Hi Guys,

I am hoping Shane will chime in on this one

The car is a 1G, FP3052,Tial 44, 3" turboback, FIC850, Supra pump, Aeromotive AFPR (43psi base), FP2 Cams, Magnus SMIM, Spearco 2-216, Tial BOV, MAFT (blow-thru), Built 6-bolt with Ross 8.5:1/Eagle, springs, retainets, Zeitronix WBO2, etc. etc.

I was out tuning the car. Did a few pulls starting at 3000rpms on 3rd gear all the way to 7000rpms on 4th. I am running about 21psi on 93 octane. Got the A/F ratio to be b/n 11.4:1-11.8:1 (4th gear). There is hardly any knock 0.4 degress (about 5-6 counts), but I get a ton of timing 19.1 to 21.3 degrees throughout 4th gear on the entire pull. EGTs are about 1550 to 1600 @WOT.

The advice I am looking for is what A/F shall I shoot for and where should I keep the timing ... basically what would you do to make this log look good.

I converted the log to a webpage so you guys can see it in your web browser. Here is a link:

I am logging the boost with AEM3.5 bar and the A/F with a Zeitronix WBO2 connected to the EGR and Baro inputs on DSMLink.
