Default Mafterburner Tuning

Hi All,

I have a Turbocharged 86 N/A with a Lindsey Mafterburner. The car runs really well but I'm trying to understand some Mafterburner theory. My car has the stock N/A DME with TPS, the TPS is connected to the Mafterburner. How does the TPS affect the Mafterburner other then selecting alternate maps? bear in mind I'm using a N/A TPS. Also I see 10.1 AF that to me fairly rich, how do these numbers look to others that have Mafterburners?

-36lb Injectors
-Adjustable FPR
-Turbo Fuel Pump
-KKK K26

Here is a snapshot of monitor session done yesterday.

Ok it looks like from the 2.6V to about 3 V you are way rich. 3V to 3.9V your ok. Last but not least 4V on you are lean. Do I understand this correctly that this is a previously an N/A car that has been turboed with no KLR??

Yes, this is turboed N/A with no KLR but I use a J&S Safeguard to control knock.

Thanks !!

Here is another sample.

Ill PM you the rest of the log. While logging I wasn't able to stomp on the gas and hold it there, I thing that can cause erratic values.
