Whats up fellas, just chipped the P75 in my 94 Integra with a B20 swap, first time chipping a Honda ECU, it went really well. Started right up with no CEL at all!

Anyway, I hear many different things about the maps for a stock B20, mine ran fine for months on the stock LS maps but I did notice it would start pinging sometimes around 3-5k rpm. The motor is completely stock except for a cheapy 4-2-1 header and true 3" intake.

I'm using Crome for tuning and was wondering if any of you guys wanted to share notes, no I'm not looking for a free handout tune! I have to pick up a wideband here soon so I can get a good look at things but for now Its running pretty damn good on the LS maps which I smoothed out and added a little fuel.

What should my fuel pressure be with vac off, I'm getting conflicting answers.. Crome shows base pressure to be at 45psi?

 

I wouldn't be adding or subtracting any fuel without a wideband.

 

Set your base ignition timing to 16 degrees.
Make sure you sync the ignition timing to your EMS.

 

Base timing it set via the manual (16degrees) at least according to my light and the mark on the balancer. How do I go about making sure its "synced" to my EMS?
