Help with Calc.VET on PCM Swap SBC

Do you have data for table B3701...?

Yes. See attached.

Do you have table B9021 (defined by cax file) for Minimum Transient Pulsewidth...?

Nope. Must not be in my OS.

B9021 is defined by cax file for your OS 12202088...

see post #12 here: 17699-need-B9021-for-01250003

you rename the file "cax a.cax" to "12202088.cax" snd move the file to C:\Program Files (x86)\EFILive\V7.5\Calibrations...

then when you open a new instance of the tunetool you will see B9021.

Thanks, Joe.

I was able to get this updated in my tune but.... even after reading all of the threads on it, I still don't know what it does!

I have logged about 6 hours of data over the past week and after all of this time thinking that the car was running pig rich under throttle, I can say without any doubt that it was running pig rich, but.... it wasn't because of the tune. I had 4 burnt plug wire boots and the plugs were arcing to the headers under load. I never checked this because the plug wires are literally brand new; I put them on within the time that I've been trying to tune. I'm going to have to build my own wire set so that I can have 90 degree boots and long enough wires to turn away from the headers and then go up to the coil packs. The cool sox I had also aren't very cool anymore, so I'm going to have to get new ones and I think I'm going to wrap the primaries of the headers to help hold the heat down. The headers are ceramic but oh well.. they're brand new and already discolored from running too lean so what do I care if they get too hot under the wrap? Next I'll need a tubing bender and a tig and some inconel tubing to build my own headers....

Thanks for all of the help. After I'm back up and running (mechanically sound) I'll check back in if I'm still having trouble.

Be careful with misfires... when a cylinder does not fire at all, the unburnt oxygen will cause the O2 sensor to register lean (i.e. unburnt fuel does not count).


I use the MSD wires with the bendable boots.

Yes, +1 on mechanically sound, this helps tuning to go better/easier/accurate.

I found that headers always seem to discolor, my silver-ceramic coated stainless Supermaxx's have turned to a dull grey.

I think steel headers are better because they are thicker (but they rust)... stainless headers tend to be made of thin gauge tube... I wish someone would start making heavy gauge stainless headers.
