think you can start the software, change the map sensor to 3 bars. Then map sensor values will be fine. However throttle % will not match. I'm not sure about spare A/D.

 

Yes, you are totally right, its a stupid quirk, you actually have to have the map values setup the same way (or similar) to what the original map under which the log was made to view them propely.

Anyway, having set it up as a rotary FC map, i was able to view things properly and here is my simple and humble observation, you are running pig rich under boost (10-15psi), right?

What you need to do is simple, tune down the fuel to a more agreeable point. What kinds of AFR are you getting from your PLX, since we can only see voltage? In all the post you still havent told us what the PLX was saying, im thinking rich, so thats what's burning a hole in your pocket? gas consumption?
