I just got back from the first run on my current build. The car is pulling great and idles fine. I datalgged the run and have a few questions about it as i am not sure on some things.

1 - BPW ms on the left side is always lower than the right side and highlighted yellow

2 - Short term counts on the left side drop to 1 for a period of coasting. It jumps up again as soon as i give it throttle

Can someone have a look at my datamaster file to see if anything stads out?
How ca i post the link to the file here so it can be viewed easily?

Thanks

 

shoot it over to me and I will take a look. What cam are you using?

email sent with file and cam specs

 

You at the very least need to get rid of your MALF 12 and 13 codes that are being thrown.

I cannot understand this file at all. It says you are running the car at 4000 RPM for 15 minutes with no variation except for TPS% I have never seen fuel trims of 220 and all the other numbers that pop up.

Since I am not sure of the 93's and Datamaster, someone else may want to chime in here but your data is basically useless to me in diagnosing what is going on.

 

no codes being thrown, no engine light and when i look at the datalog file on datamaster there are no DTC either...what version of datamaster are you using to view the file?

 

3.5.1. It says you are throwing about 10 codes. Sorry I cannot help you on this.

 

no problem, thanks for trying....what would cause split blms?

 

You have a big cam...bigger than mine. Big cams have this problem.

The way I solved my split BLM's at idle is the close the TB blades all the way (idle air screw) and drilled the idle air passage larger to keep my IAC from knocking on 160 constantly. The factory set up the plenum to run the idle air through the idle passages not the actual plenum itself.

I have the split BLM's at part throttle however and am working on tuning it out over time. Got other projects like painting the car...

 

I have another file if someoe can have a look...

 

send it over, I got a cammed 93 as well. I take a look.

Blackhawk, a '93 f-body LT1 requires DataMaster DM3.5.xDA software, ref: 'http://www.ttspowersystems.com/DataMaster_downloads.html ' are you running 3.5.xEE from the '95 Firehawk or some other version for the RX7 ?

 

yah bummer my Datamaster is for the 94-95's. My RX7 is also a 95 PCM.
